A nor’easter is expected to bring 1.5 to 3 inches of rain and maximum wind gusts of 45 to 60 miles per hour across much of eastern Massachusetts on Saturday, according to forecasters from the National Weather Service in Norton.
The storm is expected to last through the day Saturday and depart the region on Sunday morning.
“The main impacts we’re watching are heavy rain, the strong winds, and the potential for minor coastal flooding,” according to Lenore Correia, a meteorologist with the service. “That’s our big message that we’re trying to convey to the public.”
Correia said the nor’easter is “slightly related to the same energy” from Hurricane Willa, which made landfall in western Mexico earlier this week as a category 3 storm.
The flooding will likely hit typical spots, such as Morrissey Boulevard, which she said “floods quite often if the tides are right and if there’s any kind of strong swell.”
Maximum wind gusts of 55 to 60 miles per hour are in the forecast for Gloucester, Cape Cod, and the islands. Boston and Plymouth are expected to see wind gusts of 45 to 55 miles per hour.
“It’s definitely possible that some power could get knocked out, and there’s also the potential for some tree damage, things like that,” she said.
A high wind warning is in effect until noon.
