BOSTON — We’re on a SEVERE WEATHER ALERT from the Boston 25 Weather Team due to a flash flood warning and flood watch for parts of southern New England, including Massachusetts.
In Massachusetts, the flash flood warning is in effect for southwestern Bristol County and south central Plymouth County until 2 p.m.
“Flash flooding of small creeks and streams, urban areas, highways, streets and underpasses, as well as other poor drainage and low-lying areas,” the National Weather Service warned.
The NWS added, “Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles.”
In Massachusetts, the flood watch is in effect for Bristol, Plymouth, Barnstable, Dukes, Nantucket, Worcester, Norfolk, and Suffolk counties through 6 p.m. Sunday.

“This cluster of heavy rain will slide into Southeast Massachusetts through the late morning hours. Flood watches remain in effect until 6 p.m. along and south of the Mass Pike,” Boston 25 meteorologist A.J. Mastrangelo said.
Showers and a few embedded thunderstorms with localized, narrow bands of torrential rainfall are possible.
Widespread rainfall amounts of 0.50 to 2 inches are expected. However, localized narrow bands of 2-4″ of rain are possible within a 3-hour period.
“While it remains uncertain whether these narrow bands of heavier rain will occur, localized flash flooding is possible, especially if it occurs over a vulnerable urban center,” the NWS warned.
