ISSUED AT 1146 AM EDT THU APR 17 2014 NUMEROUS AREAL FLOOD WARNINGS WERE CANCELED TODAY BASED ON UPDATED REPORTS FROM ROAD COMMISSIONS AND EMERGENCY MANAGERS THAT CONDITIONS WERE IMPROVING. FOR NEWAYGO...OSCEOLA...AND ISABELLA COUNTIES THE AREA FLOOD WARNING CONTINUES UNTIL WIDESPREAD IMPROVEMENT IN ROAD CONDITIONS OCCURS DUE TO A RECESSION OF THE FLOOD WATERS. MODERATE TO MAJOR FLOODING ON THE MUSKEGON RIVER CONTINUES WITH A SLOW RECESSION FORECASTED. EVART WILL HOLD ABOVE MAJOR FLOOD STAGE UNTIL SATURDAY NIGHT WHILE CROTON WILL HOLD ABOVE MODERATE FLOOD STAGE UNTIL SATURDAY NIGHT AS WELL. AS SUCH...SIGNIFICANT FLOOD IMPACTS WILL CONTINUE TO PLAGUE PROPERTIES ALONG THE MUSKEGON RIVER THROUGH MUCH OF THE WEEKEND UNFORTUNATELY. THE CROTON DAM OPERATION CONTINUES TO REDUCE FLOWS DOWNSTREAM...LEADING TO A SLOW AND STEADY DECLINE IN RIVER LEVELS FOR INTERESTS IN NEWAYGO AND MUSKEGON COUNTIES. THE GOOD NEWS IS NO SIGNIFICANT RAINFALL IS IN SIGHT OVER THE NEXT SEVERAL DAYS...SO THE RIVER RECESSION WILL CONTINUE. THE PERE MARQUETTE AND CHIPPEWA RIVERS CONTINUE TO HOLD BETWEEN MINOR AND MODERATE FLOOD STAGE WITH BOTH RIVERS EXPECTED TO DROP BELOW FLOOD STAGE WITHIN THE NEXT DAY OR TWO. IMPACTS FROM FLOOD WATERS WILL CONTINUE UNTIL THEN.
