Timeline For Strong Storms, High Winds Tuesday In Eastern PA

Heavy storms with torrential rain and strong winds are in the forecast for Tuesday. A flash flood watch has been issued for southeastern Pennsylvania starting at 11 a.m. and going through the evening.

According to the National Weather Service, thunderstorms producing heavy rain could result in flash flooding across along and near the I-95 corridor.

One to two inches of rain is expected, though three inches or more is possible in some areas.

In addition to the heavy rain, thunderstorms could become severe and produce damaging winds, forecasters warn. The worst of the storms will move through in the afternoon and evening, including during the evening commute, the NWS said.

The Weather Channel, in its hourly forecast, predicts storms will start about 3 p.m. and could continue through nightfall.

"Rapidly rising flood waters may quickly inundate roadways and areas of poor drainage. Streams and creeks could leave their banks, flooding nearby properties. Please monitor the forecast, especially if you live in a location that is prone to flooding," the NWS said.

Skies will clear Wednesday, when sunshine and highs in the upper 80s are predicted.
