Blizzard warning go into effect in New York City starting at 2 p.m. Sunday, and this storm is expected to have major impacts across all five boroughs. Heavy snow and powerful winds will move in Sunday afternoon and continue into Monday afternoon. Conditions will get worse quickly Sunday evening, with travel becoming dangerous or impossible overnight and into Monday morning.

Snow may start lightly Sunday morning and be even mixed with light rain at times, but the heaviest snow will fall late Sunday and Sunday night. Snowfall rates could reach 1 to 3 inches per hour, making it difficult to see and nearly impossible to keep roads clear. Current projections suggest 15 to 20 inches of snow in New York City, with the potential for even higher totals if heavier snow bands stall over the area. Roads will become snow-covered Sunday evening as temperatures drop below freezing, and untreated surfaces will turn icy.

Strong winds will add to the danger. Gusts in New York City could reach 45 to 55 miles per hour Sunday night into Monday morning. These winds will blow snow around, creating whiteout conditions at times. Downed tree limbs and scattered power outages are possible, especially as heavy, wet snow weighs on branches and power lines early in the storm. Residents should be prepared for difficult travel, limited visibility, and potential service disruptions.

In addition to snow and wind, coastal flooding is a serious concern, especially during Sunday night’s high tide. Parts of coastal neighborhoods, including areas around New York Harbor and Jamaica Bay, could see moderate flooding. Some shoreline erosion and localized flooding of low-lying roads are possible. Minor flooding may continue into Monday’s high tide cycle.

Looking ahead, temperatures will stay cold early in the week before rising into the 40s later in the week. That will begin melting the snow, but freezing temperatures at night could cause melted snow to refreeze, creating icy sidewalks and roads. New Yorkers should prepare now, avoid unnecessary travel during the height of the storm, and follow official safety guidance.
