Winter storm Juno news update: New York, Boston Storm to drop up to 3 feet of snow, winds up to 65 mph

NEW YORK -- The first snowfall of a potentially "historic" and "life-threatening" blizzard began Monday Morning in New York City. Winter storm Juno is expected to drop up to three feet of snow from New York to Maine, freezing rain and wind gusts of up to 65 mph, and either cancel or delay all flights going to and from the mid-Atlantic East Coast.

The National Weather Service (NWS) issued a blizzard warning for New York City and surrounding areas beginning 1 p.m. EST on Monday. The peak impact of the storm should be from Monday night into Tuesday, and the blizzard should taper off Tuesday night.

New York City Mayor Bill de Blasio urged New Yorkers to prepare their homes for the nor'easter early and not to travel at all during the storm.

"I want everyone to understand that we are facing – most likely – one of the largest snowstorms in the history of this city," he said. "Prepare for something worse than we have seen before."

New York Governor Andrew Cuomo urged people to work from home, saying the city's bus and subway systems could be closed ahead of Monday's evening commute, along with the Metro North Railroad and the Long Island Rail Road as well as other commuter rail services.

Airlines have also prepared for winter storm Juno, canceling over 2,000 flights so far.

Delta Air Lines has canceled at least 600 flights, while United Airlines will eliminate all Tuesday flights at airports in New York, Boston and Philadelphia. The carrier will begin limiting operations on Monday night at Newark, LaGuardia and John F. Kennedy airports in the New York area, a spokeswoman said.

Southwest Airlines has canceled more than 130 of 3,410 flights scheduled for Monday, and American Airlines said it expected "quite a few" flights to be affected.

Philadelphia public schools as well as Catholic schools will close at noon on Monday. In New York, de Blasio said school children could probably expect to have Tuesday off.
