Scattered thunderstorms could dampen outdoor plans, meteorologists said Friday as they forecast less heat but a muggy weekend and a high possibility of flash flooding with bursts of rain into Monday evening.
“It’s really the whole Island that’s fair game for this,” said David Stark, a meteorologist with the National Weather Service in Upton, speaking of the flash-flood warning in effect from late Friday through Sunday morning. “There’s not one spot that is more susceptible than any other.”
Stark said Nassau’s southern coast will also be subject to coastal flooding during high tide, making those South Shore spots vulnerable to a double dose of water. The weather service reported Friday that Nassau and some spots in western Suffolk could see torrential rains of 1 to 2 inches an hour.
“That could occur if the timing of the rain coincides with high tide,” he said. “That could make the situation a little worse, but I wouldn’t say that’s a guarantee.”
He did promise, though, that the weekend will be humid and will feel like summer, even though the temperatures on Saturday and Sunday may not break the 80-degree mark.
“On Sunday there’s a little less chance of rain compared to Saturday, but there’s still a pretty good chance,” he said. “The humidity is going to be there both days and on Monday we’re back in the lower 80s.”
But Monday carries a good chance of scattered showers, too.
“It’s going to feel like summer right into the week,” Stark said.
