New York City activated its first Code Blue of the season at 4 p.m. Eastern on Friday, Nov. 13. Mayor Zohran Mamdani said the temperature was expected to fall to 36 degrees, with wind chills reaching freezing. Drop-in centers, warming centers and warming buses are available overnight for people who need a place to warm up.

Find a warm place or request outreach

The mayor’s announcement links to the city’s warming map, which lists locations and hours. You can also call 311 for help finding a site. Check the hours for the specific location you plan to use. If you see someone outside who may need help, call 311 to request outreach. Call 911 for an immediate medical emergency.

During Code Blue, more than 50 city hospitals, as well as Department of Homeless Services drop-in centers and shelters, operate an open-door policy, according to NYC311’s shelter guidance. Outreach teams check on people outside and in subway stations more often. The city’s winter response plan also calls for mobile teams to check on people and connect them with care or a warm place.

The mayor said outreach workers would be canvassing Friday night. To receive the city’s emergency alerts by text, send NOTIFYNYC to 692-692.
