A storm system that has drenched parts of the nation is forecast to bring heavy rains to Long Island, causing flooding that will likely make for a messy Friday evening rush-hour commute.
The slow-moving storm, which is expected to bring up to three inches of rain to the area, prompted the National Weather Service to issue a flash flood watch for Nassau County and much of the New York Metro area from noon Friday to 6 a.m. Saturday.
“Rain will increase in coverage during the afternoon and become heavy at times at night,” the agency’s Upton-based meteorologists said in a statement. “The heaviest rain is expected to coincide with high tide on the Atlantic and western Long Island Sound tonight, which could exacerbate flooding along the south shore of Long Island.”
A flash flood watch means that the heavy rainfall may cause streams and rivers to overflow, causing potentially dangerous conditions.
Once the storm tapers off, temperatures near 70 Friday are forecast to stay the same through the weekend into next week, with temps dropping into the 40s after sundown.
Mostly cloudy skies Saturday are expected to become sunny later in the day through Sunday and in the run up to Memorial Day weekend.
