A nor’easter is set to continue to batter the Massachusetts coastline Thursday into Friday, bringing “strong to damaging winds,” plus rain and the potential for coastal and inland flooding with it, according to local meteorologists.

The National Weather Service issued a wind advisory for the Massachusetts coastline, as well as a high wind warning for Cape Cod and the Islands until 6 a.m. Friday. The Cape, Islands, and southeast Massachusetts are also under a flood watch until Friday morning, while the Boston coastline down through the South Shore are under a coastal flood advisory from 9 a.m. until noon Thursday, and from 9 p.m. Thursday until 1 a.m. Friday.

“Today should be the worst day of rain and wind, overall, in Southern New England,” meteorologist Matt Noyes of NBC Boston said. “Rain will spread west off the ocean and winds will reach their peak speeds this evening.”

Eastern and southeastern Massachusetts, extending to the Cape and Islands, could see minor to moderate coastal flooding, the service said. It predicts about a two-foot surge during high tide, plus waves between 15 and 25 feet. This could mean one to two feet of water inundation for shoreline roads.

Southeast Massachusetts, plus the Cape and Islands, could also see some inland flooding due to an additional 3 to 6 inches of rain predicted. With Wednesday’s rain factored in, the storm total could be “upwards of 8 inches,” the service said.

“Bands of rain will continue to pivot inland from the ocean storm, which was centered almost 200 miles SSE of Nantucket,” the service said on Twitter. “Heaviest rain will affect SE MA, esp Cape/Islands where another 2-4″ is expected.”

The same areas are also susceptible to strong and potentially damaging winds. The maximum sustained winds could clock between 20 and 40 miles per hour with maximum gusts between 40 and 60 miles per hour. The wind is supposed to be its strongest Thursday into Thursday night; it’s supposed to die down on Friday into Friday evening, according to the service. Boston could see gusts at 35 to 40 miles per hour.

“At present, Nantucket is a top gust at 58mph at the Great Harbor Yacht Club, but we’re currently gusting to 51mph at Vineyard Haven, 45 at Wellfleet & 44 at Duxbury,” Noyes said just before 8:30 a.m. Thursday.

“WIND will be the biggest issue today,” Shiri Spear, a meteorologist with Boston 25, said. “Tree damage & scattered power outages are possible, mainly at the coast & southeast with gusts 50-60 mph.”
