The May 3 Tornadoes: What We Know, What We Learned, and What the Future Holds,
May 26, 1999, Congressional Briefing

Almost every state in the nation is affected by severe tornadoes. In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and over 1,500 injuries. This program presents timely information on the latest research regarding the causes of severe tornadoes, the effectiveness of the warning system and citizen response, and the potential for predicting such storms hours in advance. The violent torndaoes of May 3, 1999, in Oklahoma and Kansas killed over 40 people, leveled thousands of homes and businesses, and disrupted hundreds of thousands of lives. Property losses could top $1 billion. It takes months, possibly years for communities impacted by severe tornadoes to rebuild.
