Long Island is under a flash flood watch as thunderstorms are forecast to bring heavy rains to the area, possibly bringing as much as two inches per hour through Tuesday evening.
Showers are likely to intensify after noon with possible accumulations of up to four inches of rain in some areas, according to Upton-based National Weather Service meteorologists.
“Flash flooding is a very dangerous situation,” NWS warned in a statement.
A flash flood watch means that conditions may lead to flash flooding. NWS may issue a flash flood warning if that likelihood increases.
Scattered thunderstorms are expected to continue through Wednesday morning before the skies clear up giving way to mostly sunny forecasts in the 80s through the weekend.
