Philadelphia, Pa. – Drivers across southeastern Pennsylvania faced dense fog Wednesday morning, reducing visibility to under a quarter mile on some roads. With storms expected Thursday and Friday, commuters are advised to prepare for slower travel and rapidly changing conditions.
Current Weather Conditions
The National Weather Service in Mount Holly reported locally dense fog across Delaware, New Jersey, and southeastern Pennsylvania. Motorists were warned to use low beam headlights and reduce speed during early commutes. I-95, Route 1, and other major corridors into Philadelphia experienced the heaviest impacts, though visibility is expected to improve later in the day.
Rain and Thunderstorm Forecast
Philadelphia faces a 70–80% chance of showers and thunderstorms Thursday, with storms persisting into Friday. The heaviest rainfall is expected late Thursday night through midday Friday, which may slow both morning and evening commutes.
- Rainfall totals: Likely under 1 inch
- Risks: Localized downpours could trigger brief street flooding
Travel Impacts
Commuters heading into Center City, Cherry Hill, or along I-76 should allow extra travel time and avoid low-lying roads prone to pooling water. SEPTA and NJ Transit riders may experience delays if storms occur during peak hours.
“Drivers should exercise caution, especially during early morning and evening commutes. Low visibility combined with wet roads can increase accident risks,” warned local authorities.
