Background from Wikipedia

Hurricane Katrina was an extraordinarily powerful and catastrophic tropical cyclone that affected the Southeastern United States in late August 2005, particularly in and around the city of New Orleans. Katrina became the United States' costliest tropical cyclone, with an estimated $125 billion in damages. The hurricane killed 1,392 people, making it the deadliest American hurricane since the 1928 Okeechobee hurricane and is the only mainland U.S. hurricane to have killed over a thousand people since then. Katrina was the twelfth tropical cyclone, the fifth hurricane, the third major hurricane, and the second Category 5 hurricane of the 2005 Atlantic hurricane season. It was also the fourth-most intense Atlantic hurricane to make landfall in the contiguous United States, as measured by barometric pressure.
