Jul 11, 2019

After a few days of sunshine, extreme weather has hit Pittsburgh again.

Heavy rain and flooding has plagued Allegheny County today and another one to one and a half inches is expected for the afternoon commute between 5 p.m. and 7 p.m.

National Weather Service meteorologist John Darnley said these types of storms form and dissipate quickly, so people should keep an eye out for flash flood warnings.

"Don't drive through the water please, you don't know what's underneath it," Darnley said, "it's been raining all day in some areas and some roads have been washed away."

More than a dozen Allegheny County roads are closed or have restricted access due to flooding, including:

  • Route 1003 (Kittanning Pike) between Kirkwood Drive and Route 28 in O’Hara Township is closed to traffic;
  • Southbound Route 28 near the 31st Bridge in the City of Pittsburgh is closed to traffic;

Additionally, the NWS says a cold front will likely bring severe thunderstorms Thursday afternoon, adding that strong wind and hail were possible. 

In addition to flooding roads, the torrential downpours Thursday triggered landslides and even blocked access to a hospital for several hours.

Allegheny County says access to UPMC St. Margaret hospital was blocked due to flooding. Ambulances were able to access the hospital using a different entrance.

In North Huntingdon, a sinkhole opened up behind a daycare.

People were driving the wrong way on an exit ramp because a stretch of Route 28 was closed.

As for the weekend, NWS meteorologist Lee Hendricks says the rain should subside by Friday.

“Later this afternoon and through the evening hours we’re really looking for everything to taper off to rain showers around midnight tonight, then we’ll finally dry out for the weekend," Hendricks said.
