A total of 18 people have died as a result of a period of extreme cold weather in New York City, its mayor has reported. Since late January, the city has endured a cold snap, experiencing 13 consecutive days of temperatures at 0°C (32°F) or below - one of the longest stretches of sub-zero weather in over 60 years. Zohran Mamdani, an official in the city, stated that tragic losses continue to emerge, with a recent report of another individual succumbing to the harsh conditions. While temperatures are set to rise this week, they will remain below normal levels, prompting pleas for residents to remain vigilant, keep indoors, and assist those in need. The mayor noted that since a Code Blue emergency was announced on January 19, around 1,400 placements were made into shelters, supplemented by additional outreach efforts to help the homeless population. The cold snap has raised significant safety concerns, with severe risks of hypothermia and frostbite, leading authorities to advise caution as melting snow and ice have been forecasted to pose additional dangers.
