Hydrologic Outlook

1232 PM CST Wed Feb 12 2025

...Risk for river ice formation and ice jams increasing late this
week through next week...

Favorable conditions for river ice development and possible ice jams
are expected beginning Friday and continuing into the weekend,
impacting the Rock, Fox, Des Plaines, and Kankakee river basins.

Very cold temperatures, favorable for rapid formation of river ice
on most areas rivers, are expected Thursday through Friday and again
early next week. The formation of heavy river ice cover means that
ice jams will be possible in isolated areas, especially along the
Rock, Fox, Des Plaines, and Kankakee rivers. Ice jams may cause
rises and fluctuations on area rivers with little warning.

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.

This product will be updated by tomorrow afternoon.
