One more frigid night | Live updates

As Sanitation Workers continue to work 12-hour shifts clearing massive amounts of snow and ice from the Jan. 25 snowfall, the New York City Department of Sanitation (DSNY) has issued a Winter Operations Advisory for Friday, February 6, beginning at 6 p.m.

A Winter Operations Advisory is the Department's "lower level" snow-fighting notification, as opposed to the "higher level" Snow Alert.

More than 700 salt spreaders and specialized bike lane spreaders are filled and ready to go at the first sign of precipitation, and the Department has hundreds of millions of pounds of salt on hand.

DSNY has also been hauling snow from every corner of the city and bringing it to 13 melters in all 5 boroughs. To date, the Department has melted more than 230 million pounds of snow, and will continue to do so for days, if not weeks, to come.

NYC Ferry will remain suspended through the weekend.

Officials expect to begin a gradual return to service next week, likely starting with limited or modified routes.

"Crews are testing docks and routes to see what is possible. Combined with ongoing forecasting and landing by landing ice tracking, these tests allow us to better predict conditions and prepare operations for a safe and reliable return. While slightly warmer weather has helped break up some ice, large ice floes are still moving through the harbor. With cold temperatures and strong winds expected this weekend, conditions will remain challenging. Safety comes first, and our teams continue to closely monitor conditions. Looking ahead, forecasts, show temperatures rising above freezing by the middle of next week. As conditions continue to improve, and as we continue our testing, we expect to begin a gradual return to service next week, likely starting with limited or modified routes."

Mayor Zohran Mamdani reported that a 17th person has died as a result of exposure to the cold weather in New York City.

The mayor said that as long as cold temperatures remain, so does the risk to life and that New Yorkers should take precautions.

Three of the deaths were said to be drug-related but others were due to hypothermia with one death was from an unknown cause.

Mayor Mamdani warned that Saturday's temperatures could feel like 10 below zero.

So far, the city has had 1,100 placements into shelters and safe havens since Monday, January 19.

Twenty people have been involuntarily transported.

The mayor also mentioned that a low-barrier Safe Haven with 106 beds opened Wednesday in Lower Manhattan.
