when does hurricane season start and end in florida
Atlantic hurricane season Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest. However, each particular basin has its own seasonal patterns. On a worldwide scale, May is the least active month, while September is the most active.[1] In the Northern Atlantic Ocean, a distinct hurricane season occurs from June 1 to November 30, sharply peaking from late August through September;[1] the season's climatological peak of activity occurs around September 10 each season.[2] This is the norm, but in 1938, the Atlantic hurricane season started as early as January 3.
Atlantic hurricane season Tropical disturbances that reach tropical storm intensity are named from a pre-determined list. On average, 10.1 named storms occur each season, with an average of 5.9 becoming hurricanes and 2.5 becoming major hurricanes (Category 3 or greater). The most active season was 2005, during which 28 tropical cyclones formed, of which a record 15 became hurricanes. The least active season was 1914, with only one known tropical cyclone developing during that year.[3] The Atlantic hurricane season is a time when most tropical cyclones are expected to develop across the northern Atlantic Ocean. It is currently defined as the time frame from June 1 through November 30, though in the past the season was defined as a shorter time frame. During the season, regular tropical weather outlooks are issued by the National Hurricane Center, and coordination between the Weather Prediction Center and National Hurricane Center occurs for systems which have not formed yet, but could develop during the next three to seven days.
Hurricane Andrew Andrew began as a tropical depression over the eastern Atlantic Ocean on August 16. After spending a week without significantly strengthening itself in the central Atlantic, it rapidly intensified into a powerful Category 5 hurricane while moving westward towards the Bahamas on August 23. Though it briefly weakened to Category 4 while traversing the Bahamas, it regained its Category 5 status before making landfall in Florida on Elliott Key and Homestead on August 24. With a barometric pressure of 922 mbar (27.23 inHg) at the time of landfall in Florida, Andrew is the fourth most intense hurricane to strike the United States. Several hours later, the hurricane emerged over the Gulf of Mexico at Category 4 strength, with the Gulf Coast of the United States in its path. After turning northwestward and weakening further, Andrew moved ashore near Morgan City, Louisiana, as a low-end Category 3 storm. After moving inland, the small hurricane curved northeastward and rapidly lost its intensity, merging with a frontal system over the southern Appalachian Mountains on August 28.
2017 Atlantic hurricane season The season officially began on June 1 and will end on November 30. These dates historically describe the period of year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, as shown by Tropical Storm Arlene in April, the formation of tropical cyclones is possible at other times of the year. Arlene made 2017 the third consecutive year to feature a pre-season storm. In mid-June, Tropical Storm Bret struck the island of Trinidad, which is only rarely struck by tropical cyclones due to its low latitude. A few days later, Tropical Storm Cindy struck the state of Louisiana. In late August, Hurricane Harvey became the first major hurricane to make landfall in the United States since Wilma in 2005, while also setting the record for the costliest tropical cyclone on record, as well as the most rainfall dropped by a tropical cyclone in the US. In early September, Hurricane Irma, a Cape Verde-type hurricane, became the first Category 5 hurricane to impact the northern Leeward Islands on record, and in terms of maximum sustained winds, is tied with the 1935 Labor Day hurricane as the strongest hurricane ever to make landfall in the Atlantic basin. The season also featured the fastest-moving tropical cyclone ever recorded in the Gulf of Mexico (Nate). The season also featured Ophelia, the easternmost major hurricane in the basin on record, which later impacted most of Northern Europe while extratropical.
