Philadelphia, Pennsylvania – Emergency managers across the Mid-Atlantic are monitoring a developing coastal system that could bury parts of Pennsylvania, New Jersey and Delaware under up to 3 feet of snow if it rapidly intensifies into a bomb cyclone early next week.
According to the National Weather Service, computer guidance shows a low-pressure system tracking up the East Coast that may undergo bombogenesis, defined as a pressure drop of at least 24 millibars in 24 hours. If that strengthening occurs near the shoreline, snowfall rates could exceed 2 to 3 inches per hour along the Interstate 95 corridor from Washington to Philadelphia and into central New Jersey.
Philadelphia, Trenton, Newark and Wilmington would be positioned for the heaviest snow if the storm tracks just offshore. A slight shift east would cut totals dramatically, while a track closer to land could bring widespread 18- to 36-inch accumulations and wind gusts topping 50 mph. Whiteout conditions and coastal flooding would become significant concerns, especially in low-lying communities along Delaware Bay and the Jersey Shore.
Residents should prepare now by checking generators, stocking supplies and limiting travel plans. Forecast confidence will increase over the next 24 to 48 hours, and watches or warnings could be issued quickly if the storm organizes as projected.
