NEW ORLEANS – Twenty-one years ago, Hurricane Katrina roared ashore along the Gulf Coast, leaving an indelible mark as one of the deadliest and most destructive disasters in U.S. history.
The cyclone first developed on Aug. 23, 2005, as a tropical depression over the southeastern Bahamas and, within a day, strengthened into Tropical Storm Katrina before moving toward Florida.

The storm stayed compact as it traveled across Florida, and once it reached the warm waters of the Gulf, leading to the explosive intensification of one of the worst hurricanes to ever impact the U.S.
Within 72 hours, Katrina became a Category 5 hurricane with peak sustained winds of 175 mph and a central pressure of 902 millibars.

The storm carved a deadly path across Louisiana, Mississippi, Alabama and the Florida Panhandle, killing more than 1,000 people and causing over $100 billion in damage.
