Nor’easter Dumps 20 Inches of Snow on Long Island

More than a foot of snow fell in four hours in Islip, NWS said.

The fourth nor’easter forecast to hit Long Island in a month dropped 20 inches of snow—with a foot falling in four hours in Islip Wednesday night into Thursday morning, meteorologists said.

The National Weather Service lifted the winter storm warning and coastal flood advisories for Nassau and Suffolk counties, although a special weather statement was still in effect for eastern LI as the last bands of snow went out to sea. The highest snowfall amount recorded on the Island—and the tri-state area—as of Thursday morning was 20 inches in Patchogue. Hundreds of schools and businesses were closed, and thousands of flights were canceled as the cleanup got underway and PSEG Long Island worked to restore power to more than 5,000 customers.

“With breezy conditions following the departing system and below-normal temperatures in the lower 40s, it will feel as if temperatures are in the low to mid 30s for most of the day,” Upton-based NWS forecasters said in a statement. “Below-normal temperatures continue into the weekend as Arctic high pressure builds to the north.”

The latest storm, which arrived after Tuesday’s vernal equinox, follows nor’easters on March 2, 6 and 12 left snow, flooding and power outages in their wake.
