NEW YORK – An earlier issued winter weather advisory for NYC, northeast NJ and northwestern Long Island has been cancelled— forecasters say snow, sleet, freezing rain and ice is expected to slam the tri-state region through the begin of next week, according to the National Weather Service.
Much of NYC and coastal areas will see the icy mix change to plain rain and accumulations will be held to a minimum but the rain may be heavy enough to cause flooding.
Meanwhile, north & west of the city, snowfall will accumulate 3 to 6 inches followed by ice. It should change to all rain late at night or during Sunday.
Even farther inland, up towards I-84 and north, the snow and sleet may reach 6 to 12 inches. The highest snow totals will be seen across Orange and Putnam counties, according to the NWS.
But the National Weather Service says a dramatic drop in temperatures could then turn the watery mess into treacherous ice before Monday, with wind chill temperatures reaching below zero.
The storm will move out of the area during Sunday afternoon or evening and will be quickly followed by a blast of cold air the likes of which we haven't seen in years
The temperature could drop over 30 to 40 degrees in some areas and bottom out close to 0 Sunday night with dangerously low wind chills.
Despite sunshine on Monday, it may not get much higher than 10 to 15 degrees.
Gusty winds, snow and ice may also bring down tree limbs and power lines.
Gov. Andrew Cuomo directed the Department of Transportation and Thruway Authority to ban tractor-trailers and buses on the entire Thruway system, with the exception of the I-95 in Westchester and Bronx counties.
State Emergency Operations Center and about 450 members of the National Guard have been activated to assist the state's storm response.
"As this major winter storm begins to move through the state today and into tomorrow, I urge New Yorkers to take the necessary precautions to keep themselves and their families safe," Governor Cuomo said. "I encourage everyone to remain off the roads unless absolutely necessary to stay safe and to allow our plows to do their jobs safely and efficiently."
NYC Emergency Management has issued a hazardous travel advisory for the city thru Monday—meaning the slush and wet roadways will likely turn to ice , causing extremely dangerous traveling conditions.
"Sunday morning’s high tide could be run well above normal creating issues of coastal flooding. Tidal departures of 1 ½ to 2 ½ feet are forecasted indicating minor to locally moderate flooding."
Temperatures should recover quickly climbing to around 40 by the middle part of the week, but a rain event will accompany the warmup on Wednesday.
Gov. Andrew Cuomo holds a briefing on the latest developments ahead of the storm.
