Pittsburgh, PA – Severe thunderstorms could bring damaging winds and flash flooding to Pittsburgh and western Pennsylvania this Sunday, July 27th, threatening travel and outdoor plans across Allegheny County and beyond. Residents along I-376 and other key routes should brace for rapidly changing weather conditions and stay alert for flash flood warnings.
According to the National Weather Service, a Marginal Risk (Level 1 out of 5) exists for severe storms Sunday afternoon and evening, with the primary threats being wind gusts strong enough to topple trees and damage power lines. Showers and thunderstorms may dump heavy rainfall in a short time, increasing the chance for localized flooding, especially in low-lying neighborhoods and near area creeks.
Communities including Pittsburgh, Washington, Monongahela, and Greensburg are likely to see scattered showers and storms develop after 1 p.m. Sunday, with new rainfall amounts potentially reaching up to a half inch in the hardest-hit spots. Motorists should avoid flooded roads, and everyone is urged to secure outdoor items and prepare for possible power outages. PennDOT crews will monitor roads, and local officials encourage residents to report downed lines or blocked roads immediately.
The threat continues into Sunday night before showers taper off early Monday. Daytime highs will push near 88°F Sunday and spike to the lower 90s on Monday, making for a hot, muggy start to the week.
