Philadelphia weather: Flash flooding in multiple counties as torrential rain pushed through area

Sunny and humid conditions once again gave way to a round of severe storms Wednesday night.

Scattered storms moved through with periods of heavy rainfall and they are expected to last into the early morning hours of Thursday.

Flash flooding inundated multiple counties as first responders were called to reports of cars stranded on Route 1 in Delaware County while buildings were experiencing flooding in Wilmington.

What we know:

A Flood Watch has been issued for the entire region for periods of heavy rain that could exceed 2 to 3 inches per hour in some places. Very heavy rainfall is slated to fall over large swaths of Delaware, South Jersey and into the Lehigh Valley, and could last into the early morning hours.

The stage is set for flash flooding into the overnight hours as the ground is already saturated. There is no place for the water to go.

Emergency alerts were issued Wednesday night for Flash Flood Warnings as copious amounts of rain had begun to fall across multiple counties. That rainfall is moving across the region and is drenching South Jersey and Delaware.

The National Weather Service says isolated thunderstorms could also bring strong wind gusts.

What's next:

The Philadelphia-area will remain locked in the classic mid-summer weather pattern of sunny humidity followed by rounds of scattered storms in the afternoon and evening.

While the next several days won't be a washout, forecasters expect the chance of pop-up storms to remain throughout the weekend.
