HYDROLOGIC OUTLOOK  
NATIONAL WEATHER SERVICE CHICAGO IL  
1123 AM CST FRI JAN 17 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 FROM SATURDAY THROUGH AT EARLY NEXT WEEK, IMPACTING THE  
ROCK, FOX, DES PLAINES, AND KANKAKEE RIVER BASINS.  
 
BITTERLY COLD TEMPERATURES WILL RETURN TO THE REGION SATURDAY INTO  
SATURDAY NIGHT AND PERSIST THROUGH EARLY NEXT WEEK. 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 TOMORROW AFTERNOON.
