Flood Watch
National Weather Service Chicago IL
938 AM CDT Sat Sep 19 2026
...The National Weather Service in Chicago has issued a Flood Watch
for the following rivers in Illinois...
Des Plaines River near Russell affecting Lake IL County.
Des Plaines River near Gurnee affecting Lake IL County.
Des Plaines River at Lincolnshire affecting Cook and Lake IL
County.
Des Plaines River near Des Plaines affecting Cook County.
Des Plaines River at Riverside affecting Cook County.
.The combination of heavy rain this morning and expected additional
thunderstorms with heavy rain tonight may lead to river flooding
along the Des Plaines River basin as early as Sunday morning. The
heavy rain tonight is expected to occur along a roughly west to east
axis across northern Illinois, though the exact location across the
river basin remains uncertain. Flooding severity may be higher or
lower over the basin depending on the ultimate placement of the
highest rainfall tonight.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Flood Watch means water levels above flood stage are possible, but
not yet certain, based upon the latest forecasts. Persons along
rivers and streams in the watch area should monitor the latest
forecasts and be prepared to take action should flooding develop.
These forecasts are based on observed precipitation as well as
forecast precipitation 24 hours into the future. Changes to the
rainfall forecast, or any additional rainfall after 24 hours, may
cause changes to these river forecasts.
Additional information is available at www.weather.gov.
The next statement will be issued by late tonight.
