Parts of New England were preparing for a blizzard on Monday morning.

The National Weather Service issued a blizzard warning for southeastern Massachusetts, warning that 8 to 12 inches of heavy snow and wind gusts of 60 mph were in the forecast.

The service warned the storm could damage trees, cause power outages and lead to whiteout conditions, which may complicate travel. The blizzard warning expires at 7 p.m. this evening.

Snowfall totals were steadily on the rise on Cape Cod, with the National Weather Service reporting that 3.5 inches fell in Centerville, Massachusetts, in just four hours.

Other parts of Connecticut, Rhode Island, Massachusetts, Long Island and coastal New Hampshire were under less-severe winter storm warnings, though the National Weather Service was still calling for 4 to 10 inches of snow and wind gusts of up to 45 mph in those regions.

Lighter totals are forecast in Maine, New Jersey, New York and northern New Hampshire, which were under winter weather advisories. The service is calling for 2 to 6 inches of snow there.

Those advisories and warnings are set to expire tomorrow morning, according to the service.

The Weather Channel is calling the storm Winter Storm Mars.

The winter storm comes just two days after another winter storm knocked out power for at least 170,000 customers in Massachusetts, Connecticut and Rhode Island. About 5,000 customers in those states were without power as of 11 a.m. local time Monday, according to the Massachusetts Emergency Management Agency and local utility companies Eversource and National Grid.

The latest storm already led to more than 300 flight cancellations to or from Boston Logan International Airport, according to flight monitoring website FlightAware.com. Nearly 400 flights to or from the three airports that serve New York City were cancelled, the site reported.

Massachusetts governor Charlie Baker said that all non-emergency government employees in nine of the state’s 14 counties should not report to work on Monday. The Massachusetts State Police also tweeted that ferry service to Martha’s Vineyard and Nantucket had been suspended.

Separately, the National Weather Service issued blizzard warnings in parts of Iowa and Minnesota as another storm moves across the Great Plains. The service is only calling for an inch of snow, but 55 mph wind gusts could significantly reduce visibility through tonight.

“Travel is not advised in many areas,” the blizzard warning states.

The service also issued winter storm warnings in parts of Carolina and Tennessee, saying parts of the East Tennessee Mountains could see a foot of snow before Wednesday. Winter weather advisories were issued in several surrounding states, though lighter totals were expected there.

Residents of all the affected states should monitor their local forecasts.
