Winter Storm Neptune pounded Massachusetts Sunday with heavy snow, high winds and bone-chilling temperatures. By Sunday afternoon, most of the snowfall had subsided in Boston and surrounding areas, but state and city officials were warning people to stay inside and off the roads because of the dangers posed by high winds, blowing snow and frigid temperatures.

Massachusetts State Police Sunday evening were reporting several car accidents outside of Boston. On I-95 Southbound west of the city, past Exit 27 in Waltham, police received word of , with initial accounts putting 20 cars in the pileup. A 4 p.m. update confirmed that the crash victims sustained minor injuries only and that three lanes of the highway had been reopened.

Details began to emerge of another accident, north of the city, on Route 128 Southbound at the intersection of Route 114. Massachusetts State Police say no one was injured, but that the left lane is currently closed.

Total today reached more than a foot in Boston — on top of the 6 feet of standing snow already blanketing some places — during the city’s third-snowiest winter on record. Other parts of the state have seen almost 2 feet. Acushnet, near Buzzards Bay in the central part of the state, received 22 inches, and Bridgewater and New Bedford, each got 20, trapping several cars Sunday morning on impassable roads in New Bedford. At least half a dozen other Massachusetts cities reported snowfall of 17 inches or more.

Tonight dropping temperatures and high winds could be a factor. “The primary concern across New England is the wind, which will remain strong through the night,” we reported in our . “This will lead to areas of blowing snow and dangerously low wind chills.” Winds could get up to 40 mph in some places.

The wind and cold are forecasted to continue into Monday. “The wind is going to pick up and then you got the cold air,” said meteorologist Reynolds Wolf, reporting from Boston for The Weather Channel. “Like an unwanted neighbor that comes over and visits, it’s going to stick around for quite awhile.”

As the storm recedes, Massachusetts Gov. Charlie Baker said concerns will shift toward keeping exhaust vents clear and removing snow from roofs to prevent collapses. There have been a number reported throughout the state, including a partial roof collapse of an apartment complex in Newburyport, Massachusetts, Sunday afternoon. The Boston Globe offers some guidance about .

Winter Storm Neptune comes on the heels of an almost three-week snow siege that has smashed records in parts of New England, including Boston and Worcester. Much of that snow is still on the ground due to a prolonged cold snap, and that snow will compound the misery from this storm as Neptune’s winds blow not only the new snow, but snow already on the ground. “We’re about at 7 feet of snow in three weeks in the city of Boston,” said Boston Mayor Marty J. Walsh. “This is historic. We’ve never seen this type of snow.”

Transportation officials in Boston had taken precautions in advance of the snow. By Sunday evening, nearly had been canceled traveling into and out of Boston’s Logan International Airport, according to FlightAware. The canceled all rail, bus and ferry service in the Boston area on Sunday and planned to offer limited services Monday, though as of Sunday evening the MBTA had not designated which lines and services would run.

MassDOT has more than 3,300 snow crews out Sunday for plowing and clearing the roads, Transportation Secretary Stephanie Pollocks said. She urged residents to stay off the roads, even once snowing stopped. The City of Boston put in place a snow emergency and parking ban until further notice. The city also ordered the reconfiguration of several streets to improve public safety, temporarily making some two-way streets one way. The state of Massachusetts itself had not implemented a travel ban because the storm’s effects vary across the region, according to Baker.

With the weather showing little love on Valentine’s Day, Baker on Friday proclaimed “” in Massachusetts and encouraged people to celebrate the holiday by buying gifts and dining out all next week. Business groups said weather-related travel woes have cut into sales by up to 80 percent for some restaurants and retailers leading up to Valentine’s Day, a holiday that usually generates about $500 million in business.

School superintendents in Massachusetts were spared the decision of whether to order more snow days, as school vacation was already scheduled for next week.
