Philadelphia, Pennsylvania —
Dangerously cold temperatures and biting winds are continuing across eastern Pennsylvania, New Jersey, and Delaware, creating hazardous conditions for travel and outdoor exposure through Monday morning.
According to the National Weather Service in Philadelphia/Mount Holly, wind chills ranging from -10 to -30 degrees are expected to persist through early Monday as Arctic air remains locked over the region. The combination of very cold air and gusty winds significantly increases the risk of frostbite and hypothermia, especially for those outdoors for extended periods.
An Extreme Cold Warning remains in effect for the southern Poconos, including Carbon and Monroe counties in Pennsylvania, until 10 a.m. Monday. Elsewhere across the region, a Cold Weather Advisory continues through Monday morning.
Travel impacts are possible along major corridors including Interstate 95, Interstate 76, Interstate 80, the New Jersey Turnpike, and U.S. Route 1, where vehicle breakdowns can quickly become dangerous in the extreme cold. Road conditions are generally dry, but exposure risks rise sharply if motorists become stranded.
Forecasters note that the coldest wind chills are expected overnight and early Monday morning, particularly in open and elevated areas where winds remain strongest. Even brief exposure of bare skin can lead to frostbite in as little as 10 to 20 minutes.
Residents are urged to dress in multiple layers, cover exposed skin, limit time outdoors, and ensure pets are brought inside. Drivers should keep winter emergency kits in vehicles, including blankets, extra clothing, food, and a charged phone.
Conditions are expected to slowly moderate as the region moves into midweek, but bitterly cold conditions will dominate through Monday morning.
The alert is especially relevant for early-morning commuters, commercial drivers, outdoor workers, and first responders, who face the greatest exposure risks.
Officials encourage continued monitoring of forecasts and strict adherence to cold-weather safety guidance until temperatures improve.
