Over 2,600 Without Power On Long Island; 60 MPH Winds Possible

More than 2,600 PSEG Long Island customers were without power Thursday night and that number may rise considerably as wind gusts up to 60 mph slam the region.

A high wind advisory is in effect from 8 p.m. until 6 a.m. for Nassau County and western Suffolk County. A high wind warning is in effect for the same period for the East End. Wind gusts up to 50 mph are possible in the advisory area and up to 60 mph in the warning area, the National Weather Service says.

Strong winds will blow down scattered limbs, trees and power lines. Scattered power outages are expected. As of 7:17 p.m., PSEG says 2,662 of its customers were without power. See the PSEG outage map.

The rain spared trick-or-treaters Thursday, but a few strong thunderstorms are possible as a cold front pushes through the area overnight with damaging wind gusts and heavy rain being the primary threats. The strongest winds and the potential for thunderstorms will come after midnight. The rain should end by sunrise Friday.

"Be alert!," PSEG wrote on its Facebook page Thursday evening. "The strongest winds are yet to come. Tonight's forecast calls for high wind gusts and possible thunderstorms.To report and get updates about a power outage, text OUT to PSEGLI (773454)."

Breaking waves of 9-13 feet along the Atlantic Ocean beachfront will result in widespread beach erosion and flooding during the times of high tide overnight.

Scattered areas of dune erosion are possible, with localized washovers where dune structures have been compromised by earlier storms, the weather service says. Wave splashover may cause minor flooding to a few shoreline roads and properties on the South Shore.
