Flight cancellations and delays continued Monday as the winter storm that tore across the United States reached the Northeast, bringing several inches of snow and coastal floods. Travel disruptions are likely, with the National Weather Service warning of hazardous driving conditions.

The storm initially formed on the West Coast days before Thanksgiving, snarling holiday travel plans. It slowly moved east over the Great Lakes region and will likely remain until Tuesday morning.

Although Boston has been spared the worst of the storm, portions of Massachusetts could see 6 to 10 inches of snow. Simon Rios with member station WBUR told NPR's Newscast Unit that state transportation officials deployed more than 3,500 plows to remove snow.

Flood warnings are in effect for coastal Massachusetts, with 1 to 2 feet of inundation during high tide. Weather officials are saying to avoid oceanside areas and to watch out for erosion along dunes and beaches.

The storm's arrival in the New York metropolitan area coincided with a Sunday-night football game in New Jersey. New York Gov. Andrew Cuomo declared a state of emergency in seven counties and deployed the National Guard to assist with cleanup.

Residents in New York City face as little as 2 inches of snowfall, according to the National Weather Service. However, Mayor Bill de Blasio warned that it could easily see more than that projection.

"As we have learned with previous storms, they can come faster and can be larger than originally projected," de Blasio said at a news conference Monday. "The fact that we got 5 to 8 inches projected for some parts of the city should make everyone quite aware that number could go up and could go up quickly."

Areas in New England will face more extreme conditions. Southwest Maine and New Hampshire will get a brief respite from heavy snow during the day but it is slated to resume Monday night with accumulations of 3 to 7 inches. In some areas, more than 11 inches of snow has blanketed roads and cities.

Meanwhile, on the West Coast, inclement weather continues as highway authorities are requiring cars to install snow chains on a major interstate. Several portions of the Sierra Nevada received more than a foot of snow overnight. The storm is expected to continue into the upcoming weekend, bringing heavy precipitation to surrounding regions.

The effects of the storm have been felt nationwide. On Sunday, nearly 1,000 flights across the U.S. were canceled and more than 8,700 were delayed, according to FlightAware.

While the Thanksgiving rush has passed, travel plans are still hitting a snafu. As of 12:15 p.m. ET Monday, nearly 460 U.S. flights had been canceled and more than 2,300 delayed.
