Philadelphia, Pennsylvania – Travel along the Mid-Atlantic coastline could deteriorate rapidly after 9 p.m. Sunday as heavy snow bands and 50+ mph wind gusts begin sweeping into the I-95 corridor from Pennsylvania through Maryland.
According to the National Weather Service and NOAA’s Weather Prediction Center, a strengthening coastal storm will develop near the Mid-Atlantic late this weekend before intensifying offshore Sunday into Monday. Moderate winter storm impacts are possible from 7 p.m. Sunday through 7 p.m. Tuesday, with the heaviest effects focused along coastal New Jersey, Delaware, eastern Pennsylvania and central Maryland.
In the Philadelphia metro, snowfall rates may approach 1 inch per hour between midnight and 6 a.m. Monday, quickly covering I-95, I-76 and portions of the Pennsylvania Turnpike. Slippery bridges and reduced visibility below one mile could slow the Monday morning commute. PennDOT crews are expected to pretreat major highways, but drivers should plan for delays.
Farther south, Baltimore and Annapolis face strengthening northeast winds gusting up to 55 mph by early Monday afternoon. Those winds may impact high-profile vehicles along I-95, I-695 and U.S. 50 while increasing the risk of scattered power outages near the Chesapeake Bay shoreline. Minor tidal flooding is possible in low-lying sections of downtown Annapolis around high tide Monday.
In Wilmington and southern New Jersey, including Atlantic City, 2 to 4 inches of snow combined with blowing snow may create slick conditions along Route 13 and the Garden State Parkway.
Residents should complete travel before late Sunday evening, secure outdoor items, and charge devices in case of outages. Confidence in storm development remains high, but small track shifts could alter snowfall totals. Additional advisories are likely as the system strengthens offshore.
