Overview
- The National Weather Service posted blizzard warnings for New York City, Long Island, coastal Connecticut, and parts of coastal New Jersey and Delaware, including NYC’s first such alert since 2017, with more than 40 million people under winter alerts.
- Snow is expected to develop Sunday, intensify Sunday night into Monday morning, and taper by late Monday, with whiteout conditions likely near the coast.
- Forecasts call for roughly 12–18 inches in New York City, Long Island, coastal Connecticut and around Philadelphia, with 18–24 inches possible along the Jersey Shore, as coastal gusts reach 55–60 mph.
- Major transportation disruptions are likely as airlines issue waivers and Amtrak warns of adjustments, with severe impacts expected for the Monday commute and operations at major airports.
- Heavy, wet snow and strong onshore winds could cause scattered power outages and minor to moderate coastal flooding at high tide, though local totals remain sensitive to the storm track and the rain–snow line.
