Tropical Depression Ten was a precursor of Hurricane Katrina during the record-breaking 2005 Atlantic hurricane season. It formed on August 13 from a tropical wave off the west coast of Africa, but the depression faced strong wind shear and remained weak. By August 14, it no longer met the criteria for a tropical cyclone, and the National Hurricane Center issued their final advisory on it. Moving westward, the storm produced occasional bursts of atmospheric convection. By August 18, only a remnant mid-level circulation persisted. This merged with a second tropical wave on August 23 to form Tropical Depression Twelve, which grew into Katrina, the third most intense tropical cyclone ever to make landfall in the United States. Katrina was the costliest US disaster until Hurricane Harvey in 2017, and one of the deadliest Atlantic hurricanes, causing severe destruction along the Gulf Coast from central Florida to Texas, much of it due to storm surge and levee failure. At least 1,245 people died in the hurricane and subsequent floods.
