The massive storm hitting the New York City area has officially been classified as a blizzard, according to the National Weather Service in New York.

Meteorologists reported that at least six weather stations in the region reached blizzard conditions early Monday morning, including:

Islip and Westhampton in Suffolk County

Newark and Teterboro in New Jersey

New Haven, Groton, and Bridgeport in Connecticut

Other areas in the region experienced “blizzard-like conditions,” officials said.

Nearly two feet of snow has already fallen on parts of Long Island as of mid-morning Monday. The storm, a powerful nor’easter, has brought heavy, steady snow, strong winds, and hazardous blizzard conditions. Forecasters said the storm is “past peak but still significant” as of late morning.

What is a blizzard?

The National Weather Service defines a blizzard as a storm with:

Sustained winds or frequent gusts of 35 mph or more

Falling or blowing snow reducing visibility to a quarter-mile or less for at least three consecutive hours

The first qualifying measurement at a weather station was recorded around 1 a.m. Monday.

How strong have wind gusts been?

The strongest gust recorded during the blizzard in New York was 84 mph at 3:30 a.m. at Montauk Point in Suffolk County. The second strongest gust reached 74 mph at Stony Brook (Suffolk County) at 5:19 a.m.

Both of these gusts are considered hurricane-strength, equivalent to a Category 1 hurricane on the Saffir-Simpson scale, which ranges from 74 to 95 mph, according to the Weather Service.
