Hydrologic Outlook
National Weather Service Chicago IL
1053 AM CST Wed Jan 23 2019

...Risk for river ice and ice jams increasing next several days...

Favorable conditions for river ice formation and possible ice jams
developing for the following rivers and their tributaries...

Rock, Fox, DuPage, Des Plaines, Iroquois, and Kankakee in
northern Illinois, and Iroquois, and Kankakee in northwest
Indiana.

...through at least early next week.

Due to recent cold weather and additional very cold temperatures
expected over the next several days, conditions are favorable for
river ice formation. River ice has caused at least one ice jam
in northern Illinois over the last few days. Rapid development of
river ice may lead to additional ice jams, causing rises on area
rivers with little warning.

This outlook means that elevated river conditions and potential
impacts are possible, but not yet certain. Those with interests
along area rivers should closely monitor future river forecasts.
