The Storm That Crossed Three States: The Tri-State Tornado of 1925
On March 18, 1925, a tornado touched down near Ellington, Missouri and spent the next three and a half hours carving a 219-mile path of destruction through southeastern Missouri, southern Illinois, and southwestern Indiana. It remains the deadliest single tornado in recorded American history.
IN THIS EPISODE:
This episode tells the full story of the Tri-State Tornado — from the quiet Tuesday afternoon when it appeared without warning, through the obliteration of Murphysboro, De Soto, Gorham, West Frankfort, and dozens of other communities, to the haunting aftermath that changed how America thinks about weather preparedness. Personal stories, eyewitness accounts, and the legacy this storm left behind.

METEOROLOGICAL DETAILS:
The tornado began as a classic supercell in Missouri and transitioned to a high-precipitation mode in Illinois and Indiana. Witnesses described a massive wedge tornado — rain-wrapped and so low and wide that many did not recognize it as a tornado until it was upon them. In 1925, there was no tornado warning system, no weather radar, and no public sirens. The storm's death toll was magnified by the complete absence of any advance warning.
LEGACY:
The Tri-State Tornado directly contributed to growing pressure on meteorologists and government officials to develop better storm detection and public warning infrastructure. It took decades and many more tragedies before the National Weather Service tornado warning network came into being — but the memory of March 18, 1925 drove that work forward.
