[ORIGINAL, 5:06 a.m.]: Crazy night for folks living and driving near the Schuylkill River:

Wednesday delivered a record rainfall for April 30 — 4.4 inches — with dire results in and around Center City overnight.

Fox 29 reports:

This nasty weather is not going anywhere anytime soon. The National Weather Service has now issued a Flood Warning for parts of the area through early Thursday morning.

The warning is for urban areas and small streams in Berks, Chester, Delaware, Montgomery and Philadelphia counties in Pennsylvania along with northern New Castle County in Delaware until 3:45 a.m., Thursday.

Some areas saw over 4 inches of rain.

CBS Philly added:

Heavy rain pounded the Delaware Valley leading to flooding conditions all throughout the region.

Emergency crews had to rescue dozens of drivers who thought they could make it through standing water. And, in Delaware County, a state of emergency was declared for Marple Township, Darby Borough and the City of Chester.

As KYW’s Tim Jimenez reports, Chester County’s Deputy Director for Emergency Management Robert Kagel says they had to make at least 45 water rescues, drivers underestimating how powerful standing water on the road or at an intersection can be.
