Hydrologic Outlook

...Risk for ice jams and isolated flooding continues...

Favorable conditions for river ice development and possible ice jams
are expected through Wednesday morning, impacting the
Rock, Fox, Des Plaines, and Kankakee river basins.

Bitterly cold temperatures will persist through Wednesday morning.
This will make conditions favorable for the rapid formation of river
ice on area rivers and tributaries. River ice spotters and river
gauge data indicate that most area rivers already have some areas of
heavy river ice including a few minor ice jams. New ice jams will be
possible along the Rock, Fox, Des Plaines, and Kankakee rivers,
including their tributaries. Any ice jam that develops will have the
potential to cause rises on area rivers with little warning and
isolated areas of flooding are possible.

This outlook means that elevated water levels and potential impacts
are possible, but not yet certain. Persons along area rivers should
continue to monitor the latest forecasts into next week.
