NEW YORK -- Following days of mild temperatures and hints of spring as the calendar approached March, winter returned to the Northeast with a bang Friday, as rain and snow drove down in sheets and winds blew at gale force, prompting dire warnings of coastal flooding, dangerous sea conditions and power outages.
"As the saying goes, March is coming in like a lion," New York Gov. Andrew Cuomo said in a news release. "I am asking for everyone to listen to weather forecasts in your community and take the necessary precautions to prepare for conditions."
The storm originated as a system of low pressure in the Great Lakes region that dumped snow on northeastern Michigan and Ohio and then rapidly intensified as it moved east, Marc Chenard, a meteorologist with the National Weather Service, said.
"It's that rapid intensification that is bringing high-impact weather," including heavy snow inland and flooding in coastal areas, Chenard said.
Forecast to hit eastern Massachusetts especially hard, the effects of the storm, which began with rain Thursday night and turned to snow Friday, were being felt up and down the Atlantic Coast on Friday, from North Carolina to Maine.
National Guard troops have been called in, schools closed, and communities urged to evacuate. More than 2,500 flights across the U.S. have been canceled, with New York-area and Boston airports the most affected, according to the flight tracking website FlightAware.

The powerful nor'easter struck the East Coast at the same time California braced for blizzards in the Sierra Nevada and floods in burned-out areas of Santa Barbara County.
In Massachusetts, Gov. Charlie Baker said at a news conference Thursday that the storm was "shaping up to be more severe than" the early January "bomb cyclone" that brought heavy snow, frigid temperatures and fierce winds to the region.
Baker, who activated National Guard troops to assist with emergency response, urged residents in historically flood-prone coastal areas to follow any evacuation orders they receive, warning that astronomically high tides combined with storm surges will prevent water from receding.
"It's possible that first responders will be unable to reach all flooded areas at peak high tide," he said. "Do not ride out the storm in your home if you are told to evacuate."
