Long Island, NY - March 20, 2018 - Long Islanders, we’re now officially getting our fourth – yes, fourth – nor'easter of March, and we’re only just past the halfway point of the month! And while the previous storms have been hit-or-miss in terms of the amount of precipitation left in their wake compared to their respective forecasts, the National Weather Service (NWS) is rather adamant in their predictions this time- this nor'easter will likely be a doozy...and on the second day of spring, no less!
 
The NWS has issued winter storm warnings for both Nassau and Suffolk, citing the probability that both Counties could see over a foot of snow in some areas, rendering travel nearly impossible Wednesday during the evening commute.
 
The storm is expected to take the form of rain beginning Tuesday evening that if forecast to transition into snow at approximately midnight; from there, the snowfall will increase in intensity, with the heaviest precipitation set to occur Wednesday afternoon with 1 to 2 inches of snow per hour possible, the NWS says. In addition, strong winds of 20-30 mph with gusts up to 45 mph are expected, which lead to power outages via downed trees, branches, and power lines. Snowfall is expected to last until early Thursday morning, according to reports.

  • A winter storm warning will be in effect all day Wednesday until 8 a.m. Thursday for western Suffolk County. Total snow accumulations of 7 to 10 inches, with localized amounts up to 13 inches, and light ice accumulations are expected.
