The 2011 St. Louis tornado was a storm that struck the St. Louis metropolitan area on April 22, 2011. It was part of the April 19–24, 2011 tornado outbreak sequence.
The tornado, rated EF4 at its strongest point with winds exceeding 165 mph, was the strongest to hit St. Louis County or City since January 1967. The tornado moved through many suburbs and neighborhoods, damaging and destroying many homes and businesses. The worst damage was in the Bridgeton area, where a few homes were completely leveled. In its 22-mile track across the St. Louis metropolitan area, the tornado damaged thousands of homes, left thousands without power, and caused heavy damage to St. Louis Lambert International Airport, closing it for nearly 24 hours. The tornado crossed into Illinois and tore the roofs off of homes in Granite City before dissipating.
The tornado initially touched down near Creve Coeur Lake around 7:55 p.m. and moved into Maryland Heights where it produced EF3 damage. The tornado continued eastward and reached EF4 intensity in Bridgeton where a number of houses were completely destroyed. Afterwards the tornado traveled parallel to I-70 and struck Lambert-St. Louis International Airport, blowing out numerous windows and peeling away a large section of roof. The tornado then moved into the Berkeley neighborhood where it continued to produce EF2 damage, tearing the roofs from several homes. The tornado continued on through several more neighborhoods, causing roof damage to a church and two businesses, one of which completely lost its roof. The storm also produced extensive tree damage and some roof damage to homes as well as partially removing the roof of an elementary school. Damage along this entire section of the pat was rated EF1 to low end EF2. The tornado continued towards the Mississippi River producing mostly EF1 damage to trees, however EF2 damage occurred in Dellwood where extensive tree and utility pole damage occurred and three homes lost their roofs. EF2 damage continued as the tornado crossed into Illinois where about a hundred homes were damaged, three of which lost their roofs, and numerous trees were uprooted and snapped.
