With winds gusting to over 40 mph on Long Island Wednesday afternoon, a wind advisory remains in effect through 8 p.m., telling of winds from the northwest of 20 to 30 mph, gusting as high as 45.

The highest winds were expected for the afternoon and early evening, the National Weather Service said.

These are the kinds of winds that “will blow around unsecured objects” and could take down tree limbs, meaning the chance for a few power outages, the weather service said.

Arrival delays at LaGuardia Airport late Wednesday afternoon were averaging around two hours as a result of the winds, according to the Federal Aviation Administration’s web site. Departures could also be affected.

That’s as a cold front has brought temperatures down more than 20 degrees from Tuesday’s high of 58 at Long Island MacArthur Airport.

As of just before 3 p.m. the temperature at Long Island MacArthur Airport was 35 degrees, feeling more like 22 with the wind chill, with gusts from the northwest of 38 mph, and those of 41 mph recorded earlier in the afternoon.

“Cold,” said Rich Hoffman, News 12 Long Island meteorologist, with “temperatures well below normal this afternoon, near record low tonight.”

Given the windy conditions and low relative humidity, there’s an enhanced risk Wednesday for brush fires to spread, should any start, the weather service said.

As for the overnight hours, lows are going down to around 18 degrees, feeling colder, as gusty winds continue.

Thursday brings mostly sunny skies, with continuing breezy and cold conditions, and highs in the upper 30s.
