Philadelphia, PA – Drivers across Pennsylvania are being urged to prepare today as forecasters warn that fast-moving snow squalls may form this season, bringing sudden whiteouts and rapidly deteriorating road conditions just as early holiday travel begins to increase. The system could affect areas from Philadelphia to Harrisburg, Pittsburgh, and along major turnpike corridors.
Snow squalls are brief—typically under an hour—but among the most dangerous winter weather hazards. Strong winds, heavy snow, and flash-freezing pavement have historically contributed to multi-vehicle crashes throughout the state when drivers encounter whiteout conditions at highway speeds. Officials repeatedly warn that avoiding the road during a Snow Squall Warning is the safest option.
If you’re already driving when a squall hits, experts advise slowing down gradually, turning on hazard lights, and increasing following distance significantly. Drivers should stay in their lane, avoid sudden braking, and never stop in a travel lane where visibility is extremely limited. Safe pull-off areas—such as rest stops, exits, or lots—are recommended until conditions pass.
Pennsylvania residents running errands, commuting, or heading to early holiday events should keep winter emergency kits in their vehicles. Essentials include blankets, water, backup chargers, ice scrapers, and traction material such as sand or cat litter. Homeowners should also secure loose outdoor items in case squalls bring brief but strong wind gusts.
Forecasters will continue monitoring conditions throughout the afternoon, with the potential for additional warnings.
