Hurricane Katrina The storm originated over the Bahamas on August 23, 2005, from the merger of a tropical wave and the remnants of Tropical Depression Ten. Early on the following day, the new tropical depression intensified into a tropical storm and headed generally westward toward Florida, strengthening into a hurricane only two hours before making landfall at Hallandale Beach and Aventura on August 25. After very briefly weakening again to a tropical storm, Katrina emerged into the Gulf of Mexico on August 26 and began to rapidly intensify. The storm strengthened into a Category 5 hurricane over the warm waters of the Gulf,[4] but weakened before making its second landfall as a Category 3 hurricane on August 29, over southeast Louisiana and Mississippi. As Katrina made landfall, its front right quadrant, which held the strongest winds, slammed into Gulfport, Mississippi, devastating it.[5]
