Situation
The Massachusetts Emergency Management Agency (MEMA) is monitoring two weather events with the possibility of impacting the New England region during the next few days.
Severe Weather:
The National Weather Service (NWS), in conjunction with the MEMA Agency Meteorologist, has forecast another round of showers and thunderstorms, which have been occurring throughout the day, and is predicted to occur through late tonight. A widespread one to two inches of rain are forecast, although localized amounts up to four inches are possible. Tornado warnings which were issued in portions of Bristol, Norfolk, and Plymouth Counties have since expired, but MEMA continues to monitor for any potential impacts.
Lingering light showers over eastern Massachusetts will shift offshore Thursday morning as drier weather returns to the region for Thursday afternoon into Friday.
Hurricane Lee:
As of 5pm EST, Hurricane Lee was located 380 miles south-southwest of Bermuda with maximum sustained winds of 105 mph. Slow weakening is forecast during the next few days, however, Lee is likely to remain a large and dangerous Hurricane into the weekend.
Hurricane and tropical storm watches issued for much of coastal new England. There is the potential for life-threatening storm surge flooding in portions of southeastern Massachusetts, including Cape Cod and Nantucket, late Friday and Saturday. Tropical storm conditions are possible over a large portion of the coast including Cape Cod, Nantucket, and Martha’s Vineyard.
From Friday night through Saturday night, Lee is expected to produce rainfall amounts of 1 to 4 inches, across portions of eastern New England. This could produce localized urban and small stream flooding.
Flash Flooding Response Updates:
Yesterday, Governor Healey declared a State of Emergency in Worcester and Bristol Counties due to the impacts of Monday night’s flash flooding event. MEMA continues to work with state agency partners, including MassDOT, DCR, MSP, MEP, and others to support communities as they respond to and recover from flooding. Updates from impacted communities are captured in the Regional Updates section.
Impacts/ Potential Impacts
Severe Weather This Afternoon:
Highly saturated conditions continue across much of southern New England, and some locations are still recovering from severe flooding that occurred on Monday. Additional rainfall may worsen existing flooding or trigger new areas of flooding.
Damaging winds are possible, as well as a low risk for a brief tornado.
Hurricane Lee:
The most probable impacts from Lee will be rough surf, rip currents, and beach erosion.
Strong winds and heavy rain are possible, but the magnitude of these depends heavily on Lee’s exact track.
