Katrina was the most destructive storm to strike the United States and the costliest storm in U.S. history, causing $108 billion in damage, according to the National Oceanic and Atmospheric Administration (NOAA). It ranks sixth overall in strength of recorded Atlantic hurricanes. It was also a very large storm; at its peak, maximum winds stretched 25 to 30 nautical miles (46 to 55 kilometers) and its extremely wide swath of hurricane force winds extended at least 75 nautical miles (138 km) to the east from the center.
