A POTENT STORM SYSTEM WILL CONTINUE TO IMPACT NORTHERN ILLINOIS
AND NORTHWEST INDIANA THROUGH TONIGHT. NUMEROUS ROUNDS OF MODERATE
TO AT TIMES HEAVY RAINFALL CAN BE EXPECTED TODAY AND TONIGHT.
SOILS ACROSS THE AREA ARE NOT COMPLETELY SATURATED...WHICH SHOULD
ALLOW SOME OF THE PRECIPITATION TO FILTER INTO THE GROUND.
HOWEVER...WITH THE EXPECTED PERIODS OF HEAVY RAINFALL AND ISOLATED
CONVECTION THIS WILL ADD TO THE RUNOFF AND FLOW INTO AREA STREAMS.
ADDITIONAL PRECIPITATION TOTALS EXPECTED THROUGH TONIGHT SHOULD BE
BETWEEN 0.7 AND 1.1 INCHES. THE HIGHEST PRECIPITATION TOTALS ARE
EXPECTED TO FALL ALONG AND WEST OF A WAUKEGAN TO PONTIAC LINE.
THIS MAY BE SUFFICIENT TO CAUSE SOME LOCATIONS TO RISE ABOVE
BANKFULL AND POSSIBLY TO FLOOD STAGE. THE HIGHEST RISK FOR
STREAMFLOW RISES WILL BE ACROSS THE KANKAKEE WATERSHED. FLOWS HERE
HAVE REMAINED ELEVATED FROM RECENT RAINFALL.
PERSONS LIVING IN LOW LYING FLOOD PRONE AREAS SHOULD CONTINUE TO
CLOSELY MONITOR THIS DEVELOPING WEATHER SITUATION.
