Flash Flood Watch in Effect as Downpours Soak LI

Predictions of heavy downpours Tuesday have forecasters warning residents of possible flash flooding across Long Island, according to the National Weather Service.

A flash flood watch is in effect through the afternoon, the Upton-based NWS said, adding that up to 2 inches of rain is likely to fall on LI as a system moves toward the region.

And it may be a quick-hitting rain storm.

Meteorologists said rainfall could occur over a short period of time at a rate of 1 to 2 inches per hour.

The storm could produce flash flooding of small streams and in urban, low-lying and poor drainage areas, the NWS said.

The system could also produce thunderstorms after 5 p.m. Tuesday, forecasters said.

The forecast for the remainder of the week calls for sunny skies through Saturday.
