Rainfall started on Aug. 31 and continued through the night, and is still drenching many locations in Southwestern Pennsylvania. Between 8 a.m. on Aug. 31 and noon on Sept. 1, about 2.25 inches of rain fell, according to the National Weather Service office in Moon Township.
A flood advisory is currently in effect in much of Allegheny County. Westmoreland County and the Mon Valley sections of Allegheny and Washington Counties are currently experiencing flash flood warnings. According to the National Weather Service, most rain is supposed to subside Sept. 1 by the early afternoon.
Evacuations have been called in some areas, and power outages are scattered across Allegheny County. In Bridgeville, which has been hit particularly hard by flooding, the Bethany Church and the fire department are open for shelter.
Here are some of the more dire images of flooding from across the Pittsburgh region:
