Hydrologic Outlook
National Weather Service Chicago IL
328 PM CDT Tue Apr 9 2024

...Rainfall may lead to flooding late this week...

Flooding of rivers, creeks, ditches, and poor drainage areas
possible across northeastern Illinois and northwestern Indiana later
this week. Significant river rises and renewed flooding possible
along the Iroquois, Kankakee, Des Plaines, Fox, and Illinois rivers.

Rainfall is expected to develop and move into the Midwest during the
day on Wednesday and continue through Thursday night. Widespread
rainfall of at least half an inch is likely, with localized totals
near 2 to 3 inches possible. Runoff from this rainfall will be
increased due to high soil moisture values across the region due to
recent wet weather. Significant rises are possible on area streams
and rivers, including the possibility of renewed flooding on the
Iroquois, Kankakee, Des Plaines, Fox, and Illinois rivers and their
tributaries. In addition to flooding of larger rivers, flooding of
fields, ditches, and poor drainage areas may also occur. Confidence
in the exact placement of rainfall and the exact rainfall totals
remains low at this time, which prevents more specific forecasts.

This outlook means that elevated water levels and potential impacts
are possible, but not yet certain. Persons with interests along area
rivers should closely monitor the latest forecasts including the
possibility of flood watches, warnings, and advisories.

This product may be updated tomorrow if the possibility of heavy
rainfall and flooding continues.
