The third nor'easter in two weeks lashed SouthCoast on Tuesday with more than a foot of snow, causing power outages and knocking down trees and power lines.

Acushnet Fire Chief Kevin Gallagher said homes on Third Avenue and Hamlin Street, the same neighborhood, were damaged when trees crashed into them. "We were responding to Third Avenue when a resident waved us down and said a tree had crashed through a roof on Hamlin Street," he said. Both incidents happened around 11:40 a.m.

A tree struck a garage and then a house on Third Avenue and there was a 4-foot branch protruding through the kitchen ceiling, he said. The house on Hamlin Street suffered "significant damage" to the roof. There were no injuries, although both homes were occupied when the trees fell. "We were very lucky in both cases," he said.

The power has been shut off to both homes and the residents will be displaced at least for Tuesday night, he said.

The damage came right in the middle of an intense period for the Acushnet Fire Department. The heavy, wet snow extended an ambulance run from Fairway Drive, Acushnet, to St. Luke's Hospital, New Bedford, from 7 or 8 minutes to 30 minutes. On the trip back to Acushnet, the ambulance got stuck in the snow and had to be freed by the New Bedford Department of Public Infrastructure.

"Both our ambulances have 4-wheel drive and even with that they could not keep up with road conditions," he said. "The period of 10:15 (a.m.) to 11:45 (a.m.) was the most intense period of the storm for us." 

The downed trees and tree limbs kept the Acushnet DPW busy, said Police Chief Michael Alves.

According to the National Weather Service in Taunton, 13.5 inches of snow was recorded in Acushnet at about 4 p.m. and 13.3 inches of snow was reported in Westport about 4:30 p.m. Bill Simpson, a meteorologist with the National Weather Service in Taunton, said SouthCoast received between 10 and 14 inches of snow with some parts receiving more.

Elsewhere across SouthCoast, the wet, heavy snow that knocked down trees and blocked roadways and took down power lines was the story. However, in most communities, accidents were at a minimum as residents stayed home.

"Apparently, people have heeded the warning and stayed off the roads," said Dartmouth Detective Kyle Costa, a spokesman for the Police Department. "Traffic is very, very light."

In Dartmouth, many of the fallen tree limbs also brought down power lines with them, causing "sporadic outages," he said.

But while vehicular crashes were at a minimum, power went out again about 12:30 p.m. to the traffic lights at Faunce Corner and State roads near the Dartmouth Mall.

Westport Detective Jeff Majewski said two trees came down on Route 88 in the Briggs Road area and caused the state highway to be temporarily shutdown about 9 a.m. The incidents occurred on the north and south sides of Route 88.

"We have probably had a dozen" trees come down in Westport across roadways, he said.

Mother Nature and first responders were in an apparent foot race in Fairhaven at one point with trees and limbs falling and blocking roadways and power lines coming down, said Lt. Kevin Kobza, whose promotion from sergeant became official Monday morning.

"We can't even get ahead of it. We're just trying to keep up with it," Kobza said. 

About 9:40 a.m., a live wire with flames came down and was across a homeowner's driveway on Spring Street, he said. The wire was covered with snow and concealed from view so police dispatched an officer there until Eversource could deactivate the line.

New Bedford Fire Chief Michael Gomes said they were straight-out responding to downed power lines on Tuesday. Between 8 a.m. and 2 p.m., he said the NBFD had over 100 calls for service and 90 percent of those were for downed power lines.

Also, firefighters responded to two incidents where people were trapped in elevators when power went out, including one at Melville Towers.

"Just another day at the office, run of the mill storm," he said, praising the hard-working men and women of the NBFD.
