SNOW WAY OUT, NY

‘Definitely expect’ accumulation amid nor’easter

Don’t put away those snow boots just yet.

Sunday’s anticipated snowfall in the Big Apple turned out to be a slushy mess of rain — even as the weather delayed flights and knocked out power — but up to 3 inches of powder is forecast for Monday.

A nor’easter moving into town will likely “change a rain-maker into a snow-maker,” AccuWeather meteorologist Dave Samuhel said.

“We definitely expect that to accumulate in the city, and we’ll get about 1 to 3 inches.”

Morning droplets should turn to flakes as an early high dips in the afternoon, forecasts said.

Areas north of the city could see as much as 6 inches to a foot pile up, Samuhel said.

Gov. Cuomo on Sunday put the National Guard on standby and activated the state’s Emergency Operations Center.

He also suspended bus service from the Port Authority terminal to upstate cities, including Buffalo, Rochester, Syracuse and Binghampton until further notice.

Ithaca College, SUNY Cortland and Binghamton University canceled classes for Monday in anticipation of the second wave of the storm.

The city’s fleet of 705 salt spreaders, meanwhile, was loaded and ready for the snow, and 1,500 plows will hit streets if accumulation reaches 2 inches, Sanitation Commissioner Kathryn Garcia said.

Alternate-side parking has been suspended for Monday, with Mayor de Blasio urging residents to rely on public transportation.

“This storm has the potential to cause significant problems as many New Yorkers return from the Thanksgiving holiday,” Cuomo said in a statement.

Indeed, Kennedy, La Guardia and Newark airports were already feeling the pinch Sunday, with nearly 500 flights delayed and more than 60 canceled by the evening, according to the flight-tracking service FlightAware. Nationwide, more than 500 flights had been canceled by Sunday afternoon.

The wintry mix also knocked out power to more than 4,000 Brooklyn customers — most in Dyker Heights and Borough Park — for several hours.

The foul weather moved into the Northeast over the weekend after walloping portions of the Midwest and Plains states.

It was blamed for a number of deaths — including a boy and girl, both 5, whose car was swept away by flood waters in Arizona and a 6-year-old who fell off a snow plow in Utah Friday.

At least nine members of an Idaho family — including two children — were killed returning from a weekend hunting trip when their singleengine plane crashed in a South Dakota cornfield amid the harsh winter storm, officials said.

The city of Lead, SD, was hit with 30 inches of snow, and Duluth, Minn., with up to 20 inches in what locals called a “historic” snowfall.
