Long Island weather: Parts of Suffolk see up to 2 inches of rain but no lasting flooding

Long Island has been spared the dangerous flooding that's been hitting other parts of the region, according to the National Weather Service, and that good luck is expected to continue for the rest of the day.

The East End was getting about 1 to 2 inches around 5:30 a.m., but that rain was expected to move north within the hour and off the Island, Jay Engle, a weather service meteorologist said at the time.

While the risk of flooding has largely passed for Long Island, Engle said, thunderstorms are possible later in the afternoon.

There were rain showers overnight, with the heaviest rain in the central Suffolk areas of Patchogue to Riverhead reporting 1½ inches to 2 inches but no lasting flooding, weather service meteorologist Matthew Wunsch said early Monday.

Island-wide, the weather should be drier by the afternoon, he said.

The worst hit areas of New York included the Hudson Valley, some parts of which got between 5 and 8 inches — flooding streets, necessitating rescues of stranded motorists and killing at least one person.

The weather service had issued a flood watch for all of Long Island Sunday night that extended until 2 p.m. Monday. The flood watch warning is issued by the weather service when conditions are favorable for flooding, but it does not mean flooding will occur, only that it is possible.

The flooding risk, which also applied to New York City and other parts of the region, was due to incoming showers and thunderstorms.

The day’s high temperature is expected to be around 83 degrees, with a low around 67. At night, there’s a 30% chance of showers and thunderstorms, mainly before 8 p.m.
