NY winter storm total snowfall forecasts range from flakes to feet in parts of the state: National Weather Service

STATEN ISLAND, NY — The National Weather Service has expanded the number of counties in New York forecast Wednesday to be at risk of severe winter weather.

The agency expanded the area under winter weather warnings as the storm approached, with gusty winds and snow expected to be intermittently strong in some parts of the state.

Forecasters expect up to a foot of snow to affect northern parts of New York, while a broad swath of west and central New York could show an accumulation of about 15 cm.

Almost all of New York is under a winter weather advisory or warning.

Beginning in the far north of the state, along areas like the St. Lawrence Valley on the border with Canada, the National Weather Service said between 6 and 12 inches of snow were possible. Additional ice accumulation is also expected.

Western parts of the state, including Buffalo, Syracuse and Ithaca, are in effect with a winter weather advisory beginning around 10 a.m. and lasting through Wednesday evening. The National Weather Service said morning through early afternoon snow is turning into a wintry mix that could affect travel.

Wind gusts of 40 miles per hour and snowfall rates that may exceed half an inch per hour are forecast for the eastern parts of the state this afternoon. Albany was able to achieve an accumulation of about five inches.

Further inland, areas like Rockland County are expected to have milder snow depths — just a few inches — but conditions could still be encountered, causing evening commutes to be treacherous, according to the National Weather Service.

AccuWeather expects snow to be felt in the lower half of the state early Wednesday afternoon, pushing the storm’s start time later than previous expectations.

Some northern parts of the state will experience snow arrival times a little later in the afternoon to early evening, ahead of areas farther north along the east coast.

Gusty cold air following behind the storm is expected to keep additional snow showers lingering through Thursday, though no significant additional accumulation is expected, according to AccuWeather.

“The potential of this storm to negatively impact travel is significant and, from an aircraft perspective alone, is probably the most disruptive in a month prior during the Christmas season arctic cold and snow spell,” said Alex Sosnowski, AccuWeather’s lead weather forecaster, in a briefing .

The slightly later start time of the storm will significantly reduce the chance of clustering in New York City, an AccuWeather forecaster told Advance/SILive.com.

“We can’t rule out some snowflakes interfering in New York City, Manhattan, Bronx, Queens, Brooklyn and maybe Staten Island, but for now it looks like the chances are dwindling just because of the later start time now. said Tyler Roys, a senior meteorologist at AccuWeather.

However, other impacts are expected to affect Staten Island.

Strong winds, which will be particularly pronounced later Wednesday night, could reach 45 miles per hour, worsening coastal flooding along Staten Island’s east coast and affecting travel on the borough’s bridges. Some localized flooding is expected in vulnerable areas combined with heavy rain.

A coastal flood warning is in effect for the district from 9 p.m. Wednesday to 3 a.m. Thursday, the National Weather Service said.
