2003 Pacific hurricane season, Seasonal forecasts
On May 19, 2003, the CPC published its forecast for the Central Pacific hurricane season. The forecast called for a slightly below-average level of activity in 2003, due to the same forecast of the onset of La Niña which would later prompt the low forecast for the Eastern Pacific.


2003 Pacific hurricane season, Seasonal summary
There were 16 named storms and 7 hurricanes during the 2003 Pacific hurricane season, which is comparable with the long-term averages. However, there were no major hurricanes (Category 3 or higher on the Saffir–Simpson hurricane scale); this was the first time this had happened in the eastern Pacific since 1977, and is well below the long-term average of four. The first hurricane, Ignacio, formed on August 24. This is the latest formation of the first hurricane of a season recorded in the east Pacific since reliable satellite observation began in 1966. Additionally, the accumulated cyclone energy (ACE) index for the 2003 Pacific hurricane season was 53.381 units in the Eastern Pacific and 3.265 units in the Central Pacific. This value was within the top 10 least active seasons on record.


2003 Pacific hurricane season, Seasonal summary
Whilst the total activity was below average, there was an unusually high number of landfalls in Mexico. A total of eight Pacific and North Atlantic tropical cyclones had a direct impact in Mexico in 2003, second only to 1971, when 9 did so. This is well above the long-term average of 4.2 Atlantic and east Pacific storms affecting Mexico. Five Pacific storms impacted Mexico, of which Hurricanes Ignacio and Marty both hit the state of Baja California Sur as hurricanes. Two other storms hit mainland Mexico as tropical storms and a third as a tropical depression. Three storms hit Mexico within a very short space of time, the Pacific hurricanes Nora and Olaf, and the Atlantic Tropical Storm Larry. As a result of the flooding caused by these storms, disaster areas were declared in 14 states.


2003 Pacific hurricane season, Seasonal summary
Activity in the Central Pacific was below average, with only one tropical depression forming in the basin and one hurricane entering the basin from the east Pacific. In addition, a third system, Tropical Storm Guillermo, weakened to a remnant low just to the east of the Central Pacific Hurricane Center's area of responsibility. Although activity was generally low, Hurricane Jimena was the first direct threat to the Hawaiian Islands for several years and a hurricane watch was issued for the island of Hawaii. Jimena passed to the south, but still brought tropical-storm-force gusts and heavy rain to the island.


2003 Pacific hurricane season, Systems, Tropical Storm Andres
An area of disturbance weather developed south of Guatemala near 10°N latitude on May 10 within a broad area of low pressure. After tracking westward, the disturbance became classifiable by the Dvorak technique on May 18. Following the development of a closed low-level circulation, the disturbance was classified as a tropical depression on May 19 well to the south of Mexico as it moved west and became a tropical storm the next day.


2003 Pacific hurricane season, Systems, Tropical Storm Andres
Despite increasing wind shear from an anticyclone causing the convection to become displaced from the low-level center, Andres obtained its peak strength with winds of 60 mph (95 km/h) by 1800 UTC on May 20. Increasing shear prevented any further development as the storm moved quickly west-northwest. On May 25, the shear and a reduction in water temperatures induced a weakening trend. Andres was downgraded to a tropical depression on May 25, became a post-tropical cyclone six hours later, and dissipated on the next day. The storm did not approach land.


2003 Pacific hurricane season, Systems, Tropical Storm Blanca
A tropical wave interacted with an area of disturbed weather that had lingered near the southwestern Mexican coast without showing any signs of organization during mid-June. Following an increase in organization, the combined disturbance was classified as a tropical depression early on June 17. The storm strengthened and became Tropical Storm Blanca 12 hours later. The storm moved slowly to the west and based on Dvorak intensity estimates, was believed to have reached its peak on June 18 with 60 mph (95 km/h) winds.


2003 Pacific hurricane season, Systems, Tropical Storm Blanca
Although Blanca never developed a true eye, at its peak there was a ring of convection resembling one. Under the influence of strong shear from the southeast, Blanca began to weaken and move erratically, although intermittent bursts of deep convection continued. The storm degenerated to a tropical depression on June 20 and a post-tropical cyclone on June 22. The remnant of Blanca were tracked for an additional two days. There were no effects from Blanca on land.


2003 Pacific hurricane season, Systems, Tropical Storm Carlos
Tropical Storm Carlos formed from a tropical wave that crossed Central America on June 20 from a tropical wave to the south of Mexico. After gradually organizing, the wave was designated a tropical depression on June 26. At noon on that day, the depression was Carlos quickly strengthened, developing a well-defined eye feature in the center of the convection. Based on the eye, it is estimated Carlos made landfall early on June 27 with peak winds of 65 mph (100 km/h), about 60 miles (95 km) west of Puerto Escondido or about 150 mi (245 km) east-southeast of Acapulco. The storm rapidly deteriorated to a remnant low, which persisted until dissipating on June 29.


2003 Pacific hurricane season, Systems, Tropical Storm Carlos
Carlos dropped heavy rainfall to portions of southern Mexico, peaking at 337 mm (13.3 in) in two locations in Guerrero. In northwestern Oaxaca, seven people were killed when the heavy rainfall triggered a mudslide. Mudslides were reported elsewhere in the state, and about 30,000 homes were damaged. Throughout its path, the storm affected about 148,000 people. Monetary damage totaled 86.7 million pesos (2003 MXN, $8 million 2003 USD). At least nine people were killed throughout the country and there was also a report of two missing fishermen.


2003 Pacific hurricane season, Systems, Tropical Storm Dolores
A tropical wave had entered the eastern north Pacific Ocean from Central America on June 30, and four days later, became classifiable by the Dvorak technique while the wave was centered 1,160 km (720 mi) south of Manzanillo. Convection developed within an area of low pressure embedded in a tropical wave as it moved west. The disturbance organized into Tropical Depression Four-E on July 6 1,205 km (750 mi) to the south-southwest of the tip of the Baja California Peninsula.


2003 Pacific hurricane season, Systems, Tropical Storm Dolores
It soon strengthened further into Tropical Storm Dolores as it moved to the northwest and reached its peak as a minimal tropical storm with winds of 40 mph (65 km/h). However, east-northeasterly shear had an adverse effect on Dolores, with the low-level center becoming exposed on satellite imagery and it weakened back into a depression 12 hours after becoming a tropical storm. The northwest motion caused by a mid-level ridge north and northeast of the cyclone brought it over colder water and it degenerated into a post-tropical remnant low on July 8, with full dissipation occurring on July 9.


2003 Pacific hurricane season, Systems, Tropical Storm Enrique
On July 6, a tropical wave entered the northeastern Pacific Ocean from the coast of South America. A low pressure system then developed and began to show sins of organization on July 9. The depression was designated Tropical Depression Five-E midday on July 10 while located 650 mi (1,045 km). The storm became more organized and was named Tropical Storm Enrique the next day as it tracked west-northwest. The storm continued to strengthen and at one point was forecast to briefly become a hurricane.


2003 Pacific hurricane season, Systems, Tropical Storm Enrique
This did not occur as the storm reached its peak strength with 65 mph (100 km/h) winds, an intensity it maintained for 24 hours. The storm's relative high latitude of formation for that time of year and northwestward track resulted in limited time for Enrique to strengthen before encountering significantly cooler water associated with the California Current late on July 12. Due to the cold water temperatures Enrique rapidly weakened, despite low wind shear. The storm degenerated into a remnant low late on July 13 and continued to move west before dissipating after a further three days. Enrique had no effects on land, but there were two ship reports of tropical storm force winds, although these measurements did not pass quality control.


2003 Pacific hurricane season, Systems, Tropical Storm Felicia
A tropical wave passed over Central America on July 12 and started to become more organized two days later, which prompted Dvorak satellite estimates. Following a further increased in organization, the NHC designated the system a tropical depression on July 17 as it continued to move to the west. Tracking south of a subtropical ridge, the depression became Tropical Storm Felicia the next day and as there was initially low shear over the system, the NHC predicted that it would become a minimal hurricane.


2003 Pacific hurricane season, Systems, Tropical Storm Felicia
However, the storm remained disorganized and peaked with 50 mph (85 km/h) winds late on July 18. The storm gradually weakened under increasing shear as it headed west, weakening back to a tropical depression on July 20. After a west-northwestward turn, The remnant low entered the central Pacific before dissipating on July 24 well to the east of Hawaii. Felicia had no effect on land.


2003 Pacific hurricane season, Systems, Tropical Storm Guillermo
A tropical wave entered the eastern north Pacific Ocean on August 1 and began to show signs of organization three days later. A weak surface low developed within the tropical wave on August 6 and the convection associated with it became more concentrated. The circulation of the system became better defined and a Tropical Depression, Seven-E, formed early the next day. Although the depression was initially forecast to dissipate quickly, it became more organized as it moved to the west. On August 8, the depression was upgraded Tropical Storm Guillermo.


2003 Pacific hurricane season, Systems, Tropical Storm Guillermo
Later that day, Guillermo reached its peak strength with 60 mph (95 km/h) winds that day. It maintained this strength for a full day, until outflow from the developing Tropical Storm Hilda 690 mi (1,110 km) to its east disrupted its convection. Continuing westward, Guillermo weakened into a tropical depression on August 11. After the wind shear direction shifted westerly, all the deep convection collapsed on August 12. The remnant low entered the central Pacific shortly before dissipating on August 13.


2003 Pacific hurricane season, Systems, Tropical Storm Hilda
A tropical wave developed persistent thunderstorm activity on August 5, which soon became more organized, forming into Tropical Depression Eight-E to the south of Cabo San Lucas. An impressive outflow pattern caused the NHC to predict an intensification to hurricane strength, but strong easterly shear affected the system. The depression became Tropical Storm Hilda on August 10 but did not get any stronger than a minimal tropical storm with winds of 40 mph (65 km/h). Hilda moved west-northwest before it moved over colder waters, which caused it to weaken. Low-level flow forced the weakening cyclone westwards and it dissipated on August 13, having never approached land.


2003 Pacific hurricane season, Systems, Tropical Depression One-C
The only tropical cyclone to form in the central Pacific proper in 2003 developed on August 15, and resulted from an interaction between remnants of Tropical Storm Guillermo and a non-tropical low. Unfavorable wind shear prevented the development of the depression and weakened as it drifted to the west. It weakened to a post-tropical remnant low on August 17 and never regained depression strength. The remnant passed just south of Johnston Atoll before it crossed the International Date Line on August 20. The storm had a minimal effect on the weather of the Hawaiian Islands.


2003 Pacific hurricane season, Systems, Hurricane Ignacio
A tropical wave organized into a distinct area of disturbed weather just south of the Mexican port of Manzanillo, on August 22 and gradually moved to the northwest. It became Tropical Depression Nine-E off Cabo Corrientes two days later while it was located about 115 mi (185 km) west of the Mexico mainland or about 220 mi (345 km) southeast of the southern tip of the Baja California Peninsula. Under the influence of favorable atmospheric conditions steadily strengthened and obtained tropical storm status on August 25.


2003 Pacific hurricane season, Systems, Hurricane Ignacio
Early on August 24, Ignacio attained hurricane status, marking the latest formation of the first hurricane of a season recorded in the East Pacific since reliable satellite observation began in 1966. Ignacio reached its peak intensity on August 26 as a Category 2 hurricane on the Saffir-Simpson scale, with winds of 105 mph (165 km/h). Ignacio tracked northwest across the southern Gulf of California and began to weaken due to land interaction before it made landfall at an intensity of 80 mph (130 km/h) just to the east of La Paz. Ignacio weakened overland and dissipated early on August 28 over central Baja California.


2003 Pacific hurricane season, Systems, Hurricane Ignacio
The slow motion of Ignacio produced heavy rainfall across the southern portion of the Baja California Peninsula, including a peak 24‑hour total of 7.25 in (184 mm) in Ciudad Constitución, which resulted in severe flooding and drought relief. The passage of the hurricane left citizens in Todos Santos without power for around 24 hours. The closed roads and the airport in La Paz. Overall, Ignacio was responsible for approximately US$21 million of damage. Two rescue workers drowned in the flood waters brought by the storm and some 10,000 people were evacuated to shelters. Six municipalities in Baja California were declared disaster areas, The remnants of Ignacio produced thunderstorm activity in high terrain areas of central interior California, resulting in 3,500 customers losing power, 14 forest fires, and over 300 lightning strikes.


2003 Pacific hurricane season, Systems, Hurricane Jimena
On August 28, an area of disturbed weather within the Intertropical Convergence Zone developed into Tropical Depression Ten-E, some 1725 miles (2775 km) east of the Hawaiian Islands following the development of a closed low-level circulation. The storm began to steadily intensify as it tracked over warm ocean waters, attaining tropical storm status at noon. Shortly after developing an eye, Jimena was upgraded into a hurricane on August 29. The storm moved to the west, entering the central Pacific as it continued to strengthen.


2003 Pacific hurricane season, Systems, Hurricane Jimena
After reaching its peak strength with 105 mph (165 km/h) winds 800 mi (1300 km) to the east of Hawaii it began to weaken as a result of increased shear. The storm passed about 120 mi (195 km) to the south of the southern tip of Big Island on September 1, just after losing hurricane strength. The storm then moved west, south of the archipelago while continuing to weaken due to a combination of shear and a more stable air mass, with Jimena weakening inyto a tropical depression on September 3. The weakening Jimena crossed the International Date Line before dissipating on September 5.


2003 Pacific hurricane season, Systems, Hurricane Jimena
Forecasters at the Central Pacific Hurricane Center issued a hurricane watch for the Big Island on August 31 at 00:00 UTC. The storm brought 6 to 10 in (150 to 250 mm) of rain and 11 ft (3.3 m) surf to the island of Hawaii, resulting in minor flooding on the eastern side of the Big Island. There were also tropical storm force winds recorded on several of the Hawaiian Islands, which knocked down trees and damaged power lines, resulting in 1,300 residents without electricity.


2003 Pacific hurricane season, Systems, Tropical Storm Kevin
A tropical wave entered the northeastern Pacific Ocean on August 21 but remained devoid of any convective activity until August 28. A road surface low developed on August 29, but convective activity remained poorly organized. Tracking west-northwest around the western periphery of a ridge over Mexico, surface pressure of the system gradually fell, and by September 3, the disturbance was organized enough to be classified by the Dvorak technique. At noon, an increase in Dvorak estimates prompted the designation of Tropical Depression Eleven-E on September 3 roughly 345 mi (555 km) south-southwest of the tip of Baja California.


2003 Pacific hurricane season, Systems, Tropical Storm Kevin
The broad wind field prevented significant intensification and the system developed at an unusually high latitude, which placed the cyclone closer to cooler waters. The depression reached tropical storm strength on September 4. Although wind shear was light, Kevin weakened into a depression after just six hours, as it moved over colder waters as Kevin became less organized. On September 6 the system degenerated to a non-convective low-pressure area, which managed to survive for four days before finally dissipating. Tropical Storm Kevin had no effects on land.


2003 Pacific hurricane season, Systems, Hurricane Linda
A tropical wave crossed Central America and entered the northeastern Pacific Ocean on September 6. Convection began to increase in a tropical wave on September 9 and three days later a broad surface low developed. Midday on September 13, the disturbance organized into Tropical Depression Twelve-E about 390 mi (630 km) to the southwest of the Mexican port of Manzanillo. The cyclone moved to the northwest and was classified as a tropical storm on September 14. Linda steadily intensified as rainbands increased and upper-level outflow expanded.


2003 Pacific hurricane season, Systems, Hurricane Linda
On September 15, Linda was upgraded into a hurricane while also reaching its peak strength of 75 mph (120 km/h). The NHC predicted further slight traditional strengthening, but this did not occur and Linda weakened back to a tropical storm after just 12 hours as a hurricane. As the storm continued to weaken it turned to the west and then to the southwest, becoming a tropical depression on September 17. The remnant drifted to the southwest and finally dissipated on September 23. There were no reports of any effects from this storm.


2003 Pacific hurricane season, Systems, Hurricane Marty
A tropical wave moved into the northeastern Pacific Ocean on September 10 and the convection associated with it gradually increased. By September 19, while the system was south-southeast of Cabo San Lucas, it organized into Tropical Depression Thirteen-E. The depression strengthened as it headed towards the Baja California Peninsula, becoming a tropical storm on September 19 and a hurricane two days later. Marty began moving north-northwestward in response to a high pressure ridge to the west, and continued to strengthen, reaching a peak intensity of 100 mph (155 km/h) early on September 22.


2003 Pacific hurricane season, Systems, Hurricane Marty
Marty then moved northward at an increased speed before making landfall 10 mi (15 km) northeast of Cabo San Lucas. After moving over the southern tip of the peninsula, Marty moved up the western coast of the Gulf of California, gradually weakening as it did so. The storm weakened to a tropical storm on September 23 and a tropical depression later that day. After  making a second landfall near Puerto Peñasco as a tropical depression, Marty dissipated two days later after meandering over the northern Gulf of California.


2003 Pacific hurricane season, Systems, Hurricane Marty
Hurricane Marty was the deadliest storm of the 2003 Pacific hurricane season and was responsible for 12 deaths and either damaged or destroyed over 4,000 homes. A 5-foot (1.5 m) storm surge flooded parts of La Paz, and sank 35 yachts moored in various ports. Five people drowned after their cars were swept away by floodwaters while trying to cross a flooded stream. The floods also damaged 4,000-6,000 homes and buildings and significantly disrupted water and communications for an extended period of time. Overall, 6,000 people were affected and total damage from the storm was $100 million.


2003 Pacific hurricane season, Systems, Hurricane Marty
Overall, 6,000 people were affected and total damage from the storm was estimated at $100 million, making Marty the costliest east Pacific storm of the year. Two more people died when a tree fell on a car in Sinaloa. The outer bands of Marty brought dropped locally heavy rains to extreme southwestern Arizona, but there were no reports of flooding.


2003 Pacific hurricane season, Systems, Hurricane Nora
A tropical wave moved over Central America on September 25 and moved parallel to the south Mexican coast. It became more organized on October 1 and developed into Tropical Depression Fourteen-E to the south of the Baja California Peninsula. It continued to strengthen as it moved northwest in favorable conditions, becoming a tropical storm the next day. On October 4, it became a hurricane and reached its peak that day as a mid-level Category 2 hurricane with 105 mph (165 km/h) winds.


2003 Pacific hurricane season, Systems, Hurricane Nora
Nora made a sharp turn to the east and began to weaken, as the result of the influence of a mid-level trough and the outflow from Hurricane Olaf to the southeast. The cyclone rapidly weakened before it made landfall just north of Mazatlán, on October 9. Nora dissipated over land soon after landfall. Nora dropped locally heavy rainfall near landfall, peaking at 3.75 in (95.3 mm) in Mazatlán. Moisture from the remnants of Nora and Olaf interacted with an upper-level low to produce heavy rainfall across Texas, producing flooding near Waco that forced a family to evacuate.


2003 Pacific hurricane season, Systems, Hurricane Olaf
A tropical wave located to the south-southeast of Acapulco spawned a low-level circulation on October 2 and developed into Tropical Depression Fifteen-E the next day. The depression strengthened into Tropical Storm Olaf six hours after forming as it moved to the northwest in a low shear environment. Olaf  reached its peak strength as a minimal hurricane with 75 mph (120 km/h) winds on October 5 and developed a partial eyewall. The storm soon became disorganized and was only a hurricane for six hours as increased wind shear took toll on the storm. Olaf before turning towards the Mexican coast and re-intensified slightly before making landfall near Manzanillo on October 7, with winds of 60 mph (95 km/h). The next day, Olaf dissipated overland.


2003 Pacific hurricane season, Systems, Hurricane Olaf
Olaf dropped more significant rainfall to Mexico than Hurricane Nora, resulting in severe flooding in the states of Jalisco and Guanajuato which damaged crops, roads and over 12,000 houses. However, there were no deaths as a result of Hurricane Olaf.


2003 Pacific hurricane season, Systems, Hurricane Patricia
A tropical wave crossed Central America on October 17. Over the next few days, deep convection slowly become more concentrated and became classifiable via the Dvorak technique at 23:45 UTC on October 19. On October 20, the system was designated a tropical depression while located to the south of Acapulco. Following an increase in banding features in all quadrants, the depression was upgraded into Tropical Storm Patricia at 18:00 UTC that day.


2003 Pacific hurricane season, Systems, Hurricane Patricia
After an eye became apparent on satellite imagery, Patricia was classified as a hurricane at noon on October 21, as it moved further west-northwest, steered by east-southeasterlies caused by the presence of a deep layered ridge to the north of the cyclone. Twelve hours later, its winds were increased to its peak intensity of 80 mph (130 km/h), though this estimate was slightly below than Dvorak-derived satellite intensity estimates. Although the NHC forecast further strengthening, with the Geophysical Fluid Dynamics Laboratory model forecasting Patricia to turn towards Mexico as a major hurricane, this did not occur.


2003 Pacific hurricane season, Systems, Hurricane Patricia
An upper-level trough over the Baja California Peninsula resulted in westerly shear over Patricia, which caused the low-level center to become displaced to the west of the deepest convection. This structure prompted weakening, and on October 22, Patricia was downgraded to below hurricane strength. Patricia continued to weaken until around noon on October 24, when the shear relaxed slightly, resulting in shower activity increasing over the center again. Consequently, Patrica briefly restrengthened slightly.


2003 Pacific hurricane season, Systems, Hurricane Patricia
Later on October 24 , the system turned toward the northwest in response to a weakness in the ridge caused by the trough near the Baja California Peninsula. The storm weakened further to a depression on October 25 as it lost all its deep convection, and it dissipated the next day around 600 mi (965 km) south-southwest of Cabo San Lucas, ending the season. Hurricane Patricia had no effects on land.


2003 Pacific hurricane season, Storm names
The following list of names was used to name storms that formed in the northeast Pacific in 2003. Names that were not assigned are marked in gray. No names were retired by the World Meteorological Organization, therefore this list was used again in the 2009 season. This is the same list which was used for the 1997 season except for Patricia, which replaced Pauline.


2003 Pacific hurricane season, Storm names
For storms that form in the Central Pacific Hurricane Center's area of responsibility, encompassing the area between 140 degrees west and the International Date Line, all names are used in a series of four rotating lists. The next four names that were slated for use in 2003 are shown below; however, none of them were used.

2003 Pacific typhoon season
The 2003 Pacific typhoon season was a slightly below average yearlong period of tropical cyclogenesis exhibiting the development of 45 tropical depressions, of which 21 became named storms; of those, 14 became typhoons. Though every month with the exception of February and March featured tropical activity, most storms developed from May through October. During the season, tropical cyclones affected the Philippines, Japan, China, the Korean Peninsula, Indochina, and various islands in the western Pacific.


2003 Pacific typhoon season
The season ran year-round, with the first storm, Yanyan, developing west of the Marshall Islands on January 15. In April, Typhoon Kujira became one of the longest-lasting Pacific typhoons in history and attained climatological records for its unusually early impacts. Typhoon Imbudo in July caused several deaths and extensive damage across the Philippines and China. In September, Typhoon Maemi became one of the costliest typhoons in recorded history after striking South Korea; Maemi was also the most intense tropical cyclone of the season with a minimum barometric pressure of 910 mbar (hPa; 26.87 inHg). In late November, Typhoon Lupit devastated areas of Yap State in the Federated States of Micronesia. The season closed with the dissipation of a tropical depression east of the Philippines on December 27.


2003 Pacific typhoon season
The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 2003 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin are assigned a name by the Tokyo Typhoon Center. Tropical depressions in this basin monitored by the Joint Typhoon Warning Center (JTWC) have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.


2003 Pacific typhoon season, Seasonal forecasts
On March 5, 2003, meteorologists from the University College London at the Tropical Storm Risk (TSR) Consortium issued an extended range forecast for the typhoon season, noting the likelihood of near average tropical cyclone activity as a result of projected neutral sea surface temperatures. The forecast indicated the potential for 26.2 tropical storms, compared to the 10– and 30-year average of 27.8 and 26.3 storms, respectively. The following month, the group raised their forecast for tropical storms to 26.7, indicating a slightly above average season.


2003 Pacific typhoon season, Seasonal forecasts
Over next two months, however, fluctuations in sea surface temperatures, particularly those in the Central Pacific, caused the group to revise their predictions downward and indicated the probability for a slightly below average typhoon season in their June forecast. A rise in sea surface temperatures in the following months prompted the forecasting group to once again raise their forecasts to indicate a near-average season in their final August forecast update, which predicted 27 tropical storms. The group was very accurate in their forecasts, with their April and August forecasts being the most accurate.


2003 Pacific typhoon season, Seasonal forecasts
Similarly, meteorologists working with the City University of Hong Kong issued a seasonal projection on April 24, 2003, indicating the likelihood of a normal or below normal season with 29 total tropical cyclones, 26 tropical storms, and 16 typhoons. As with the TSR, the group primarily based their forecast numbers on the prevailing status of the El Niño-Southern Oscillation. The City University of Hong Kong revised their forecasts on June 24, 2003, indicating a slight increase of total tropical cyclones to 30. The group was also accurate in their forecasts for the entirety of the Northwest Pacific, though their specialized forecasts for the South China Sea were substantially off.


2003 Pacific typhoon season, Seasonal forecasts
During the year, the Japan Meteorological Agency (JMA) issued advisories on tropical cyclones west of the International Date Line to the Malay Peninsula, and north of the equator; this was due to the agency's status as the official Regional Specialized Meteorological Center, as designated by the World Meteorological Organization in 1989. The JMA issued forecasts and analyses four times a day, beginning at 0000 UTC and continuing every six hours. The JMA issued forecasts based on a climatological tropical cyclone forecast model.


2003 Pacific typhoon season, Seasonal forecasts
The agency estimated 10 minute sustained winds and barometric pressure based on the Dvorak technique and numerical weather prediction. The JTWC also issued warnings on storms within the basin, operating from Pearl Harbor in Hawaii to represent the interests of the United States Armed Forces in the Indian and Pacific Oceans.


2003 Pacific typhoon season, Season summary
Throughout the season, sea surface temperatures within the western equatorial Pacific were above normal, including those in the South China Sea. Areas of convection persisted year-round in the lower latitudes, particularly around the Philippines. Atmospheric divergence was also prevalent in the same regions, resulting in enhanced tropical cyclogenesis east of the Philippines in 2003; the mean region of development of tropical systems during the year was more southwest than the 1971–2000 30-year average. In 2003, the JMA monitored 21 tropical cyclones of at least tropical storm intensity; of those, 14 reached typhoon intensity. Though the number of tropical storms was below average, the ratio between tropical storms and typhoons was 66% greater than normal. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) monitored three additional cyclones of at least tropical storm intensity that were not monitored by the JMA.


2003 Pacific typhoon season, Season summary
The season began with the formation of Tropical Storm Yanyan on January 15. After its dissipation five days later, no tropical cyclones of at least tropical storm intensity developed over the next two months. This period of inactivity ended with the formation of Typhoon Kujira in mid-April; Kujira was one of the longest lived Pacific storms on record and was the first typhoon with 1-minute sustained winds of at least 240 km/h (150 mph) in April since Typhoon Isa in 1997.


2003 Pacific typhoon season, Season summary
Tropical activity was enhanced from May to June, and during this period the JMA monitored four tropical storms, while the PAGASA monitored a fifth storm off the eastern Philippines. Three of the four tropical storms monitored by the JMA approached or hit Japan, including Typhoon Soudelor, which brought heavy rainfall and wind across the Ryukyu Islands and the Korean Peninsula.


2003 Pacific typhoon season, Season summary
Tropical activity once again declined towards the second half of June and first half of July. The second half of July, however, featured the development of typhoons Imbudo and Koni, which both tracked westward across the Philippines before striking areas near Saipan and other regions of southeastern China. Imbudo caused the deaths of 78 people and US$383 million in damage. August was a highly active month for tropical cyclogenesis, with a total of six tropical storms monitored by the JMA, JTWC, and PAGASA. This included typhoons Krovanh and Dujuan, which also struck southeastern China. Typhoon Etau earlier in the month made landfall in Japan, resulting in 17 deaths.


2003 Pacific typhoon season, Season summary
Activity was somewhat below average in September, with only one tropical cyclone making landfall, Maemi. However, Maemi was the strongest tropical cyclone of the season and was the costliest with roughly US$4.8 billion in damage, mostly in South Korea. Tropical cyclogenesis and activity continued to decline after August, with October featuring only three tropical storms. However, two, Ketsana and Parma, reached typhoon intensity; both stayed away from land. November featured less storms but was climatologically average, with two typhoons developing. The second typhoon, Lupit, devastated portions of Yap State, resulting in approximately $1.7 million in damage. In December, the JTWC and PAGASA monitored a sole tropical system east of the Philippines, though the JMA did not monitor or classify any tropical cyclones during the month.


2003 Pacific typhoon season, Systems, Tropical Storm Yanyan
On January 11, the JTWC began monitoring the disturbance that would eventually develop into Yanyan near the International Date Line. As the system tracked westward, it gradually moved into a more favorable environment for tropical cyclogenesis. On January 14, surface observations indicated that the low-pressure area had developed a closed, low-level circulation center indicative of a tropical cyclone, satellite imagery remained inconclusive. Nonetheless, the JMA classified the pressure area as a tropical depression west of the Marshall Islands at 0600 UTC on January 15.


2003 Pacific typhoon season, Systems, Tropical Storm Yanyan
The JTWC would follow suit by classifying the storm as such at 1800 UTC later that day. At the time, the depression was tracking west-northwest under the influence of a subtropical ridge to the north. Over the next day the system waned in convective activity before resuming its previous track and accelerating. At 0000 UTC on January 17, the JTWC upgraded the system to tropical storm intensity, though the storm remained nameless as the JMA continued to classify it as a tropical depression.


2003 Pacific typhoon season, Systems, Tropical Storm Yanyan
Throughout January 17 the tropical storm would again oscillate in strength, resulting in a brief downgrade by the JTWC to tropical depression intensity. However, an increase in deep convection resulted in its reclassification as a tropical storm at 1800 UTC that day, followed by the JMA upgrading the system to tropical storm intensity at 1200 UTC on January 18. As such, the storm received the name Yanyan. At roughly the same time, the tropical cyclone began to stall east of the Mariana Islands and curve sharply northeastward.


2003 Pacific typhoon season, Systems, Tropical Storm Yanyan
Whilst the JTWC indicated that Yanyan peaked in strength late on January 18 with 1-minute sustained winds of 60 km/h (37 mph), the JMA considered the system to have maintained the same intensity throughout its stint as a tropical storm. Steered by the same nearby subtropical ridge, Yanyan would continue to track towards the northeast into a less favorable tropical cyclone environment. The JMA downgraded Yanyan to tropical depression at 1200 UTC on January 20 before the storm transitioned into an extratropical cyclone as its low-level circulation center decoupled from the primary mass of convection due to strong wind shear. At 0000 UTC, both the JTWC and JMA discontinued the monitoring of Yanyan.


2003 Pacific typhoon season, Systems, Typhoon Kujira (Amang)
Kujira developed from a broad area of disturbed weather as a tropical depression on April 9 well removed from any landmasses. Shortly after development, Kujira quickly intensified in its early stages, and was upgraded to a tropical storm just two days after cyclogenesis. Strengthening slowed afterwards, though the storm attained typhoon intensity on April 14. Intensification continued and late on April 15, Kujira reached its peak intensity with winds of 165 km/h (105 mph) and a minimum barometric pressure of 930 mbar (hPa; 27.46 inHg).


2003 Pacific typhoon season, Systems, Typhoon Kujira (Amang)
Following peak intensity, Kujira would begin to track northwest and oscillate in strength, cresting an additional two times in intensity. On April 21, the typhoon was downgraded to tropical storm intensity and began to track erratically for several days east of Taiwan. However, on April 24, Kujira would resume a northward track and begin to weaken, and on April 24 was downgraded to tropical depression strength as it made landfall on Kyushu. Following landfall, Kujira transitioned into an extratropical cyclone on April 25, which persisted until crossing the International Dateline towards the end of April 2003.


2003 Pacific typhoon season, Systems, Typhoon Kujira (Amang)
Shortly after developing, Kujira caused two fatalities in Pohnpei in addition to minor agricultural and infrastructural damage; similar effects were felt in Guam. Several days later, the typhoon prompted cyclone warnings and other precautionary measures in the Philippines after forecasts indicated the potential for strong winds and rain. However, ultimately any effects in the archipelago associated with Kujira remained minimal. The typhoon also prompted warning products in Taiwan, making it the first April typhoon since 1978 to cause such a feat. Unlike in the Philippines, however, Kujira would bring significant rainfall to Taiwan.


2003 Pacific typhoon season, Systems, Typhoon Kujira (Amang)
Effects from the typhoon were most significant in Japan, particularly in the Ryukyu Islands. Strong winds, rain, and waves caused US$230,000 (¥27.8 million) in agricultural damage on Ishigaki Island. One person was killed due to injuries resulting from the waves. In Kyushu, heavy rainfall, peaking at 196 mm (7.7 in) in Ōita Prefecture, was reported. Overall, despite its distance away from land and weak intensity at the time of its sole landfall, Kujira resulted in three fatalities.


2003 Pacific typhoon season, Systems, Tropical Depression 03W (Batibot)
An area of convection formed on May 16 to the southwest of Palau, located within an area of weak wind shear. The next day, the JMA and the JTWC both classified the system as a tropical depression. The convection was disorganized in association with multiple circulation centers, although it gradually organized. Moving westward initially, the depression turned more to the north into an area of increasing wind shear. On May 19, the JTWC upgraded the system to Tropical Storm 03W, and on the same day, PAGASA classified it as Tropical Depression Batibot. Soon after, the convection decreased from the center, and by May 20, all warning agencies had discontinued advisories.


2003 Pacific typhoon season, Systems, Typhoon Chan-hom
Midday on May 18, the JTWC began to monitor an area of persistent disturbed weather associated with a broad low-pressure area southwest of Chuuk. Within highly conductive conditions, the disturbance quickly organized and became classified as a tropical depression at 0000 UTC the following day. In its initial stages, the depression tracked slowly northeastwards. However, a shortwave trough forced a weakness in a nearby ridge, allowing for the storm to take a more streamlined, northward path. At 1200 UTC on May 20, the JMA upgraded the depression to Tropical Storm Chan-hom.


2003 Pacific typhoon season, Systems, Typhoon Chan-hom
Following the system's naming, Chan-hom temporarily meandered towards the northwest before resuming its northeasterly track. The next day, the storm began to develop an eye; this was reflected with an upgrade by the JMA to typhoon status at 0600 UTC on May 23. Gradual intensification followed, and at 1800 UTC that day Chan-hom reached its peak intensity with maximum sustained winds of 155 km/h (100 mph) and a minimum pressure of 940 mbar (hPa; 27.76 inHg).


2003 Pacific typhoon season, Systems, Typhoon Chan-hom
Following peak intensity, Chan-hom began to intake dry air beginning on May 25. At roughly the same time, the typhoon began to weaken and accelerate towards the northeast. Conditions continued to worsen as the storm moved further north, and as the cyclone passed east of Minamitorishima, it was downgraded to tropical storm classification. By this time, Chan-hom had lost much of its convection due to wind shear. Early on May 27, Chan-hom had fully transitioned into an extratropical cyclone, and these remnants continued to track towards the northeast. These extratropical remnants dissipated south of the Aleutian Islands the following day.


2003 Pacific typhoon season, Systems, Typhoon Chan-hom
Early in the typhoon's existence, Chan-hom posed a potential threat to Guam, but remained well east of the island. However, after passing to the northeast, winds from the typhoon fanned volcanic ash from the recently erupting Anatahan volcano towards the island, prompting precautionary measures in Guam. Ashfalls were reported on the island, forcing the cancellation of several flights. As a tropical storm, Chan-hom caused some damage to homes and crops on Chuuk, mostly due to heavy rains brought forth by the storm. Offshore, a 1,040 ton fishing vessel, the Nien Feioch, sank during the storm. The ship was valued at $16 million.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Linfa (Chedeng)
Tropical Storm Linfa developed as a tropical depression just off the western coast of Luzon on May 25. The disturbance quickly intensified to reach tropical storm intensity a few hours after cyclogenesis. However, intensification leveled off as Linfa executed a small clockwise loop before a subsequent landfall on Luzon on May 27. Due to land interaction the storm temporarily weakened and decoupled before reforming in the Philippine Sea. Afterwards Linfa began reintensifying and reached its peak intensity on May 29 with maximum sustained winds of 100 km/h (65 mph) and a barometric pressure of 980 mbar (hPa; 28.94 inHg). Following its peak the tropical storm began to deteriorate and transitioned into an extratropical cyclone on May 30; these extratropical remnants continued to track northward through Japan before dissipating in the Sea of Okhotsk on June 4.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Linfa (Chedeng)
The erratic and slow movement of Linfa off the western Philippines was the catalyst for extreme rainfall and flooding, killing 41 persons in the archipelago. Precipitation peaked at 723 mm (28.5 in) near Dagupan. Rising floodwaters resulted in the temporary shutdown of government offices and numerous mudslides. In addition, strong winds caused widespread power outages. Overall damage from Linfa in the Philippines amounted to ₱192.3 million (US$3.65 million). The floods also displaced 8,367 people in 1,686 families and destroyed 178 homes. Linfa and its extratropical remnants later brought torrential rainfall and widespread flooding to Japan, particularly in southwestern regions.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Linfa (Chedeng)
Rainfall there peaked at 727 mm (28.62 in). Flood damage was worst in Kōchi and Tokushima Prefectures, where several buildings were destroyed by floodwater. Other locations in Japan experienced considerable agricultural damage as well as numerous landslides. Overall, Linfa caused roughly $28.2 million in damage, much of which occurred in Japan, though the entirety of deaths associated with the cyclone took place in the Philippines.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Nangka (Dodong)
In late May, an area of disturbed weather began to persist in the South China Sea. The JTWC began to monitor the storm cluster on May 29. The following day, the JMA reclassified the system as a tropical depression; initially the system remained highly disorganized due to the lack of deep convection. Persistent moderate wind shear and dry air prevented the cyclone from strengthening significantly in the storm's early stages. These conditions abated as the depression tracked northeast, and at 0000 UTC on June 1, the JMA upgraded the system to Tropical Storm Nangka. Throughout the course of the day, Nangka continued to strengthen as it accelerated northeast, and peaked in strength with a barometric pressure of 985 mbar (hPa; 29.09 inHg) and maximum sustained winds of 95 km/h (60 mph), making it a severe tropical storm.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Nangka (Dodong)
However, upon moving through the Bashi Channel, conditions began to deteriorate due to increased wind shear, weakening the system and resulting in its downgrade to tropical depression status by the JMA at 1200 UTC on June 3. Nangka continued to become increasingly disorganized as it moved further north, and late that day, the depression transitioned to an extratropical cyclone. The resulting remnants continued to track well east of Japan before dissipating on June 7. Due to its track away from landmasses, damage remained minimal; however, as Nangka passed to the south and east of Japan, the storm brought light rainfall to the country, peaking at 81 mm (3.2 in) in Minamidaitō, Okinawa.


2003 Pacific typhoon season, Systems, Typhoon Soudelor (Egay)
A tropical disturbance persisted in the monsoon trough northwest of Pohnpei on June 7, and moved westward without development due to wind shear. On June 11, the shear decreased enough to allow the convection to organize, and the next day the JMA classified it as a tropical depression northeast of Palau. On June 13, the JMA upgraded it to Tropical Storm Soudelor to the east of the Philippines, and PAGASA gave it the local name "Egay".


2003 Pacific typhoon season, Systems, Typhoon Soudelor (Egay)
Soudelor moved to the northwest and later to the north, parallel to the eastern Philippines, and on June 17, the JMA upgraded it to typhoon status. The storm rapidly intensified to the east of Taiwan as it developed a well-defined eye, and while doing so passed over the Japanese island of Iriomote-jima at around 2030 UTC on June 17. At 0600 UTC on June 18, the JTWC estimated peak 1 minute winds of 215 km/h (135 mph), while the JMA estimated peak 10 minute winds of 150 km/h (90 mph). Increased shear weakened the typhoon to tropical storm strengthen on June 19, and later that day the JMA declared the storm as extratropical near the Oki Islands. The extratropical remnants of Soudelor continued to the northeast, crossing northern Japan on June 20 and dissipating on June 24.


2003 Pacific typhoon season, Systems, Typhoon Soudelor (Egay)
While offshore the Philippines, Soudelor dropped heavy rainfall that caused flooding and left thousands homeless. The storm caused ₱131 million (PHP, $2.46 million USD) in damage and 12 deaths. On the Japanese island of Iriomote-jima, where wind gusts reached 204 km/h (127 mph). It also affected Taiwan, where floods covered highways and caused mudslides. In Japan, the storm caused widespread power outages, although damage was minimal, and there were 21 injuries. In South Korea, there was $12.1 million in damage and two deaths.


2003 Pacific typhoon season, Systems, Typhoon Imbudo (Harurot)
On July 15, the JMA estimated that a tropical depression formed, and the next day the JTWC initiated advisories on Tropical Depression 09W about 665 km (415 mi) east of Yap. A subtropical ridge near Okinawa steered the nascent depression to the west-northwest for much of its duration. With warm waters and favorable upper-level conditions, the depression quickly organized, first to Tropical Storm Imbudo on July 17, and to typhoon status two days later, when PAGASA begin issuing advisories on Typhoon Harurot. Around that time, Imbudo was rapidly intensifying, developing a well-defined eye.


2003 Pacific typhoon season, Systems, Typhoon Imbudo (Harurot)
At 1200 UTC on July 20, the JMA estimated peak 10 minute sustained winds of 165 km/h (105 mph), and the same time, the JTWC estimated 1 minute sustained winds of 240 km/h (150 mph), making it a super typhoon. Imbudo maintained peak winds for about 12 hours, before undergoing an eyewall replacement cycle. At 0300 UTC on July 22, Imbudo struck northern Luzon, with 1 minute winds estimated at 205 km/h (125 mph) by the JTWC. It weakened over land, but re-intensified in the South China Sea, striking southern China near Yangjiang, Guangdong on July 24. Imbudo rapidly weakened, dissipating on July 25.


2003 Pacific typhoon season, Systems, Typhoon Imbudo (Harurot)
In the Philippines, officials evacuated over 14,000 people. Imbudo was the strongest typhoon to strike since Typhoon Zeb five years prior, The typhoon left widespread areas flooded for several days. Damage was heaviest in the Cagayan Valley, where over 80,000 people were displaced by the storm. In Isabela, high winds wrecked most of the banana crop and severely damaged other crops. Throughout the Philippines, Imbudo damaged or destroyed 62,314 houses, causing P4.7 billion (2003 PHP, $86 million 2003 USD) in damage. There were 64 deaths in the country.


2003 Pacific typhoon season, Systems, Typhoon Imbudo (Harurot)
In southern China in Yangjiang, more than 30,000 people evacuated ahead of the storm, and more than half of the trees in the city fell due to strong winds. High winds killed a man in Hong Kong after knocking him off a platform. Throughout Guangdong, Imbudo destroyed 595,000 houses and caused eight deaths. Heavy rains spread across southern China, peaking at 343 mm (13.5 in) at Hepu County in Guangxi province. There, 12 people died from the storm. Overall damage in China was about ¥4.45 billion (CNY, $297 million USD).


2003 Pacific typhoon season, Systems, Severe Tropical Storm Koni (Gilas)
Koni originated from a tropical depression situated within the monsoon trough to the east of the Philippines on July 15. Tracking westward, intensification was slow and the system remained a tropical depression as it moved across the central Philippines on July 17. Upon moving into the South China Sea, conditions allowed for quicker strengthening, and the cyclone reached tropical storm status on July 18 before reaching its peak intensity with maximum sustained winds of 110 km/h (70 mph), making it a severe tropical storm.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Koni (Gilas)
However, atmospheric conditions began to deteriorate as Koni made landfall on Hainan on July 21, weakening the system. The tropical storm continued to weaken as it moved over the Gulf of Tonkin prior to a final landfall near Hanoi, Vietnam the following day. Tracking inland, the combination of land interaction and wind shear caused Koni to dissipate over Laos on July 23.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Koni (Gilas)
Shortly after development, Koni tracked through the Philippines, killing two people. After moving into the South China Sea, turbulence produced by the storm resulted in an aviation incident involving a commercial airliner off the western Philippines. Three of the plane's occupants received minor injuries. In Hainan, Koni caused heavy rainfall, peaking at 189 mm (7.44 in) at a station on Wuzhi Mountain. The rains resulted in the collapse of 1,400 homes and an estimated CN¥140.27 million (US$16.9 million) in direct economic losses. Effects were worst in Vietnam, where three people were killed. Widespread power outages occurred, and strong winds resulted in agricultural and infrastructural damage, particularly in Vietnam's northern provinces.


2003 Pacific typhoon season, Systems, Tropical Storm Morakot (Juaning)
Morakot spawned from an area of disturbed weather in the Philippine Sea on July 31. Tracking northwest, favorable conditions allowed for the intensification of the system to tropical storm strength on August 2. Morakot reached peak intensity later that day with winds of 85 km/h (50 mph) and a minimum barometric pressure of 992 mbar (hPa; 28.29 inHg).


2003 Pacific typhoon season, Systems, Tropical Storm Morakot (Juaning)
This intensity was held for several hours until less conducive atmospheric conditions slightly weakened the system; this was followed by Morakot making landfall on southern Taiwan on August 3. Subsequently, the storm weakened and moved into the Taiwan Strait before making its final landfall near Quanzhou, China the next day. The storm quickly weakened over the Chinese mainland, and dissipated entirely several hours after landfall.


2003 Pacific typhoon season, Systems, Tropical Storm Morakot (Juaning)
In Taiwan, where Morakot first made landfall, heavy rainfall resulted in flooding. Commercial flights, schools, and rail service in some areas was cancelled in advance of the storm. Precipitation there peaked at 653 mm (25.71 in) over a period of nearly two days in Taitung County. Crop damage also resulted from the rainfall, and was estimated at over NT$70 million (US$2 million). In China, record rainfall was reported. The worst impacted city was Quanzhou, where losses due to Morakot reached CN¥240 million (US$29 million) and one death was reported. Power outages were also widespread across southeastern China. Due to preexisting drought conditions, 703 cloud seeding operations took place in order to artificially generate added rainfall; such operations resulted in moderate precipitation over the targeted area. Overall, Morakot caused roughly $31 million in damage and three deaths.


2003 Pacific typhoon season, Systems, Typhoon Etau (Kabayan)
A tropical depression developed on August 2 southeast of Guam, and gradually intensified while moving to the northwest, becoming a tropical storm on August 3 and a typhoon a day later. Etau formed an eye and became a large storm by the time it approached Okinawa on August 7. The typhoon attained peak winds of 155 km/h (100 mph) before weakening slightly while turning to the northeast. Etau made landfall on the Japanese island of Shikoku on August 8, and later moved across portions of Honshu and Hokkaido. After weakening to tropical storm status, the cyclone became extratropical on August 9 and dissipated three days later.


2003 Pacific typhoon season, Systems, Typhoon Etau (Kabayan)
While passing northeast of the Philippines, the typhoon caused light damage in the archipelago. The eye crossed over Okinawa, where Etau left 166,800 people without power and caused 10 injuries. Near where Etau first struck Japan, Muroto reported a peak wind gust of 166 km/h (103 mph), at the time the third strongest on record there. The typhoon also dropped torrential rainfall peaking at 683 mm (26.9 in). The combination of winds and rainfall caused landslides, particularly on Hokkaido. Nationwide, Etau killed 20 people, destroyed 708 houses, and caused ¥35.1 billion (JPY, $294.8 million USD) in damage.


2003 Pacific typhoon season, Systems, Typhoon Krovanh (Niña)
Krovanh originated from a tropical disturbance within the monsoon trough east of Chuuk State on August 13. Despite rather favorable conditions, the initial tropical depression did not intensify significantly and degenerated into a remnant low on August 18. However, these remnants were able to reorganize and the system was reclassified as a tropical cyclone a day later. Intensification was rather rapid upon the storm's reformation – the depression reached tropical storm status on August 20 and then typhoon intensity two days later. Shortly after, Krovanh made landfall on Luzon at peak intensity with winds of 120 km/h (75 mph).


2003 Pacific typhoon season, Systems, Typhoon Krovanh (Niña)
The typhoon emerged into the South China Sea as a much weaker tropical storm, though it was able to restrengthen over warm waters. Once again at typhoon intensity, Krovanh clipped Hainan before moving over the Leizhou Peninsula on its way to a final landfall near Cẩm Phả, Vietnam on August 25. Quick weakening due to land interaction occurred as Krovanh moved across northern Vietnam, where the storm met its demise the following day.


2003 Pacific typhoon season, Systems, Typhoon Krovanh (Niña)
Krovanh first struck the Philippines, resulting in heavy rainfall and displacing approximately 1,000 families. The flooding caused severe damage and killed one person. Krovanh's effects were much more severe in China. In Hong Kong, eleven people were injured and isolated flooding occurred as a result of the typhoon's outer rainbands. However, Guangdong Province, Hainan Province, and Guangxi were the Chinese regions most extensively impacted. The typhoon brought record wind gusts into Guangxi. In those three regions combined, 13,000 homes were estimated to have collapsed and a large swath of farmland was damaged.


2003 Pacific typhoon season, Systems, Typhoon Krovanh (Niña)
Two people were killed in China and economic losses approximated to ¥2.1 billion (US$253 million). Due to its positioning and track, of all areas in Vietnam only the country's more northern regions were impacted by Krovanh. Flash flooding occurred in earnest in those regions, and 1,000 homes were flattened. One person was killed and five others were injured in Vietnam. Overall, the typhoon was responsible for the deaths of four persons.


2003 Pacific typhoon season, Systems, Tropical Storm Vamco (Manang)
The monsoon trough spawned several tropical disturbances in the middle of August, one of which became Tropical Depression Lakay near the Philippines. On August 18, an area of convection persisted on the southern side of a circulation, developing into a tropical depression east of Luzon. It moved quickly northward and later to the northwest in an area generally unfavorable for strengthening, such as the presence of wind shear and land interaction. On August 19, the JMA upgraded the depression to Tropical Storm Vamco to the east of Taiwan. Later that day, the circulation passed just 55 km (35 mi) north of Taipei, although the convection was exposed that time. On August 20, the JMA assessed Vamco as dissipating in the Taiwan Strait, although the JTWC continued advisories until the storm moved ashore in southeastern China.


2003 Pacific typhoon season, Systems, Tropical Storm Vamco (Manang)
Rainfall in Taiwan reached 69 mm (2.7 in) in Ilan County. On the island, the storm left several hundred houses without power due to a lightning strike. On mainland China, rainfall peaked at 101 mm (4.0 in) in Wenzhou, Zhejiang, which were largely beneficial in easing drought conditions, while winds gusted to 100 km/h (62 mph). The storm damaged or destroyed 5,880 houses and flooded 1,287 ha (3,180 acres) of paddy fields, causing ¥38.6 million (CNY, $4.7 million USD) in damage.


2003 Pacific typhoon season, Systems, Typhoon Dujuan (Onyok)
On August 27, a tropical depression developed about 520 km (325 mi) northwest of Guam, which initially drifted to the southwest before turning to the northwest. On August 29, the JMA upgraded it to Tropical Storm Dujuan, and that day PAGASA began issuing advisories on Tropical Storm Onyok. The storm quickly intensified into a typhoon, after developing an eye in the center. On September 1, the JMA estimated Dujuan attained peak 10 minute winds of 150 km/h (90 mph), and the JTWC assessed peak 1–minute winds of 230 km/h (145 mph).


2003 Pacific typhoon season, Systems, Typhoon Dujuan (Onyok)
While near peak intensity, the center of Dujuan passed about 45 km (30 mi) south of the southern tip of Taiwan. The typhoon weakened steadily and was a severe tropical storm by the time it made landfall on September 2 just east of Hong Kong. The JTWC estimated landfall winds of 185 km/h (115 mph), making it the strongest typhoon to strike the Pearl River Delta since Typhoon Hope in 1979. Dujuan rapidly weakened while continuing westward through China, dissipating on September 3 over Guangxi.


2003 Pacific typhoon season, Systems, Typhoon Dujuan (Onyok)
In the Philippines, Dujuan interacted with the monsoon to produce heavy rainfall, killing one person. While in the vicinity, Dujuan produced gusts of 100 km/h (62 mph) on Yonaguni, a Japanese subdivision of Okinawa. Heavy rainfall in Taiwan reached 628 mm (24.7 in) in Pingtung County, and winds peaked at 176 km/h (109 mph) on Orchid Island before the anemometer was destroyed. The caused about NT$200 (NWD, $115 million USD) in crop damage, and killed three people. Damage was minor in Hong Kong, and four fishermen were missing and presumed drowned after their boat sank.


2003 Pacific typhoon season, Systems, Typhoon Dujuan (Onyok)
On the Chinese mainland, strong winds left 90% of the city of Shenzen without power, and killed 16 construction workers due to a half-finished building collapsing. Across Guangdong, the typhoon damaged crops and destroyed 54,000 homes were destroyed. Overall damage in China was estimated at ¥2.3 billion (CNY, $277 million USD), and across Guangdong, the typhoon killed 40 people.


2003 Pacific typhoon season, Systems, Typhoon Maemi (Pogi)
Typhoon Maemi formed on September 4 from the monsoon trough in the western Pacific Ocean. It slowly intensified into a tropical storm while moving northwestward, and Maemi became a typhoon on September 8. That day, it quickly intensified due to favorable conditions, developing a well-defined eye and reaching peak maximum sustained winds of 195 km/h (120 mph). While near peak intensity, Maemi was decelerating and began turning to the north-northeast.


2003 Pacific typhoon season, Systems, Typhoon Maemi (Pogi)
The eyewall soon after passed over the Japanese island of Miyako-jima on September 10, producing the fourth lowest pressure on record in Japan after a pressure of 912 mbar (26.9 inHg) was recorded. With warm waters, Maemi was able to maintain much of its intensity before it made landfall just west of Busan, South Korea on September 12.


2003 Pacific typhoon season, Systems, Typhoon Maemi (Pogi)
On Jeju Island, Maemi produced a peak wind gust of 216 km/h (134 mph) and a minimum pressure of 950 mbar (28 inHg), both setting records for the country, and making it the most powerful typhoon to strike South Korea since record-keeping began in the country in 1904. The typhoon became extratropical in the Sea of Japan the next day, although the remnants persisted for several more days, bringing strong winds to northern Japan.


2003 Pacific typhoon season, Systems, Typhoon Maemi (Pogi)
The typhoon first affected the Ryukyu Islands of Japan. On Miyako-jima, strong winds damaged 104 buildings, and 95% of residents lost power. Maemi dropped heavy rainfall there, including rates of 58.5 mm (2.30 in) in an hour, and 402.5 mm (15.85 in) in 24 hours, the latter setting a record. One person died on Miyako-jima after being struck by flying glass. Elsewhere in Japan, the storm caused flights to be canceled, while rainfall-induced landslides blocked roads. There were two other deaths in Japan, and damage totaled ¥11.3 billion (JPY, $96 million USD).


2003 Pacific typhoon season, Systems, Typhoon Maemi (Pogi)
Damage was heaviest in South Korea, notably where it moved ashore. Winds in Busan near the landfall location reached 154 km/h (96 mph), the second-highest on record. There, the port sustained heavy damage, causing disruptions to exports in the months following the storm. Nationwide, the high winds destroyed about 5,000 houses and damaged 13,000 homes and businesses, leaving 25,000 people homeless. About 1.47 million lost power, and widespread crop damage occurred, resulting in the worst rice crop in 23 years. Across South Korea, Maemi killed 117 people, and overall damage totaled ₩5.52 trillion won ($4.8 billion USD).


2003 Pacific typhoon season, Systems, Typhoon Choi-wan (Roskas)
In the middle of September, the monsoon trough spawned a rapidly organizing disturbance east-northeast of Luzon, with weak wind shear and favorable conditions. On September 16, the JMA classified it as a tropical depression, and the JTWC initiated advisories the next day. The system moved to the northwest due to the subtropical ridge to the northeast and later to the north. On September 18, the JMA upgraded the depression to Tropical Storm Choi-wan, the same day that PAGASA classified it as Tropical Storm Roskas (the only time this name was used, as it was retired the following year).


2003 Pacific typhoon season, Systems, Typhoon Choi-wan (Roskas)
An eastward-moving trough turned the storm to the northeast, bringing the track over Okinawa and Amami Ōshima on September 19. Choi-wan continued gradually intensifying, becoming a typhoon on September 20 to the southeast of Japan. That day, the JMA estimated peak winds of 130 km/h (80 mph), and the JTWC estimated peak 1 minute winds of 185 km/h (115 mph) on September 21, after Choi-wan developed a well-defined eye. The typhoon weakened due to increasing wind shear, deteriorating to severe tropical storm status on September 22 before JMA declared it extratropical on September 23. The remnants of Choi-wan continued to the northeast, exited the basin on September 24, and eventually struck southern Alaska on September 25.


2003 Pacific typhoon season, Systems, Typhoon Choi-wan (Roskas)
Wind gusts in Okinawa reached 115 km/h (72 mph), while on the volcanic island of Hachijō-jima, gusts reached 214 km/h (133 mph). On the Japanese mainland, winds gusted to 126 km/h (78 mph) at Chōshi, Chiba. Choi-wan dropped heavy rainfall while near Japan, peaking at 316 mm (12.4 in) on Miyake-jima. In Okinawa, Choi-wan flooded a boat, forcing its occupants to be rescued by the Coast Guard. Also on the island, heavy rainfall caused landslides and flooded houses. In Amami Ōshima, the storm left 10,810 people without power. On Hachijō, wind gusts of 214 km/h (133 mph) damaged about 200 houses. Nationwide, Choi-wan destroyed 191 homes, injured 9 people, and left about ¥300 million (JPY, $2.5 million USD).


2003 Pacific typhoon season, Systems, Typhoon Koppu (Sikat)
Towards the end of September, the monsoon trough spawned a tropical disturbance east-northeast of Yap, which became a tropical depression on September 24. There were initially several circulations, with a tropical upper tropospheric trough to the northeast increasing outflow. After slowing and turning to the northeast, the depression intensified into Tropical Storm Koppu on September 26. After the storm developed a large eye feature, the JTWC upgraded it to typhoon status on September 27, although the JMA did not follow suit until the following day while near Chichi-jima.


2003 Pacific typhoon season, Systems, Typhoon Koppu (Sikat)
Also that day, Koppu passed 95 km (60 mi) west of Iwo Jima, and the JMA estimated peak 10 minute winds of 130 km/h (80 mph). The JTWC estimated peak 1 minute winds of 165 km/h (105 mph), before an approaching trough caused the typhoon to accelerate northeastward. The convection diminished near the center, causing Koppu to become extratropical on September 30. The remnants continued generally northeastward through the Aleutian Islands, eventually passing south of mainland Alaska on October 7.


2003 Pacific typhoon season, Systems, Typhoon Koppu (Sikat)
On Chichi-jima, Typhoon Koppu produced sustained winds of 102 km/h (63 mph), with gusts to 200 km/h (124 mph), which was the third strongest on record for the station. Rainfall there reached 183 mm (7.2 in). Wind gusts on Iwo Jima peaked at 109 km/h (68 mph).


2003 Pacific typhoon season, Systems, Tropical Depression 18W
On October 6, the JTWC classified Tropical Depression 18W early in the month off the west coast of Luzon. With weak steering currents, the system moved slowly southwestward before looping to the northwest. On October 10, the depression dissipated just off the coast of southern China.


2003 Pacific typhoon season, Systems, Tropical Depression 19W
Following the demise of 18W, the JTWC monitored Tropical Depression 19W, which developed on October 12 after an extratropical storm produced an area of convection. Described as a subtropical low, the depression moved generally northeastward toward Japan due to an approaching cold front. The depression moved through Kyushu and Honshu before dissipating on October 13.


2003 Pacific typhoon season, Systems, Tropical Depression 19W
The depression dropped 285 mm (11.2 in) of rainfall in Kōchi, while strong winds associated reached 217 km/h (135 mph) through a storm-produced downburst. The winds knocked over two cranes, killing two people, and left about 9,000 homes without power. The depression also killed two people due to drownings.


2003 Pacific typhoon season, Systems, Typhoon Ketsana (Tisoy)
In the middle of October, an area of convection persisted along the monsoon trough between Luzon and Guam, developing into a tropical depression on October 17. The same monsoon trough later spawned Typhoon Parma to the east. For several days, the system remained disorganized while drifting to the west-northwest due to weak steering currents south of the subtropical ridge. On October 19, the JMA upgraded the depression to Tropical Storm Ketsana, and by that time the storm had begun drifting to the northeast.


2003 Pacific typhoon season, Systems, Typhoon Ketsana (Tisoy)
With favorable outflow, Ketsana quickly intensified into a typhoon on October 20 after developing an eye, and two days later, the JMA estimated peak winds of 165 km/h (105 mph). The JTWC estimated peak 1 minute winds of 230 km/h (145 mph) around the time the well-defined eye had expanded to 37 km (23 mi). Subsequently, the typhoon accelerated northeastward into the westerlies and began weakening due to increasing wind shear and dry air. On October 26, Ketsana became extratropical to the east of Japan and dissipated the next day. The passage of the typhoon caused surface chlorophyll a concentration in the ocean to increase 30-fold.


2003 Pacific typhoon season, Systems, Typhoon Parma
The same monsoon trough that spawned Typhoon Koppu also produced an area of convection to the north-northeast of Guam, becoming a tropical depression on October 19. The system moved northwestward and later turned to the northeast around the subtropical ridge. With low wind shear and favorable outflow, the convection became better organized, and the JMA upgraded it to Tropical Storm Parma on October 21. After an eye began to form, Parma was upgraded to typhoon status the next day. An approaching trough caused Parma to accelerate northeastward while also increasing outflow.


2003 Pacific typhoon season, Systems, Typhoon Parma
On October 24, the JMA estimated peak winds of 175 km/h (110 mph) while the JTWC estimated winds of 240 km/h (150 mph), an unusually high intensity for 30° N. Subsequently, Parma rounded the subtropical ridge and began moving to the east-southeast, beginning a nearly week-long loop. The cold front had passed to the north and failed to bring the typhoon northeastward.


2003 Pacific typhoon season, Systems, Typhoon Parma
Increasing wind shear weakened the convection, and Parma deteriorated into a severe tropical storm on October 26. The next day, it began moving westward while passing about 345 km (215 mi) north of Wake Island. A large eye of 110 km (70 mi) in diameter developed, and on October 28, the JMA re-upgraded Parma to typhoon status. The next day, the typhoon turned to the northeast due to another approaching trough.


2003 Pacific typhoon season, Systems, Typhoon Parma
With decreasing wind shear and warmer waters, Parma re-intensified significantly on October 29, reaching a secondary peak of 165 km/h (105 mph) according to JMA, and 215 km/h (135 mph) according to JTWC. The storm moved very closely along the track it took several days prior. Increasing wind shear on October 30 caused rapid weakening, resulting in the eye dissipating. By the next day, the center was exposed, and Parma became extratropical, later exiting the basin on November 1. The remnants weakened, later turning to the southeast and dissipating on November 11 southwest of California.


2003 Pacific typhoon season, Systems, Tropical Depression 23W
On October 21, a monsoon trough spawned a tropical depression in the Gulf of Thailand, which moved northwestward and crossed into the Indian Ocean, dropping heavy rainfall in Thailand.


2003 Pacific typhoon season, Systems, Tropical Depression 22W (Ursula)
On October 22, a tropical depression developed in the South China Sea, classified by PAGASA as Ursula. The system moved eastward and crossed Palawan before dissipating on October 24. In the Philippines, the depression killed one person and caused minor damage.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Melor (Viring)
Late in October, an area of convection persisted northwest of Palau and quickly organized into a tropical depression on October 29. Moving west-northwestward toward the Philippines due to a ridge to the east, the depression intensified into Tropical Storm Melor on October 30. With minimal wind shear, the storm strengthened further and developed a large eye. The JTWC upgraded Melor to typhoon status on October 31, estimating peak 1 minute winds of 140 km/h (85 mph), although the JMA estimated the storm only attained peak 10 minute winds of 95 km/h (60 mph).


2003 Pacific typhoon season, Systems, Severe Tropical Storm Melor (Viring)
Early on November 1, Melor made landfall on northeastern Luzon in the Philippines, south of Palanan. The storm weakened over land and emerged into the South China Sea. By that time, it was moving northward along the periphery of the ridge to the east. On November 2, Melor turned to the northeast, passing just east of Taiwan. The next day, it weakened to tropical depression status, and after meandering offshore eastern Taiwan, Melor continued northeastward. It became extratropical on November 5 and dissipated the next day near southern Japan.


2003 Pacific typhoon season, Systems, Severe Tropical Storm Melor (Viring)
In the Philippines, Melor dropped about 150 mm (6 in) of rainfall, which flooded the Cagayan River and killed four people. In Taiwan, rainfall reached 554 mm (21.8 in) in Pingtung County. On the Japanese island of Hateruma, rainfall totaled 197 mm (7.8 in), which broke the hourly and daily record for the station in November.


2003 Pacific typhoon season, Systems, Typhoon Nepartak (Weng)
A tropical depression developed near Yap on November 11. The system intensified gradually as it tracked quickly westward toward the Philippines. An anticyclone aloft allowed for strengthening, and the JMA upgraded the depression to Tropical Storm Nepartak on November 12. Simultaneously, the cyclone entered the area of responsibility of the Philippine Atmospheric, Geophysical and Astronomical Services Administration, which named it Tropical Storm Weng. At around 1600 UTC on November 13, Nepartak made landfall on northern Samar Island in the Philippines before traversing the remainder of the archipelago from east to west.


2003 Pacific typhoon season, Systems, Typhoon Nepartak (Weng)
The cyclone emerged into the South China Sea weakened but quickly re-intensified while continuing to the west-northwest. The JTWC estimated peak winds of 140 km/h (85 mph) on November 16, and later that day, the JMA upgraded the storm to typhoon status, estimating peak 10-minute winds of 120 km/h (75 mph). On November 18, Nepartak passed near southwestern Hainan and weakened, with the convection diminishing from the circulation. By the next day, the system weakened to tropical depression status, and dissipated shortly after moving ashore over Beihai, China.


2003 Pacific typhoon season, Systems, Typhoon Nepartak (Weng)
In the Philippines, Nepartak produced strong winds, heavy rainfall, and rough seas. The storm caused widespread power outages and ferry disruptions. According to the PAGASA in its post-storm report, a total of 13 people lost their lives during the storm. On Hainan, the storm helped end one of the worst summer droughts in almost 65 years, although it also left heavy crop damage, wrecking 64,000 ha (160,000 acres) of fields and killing 400 head of livestock. With about 800 homes destroyed, damage on Hainan amounted to $197 million (2003 USD). Effects were minor in mainland China.


2003 Pacific typhoon season, Systems, Typhoon Lupit (Yoyoy)
Typhoon Lupit formed on November 18 from the monsoon trough to the west of the Marshall Islands. Early in its duration, it moved generally to the west or west-southwest. On November 21, the depression intensified into Tropical Storm Lupit, and two days later, it strengthened into a typhoon, developing an eye. Lupit later began a prolonged movement to the northwest, during which it passed near several islands in Yap State. The typhoon reached peak intensity on November 26, with peak 10–minute sustained winds of 185 km/h (115 mph). It later weakened due to a variety of unfavorable conditions, and after recurving to the northeast, Lupit became extratropical south of Japan on December 2.


2003 Pacific typhoon season, Systems, Typhoon Lupit (Yoyoy)
Typhoon Lupit first affected Pohnpei with gusty winds, and later it damaged or destroyed about 200 homes in Chuuk State. There, high waves flooded roads and homes, while high winds damaged crops. Damage was heaviest in Yap State, mostly in the small Ulithi atoll and Fais Island. On both islands, the typhoon contaminated the water supply and wrecked the crops. Rainfall reached 263 mm (10.35 in) on Ulithi, and gusts reached 158 km/h (98 mph). Throughout the FSM, damage totaled about $1.7 million, although there were no deaths.


2003 Pacific typhoon season, Systems, Typhoon Lupit (Yoyoy)
The damage prompted the FSM government to declare two states as disaster areas, as well as a disaster declaration from the United States federal government. While Lupit was becoming extratropical, it became the first typhoon in December to threaten Japan in 13 years. The storm dropped rainfall that resulted in mudslides and flight cancellations.


2003 Pacific typhoon season, Systems, Tropical Depression 27W (Zigzag)
The final system of the year was a tropical depression that originated out of the monsoon trough on December 24 east of the Philippines. After initially moving to the west, it turned to the south, and the JTWC estimated the depression intensified into a tropical storm. During this time, PAGASA classified it as Tropical Storm Zigzag. The system made landfall in northeastern Mindanao and dissipated on December 27, bringing heavy rainfall.


2003 Pacific typhoon season, Systems, Other systems
On July 9, PAGASA classified a system as Tropical Depression Falcon, off the west coast of the Philippines. The JMA also briefly initiated advisories before dropping them later on July 9. Later in the month, PAGASA briefly issued advisories on Tropical Depression Ineng on July 30 off the east coast of Mindanao. The depression dissipated the next day, causing about P8 million (PHP, $145,000 USD) in damage. The monsoon trough spawned a tropical depression north of Luzon on August 18, with PAGASA naming it Lakay.


2003 Pacific typhoon season, Systems, Other systems
There were several circulations in the region, with Tropical Storm Vamco to the northeast near Taiwan, and the overall system moved generally westward. PAGASA briefly classified Lakay as a tropical storm on August 19 before ending advisories the next day. The system spread rainfall across China, reaching 82.4 mm (3.24 in) in Xiamen, Fujuan.


2003 Pacific typhoon season, Systems, Other systems
On September 5, former Hurricane Jimena crossed the International Date Line into the basin. By that time, the circulation was largely exposed from the convection, and the center quickly dissipated. Later in the month, the monsoon trough spawned a disturbance east of the Philippines that PAGASA classified as Tropical Depression Quiel on September 15. The system moved westward but never intensified, dissipating west of Luzon on September 19. The broad system also spawned Typhoon Choi-wan.


2003 Pacific typhoon season, Systems, Other systems
On October 5, the JMA monitored a tropical depression southeast of Taiwan that later passed near the island, producing heavy rainfall that peaked at 153 mm (6.0 in) in Ilan County. On October 16, the JMA briefly classified a tropical depression to the east of the Marianas Islands. Also in October, the monsoon trough spawned a tropical depression in the Gulf of Thailand, which moved northwestward and crossed into the Indian Ocean, dropping heavy rainfall in Thailand.


2003 Pacific typhoon season, Systems, Other systems
In mid-November, the JMA briefly tracked a weak tropical depression near Wake Island. The agency also briefly tracked a tropical depression off the coast of Vietnam on December 16. It finally dissipated on December 17, with the pressure and winds unknown.


2003 Pacific typhoon season, Storm names
Within the North-western Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names. The Japan Meteorological Agency's RSMC Tokyo — Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of 65 km/h, (40 mph).


2003 Pacific typhoon season, Storm names
While the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N-25°N even if the cyclone has had an international name assigned to it. The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee. Should the list of names for the Philippine region be exhausted then names will be taken from an auxiliary list of which the first ten are published each season. Unused names are marked in gray.


2003 Pacific typhoon season, Storm names, International names
During the season 21 named tropical cyclones developed in the Western Pacific and were named by the Japan Meteorological Agency, when it was determined that they had become tropical storms. These names were contributed to a list of a 140 names submitted by the fourteen members nations and territories of the ESCAP/WMO Typhoon Committee. All of these names were used for the first (and only, in the cases of Yanyan, Imbudo, Koni, and Maemi) time this year.


2003 Pacific typhoon season, Storm names, Philippines
The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. The names not retired from this list will be used again in the 2007 season. Names that were not assigned are marked in gray. The name Gilas that used for Koni was found unidentified by many; It was unexpected that the name Gilas will replace with the name Goring. Gilas, along with Batibot, Lakay, Manang, Niña, Pogi, Roskas, and Sikat were replaced for no reason.


2003 Pacific typhoon season, Storm names, Retirement
The names Imbudo and Maemi were retired by the ESCAP/WMO Typhoon Committee. The names Molave and Mujigae were chosen to replace Imbudo and Maemi respectively. While Yanyan was requested by Hong Kong to be removed in the list, and was replaced by Dolphin. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) announced that the name Harurot had its name retired due to extensive damage. The name Hanna was chosen to replace Harurot. Also, the name "Koni" was replaced by "Goni", after it was found that Koni was a misspelling.

2003 Pan American Games
The 14th Pan American Games were held in Santo Domingo, Dominican Republic, from August 1 to 17, 2003. The successful bid for the games was made in the mid-1990s, when Dominican Republic had one of the highest growth rates in Latin America.


2003 Pan American Games
All 42 PASO countries and over 5,223 athletes pre-registered for the participation in the XIV Pan American Games. An additional 2,425 trainers and delegates attended. The United States pre-registered the most athletes (713) and Saint Lucia entered the least (6). The host country entered 562 athletes.


2003 Pan American Games, Bids
In December 1998, in Panama City, Panama, Santo Domingo beat Guadalajara, Mexico, and Medellín, Colombia, in the voting to host the games. Guadalajara later went on to host the 2011 Pan American Games.


2003 Pan American Games, Game highlights, Opening ceremony
The games opened at Estadio Olímpico Félix Sánchez before a crowd of 48,000. The exhibition featured some 10,000 performers, some dressed in costumes ranging from skeletons to men in tuxedoes and top hats, typifying a Dominican carnival.

The ceremony also was attended by then-President of the Dominican Republic Hipólito Mejía, Pan American Sports Organization president Mario Vázquez Raña and New York Mayor Michael Bloomberg.


2003 Pan American Games, Game highlights, Budget and venues
The Dominican Republic spent at least $175 million for the 17-day sporting event. Two Olympic parks were renewed or built, the Centro Olímpico Juan Pablo Duarte and Parque del Este complex. Laborers were forced to work right up until the opening ceremony because of construction delays, electrical blackouts, and questionable venue quality. In the end, the Dominican Republic refurbished existing sites and produced beautiful new facilities.


2003 Pan American Games, Game highlights, Budget and venues
Although a few logistical incidents occurred (a team was unable to shower when the athletes village lacked water, teams were missing tennis balls or towels),  U.S. team chief Roland Betts, commented "At times it has been a great struggle, but we are very excited and proud to see the venues. I believe these venues are as good as or better than any that have been created for the Pan American Games." Other attendees agreed that logistical and venue problems declined greatly during the Games.


2003 Pan American Games, Game highlights, Concerns and controversies
Numerous protest marches were staged to call attention to austerity measures, including import taxes and spending cuts, and neglect of impoverished areas. During the Games, the protests were banned from the city. However, the Dominicans warmly embraced the Games with pride, especially when local heroes such as Félix Sánchez won the gold medal in the 400-meter hurdles and broke the Pan Am record.


2003 Pan American Games, Game highlights, Concerns and controversies
While praising the first-rate facilities, critics decried the huge cost overruns, the high payroll of the organizers, and concerns over the Dominican Republic's ability to maintain the venues after the Games.

2003 Pan American Men's Youth Handball Championship
The 2003 American Handball Men's Youth Championships took place in São José dos Pinhais and Curitiba from September 24 – 28.


2003 Pan American Race Walking Cup
The 2003 Pan American Race Walking Cup was held in two locations: both 20 kilometres events in Chula Vista, California, United States, on 15 March. The track of the Cup ran in the Marina Parkway at Chula Vista Marina. The men's 50 kilometres event was held one week earlier 15 km away in Tijuana, Baja California, México, on 9 March.


2003 Pan American Race Walking Cup
Here, the track of the Cup ran in the Paseo de los Héroes, zona del Río Tijuana, and the results were extracted from the inaugural competition of the IAAF World Race Walking Challenge, which was organized as part of the traditional XXVI International Race Walking Week (Spanish: Semana Internacional de la Caminata) held annually since in 1978.


2003 Pan American Race Walking Cup
A detailed report for the 50 kilometres event was given by Javier Clavelo Robinson. Because of a compromise with the transmitting TV companies, the start was scheduled at 10:00 rather than the usual 7:00, causing a great number of drop outs due to the hard climatic conditions during midday.


2003 Pan American Race Walking Cup
The decision to move the start time for Mexican television arguably contributed to the first team loss at the 50 km distance in Pan Am Cup history for the host nation as only two of the five declared Mexican scoring team members finished the race, resulting in a team victory for the United States. The U.S. was the only nation to have three scoring finishers.
