* At 715 PM CDT, Doppler radar indicated thunderstorms producing
heavy rainfall, moving east across northern Illinois. Earlier
rounds of storms since late Friday night had produced as much as 3
to 4 inches of rainfall along an axis from roughly Sterling and
Peru, eastward into Du Page and portions of northern and central
Cook Counties. Additional rainfall amounts of 1.5 to 2 inches of
rain are possible across these same areas with additional storms
this evening and overnight. This additional rainfall will
exacerbate flooding of low lying and poor drainage areas, and
cause rises on area creeks and rivers.

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

PRECAUTIONARY/PREPAREDNESS ACTIONS…

Be especially cautious at night when it is harder to recognize the
dangers of flooding.
