Zohran Mamdani orders NYC travel ban as 54 million face blizzard

More than 50 million people across the U.S. Northeast are under blizzard or winter storm warnings as a rapidly strengthening nor'easter barrels up the I-95 corridor, prompting New York City Mayor Zohran Mamdani to declare a state of emergency and impose a citywide travel ban from 9:00 p.m. Sunday until 12:00 p.m. Monday. City officials said schools will be canceled and streets, highways and bridges will be shuttered to nonessential traffic, with narrow exemptions for emergency and critical service workers.

Forecasters put the tally at about 35 million people under blizzard warnings and another 19 million under winter storm warnings, a combined 54 million under official alerts. The National Weather Service said the storm's low center is expected to develop late Sunday afternoon through the evening as it gathers strength offshore near Delaware, Maryland and Virginia, then push heavy snow, damaging winds and coastal flooding into the densely populated Northeast.

Cody Snell, a meteorologist at the NWS Weather Prediction Center, said: "While we do get plenty of these nor'easters that produce heavy snow and strong impacts, it's been several years since we saw one of this magnitude across this large of a region in this very populated part of the country."

Forecasts show widespread snowfall of 12 to 24 inches across much of the I-95 corridor. New York City metro forecasts center on 18 to 24 inches, though some forecasts cite a slightly wider 12-to-24-inch range depending on the final track. Snowfall rates could spike to 2 to 3 inches per hour at times, and wind gusts are expected to reach 50 to 70 mph in some coastal and exposed areas, creating life-threatening whiteout conditions and near-zero visibility. Temperatures will fall into the 20s Fahrenheit in many spots, and forecasters warn of coastal flooding for beaches and low-lying areas from the Mid-Atlantic into New England and the Canadian Maritimes.

Transportation disruptions are already substantial. Flight tracking firm FlightAware reported more than 3,500 U.S. flight cancellations for Sunday alone and cited more than 7,400 cancellations through Monday as carriers preemptively grounded operations. The New York City travel ban applies to all vehicles, officials said, including cars, trucks, scooters and e-bikes, and is intended to keep roadways clear for emergency responders and plows.

State officials in Connecticut, Delaware, New Jersey and Rhode Island declared states of emergency, and New York and Massachusetts have issued similar restrictions as the storm approaches. Blizzard warnings stretch from Cape Charles, Virginia, north through the I-95 corridor from Philadelphia to Boston and up to coastal Maine; entire states including Delaware, New Jersey and Rhode Island are in some form of blizzard or winter advisory.

Emergency managers and utility officials warned that the weight of heavy, wet snow combined with extreme winds raises the risk of widespread power outages. Businesses, public agencies and residents were urged to complete storm preparations immediately: secure generators and fuel, charge devices, stock essential supplies and avoid travel during the peak of the storm.

With millions facing paralyzed commutes and thousands of flights already canceled, the nor'easter presents an immediate economic hit to travel, logistics and local commerce in a densely populated region. Officials said updates will follow as the storm center develops offshore and the timing and intensity of impacts become clearer.
