Summary
Hurricane Katrina formed over the Bahamas on August 23, 2005, crossed southern Florida as a Category 1 storm, then intensified rapidly over the warm waters of the Gulf of Mexico, reaching Category 5 status with peak sustained winds near 175 miles per hour. The storm weakened before making its second landfall in southeastern Louisiana on the morning of August 29 as a Category 3 hurricane, driving a catastrophic storm surge into the Gulf Coast of Louisiana, Mississippi, and Alabama.
The greatest disaster unfolded in New Orleans, where the federally built levee and floodwall system failed in more than 50 locations. The breaches allowed water to inundate roughly 80 percent of the city, much of which lies below sea level, with floodwaters reaching depths of several meters in some neighborhoods. Tens of thousands of residents who had not evacuated sought shelter at the Louisiana Superdome and the Ernest N. Morial Convention Center, where overcrowding, failing sanitation, dwindling supplies, and delayed rescue produced a prolonged humanitarian crisis.
The storm caused approximately 1,800 deaths and an estimated $125 billion in damage, making it the costliest hurricane in United States history at the time. The federal response, coordinated through the Federal Emergency Management Agency under Director Michael Brown, was widely criticized as slow and poorly organized; Brown resigned in September 2005. Hundreds of thousands of Gulf Coast residents were displaced, many permanently relocating to other cities and states.
Significance
Hurricane Katrina ranks among the deadliest and most destructive natural disasters in U.S. history and exposed deep failures in flood-control engineering, emergency preparedness, and intergovernmental coordination. The disaster prompted investigations into the U.S. Army Corps of Engineers’ levee design, reforms to FEMA and national emergency management, and a sustained national debate over poverty, race, and the uneven impact of the catastrophe on vulnerable communities. Its aftermath reshaped New Orleans demographically and influenced subsequent infrastructure and disaster-response policy.
