Hundreds of flights cancelled as winter storms batter parts of the US

Hundreds of flights have been grounded across the US from a pair of winter storms that left more than a foot of snow in New York's Hudson Valley and sparked blizzard warnings across the Great Plains.

The first storm was still bringing heavy snow on Sunday across Boston and New England, the National Weather Service said. Regions to the north and west of New York City, including the upper Hudson River Valley, received from 6 to 12 inches of snow.

"Poughkeepsie, they picked up a foot," said Greg Carbin, branch chief of the US Weather Prediction Center. "Orange County, New York, they got a solid foot there. Port Jervis got 13 inches." New York City was spared the worst of the weather, with Manhattan's Central Park getting mostly rain.
