A series of storms socked the Northeast with heavy rains and strong winds Thursday.
The rain started falling Thursday and continued through early Friday in most areas. The storms quickly intensified, causing minor to major flash flooding in several states and possibly spawning a tornado in a southern New Jersey town.
Floodwaters closed several streets in the Pittsburgh area Thursday night, but most had reopened by morning. The storms also knocked down trees and power lines, causing sporadic power outages across the region.
Portions of southeastern Massachusetts were hammered by heavy rain overnight, with the National Weather Service reporting that more than 5 inches (12.7 centimeters) fell over a six-hour period in Plymouth. Some road closures were reported, but no injuries. A flood warning was in effect for Provincetown, at the tip of Cape Cod, until midmorning Friday.
In New Jersey, National Weather Service investigators were examining whether a tornado touched down in Mount Laurel Township on Thursday evening. Trees were toppled and radar indicated the possibility of a tornado.
Parts of New Jersey received more than 3 inches (7.62 centimeters) of rain from the storm.
