Western Pennsylvania Slammed by Derecho-Level Storms as Deaths, Power Outages Mount

A massive line of severe thunderstorms — confirmed as a derecho by meteorologists — tore across Western Pennsylvania on Tuesday, leaving behind widespread devastation. With wind gusts reaching up to 95 mph, the storm system caused three fatalities, widespread structural damage, and power outages impacting more than 400,000 customers, many of whom could remain in the dark for up to a week. Counties across the region, including Allegheny, declared states of emergency, while local and state officials continue to assess the need for disaster assistance.

Among the dead was a man electrocuted by downed wires in Pittsburgh and another killed by a falling tree in Ross Township. The third victim, a 25-year-old passenger, died when a tree crushed a vehicle in Greene County. In Edgewood, residents described harrowing scenes as massive oak and maple trees crashed into homes, leaving behind expensive damage and blocked streets. One homeowner described falling to his knees after discovering branches protruding through his third-floor bedroom.

Allegheny County reported over 9,000 emergency calls during the storm, with more than 5,600 coming in just one hour — an unprecedented volume. The 911 system stayed operational despite the overwhelming demand. Public works crews and utility companies, including Duquesne Light, are still working to clear debris and restore services. Over 200 additional utility crews are arriving from surrounding states to aid recovery efforts.

Meanwhile, more severe weather is forecast for Thursday, with additional storms expected to bring winds up to 70 mph and possible hail. Officials continue to warn residents to stay away from downed wires and debris and to remain alert as cleanup and recovery efforts begin across the hardest-hit regions.
