On this rainy, windy Thursday, look for some heavier precipitation during the later afternoon hours.

An area of moderate to heavy rain was moving into New York City around 3:30 p.m., heading for Long Island, said Joe Pollina, National Weather Service meteorologist in Upton. Locally heavy rain could come with any embedded thunderstorms, he said.

A flood watch is in effect for Long Island until 8 p.m. Thursday, telling of the potential for flooding of rivers, streams and poor drainage areas, the weather service said.

A coastal flood advisory is in place from 4 to 9 p.m. Thursday for western Long Island’s ocean beach front and bays. That means flooding for the most vulnerable shore roads and basements, the weather service said. Only isolated road closures are expected.

In all, an inch and a half to two inches of rain is expected, with the bulk to fall in Nassau and western Suffolk, the weather service said in a tweet. Rainfall amounts could be higher in areas that see any thunderstorms.

As of 3:30 p.m., Upton had seen 0.65 inch of rain, Long Island MacArthur Airport got 0.29 inch and Shirley saw 0.42 inch, Pollina said.

Shortly before 3 p.m., light rain with fog and mist was reported at the airport, with winds from the east at 16 mph. The temperature was 50 degrees.

The windy weather was causing delays at LaGuardia and Kennedy airports Thursday, the Federal Aviation Administration said on its website. Travelers were urged to check with their carriers about possible flight delays.

A chance of showers remains for Thursday night and into Friday.

Hang on, though. “Nice, drier and warming trend, starting Saturday, through next week,” said Rich Hoffman, News 12 Long Island meteorologist.
