Storm history of Hurricane Katrina
Katrina struck the peninsula at a high speed with 80 mph (130 km/h) winds, and had a well-defined eye on Doppler radar, which managed to stay undisturbed throughout its passage over Florida. The storm weakened over land on August 26 to a tropical storm, but regained its strength as a hurricane at 2:00 a.m. EDT (0600 UTC), about one hour after making landfall in Florida. Parts of the Florida Keys experienced tropical storm force winds throughout August 26, with the Dry Tortugas briefly experiencing hurricane-force winds.
