Potentially severe thunderstorms producing damaging wind gusts and hail will pass through the greater Boston area around 3 p.m. on Tuesday, the National Weather Service (NWS) warned earlier this afternoon.
The NWS issued a severe thunderstorm watch shortly before 2 p.m. for eastern Massachusetts, citing a line of strong thunderstorms moving southeast at 35 miles per hour and extending from the Massachusetts-Vermont border to Manchester and Portsmouth, New Hampshire.
The NWS said the thunderstorm line will reach the Route 2 corridor in northern Mass by 2:30 p.m. and Worcester and Boston around 3 p.m.
Along with strong wind gusts and the potential for large hail, the thunderstorms could bring frequent lightning and torrential rainfall.
"For your safety, get inside when these storms approach," the NWS statement said. "Heavy rain may cause minor street flooding and ponding of water in low lying areas such as underpasses. Do not drive through flooded roads."
The severe thunderstorm watch remains in effect until 8 p.m. for most of Massachusetts and southwest New Hampshire.
