Flash Flood Watch/Storm Warning Wednesday August 12th

Flash Flood Watch

Heavy rain leading to flash flooding will be possible today into this evening.

Hazardous Weather: Showers and thunderstorms today and tonight will be capable of heavy rain. Much of the region is more vulnerable than normal to flash flooding due to the heavy rain last week, so it may not take as much rain today to cause flash flooding.

Locations affected:
The highest risk for heavy rain leading to flash flooding is across northern Delmarva, much of southeastern Pennsylvania, and portions of southwestern, central, and northern New Jersey (see the attached graphic).

Timing: Although showers and thunderstorms will be possible through the day and overnight, the period of greatest concern is this afternoon and this evening.
