A powerful late-season winter storm is set to strike the East Coast, placing nearly 30 million people under blizzard warnings and threatening to disrupt travel, power systems, and daily life across several major cities.

Forecasters say the storm will bring heavy snowfall, strong winds, and dangerously low visibility beginning Sunday and continuing into Monday. Areas from New York City to parts of New England and coastal New Jersey are expected to face the most severe conditions.

Meteorologists describe the system as one of the most significant winter storms in years for densely populated parts of the Northeast. Officials warn that the combination of heavy snow and sustained winds could create whiteout conditions, making travel extremely dangerous or even impossible in some areas.

New York City Braces for Major Snowfall

New York City could see some of the worst impacts. Weather officials are forecasting between 12 and 18 inches of snow in the metropolitan area, with higher totals possible in surrounding regions. This marks the first time in nearly a decade that the city has been placed under a blizzard warning.

City leaders are urging residents to remain indoors and avoid unnecessary travel. Hundreds of salt spreaders have been deployed, and thousands of sanitation trucks are being converted into snowplows. Officials are also recruiting temporary workers to help clear sidewalks once the storm passes.

New York Governor Kathy Hochul declared a state of emergency ahead of the storm and activated members of the National Guard to assist with emergency response efforts.

Emergency Declarations Across the Region

New Jersey has also declared a state of emergency as forecasters predict severe blizzard conditions statewide. Residents have been advised to stay off roads from Sunday through Monday unless travel is absolutely necessary.

Parts of southern New England are also under blizzard warnings for the first time in several years. Boston and surrounding communities are expected to experience intense snowfall Sunday night into Monday afternoon, along with strong gusts and reduced visibility.

Rapidly Strengthening Storm System

Weather experts say the storm intensified quickly after earlier forecasts suggested it might be less severe. Current projections indicate that many areas could receive between one and two feet of snow, especially in coastal and northern sections of the Northeast.

Snowfall rates could reach one to two inches per hour during peak periods, with even heavier bursts possible overnight Sunday. Winds between 25 and 35 miles per hour are expected, creating blowing snow and hazardous conditions.

In addition to snow, some coastal regions may face minor flooding due to a combination of strong winds and precipitation. Downed tree limbs and scattered power outages are also possible because of heavy snow accumulation.

Travel Disruptions Widespread

Air travel has already been significantly impacted. Airlines have cancelled hundreds of flights scheduled for Sunday and Monday, particularly at major airports in New York City and Boston. Carriers are offering flexible rebooking options as they monitor the storm’s path.

Flight tracking services report more than 1,000 cancellations on Sunday alone, with additional cancellations expected into Monday. Passengers traveling through the Northeast are being encouraged to check flight statuses before heading to airports.

Officials in coastal cities such as Atlantic City have warned residents and visitors about potential flooding in low-lying neighborhoods. Emergency managers caution that snow-covered floodwaters could be difficult to see, increasing the risk of accidents.

Dangerous Conditions Expected Through Monday

Forecasters say conditions will likely worsen Sunday afternoon as colder air moves into the region. Rain in some areas could quickly change to heavy snow, leading to rapid accumulation overnight.

Authorities are urging residents to prepare emergency supplies, charge electronic devices, and avoid unnecessary travel until conditions improve. The storm arrives just weeks after another system left lingering icy conditions across parts of the Northeast.

With millions in its path, this winter storm is expected to be one of the most disruptive weather events of the season. Officials say staying off roads and following local emergency guidance will be critical in minimizing risks.
