...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 TODAY THROUGH AT LEAST THURSDAY, IMPACTING THE  
ROCK, FOX, DES PLAINES, AND KANKAKEE RIVER BASINS.  
 
VERY COLD TEMPERATURES WHICH HAVE MOVED INTO THE REGION TODAY,  
COMBINED WITH AN EXTENDED PERIOD OF BELOW FREEZING WEATHER OVER THE  
LAST FEW WEEKS, 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 AT LEAST ISOLATED 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.  
 
WHILE WARMING TEMPERATURES LATER THIS WEEK THROUGH THE WEEKEND MAY  
TEMPORARILY REDUCE THE CHANCES FOR ADDITIONAL RIVER ICE FORMATION,  
TEMPERATURES ARE NOT CURRENTLY FORECASTED TO BE WARM ENOUGH TO MELT  
THE ICE. AN ADDITIONAL PERIOD OF VERY COLD TEMPERATURES IS POSSIBLE  
NEXT WEEK WHICH COULD BRING ADDITIONAL RIVER ICE CONCERNS. PERSONS  
ALONG AREA RIVERS SHOULD CONTINUE TO MONITOR THE LATEST FORECASTS  
INTO NEXT WEEK.  
 
THIS PRODUCT WILL BE UPDATED BY TOMORROW AFTERNOON.
