Storm history of Hurricane Katrina
Katrina made its second landfall at 6:10 a.m. CDT on August 29 as a Category 3 hurricane with winds of 125 mph (205 km/h) near Buras-Triumph, Louisiana. Because Katrina had just weakened from Category 4 strength, and also because of the shape of the coastline, Category 4-force winds are believed to have existed on land while the eye was over water. At landfall, hurricane-force winds were recorded 120 miles (190 km) from the center, the storm's central pressure was 920 mbar (27.17 inHg), and its forward speed was 15 mph (10 km/h). As it made its way up the eastern Louisiana coastline, most communities in Plaquemines, St. Bernard Parish, and Slidell in St. Tammany Parish were severely damaged by storm surge and the strong winds of the eyewall, which also swipped over eastern New Orleans, creating $1 billion worth of damage to the city from intense flooding and wind damage.
