Synopsis

The Tornado "Season" of 1991 looks generally very average on paper. The spring months of March, April, May and June all saw very large numbers of tornadoes and tornado outbreaks. The fall, sometimes referred to as a "second season", was very quiet. The Andover, Kansas outbreak of April 26, 1991 was famous for its violent tornadoes, incredible video and is the signature event of this tornado season. 1991 saw one F5 tornado touch down in Kansas.

Main article: Andover tornado outbreak

This violent tornado outbreak of 55 tornadoes took place on April 26, 1991, killing 24 people and injuring hundreds more. The killer Andover tornado was rated F5, while four others were rated F4, including the monstrous Red Rock tornado. At the time, the Red Rock tornado generated the highest wind speeds, detected by mobile doppler radar, until the May 3, 1999, Bridge Creek-Moore F5 tornado. This is also the outbreak from which the infamous video was shot by a news crew hiding under an overpass in Kansas. This early viral video spread the myth that sheltering underneath an overpass was safer during a tornado. The television crew was hit by a F2 tornado.
