‘WORST TORNADO’ — THE TRI-STATE TORNADO, WHICH HAS BEEN DEEMED THE WORST TWISTER IN U.S. HISTORY, SWEPT THE MIDWEST on Wednesday, March 18, 1925. The tornado, which was part of an outbreak hitting other parts of the South, materialized around 1 p.m. local time at Ellington, Missouri, which is located in the East-Central part of that state. The twister then traveled northeast (the typical tornado path) for 219 miles, hitting southern Illinois the hardest and claiming 695 lives, more than 500 of whom were in southern Illinois. More than a mile wide, the tornado exceeded more than 70 mph and spent more than three hours on the ground on its way to southwestern Indiana, cutting a path of devastation of 164 square miles.
At that time, the technology now available to track tornadoes locally, such as WSR-88 Doppler radar, had not yet been developed. The Fujita scale of wind intensity would not go into use for another 45 years.
