StormData Assessment: Oklahoma Tornadoes

On May 3, 1999, over two dozen tornadoes were spawned by multiple supercell thunderstorms in central Oklahoma. The strongest and deadliest moved into Moore and the southern Oklahoma City metropolitan area. The tornadoes claimed 42 lives and 795 people were injured. Over 10,000 homes and businesses were leveled throughout the region with a total damage estimate of $1 billion.

On Tuesday, May 4, 1999, NWS officials in conjunction with the Civil Air Patrol (CAP), conducted an aerial survey of the tornado tracks. The maps and descriptions presented here are the preliminary results of the storm data assessment survey.
