Light rain that has hampered the Saturday morning commute is expected to turn heavy as the weekend progresses, according to forecasters, with both a wind advisory and coastal flood watch in effect.
Forecasters are calling for heavy rain throughout the afternoon Saturday with 40 mph winds. Gusts may exceed 50 mph as the day progresses.
The rain is predicted to continue overnight and into Sunday, with wind speeds of 25 to 35 mph tonight, then diminishing to 10 to 15 mph tomorrow.
Because of the expected heavy winds, the National Weather Service has released a wind advisory in effect until midnight Saturday. In addition to the sustained winds of 25 to 35 mph across Long Island, New York City could see 35 to 40 mph winds, with gusts of up to 60 mph at higher elevations.
The combination of heavy rain, gusty winds and an already precipitation-soaked area has led to a coastal flood watch by the National Weather Service, in effect until 4 p.m.
According to the weather advisory, minor to moderate coastal flooding is possible near the time of high tide this evening. Moderate beach erosion is also a possibility according to the advisory, with the windy, wet weather bringing waves of 8 to 12 feet.
