A subtropical storm could make its way to New England this weekend

In a fitting farewell to a summer that ranked as the second rainiest on record in Boston, a soggy weekend is in store for Massachusetts.

This time, it’s a subtropical storm that’s expected to drench Southern New England on Saturday, forecasters said.

A low-pressure system that’s expected to gain “tropical characteristics” as it moves over the Atlantic Ocean will intensify over the Carolinas on Friday and head up the coast to New England on Saturday, said Kyle Pederson, a meteorologist with the National Weather Service in Norton.

“We’re likely looking at a washout for most of Southern New England on Saturday,” Pederson said. While there’s some uncertainty in the forecast, the system could bring 1 to 2 inches of rain on Saturday afternoon, with Southeastern Massachusetts and Rhode Island expected to see the most precipitation, Pederson said.


There may be some lingering showers on Sunday, when there’s about a 30 percent chance of rain, Pederson added.

Flooding is the main concern as a result of the storm, Pederson said, although Boston could also see wind gusts of 15 to 20 miles per hour with gusts of 20 to 30 miles per hour over the waters.

“We’ll be keeping a close eye for flooding with all the rain we’ve gotten this summer already,” Pederson said.

The forecast is expected to become clearer in the next couple of days as the system gets closer, forecasters said.

The rainy weekend will cap a summer of wild weather in the region that put millions of people under weather warnings and brought multiple tornadoes, the threat of a hurricane, and more than 20 inches of rain to Boston.
