Looks like Long Islanders need to switch into rainfall mode -- meaning umbrellas, slick roadways and potential flooding.
The week brings the possibility of several periods of heavy rain, starting Tuesday night into Wednesday, the National Weather Service said.
From 1 3/4 to 2 inches of rain, locally higher with any thunderstorms, are forecast from 8 a.m. Tuesday to 8 a.m. Thursday, said Joe Pollina, weather service meteorologist based in Upton.
Tuesday brings expected high temperatures in the upper 70s to around 80, he said, and a 40 percent chance of showers, jumping to 70 percent Tuesday night and Wednesday, which is looking at highs in the mid-70s.
Indeed, the weather service issued a hazardous weather outlook telling of possible flash flooding, but more likely minor flooding of urban and poor drainage areas from Tuesday night into the weekend.
The rain is "much needed," said Rich Hoffman, News 12 Long Island meteorologist. Since May, most of Long Island has been in moderate drought, the least intense category of the U.S. Drought Monitor.
Adding to the potential for rain is a tropical depression expected to become a tropical storm on Tuesday that was 425 miles southwest of Bermuda as of Monday afternoon. The system, moving west, was expected to turn to the west-northwest in the coming day or two, according to the National Hurricane Center, which also said there's much uncertainty as to the system's track forecast.
Wednesday brings highs in the mid-70s. But expect daily highs in the mid-60s, starting by Thursday, Hoffman said.
"As we turn the calendar into October, colder weather will settle over Long Island," he said.
