I-95 and I-76 in Philadelphia, Pennsylvania – Travel across the Philadelphia region could become extremely hazardous beginning Saturday night as a major winter storm brings widespread accumulating snow and significant roadway impacts into early Monday afternoon.
According to the National Weather Service in Philadelphia/Mount Holly, confidence continues to increase that a high-impact winter storm will affect much of eastern Pennsylvania, New Jersey, and Delaware. Forecasts show a 70–90% probability of major winter weather impacts for most of the region, driven primarily by heavy, accumulating snow.
Major highways including I-95, I-76, I-476, the New Jersey Turnpike, and Route 42 are expected to experience snow-covered pavement, reduced visibility, and prolonged slow or stalled traffic. The Weather Service warns that snow-covered roads and reduced visibility will cause widespread travel disruptions, particularly during periods of heavier snowfall Saturday night and Sunday.
While snow is expected to be the dominant precipitation type, forecasters note that snow may mix with sleet or freezing rain at times across southeastern Pennsylvania, southern New Jersey, and the Delmarva Peninsula on Sunday. This mixing could reduce snowfall totals in some areas but would increase the risk of icy road conditions, especially on bridges and untreated surfaces.
The most dangerous travel conditions are expected Saturday night through Sunday night, with impacts potentially lingering into Monday as cold temperatures slow cleanup efforts. Even small delays in road treatment could quickly lead to hazardous driving conditions during peak snowfall rates.
Drivers are urged to avoid unnecessary travel during the height of the storm, prepare for extended delays, and monitor forecast updates as timing and snowfall amounts become clearer.
Commuters, students, and weekend travelers across the Philadelphia metro area should plan for significant travel disruptions and possible cancellations.
