Hurricane Katrina began as Tropical Depression Twelve over the southeastern Bahamas on August 23, 2005. The depression later strengthened into a tropical storm on the morning of August 24 where the storm was also named Katrina. Katrina continued to move into Florida, and became a Category 1 hurricane only two hours before it made landfall around Hallandale Beach on the morning of August 25. The storm weakened over land, but became a hurricane again while entering the Gulf of Mexico.
