At 447 PM CDT, Law enforcement and the Department of Transporation
was reporting flooding across the area. This flooding is the result
of runoff from 4 to 7 inches of rainfall that has fallen since late
Friday. Flooding will continue on area creeks, streams, poor
drainage areas, and roads which are often subject to minor flooding.

Some locations that will experience flooding include...
St. Louis, St. Charles, St. Peters, Florissant, Chesterfield,
Belleville, Wildwood, University City, Ballwin, Granite City,
Wentzville, O'Fallon, Alton, Kirkwood, Maryland Heights, East St.
Louis, Hazelwood, Collinsville, Edwardsville and Webster Groves.

This also includes Babler Memorial State Park, Scott Joplin
Historic Site, Route 66 State Park, Castlewood State Park,
Confluence State Park, Mastodon Historic Site, Sandy Creek Covered
Bridge Historic Site, Gov. Dunklin's Grave Historic Site, First
Missouri State Capitol Historic Site, Robertsville State Park,
Meramec State Park, Carlyle Lake Recreational Area, and Horseshoe
Lake State Park.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, country roads, farmland, and other low lying
spots.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.
