A fall nor’easter dropped more than 3 inches of snow on parts of Central and Southeastern Massachusetts Wednesday night, with some areas seeing more than 5 inches, according to the National Weather Service.
A mixture of snow and freezing rain was expected to continue in most areas after midnight, the weather service said, with more rain forecast for Thursday before sunnier weather arrives heading into the weekend.
The stormy conditions Wednesday led to traffic accidents, power outages, flooding, and wind damage.
“We are expecting some more snowfall overnight,” Matt Doody, a weather service meteorologist, said in a phone interview late Wednesday.
“Now, granted the bulk of the snowfall has probably already fallen, but there will still be a little more,” he said.
By Wednesday evening, reported snowfall totals were 3 inches in Seekonk, 4 inches in Shrewsbury, 5 inches in Southbridge, and 5.6 inches in Foxborough, according to the Weather Service.
More than 300 crews were treating and plowing state roads late Wednesday night, according to the Department of Transportation, and the City of Boston said on its official Twitter feed that road crews would work through the night.
Overnight accumulation was expected to be 1 to 5 inches in the eastern part of the state, and 2 to 6 inches in Central and Western Massachusetts, said a weather service advisory posted Wednesday night.
Doody said late Wednesday that the weather service had extended its winter weather advisory to virtually the entire state, except for the Cape and islands. Such an advisory is issued when snow or ice is expected to develop.
“Any snow or ice would make driving and walking difficult” on untreated roads, the advisory said.
High winds also battered the state Wednesday, according to the weather service.
By late afternoon, it had collected reports of winds bringing down trees and wires in a number of communities, including Plymouth, Duxbury, Fairhaven, Needham, Worcester, Natick, and Taunton.
At 6 p.m., police closed the stretch of Route 3A that passes Plymouth Beach because of high surf and a storm surge that had sent ocean water over a 6-foot sea wall and across the highway.
A steady wind of 30 miles per hour with gusts up to 50 miles per hour tossed up 4-to-6-foot waves in Plymouth Harbor that easily breached the breakwater protecting fishing boats in the inner harbor.
Later in the evening, peak wind gusts of more than 60 miles per hour were reported in Plymouth, Nantucket, Martha’s Vineyard, and Fairhaven, according to the weather service.
Gusts in the high 50s were reported on parts of the Cape and in Duxbury, and a 76-mile-per-hour gust was reported off Cuttyhunk Island , south of New Bedford.
In addition to Plymouth, the fierce winds also brought coastal flooding to Nantucket, Chatham, and Quincy, the weather service said.
National Grid reported at about 10:30 p.m. that approximately 1,599 customers were without power in the state, mostly in the southeastern region, 3,089 customers without power, mostly on the south coast and the Cape and islands.
