Winter storm warning issued for tonight through Wednesday evening throughout St. Louis region

The National Weather Service has issued a winter storm warning from 6 p.m. Tuesday through 6 p.m. Wednesday for portions of east central and southeast Missouri and south central and southwest Illinois.

Heavy snow is expected, with total snow accumulation predicted between 4 and 7 inches.

Roads, especially bridges and overpasses, will likely become slick from the rapid accumulation of snow, making travel very difficult, if not impossible The hazardous conditions may impact the Tuesday evening and Wednesday morning commutes.

If travel is necessary, be sure to exercise extreme caution. Keep an extra flashlight, food and water in your vehicle in case of emergency. The emergency alert states, “Do not be fooled, if you are planning travel in an open area, make certain you and your car are prepared for the elements.”

Those traveling should be advised that visibilities will vary greatly across the affected area, and that rural areas will have lower visibility and worse weather conditions than those in towns and cities. Exercise caution when turning onto untreated, lesser traveled roads, side streets and parking lots, since untreated surfaces will be icy and slippery.

Affected areas include but are not limited to St. Louis County, St. Louis city, Jefferson County, Washington County, Warren County and St. Charles County.
