Officials are urging residents to be careful on the roads and sidewalks that are icy following the biggest snowstorm of the season.
With the single digit temperatures, there are warming centers open to the public at three locations in The Bronx.
There is also a Code Blue in effect until 8 a.m. Tuesday morning.
If you see any vulnerable New Yorkers out on the street, call 311 and they will pick them up and bring them to a nearby shelter to keep warm.
