NEW YORK — Cities and towns along the East Coast scrambled to prepare for a bout with heavy snow and damaging winds after forecasters issued blizzard alerts for communities from Maryland to Massachusetts.
The National Weather Service warned that once the storm intensifies Sunday it could prove significantly more severe than projections made just a few days ago.
The weather service said 1 to 2 feet (about 30 to 61 centimeters) of snow was possible in many areas as it put out blizzard warnings for New York City and Long Island, Boston and coastal communities in New Jersey, Connecticut, Delaware, Maryland, Rhode Island and Massachusetts. Flooding was also possible in parts of New York and New Jersey, it said.
''While we do get plenty of these nor'easters that produce heavy snow and strong impacts, it's been several years since we saw one of this magnitude across this large of a region in this very populated part of the country,'' said Cody Snell, a meteorologist at the service's Weather Prediction Center.
Snell said the storm would arrive Sunday morning in areas around Washington before stretching toward Philadelphia and New York City and reaching Boston in the evening.
Some of the heaviest snow was projected to fall overnight Sunday into Monday.
The weather service said the storm could begin as rainfall in some places before worsening. Some of the heaviest snow is projected to fall overnight Sunday, with as much as 2 inches (5 centimeters) of snow per hour at times in some areas, before tapering off by Monday afternoon.
The weather service warned that the storm, with gusts up to 55 mph (80 kph), could cause whiteout conditions that ''will make travel treacherous and potentially life-threatening. The strong winds and weight of snow on tree limbs may down power lines and could cause sporadic power outages.''
