The U.S. Northeast on Monday braced for a massive, crippling blizzard that could dump as much as three feet of snow as tens of millions of people were urged to stay home and airlines canceled thousands of flights.

Transit systems in New York, New Jersey, Connecticut and Massachusetts planned to curtail services, and several governors ordered motorists off roadways by evening in a region that is home to some 50 million people.

The National Weather Service issued a blizzard warning for New York City and surrounding areas between coastal New Jersey and Connecticut, beginning 1 p.m. EST (1800 GMT) on Monday and worsening overnight.

The weather service warned the approaching system would be a "crippling and potentially historic blizzard," with many areas along the East Coast expected to be blanketed by 12 inches to 24 inches (30-60 cm) of snow. The New York City area could be the hardest hit, with lashing winds topping 50 miles per hour (81 kph) and snowfall of three feet or more in some suburbs.

Vacationers and business travelers faced headaches as airlines canceled about 2,700 flights, according to flight-tracking service FlightAware, including nearly 700 flights at the three main airports serving New York City.

STATE OF EMERGENCY

New York Governor Andrew Cuomo declared a state of emergency and deployed National Guard troops to a number of counties in the southern part of the state as well as New York City.

N.Y. authorities said they were considering a total travel ban on main roads, starting at 11 p.m. EST (0400 GMT Tuesday).

"It could be a matter of life and death so caution is required," Cuomo said. "This is not an evening or a night to be out and about."

New York City subways, which carry 5.5 million riders daily, will run on a normal schedule until about 8 p.m., when service will be curtailed to allow subway cars and equipment to be stowed, Cuomo said at a news conference.

New York City public schools, which serve more than 1 million students, will be closed on Tuesday, New York Mayor Bill de Blasio said. Scores of other schools districts were shutting early on Monday.

Two major commuter railroads, Metro-North Railroad and Long Island Rail Road, will run normally until 11 p.m., Cuomo said.

New Jersey Governor Chris Christie declared a state of emergency, and sent all but the most essential government workers home on Monday afternoon, telling them not to return until Wednesday at the earliest. New Jersey Transit commuter trains will stop running for at least one day, beginning at 10 p.m. on Monday, he said.

"Please stay home," Christie told residents.

The governors of Massachusetts and Connecticut told residents to expect driving bans later tonight and all day tomorrow. They warned that hundreds of thousands of people could lose power, possibly for days.

"We are anticipating an historic, top-five storm, based on the snowfall," Massachusetts Governor Charlie Baker told reporters on Monday. The Boston-area transit system will be shut on Tuesday, he said. He warned that coastal parts of the state will likely suffer flooding.

At Boston's Logan International Airport, the last passenger flight was to leave around 7 p.m. EST (midnight GMT) and airlines planned to remove all planes by the day's end.

President Barack Obama, who is traveling in New Delhi, India, was briefed on the coming storm earlier on Monday, White House spokesman Josh Earnest told reporters.
