PENNSYLVANIA — Residents across southeast Pennsylvania should prepare for the potential for flash flooding Monday afternoon and night as the National Weather Service has issued a Flood Watch for the region.
The Flood Watch is in effect from 2 p.m. Monday through late Monday night for Delaware, Philadelphia, Bucks, Chester and Montgomery counties.
Forecasters say showers and thunderstorms are expected to develop this afternoon and continue into the evening, producing rainfall rates of 1 to 2 inches per hour. Those rainfall rates could quickly overwhelm drainage systems, especially in urban and poor-drainage areas, leading to flash flooding.
The National Weather Service says flooding is most likely in cities, neighborhoods with poor drainage and other flood-prone locations. Heavy downpours may also cause water to collect on roadways and in low-lying areas.
According to the forecast, widespread showers and thunderstorms are expected through tonight, with the greatest risk of heavy rainfall occurring later this afternoon and evening. Forecast confidence in the flooding threat is high.
Residents are urged to closely monitor changing weather conditions and be prepared to take action if Flash Flood Warnings are issued. Motorists are reminded never to drive through flooded roadways, as water can quickly become deeper and more dangerous than it appears.
