It’s going to be another wet day on Long Island.
The National Weather Service’s Upton office said Thursday’s forecast calls for heavy rain and possible flooding, with some of the storms producing gusty winds and potential thunderstorms.
A flood watch is in effect for the entire Island through the afternoon and a coastal flood advisory for the south shore will last until 9 p.m., the weather service said.
In a statement, the weather service said rainfall could be heavy at times before gradually decreasing Thursday night.
“Thunderstorms with locally heavier rainfall rates of at least 1 inch per hour are possible, especially during this afternoon,” the agency said.
Rainfall amounts of 1 to 2 inches are possible, forecasters said.
Flooding of vulnerable shore roads is possible, said the weather service, which also warned of minor coastal flooding around the times of high tide.
While the heaviest rain is expected to stop falling in the afternoon, showers and thunderstorms will be possible through the evening.
Friday’s forecast calls for mostly cloudy skies with a chance of showers in the afternoon.
The good news is the weekend is expected to feature sunny skies and temperatures in the 50s.
