Power slowly being restored after deadly derecho tears through Ohio, Pennsylvania | 1 May 2025 | A line of severe thunderstorms evolved into a derecho Tuesday evening, bringing destructive wind gusts across parts of the Ohio Valley and interior Northeast, leading to at least three deaths and power outages for hundreds of thousands. By Thursday afternoon, at least 200,000 customers -- mostly in Pennsylvania -- were still without power, down from around 700,000. The strongest impacts were reported in southeastern Ohio and western Pennsylvania, where straight-line wind gusts reached 80 mph -- stronger than many low-end tornadoes but across a much wider area. Officials said the storms tore off roofs, uprooted trees in saturated soil and brought down power lines throughout the region. In Pittsburgh, a man was killed after being electrocuted by live wires, according to the city's public safety department.
