Hurricane Katrina moved ashore over southeast Louisiana and southern Mississippi early on August 29, 2005, as an extremely dangerous Category 4 storm. With winds of 135 miles per hour (217 kilometers per hour), a powerful storm surge, and heavy rains, Katrina pounded the U.S. Gulf Coast, triggering extensive life-threatening flooding.
This GOES satellite image shows the storm as it moved over southern Mississippi at 9:02 a.m. The eye of the storm was due east of New Orleans.
By mid-afternoon on August 29, Katrina had weakened into a Category 1 hurricane with winds of 95 mph (153 km/hr). A mere 24 hours earlier, Katrina had been one of the most powerful storms ever observed in the Atlantic Basin.
