SUMMARY OF RECENT RIVER ICE CONDITIONS BASED UPON SPOTTER REPORTS.
----------------------------------------------------------------------

RIVER ICE SPOTTERS INDICATE WIDESPREAD HEAVY ICE COVERAGE ON NEARLY
ALL AREA RIVERS. A FEW MINOR ICE JAMS HAVE ALSO BEEN NOTED,
INCLUDING ONE ON THE KANKAKEE RIVER NEAR MOMENCE.
MODERATING TEMPERATURES THE NEXT FEW DAYS WILL REDUCE RIVER ICE
GROWTH AND POTENTIALLY LEAD TO SLOW MELTING.
