Isaias Remnants Flood Roads Across Western Pennsylvania

Heavy rainfall from the remnants of Hurricane Isaias caused flooding across Western Pennsylvania on Sunday morning, covering roadways and prompting warnings in several counties, according to the National Weather Service in Pittsburgh and triblive.com reports.

The National Weather Service in Pittsburgh extended a flood warning until 4:30 p.m. for Allegheny County, western Westmoreland County, central Washington County, southwestern Butler County and central Beaver County.

According to the National Weather Service, a wind advisory also remained active until 2 p.m., with wind gusts on ridgetops and downslope areas potentially reaching 55 mph.

Emergency crews reported flooded roads after 1.5 to 2.5 inches of rain fell across the affected region, the National Weather Service said. Forecasters warned that runoff from earlier rainfall was keeping streams elevated.

The weather service said water could take several hours to move through local drainage systems, increasing risks at low-water crossings, particularly in hilly areas.

A traffic alert from Baldwin Borough said Streets Run Road between Brentwood Road and the City of Pittsburgh was closed because of flooding.

Communities under the flood warning included Pittsburgh, Penn Hills, Mt. Lebanon, Bethel Park, Ross, Moon, McCandless, Monroeville, Cranberry, Greensburg and McKeesport, according to the National Weather Service.

"Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles," said the National Weather Service in Pittsburgh.

Officials advised drivers not to attempt crossing standing or moving floodwater as flooding continued across affected parts of Western Pennsylvania.
