World's Largest Collection of Hurricane Katrina Pictures

Hurricane Katrina was the eleventh named tropical storm, fifth hurricane, third major hurricane, and first Category 5 hurricane of the 2005 Atlantic hurricane season. It was the third most powerful storm of the season, and the sixth-strongest Atlantic hurricane ever recorded. Katrina formed over the Bahamas in late August, and crossed southern Florida at Category 1 intensity before strengthening rapidly in the Gulf of Mexico. The storm weakened considerably before making its second landfall as an extremely large Category 3 storm on the morning of August 29 along the Central Gulf Coast near Buras-Triumph, Louisiana.

The storm surge from Katrina caused catastrophic damage along the coastlines of Louisiana, Mississippi, and Alabama. Levees separating Lake Pontchartrain from New Orleans were breached by the surge, ultimately flooding about 80% of the city. Wind damage was reported well inland, impeding relief efforts. Katrina is estimated to be responsible for $75 billion in damages, making it the costliest hurricane in United States history; the storm has killed at least 1,383 people, becoming the deadliest U.S. hurricane since the 1928 Okeechobee Hurricane.
