St. Louis, MO – Heavy rainfall is causing flash flooding concerns in eastern Missouri and southern Illinois on July 4th. The National Weather Service in St. Louis reports that thunderstorms are repeatedly moving over areas already saturated by previous rain, leading to significant flash flood potential.
According to the National Weather Service, the heaviest rainfall is occurring along and south of Interstate 70. Rainfall rates are expected to reach 2-3 inches per hour in some areas, exacerbating flood risks. The rain is anticipated to continue through mid-morning before moving east.
Localized flash flooding is a primary concern due to the high volume of rain in a short period. Residents are urged to avoid driving on flooded roadways, as vehicles can easily stall or be swept away by flowing water.
Authorities recommend monitoring local weather reports and heeding any flash flood warnings. The NWS advises that the areas most affected include Jefferson City, St. Louis, and extending east into parts of Illinois, including Mt. Vernon.
