The National Weather Service in Pittsburgh is warning residents that remnants of Hurricane Isaias are causing continued flooding across portions of Western Pennsylvania Sunday morning after heavy rainfall left water covering area roadways.
According to an updated flood warning issued at about 8:30 a.m., between 1.5 and 2.5 inches of rain had fallen across the affected region.
The flood warning remains in effect until 10:30 a.m. for Allegheny County, western Westmoreland County, central Washington County, southwestern Butler County and central Beaver County.
Sunday morning, fire and rescue personnel reported flooding on area roadways, according to the National Weather Service.
Forecasters said streams continue to rise because of runoff from earlier rainfall, and it could take several hours for water to move through local drainage systems.
A traffic alert shared on social media by Baldwin Borough said Streets Run Road between Brentwood Road and the City of Pittsburgh was closed due to flooding.
Communities included in the flood warning include Pittsburgh, Penn Hills, Mt. Lebanon, Bethel Park, Ross, Moon, McCandless, Monroeville, Cranberry, Greensburg, McKeesport, among others.
Officials warn that low-water crossings, partially in hilly terrains, can become dangerous during heavy rainfall.
“Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles,” the weather service said.
Meteorologists are warning residents to remain alert to changing conditions and avoid attempting to drive through standing or moving floodwater.
