Louisiana's Record Precipitation

The official 24-hour rainfall record for the state of Louisiana was a result of the torrential rainfall caused by tropical disturbance moving north from the Gulf of Mexico. A record 22.00 inches, was observed by a station at the Sabine National Wildlife Refuge in Hackberry, LA on August 28-29, 1962.

Heavy thunderstorms, accompanied by torrential rains occurred over southwestern Louisiana on the evening of the 26th and into the morning of the 29th. Some roads in Lake Charles, and those between there and the coast, were temporarily flooded by water two to three feet deep from the rain.
