Outbreak descriptionEdit

A moderate risk of severe weather was issued by the SPC for August 24, with a significant threat for tornadoes, some of which could be strong. The main threat area ran from North Dakota southeastward into Minnesota and northern Iowa to western Wisconsin.[1]

 
Damage from the tornado in Kasota, Minnesota

The tornadoes began about noon central time in North Dakota, with three tornadoes produced there. Then, during the mid-afternoon hours, 11 more tornadoes touched down, 9 of which were in South Dakota. Two of the tornadoes in South Dakota were rated F3 on the Fujita scale - one of which touched passed near the town of Wolsey and another near Eureka. The Wosley storm was one of four tornadoes spawned in the same area from Wessington to Cavour. The three others storms in Beadle County were rated from F0 to F2.[2]

The most destructive tornado of the day was a multiple vortex F3 tornado that hit the Minnesota cities of Nicollet and Kasota. It tracked a path of 33 miles, killed one person, and caused $30 million in damages.[3] This tornado passed near but did not hit the city of St. Peter, which was devastated by the 1998 Comfrey – St. Peter tornado outbreak.

Casualties and damageEdit

One person, a 90-year-old man, was killed when he was pinned by a tree while inside a home in Kasota.[4] Thirty-seven people were reported to have had injuries from that tornado. Five others were injured in the remaining tornadoes on this day, and in all there was $44 million in damages.
