332 PM CDT Thu Jun 21 2018

... A Flood Warning remains in effect until 845 PM CDT for eastern
will... dupage and Cook counties...

At 331 PM CDT, Doppler radar and rainfall observations indicated
that one to locally upwards of three inches of rain had fallen
through early this afternoon over portions of Cook, dupage, and will
counties. While a lull in the widespread heavy rain is expected
through early evening, heavy rain could redevelop later this evening
or overnight.

Areas of flooding are expected to persist into this evening due to
runoff from the heavy rain that already fell today. Low-lying areas,
ditches, poor drainage locations, and viaducts or underpasses will
be most vulnerable to flooding, including in the Chicago area during
the late day commute.

Some locations that will experience flooding include...
Chicago, Cicero, Arlington Heights, Evanston, Schaumburg,
Bolingbrook, Palatine, Skokie, Des Plaines, Orland Park, Tinley
Park, Oak Lawn, Berwyn, Mount Prospect, Wheaton, Hoffman Estates and
Oak Park.

Precautionary/preparedness actions...

Excessive runoff from heavy rainfall will cause ponding of water in
urban areas... highways... streets and underpasses as well as other
poor drainage areas and low lying spots. Do not attempt to travel
across flooded roads. Find alternate routes. It takes only a few
inches of swiftly flowing water to carry vehicles away.
