FLOOD WATCH
NATIONAL WEATHER SERVICE NORTHERN INDIANA
432 AM EST FRI DEC 20 2013
…HEAVY RAINFALL AND POTENTIAL FLOODING THIS WEEKEND…
A strong storm system will organize across the southern plains on Saturday and move toward the southern great lakes and Ohio valley regions through late Sunday. Rain is expected to overspread the area Saturday afternoon and continue into Sunday. Rainfall will be heavy at times, especially Saturday evening into Sunday morning. While the exact track of the heaviest precipitation is still uncertain, the potential exists for 1 to 3 inches of rainfall. In addition, warmer air surging northward will allow for continued melting of the existing snowpack. The combination of runoff from heavy rainfall and snowmelt may lead to flooding of streams and creeks along with low lying areas. River levels across the Maumee and Wabash basins will likely see significant rises and potential flooding into next week.
