Pittsburgh, Pa. — Widespread snowfall spreads across western Pennsylvania Friday, creating increasing travel hazards along I-79, I-376, and I-70 as road conditions deteriorate through the day.
The National Weather Service in Pittsburgh urged drivers to prepare ahead of time and use official travel resources as snow overspreads the region. Accumulating snow is expected to lead to snow-covered roads, reduced visibility, and longer braking distances during daytime and evening travel.
The most significant impacts focus on major commuter corridors, including I-79 from Washington County north through Butler County, I-376 through the Pittsburgh metro area, and I-70 west of the city toward the Ohio border. Secondary roads and elevated surfaces turn slick quickly once snowfall intensifies.
Communities likely to see hazardous travel include Pittsburgh, Washington, Beaver, Butler, Greensburg, New Castle, and Indiana. Urban interstates may initially remain wet, but conditions worsen rapidly as snow rates increase and temperatures fall.
Officials encouraged drivers to monitor real-time road conditions before traveling. In Pennsylvania, motorists can check 511pa.gov for updated highway conditions. Travelers crossing into neighboring states should also use wv511.org in West Virginia and ohgo.com in Ohio to track road impacts as the storm evolves.
The Weather Service also asked residents to report snowfall totals using official reporting tools, including online submission forms and social media, to help improve storm tracking and forecast accuracy.
Drivers are urged to slow down, allow extra travel time, and avoid sudden braking as snow accumulates. Even light snowfall can cause major delays during high-traffic periods.
Snow continues into the evening before gradually tapering overnight. Road conditions may remain hazardous into early Saturday as crews work to clear snow-covered pavement.
Officials stress that preparation and situational awareness are key as this winter system brings another round of disruptive travel conditions to the Pittsburgh commuter corridor.
