...River Ice to Expand This Weekend due to Very Cold Temperatures...



Recent reports from river ice spotters and river gauges indicate 

that some melting of ice has occurred over the last few days, but 

isolated areas of heavy river ice coverage continue. Very cold 

temperatures this weekend will cause river ice to expand in 

coverage. Ice jams will be possible in isolated areas along the 

Rock, Fox, Des Plaines, and Kankakee rivers into early next week. 

Ice jams may cause rises on area rivers with little warning.



Warmer temperatures may return to the area by late next week, which 

could begin a slow melt of river ice.

         

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 outlook may be updated by tomorrow afternoon.
