A Code Blue goes into effect Saturday at 4 p.m. across New York City as temperatures drop to frigid conditions.

A Code Blue is issued when the temperature drops to 32 degrees Fahrenheit or less across the city. It also means that anyone who is seeking shelter citywide will not be denied if they head to a Code Blue center like a library or shelter.

The Arctic-like temperatures also impacts renters. When it's this cold out, the temperature in the apartment should not fall below 68 degrees during the day between 6 a.m. and 10 p.m., and should not fall below 62 at night. If it does, renters should report it to 311.

Residents walking on the streets should be aware of ice patches for they are easy to slip or skid on.

Gov. Kathy Hochul provided safety tips on how New Yorkers can prevent hypothermia and frostbite. She says to avoid going outside but if you must, be sure to keep hands and feet covered.

If you start experiencing drowsiness or slurred speech after braving the low temperatures, seek medical attention immediately as these are signs of hypothermia.

The governor also warned against an increased risk of fire and carbon monoxide poisoning from alternative heating sources, like portable space heaters.

It is important to turn space heaters off when you’re not at home with them. Try to keep them away from furniture and hanging window treatments as this can lead to a fire.
