Flash flood watch as heavy rain expected in region

September 21st, 2021 by WCBC Radio

The National Weather Service posted a flash flood watch Tuesday for Western Maryland and the Potomac Highlands, where two to four inches of rain was forecast through Thursday morning. There will be bands of rain and periods of heavy rain Wednesday afternoon and into the evening hours. Although not associated with any “particular tropical system,” moisture from the south and a cold front from the west will join forces to deliver the precipitation. The flash flood watch takes effect at 8 a.m. Wednesday and continues until 8 a.m. Thursday.  With remnants of Hurricane Ida dumping several inches of rain on the region earlier this month, the ground remains mostly saturated, so additional rainfall could be problematic.
