A Flood Watch remains in effect for much of the South Shore until 4 p.m. Thursday, as heavy rains continue to cause water to pool on roads and in low-lying areas. Cohasset Police closed Route 3A at Lower King Street earlier this morning due to flooding, as runoff overwhelmed the area during a particularly intense period of rainfall.
The National Weather Service issued the Flood Watch for eastern Massachusetts and parts of Rhode Island, warning that excessive rainfall could lead to flooding of creeks, streams, and urban areas with poor drainage. The watch includes all of Plymouth County, as well as Norfolk, Suffolk, and Bristol counties.
“Flooding caused by excessive rainfall continues to be possible,” the National Weather Service said in its advisory. “Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations.”
Local departments have not reported any injuries or rescues as of Thursday morning, but transportation officials and police departments across the South Shore have advised residents to avoid driving through standing water and to monitor conditions throughout the day.
In Cohasset, police advised drivers to seek alternate routes while Route 3A southbound remained closed between Lower King Street and the Beechwood neighborhood. Water was reported to be several inches deep across the roadway. There is no timeline yet for when the road will reopen.
Additional localized flooding was reported in Hingham, Weymouth, and parts of Quincy, though no major road closures were confirmed in those communities as of 10 a.m.
The heaviest rainfall is expected to taper off this afternoon, though forecasters warn that the risk of localized flooding may continue through early evening, particularly in low-lying areas and places with poor drainage.
Residents are urged to monitor forecasts and prepare to take action should conditions worsen.
