Flash Flood Watch Issued for Philadelphia Region | JQJO

The Philadelphia region is under a flash flood watch from 2 p.m. Monday to 2 a.m. Tuesday due to anticipated heavy rainfall. Up to 5 inches of localized rain is possible as storms approach. The slow-moving cold front responsible is expected to stall, increasing the risk of flash flooding.
