More than 40 million people were under weather warnings in the northeastern United States on Monday, as a winter storm dumped shin-deep snow and officials in New York enforced a citywide travel ban. The so-called "Nor'easter" pummeled the region overnight, disrupting flights and leaving hundreds of thousands of homes and businesses without power.

New York Mayor Zohran Mamdani ordered nonessential drivers off the road until midday Monday and shut down schools. Authorities in neighboring New Jersey and Rhode Island issued similar travel restrictions.

The National Weather Service said snowfall would ebb overnight, but warned that strong winds would still create blizzard conditions in some areas. As of 4:00 pm (2100 GMT), more than 5,600 flights in or out of the United States had been canceled and hundreds more delayed, according to tracking service FlightAware.

New York's three major airports as well as Boston Logan Airport saw the most cancellations. Rhode Island T.F. Green International Airport registered almost three feet (32.8 inches, or 83 centimeters) of snow by Monday lunchtime – a record-shattering toll for the state.
