Rain today, possibly heavy at times, may cause flooding of rivers, creeks, streams, and other low-lying and flood-prone locations today, the National Weather Service said.

A flood watch is in effect through late tonight for Suffolk County.

Showers and thunderstorms will produce heavy rainfall which could result in rainfall rates up to one to two inches per hour at times. Areas receiving multiple rounds of showers and thunderstorms with heavy rain have a chance for flash flooding in low lying, poor drainage and urban areas.

A cold front and wave of low pressure along it will approach today, moving through tonight, weather forecasters in Upton said. High pressure then builds in on Thursday, remaining centered to the west through Friday. At the same time, Hurricane Lee is forecast to pass offshore to our east Friday evening.
