Arctic cold NYC weather brings dangerous wind chills

The wind chill in parts of the New York City region reached negative numbers, as an Arctic blast descended on the area Friday.

Temperatures gradually fell during the day on Friday, with the coldest air over the region Friday night.

Wind gusts up to 45 mph behind the frontal passage led to wind chill values well below zero late Friday into Saturday.

Low temperatures were 0 to -5 degrees for south Connecticut and the interior Lower Hudson Valley. Low temperatures were 0 to 10 degrees for northeast New Jersey, the NYC metro area and Long Island.

New York City is expected to issue a Code Blue Weather Emergency. No one who is homeless and seeking shelter in New York City during a Code Blue will be denied. Should you see a homeless individual out in the cold, please call 311 and an outreach team will be dispatched to offer assistance.

Code Blue Weather Emergencies include the following options for the homeless:

  • Shelters: During a Code Blue, shelter is available system-wide to accommodate anyone who is reasonably believed to be homeless and is brought to a shelter by outreach teams. Accommodations are also available for walk-ins.
  • Drop-in centers: All drop-in centers are open 24-hours per day when Code Blue procedures are in effect and will assist as many people as possible for the duration of the emergency. Drop-in staff can also make arrangements for homeless individuals at other citywide facilities.
  • Street homeless outreach: Teams will contact vulnerable individuals on their Code Blue Priority Lists to ensure safety and bring them to shelter. DHS coordinates Code Blue efforts directly with agencies such as DSNY, and the Parks Department, at a borough level.
