Pittsburgh, Pa. – Drivers and residents across Pennsylvania should brace for a wet start to the weekend as strong thunderstorms and heavy rain return Friday, July 18th. With saturated grounds and showers expected to linger, the Parkway East and other Pittsburgh roadways could see flash flooding and hazardous travel conditions through Saturday.
According to the National Weather Service, a marginal risk for storms begins Friday morning and intensifies into Saturday, with showers and thunderstorms likely from 11 a.m. onward. Some storms could dump enough rain to trigger localized flash flooding—especially in low-lying areas and along frequently traveled routes like Parkway East. Showers will continue overnight into Saturday and Sunday, with rainfall amounts ranging from a quarter inch to one inch or more in the heaviest downpours.
Residents should avoid driving through flooded roads and monitor local advisories, especially if traveling on major arteries like Parkway East, I-376, or heading toward Allegheny County’s riverfront areas. Charge devices, prepare for possible power outages, and keep an eye on updated alerts throughout the weekend.
Showers could linger into early next week, with a chance for thunderstorms each day through Wednesday, July 23rd. More advisories are possible as new systems approach.
