Pittsburgh, PA – The weather is expected to turn active on Sunday, July 20th, as the region faces the threat of dangerous storms and flooding risks. Heavy rainfall, strong winds, and flash flooding could impact Pittsburgh, with major roadways like Parkway East (I-376) being particularly vulnerable.
The National Weather Service has issued a Marginal Risk warning for excessive rainfall across Allegheny County through the afternoon, starting late morning and intensifying after 1 p.m.
Storms and Flooding Risk
The storm system is likely to bring showers and thunderstorms, some of which may produce damaging winds. Localized flooding could occur in low-lying areas and near creeks, with the heaviest rain expected in these spots. Parkway East and Route 51, both prone to flooding, should be avoided if possible.
Residents in areas with poor drainage are advised to secure outdoor items and prepare for possible power outages. By Sunday evening, the rain should taper off, though scattered showers may persist.
Bright Days Ahead, Then Heat Returns
Monday will bring a break in the weather with sunshine and calm conditions, with highs in the mid-80s. By Wednesday, the heat will intensify, with temperatures expected to soar into the low 90s.
The heat index could push the mercury even higher, so it’s important to stay hydrated, limit outdoor activities, and check on vulnerable neighbors. The heat will persist through the end of the week, with isolated thunderstorms possible later in the week.
