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.

A couple of tornadoes, hail and wind gusts to 65 mph are possible with these storms. This includes NYC and Philadelphia.  1:05pm. The tornado risk has been extended northward into New York. The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area.

Power outages may occur in this areas. Deep blue i...
