Tri State Tornado of 1925

On March 18, 1925 a dark “smokey fog” touched down approximately three miles northwest of Ellington, Missouri. It would become known as the Tri-State Tornado. By all accounts the Tri-State Tornado was one for the record books.

The Tri-State Tornado is currently the U.S. record holder for longest tornado track (219 miles), most deaths in a single tornado (695), and most injuries in a single tornado (2,027). While it occurred before the modern record, it is considered by all accounts to be a F5/EF5 Tornado. It crossed the three states, thus its namesake “Tri-State,” tearing through thirteen counties of Missouri, Illinois, Indiana. It crossed over and destroyed or significantly damaged nine towns and numerous smaller villages.
