A major winter storm has swept through New Jersey and the northeastern United States, bringing heavy snow, sleet, and freezing rain, resulting in hazardous travel conditions. New Jersey declared a state of emergency with widespread travel restrictions, including bans on commercial vehicles on major highways such as I-78, I-80, I-280, I-287, and Route 440, to ensure safety. The storm has caused significant disruptions, with snow totals expected to range from 4 to 8 inches in some areas, but ice accumulation is now the primary concern due to a warm layer of air causing freezing rain and sleet. Authorities warn drivers to avoid unnecessary travel, slow down, and exercise caution, especially on bridges and ramps. Emergency services are on alert, and residents are advised to prepare emergency kits. The storm's forecast has been revised, with snowfall totals reduced and ice risks increased, particularly in Hunterdon, Somerset, and northern Mercer counties. The storm is also affecting neighboring states, causing airport cancellations, road closures, and delays across Pennsylvania, Maryland, New York, and Connecticut. Temperatures are expected to remain cold through the week, with strong winds and additional cold fronts bringing further challenges. Overall, the storm has created a dangerous winter mess with widespread impacts on transportation and safety.
