A bitter blast of extreme cold continues to take hold over New York, with city officials urging residents to stay indoors if possible.

An Extreme Cold Warning is in effect across the Tri-State area until 1 p.m. on Sunday amid bright but still dangerously cold conditions.

Atkins works outside to keep the streets clean.

"With this job, I'm constantly outside for 10 hours. I go inside once in a while and get some heat, then I come back out with my broom and my dustpan and my barrel and we go around the block again and again and again,"

More than 60 warming centers are open across New York City this weekend - even vehicles are being used to help people who have nowhere to go,

The wind is likely to blame for startling damage at a gas station in New Jersey.

When the temperature is 32 degrees or lower, including wind chill values, the City follows Code Blue procedures.

An Enhanced Code Blue is activated when at least one of the the following criteria is met:
- Continuous or accumulating precipitation (snowfall of 3 inches or more)
- Ice storms and/or freezing rain
- Temperature or wind chills below -5 F (any amount of time)
- Sustained winds of 40 mph (or higher)
- At the request of New York City Emergency Management (NYCEM) or City Hall

Outreach teams are intensifying their efforts to reach and support the most vulnerable New Yorkers amid dangerously cold weather.

"No one who is experiencing homelessness and seeking shelter in New York City will be denied. Should you see an individual experiencing homelessness out in the cold, please call 311 and city staff will be dispatched to offer assistance," NYC DSS said.

During a Code Blue event, homeless people may also stay at any Department of Homeless Services shelter or drop-in center without going through the normal intake process.
