Lying within the hotbed of [[Tornado Alley]], St. Louis is one of the most frequently tornado-struck metropolitan areas in the U.S. and has an extensive history of [[St. Louis tornado history|damaging tornadoes]]. Severe flooding, such as the [[Great Flood of 1993]], may occur in spring and summer; the (often rapid) melting of thick snow cover upstream on the Missouri or Mississippi Rivers can contribute to springtime flooding.{{Citation needed|date=November 2024}}
