Flash Flooding Possible With 'Unusually Strong' Summer Storm

By Les Masterson

An “unusually strong weather system for August” is expected to hit the area Tuesday night and into Wednesday, according to the National Weather Service.

Heavy rain and minor coastal flooding are expected. Most of the area will see 1-2 inches of rainfall with some isolated areas getting as much as 3 inches.

A flood watch has been issued for the area. The flash flood watch runs from late Tuesday night through Wednesday night. The heaviest rain will happen in eastern Massachusetts during the afternoon and evening on Wednesday, according to the National Weather Service.

Additionally, there may be “embedded thunderstorms” with torrential rainfall with rates up to two inches per hour. If rainfall in that heavy, there will be a potential for urban and localized flash flooding, plus small stream flooding, the weather service said.

The flash flood watch means flash flooding conditions may develop and that flash flood warning may later be issued.

The good news is that parts of Southern New England are “abnormally dry” and need the rain, according to the National Weather Service.
