The storms started Wednesday night and continued for several hours through early Thursday. It was the latest round of severe weather in the region in recent days, and officials say the combined storms have left the ground saturated.
More rain is expected later Thursday and a flash flood warning has been issued for Philadelphia and its suburban counties.
The flooding forced the closures of several roads. Commuter rail service between Philadelphia and New Jersey was also suspended for several hours due to storm damage.
The storms also caused the roof of a supermarket to collapse. Employees who were inside the store said the collapse caused pipes in the sprinkler system to break, sending water throughout the business. But all the workers got out safely.
