Midwest: Flash Flood Update

By -

There is a serious risk of flash flooding tonight in the outlined area. Rainfall amounts in places will exceed six inches. 

Whatever you do, do not try to cross flooded areas by foot or by car. If you live in a flood-prone area, put together a "go kit" of family heirlooms and other essentials in your car now so that you can quickly move to higher ground if water begins rising rapidly.

Over the northern half of Illinois, heavy rains will develop after midnight giving a risk of flash flooding but the risk is not quite as great as in the outlined area. 

Addition: 5pm
National Weather Service flash flood watch in green. Yellow is their tornado watch.
