After bouts of pummeling rain, the bulk of precipitation had pretty much cleared Long Island Monday afternoon, and was making its way off the Twin Forks, forecasters said.
Rain was “moving out pretty quickly,” said Faye Morrone, National Weather Service meteorologist in Upton.
Still, look for some possible showers, with chances decreasing through the afternoon, and a slight chance of a thunderstorm, forecasters said.
Localized minor coastal flooding is expected with Monday night’s high tide at “vulnerable locales along the Great South Bay and Jamaica Bay,” the weather service said.
With on and off heavy rain, the Island, as of late morning, had seen 1 to 2 inches, with highest amounts “more prevalent along the northern Nassau/Queens border,” said Jay Engle, National Weather Service meteorologist in Upton.
The heavy rain opened up a sinkhole in Westbury, making for a “potentially very dangerous situation,” Mayor Peter Cavallaro said in an alert to residents.
The mayor urged residents to avoid the area of the sinkhole, at Pepperidge Road and Baldwin Drive.
Flood advisories that had been in effect for Nassau and Suffolk until 2 p.m. had expired, forecasters said.
In the air, Kennedy and LaGuardia airports reported cancellations and delays due to the weather.
Morning temperatures had been in the low 40s across the Island Monday, with Long Island MacArthur Airport recording 56 degrees shortly before 2 p.m., with wind gusts of 31 mph.
