What happened in the Feb. 10, 1959 St. Louis tornado that killed 21 people
A rare overnight winter tornado cut across St. Louis and into Illinois
In the early hours of Feb. 10, 1959, a violent tornado struck the St. Louis region as part of a broader multi-state severe-weather episode that unfolded from Feb. 9 into Feb. 10. The St. Louis-area tornado, later rated F4 on the Fujita scale, produced the deadliest impacts of the event: 21 fatalities and 345 injuries. The tornado’s track began in St. Louis County, moved into the City of St. Louis, crossed the Mississippi River, and then weakened as it continued into Illinois.
Track, timing, and intensity documented after the storm
Post-storm investigations reconstructed a fast-moving path from the Crescent area in St. Louis County through multiple inner-ring municipalities and into the city. The tornado continued northeastward across the river toward the Brooklyn and Venice, Illinois, area before dissipating east of Madison, Illinois. The on-the-ground time has been documented at roughly 35 minutes, with a path length near 24 miles and a maximum width around 200 yards.
Damage estimates compiled in official storm records placed the tornado’s losses at about $50 million in 1959 dollars, with more than 2,000 buildings damaged or destroyed. The scale of structural damage varied along the corridor, with the most intense destruction concentrated where the tornado moved through densely built neighborhoods.
Neighborhood impacts and major structural damage
In St. Louis County, the tornado intensified as it approached the urban core, damaging homes, storefronts, trees, and utility lines in communities along its path. Once inside the city, it caused extensive damage to residential and commercial buildings, including large multi-unit brick structures. Among the notable impacts recorded in storm summaries were damage to the St. Louis Arena’s roof and the toppling of a television transmission tower. Debris and downed utilities complicated rescue operations, and numerous people were reported trapped in collapsed buildings.
Warning limitations and the broader storm context
The 1959 tornado occurred during overnight hours in a season when tornadoes are less common in the Midwest, factors that contributed to limited public readiness. Severe thunderstorm warnings were issued during the storm, but a tornado warning was not in effect ahead of the St. Louis tornado. Documentation from the period reflects the constraints of mid-century severe-weather detection and the difficulty of confirming tornadic signatures in real time.
The St. Louis tornado was part of a larger outbreak that produced multiple tornadoes across the central United States. In the St. Louis area, additional, weaker tornado damage was recorded in St. Louis County the same morning, separate from the F4’s primary damage corridor.
Date: Feb. 10, 1959
Rating: F4
Casualties: 21 dead, 345 injured
Path: St. Louis County into the City of St. Louis, then into Illinois
The event remains one of the most consequential tornadoes in modern St. Louis history because of its night timing, winter setting, and concentrated urban impacts.
