A flash flood risk remains in effect across Pennsylvania as slow-moving storms bring heavy rainfall through Tuesday. This multi-day weather event is expected to raise concerns about localized flooding in both urban and rural areas.
Flash Flood Risk and Areas Affected
According to the National Weather Service in Pittsburgh, much of Pennsylvania is under a Marginal Risk for flash flooding starting on Friday, with southwestern Pennsylvania facing a Slight Risk for scattered flash floods.
From Saturday through Tuesday, the state will experience unstable conditions, with daily chances of heavy rainfall that could overwhelm drainage systems. Low-lying areas, along with creeks and streams, are particularly vulnerable to flooding.
Potential Impacts in Key Areas
In Pittsburgh, heavy rainfall may cause standing water on major roads, including Route 28, and create delays along the Parkway East. Central Pennsylvania, especially areas like Altoona and State College, could see brief but intense storms.
Additionally, counties in western Pennsylvania such as Greene, Washington, and Indiana are at risk for street flooding, particularly in areas with poor drainage systems.
Safety Measures and Travel Advice
Residents are advised to stay alert for flash flood warnings and take precautions. Avoid driving through flooded roads, as water can rise quickly and cause dangerous conditions.
It’s also important to secure basements and clean storm drains to prevent water buildup. While Sunday may offer a break from the rain, the flash flood risk will return on Monday and Tuesday.
Flash Flood Watches could be issued as the system continues to develop, so it’s important to stay updated by checking local weather alerts daily.
