A storm developing off the eastern U.S. may bring 4 inches (10 centimeters) of snow to Washington while dusting New York and hitting hardest at Cape Cod, eastern Maine and the Canadian Maritimes.
Two systems about to combine in the Atlantic will form a powerful storm that will bring blizzard conditions to Cape Cod in Massachusetts and eastern Maine overnight before moving on to Canada, said Rob Carolan, founder of Hometown Forecast Services Inc. in Nashua, New Hampshire.
“There will be a little snow in D.C., a little snow in Baltimore, but the real jackpot is east of the Cape Cod Canal,” Carolan said. “Nova Scotia and the eastern Canadian Maritime Provinces are going to get buried.”
A winter weather advisory stretches from southern New Jersey to eastern Tennessee. Washington and Baltimore may receive 2 to 4 inches of snow throughout the day, said Amy Bettwy, a National Weather Service meteorologist in Sterling, Virginia. New York City may get about an inch by tomorrow, said Lauren Nash, an agency meteorologist in Upton, New York.
The first of the two weather systems is coming up from the south and the second is crossing the Midwest, Carolan said. The snow in New York will be caused by the second one as it moves into the Atlantic, he said. Once the two parts come together later today, barometric pressure will drop drastically and the storm will strengthen significantly, a process meteorologists refer to as a bomb.
“It will be the classic definition of a bomb,” Carolan said.
Warnings of hurricane-force winds have been issued for ships at sea from Maine to the North Carolina-Virginia line, the weather service said. Waves may grow to 42 feet and winds could reach 80 miles (129 kilometers) an hour in the Atlantic.
A blizzard watch was posted for Cape Cod and a blizzard warning for the eastern tip of Maine. Blizzard warnings have also been issued for areas of New Brunswick, Prince Edward Island and Nova Scotia by Environment Canada.
Parts Nova Scotia may receive 20 inches of snow, be raked by wind gusts of 99 mph and experience coastal flooding tomorrow, the weather agency said.
As the storm passes the Massachusetts coastline, Boston may get 1 to 3 inches overnight, while 4 to 6 inches may fall on its southern suburbs and 10 inches or more on eastern Cape Cod and Nantucket, Carolan said.
Behind the storm, temperatures are expected to rise throughout the Northeast. Washington’s high is forecast to reach 65 degrees later this week, while New York may get to 57 and Boston 55, the weather service said.
