New York City, eastern New Jersey and western Long Island were the hardest hit by the storm, which unleashed powerful winds and dumped up to 29 inches (74 cm) of snow in some parts, the U.S. National Weather Service said.
JFK International and other New York-area airports were closed on Sunday evening and expected to reopen on Monday afternoon, the Federal Aviation Administration said. Some travelers slept in airport terminals, while others sat on grounded planes.
Amtrak passenger rail service between New York and Boston was suspended over the weekend but expected to resume on a limited basis early on Monday.
“They (the trains) would run on the hour but not as many as would run on a normal weekday,” Amtrak spokesman Cliff Cole told Fox News. He added that full service could possibly be restored on Tuesday if the snow stopped.
At least 2,000 flights were canceled on Sunday.
Delta Air Lines (DAL.N) canceled about one-sixth of its flight schedule, and American Airlines (AMR.N), JetBlue Airways (JBLU.O) and Continental Airlines canceled roughly 265 flights each and United Airlines 110, airline representatives said.
The storm, the first widespread blizzard of the season, hit as Americans were returning to work after one of the busiest travel weekends of the year.
The National Weather Service issued blizzard warnings from Maine to New Jersey with winter storm warnings for nearly the entire East Coast.
Six states declared a state of emergency.
