The city is under a deep freeze, making it difficult and dangerous to stay outside for any length of time.
The high temperature on Friday was a frigid 18 degrees, but Saturday’s high is expected to be a bit warmer and may hit 27 degrees.
Plummeting temperatures can be life threatening for infants, the elderly and the homeless, and Mayor Bill de Blasio urged vulnerable residents to avoid driving and stay indoors.
"It is deceptively cold. It is the coldest it's been all year. And people sometimes think it doesn't feel so bad but if you stay out there too long it will feel bad and will be dangerous particularly to folks who are vulnerable," De Blasio added.
By law, residential buildings in the city must be kept at temperatures of at least 68 degrees during the day and 55 degrees at night.
De Blasio is reminding tenants who believe their building is not being properly heated to call 311.
The freezing temperatures are grinding subway repairs to a halt, as the Metropolitan Transportation Authority says that they're canceling all previously scheduled work on the Subways with the exception of the 6, N and R lines, where more long-term work is taking place.

NY1 spoke with some Staten Island residents who had their own tips for keeping warm.
"Layer up. Hat, gloves, layers of clothes. Don't stay out too long, that’s all. Do what you gotta do, go back inside,” said one New Dorp resident.
"We basically stay in the house and play games, snuggle, get under blankets,” said another.
"We've been lucky for the last three years. We're due for a bad winter, that's my opinion,” said a third.
While the streets are still covered with snow, alternate side parking regulations are suspended Saturday, and as the Sanitation Department focuses on clearing snow, trash pickup with not resume until all snow removal is done.
Today may be a good time to actually enjoy all that snow, as the Parks Department declared its first ever Snow Day throughout the city.
At parks in each borough, the department will host free activities such as sledding and snowman and snow angel competitions.
There will also be music and free hot chocolate.
From 11 a.m. to 3 p.m., the events will take place at Crotona Park in the Bronx, Prospect Park in Brooklyn, Highbridge Park in Manhattan, Juniper Valley Park in Queens and Clove Lakes Park in Staten Island.
