Heavy, slow-moving downpours caused severe flash flooding across western Pennsylvania on Friday night. The most severe flooding was reported in Allegheny, Fayette and Washington counties. A Flash Flood Warning was in effect for much of the evening for several parts of the area. In Allegheny, Armstrong and Butler counties, the warning was issued until 4:15 a.m. Saturday.
Flooding in several areas, including Scott Township, Baldwin, Greentree, Springdale and Oakmont. Route 51 had to be shut down in spots due to high waters. In Fayette County, the flooding was so severe emergency officials were warning residents to stay off the roads completely. The hardest hit areas are Georges and Union Townships and Hopwood. In Masontown, a creek rose over its banks, flooding Smithfield-Masontown Road. The water was deep enough that no cars could get through. In South Uniontown, Lebanon Avenue near the shopping plaza also flooded. A truck managed to drive through the flood waters but no one else was attempting it until the water receded.
In the city of Little Washington, the rain came down fast and furious at times. The downpours caused numerous problems, including street closures, like at the intersection of Washington and West Chestnut Streets. Many water rescues took place, no injuries or deaths have been reported.
