Summer weather in Pittsburgh takes a turn for the worse on Sunday, July 20th, as dangerous storms and a risk of flooding move into the area. Heavy rainfall, strong winds, and possible flash flooding will affect the Pittsburgh region, particularly along major roadways like Parkway East (I-376).
Storm and Flooding Risks
The National Weather Service has issued a Marginal Risk for excessive rainfall across Allegheny County, with showers and thunderstorms expected to push into the area during the late morning. Storms will intensify after 1 p.m., bringing the possibility of damaging winds and localized flooding. Low-lying neighborhoods and areas near creeks are at the highest risk for minor flooding.
Safety Tips for Residents
Local officials are urging everyone to avoid driving through high water, especially on flood-prone routes like Route 51 and Parkway East. If you live in areas with poor drainage, make sure to secure outdoor items and prepare for brief power outages. Rain will taper off by Sunday night, although scattered showers may linger.
Looking Ahead to Calmer Days
The stormy weather will give way to calmer conditions on Monday, with sunshine and temperatures in the mid-80s. By Wednesday, Pittsburgh will see a return to summer heat, with temperatures reaching into the low 90s and heat indices pushing the upper 90s through Friday. Residents are advised to limit outdoor activities, stay hydrated, and check on vulnerable neighbors as the heat intensifies.
