HYDROLOGIC OUTLOOK  
NATIONAL WEATHER SERVICE CHICAGO IL  
913 AM CST SUN JAN 19 2025  
 
...RISK FOR ICE JAMS AND ISOLATED FLOODING INCREASING THE NEXT FEW  
DAYS...  
 
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.  
 
THIS PRODUCT WILL BE UPDATED BY MONDAY AFTERNOON.
