New York City is being hit with a dangerous heat wave this week, as heavy humidity and blazing summer temperatures are expected to make it feel close to 110 degrees in parts of the city.

The National Weather Service issued an Extreme Heat Warning for New York City, including Brooklyn, as the worst of the heat is expected Thursday and Friday, with hot and humid weather continuing into the weekend. Forecasters warned that warm nights will bring little relief, while scattered thunderstorms may develop during the afternoons or evenings.

The heat is part of a wider summer pattern affecting large areas of the United States, with much of the country seeing intense heat, heavy humidity, and sudden storms. Longer-range forecasts have also pointed to a hotter-than-usual summer for the Northeast, with more frequent stretches of oppressive heat.

City officials said they are preparing for an unusually severe weather event. “I am asking every New Yorker to make a heat plan before the worst of this weather arrives,” Mayor Zohran Kwame Mamdani said. “The best protection against extreme heat is air conditioning.”

NYC Emergency Management Commissioner Christina Farrell said the city is also relying on residents to look out for one another. “The neighbor who knocks on the door, the family member who calls to check in, the stranger who stops to help,” she said, calling that the city’s most powerful tool during the heat emergency.

Governor Kathy Hochul urged New Yorkers to prepare for multiple days of extreme heat, warning that some areas could see “feels-like” temperatures up to 110 degrees. Officials said the danger grows when high heat continues for several days in a row, especially for older adults, young children, and those with medical conditions.

Residents are urged to drink water, stay cool, and avoid spending unnecessary time in the strongest heat of the day. A cool indoor place can make a major difference during the hottest hours of the day.

Parents and drivers are reminded that a child must never be left in a parked car, even for a minute. Cars heat up rapidly in summer weather, even with the windows cracked, and the situation can become life-threatening very quickly.

Families are also urged to check clearly and directly on elderly parents, grandparents, neighbors, and anyone living alone, especially if they may not be using air conditioning. A quick call or visit during extreme heat can prevent a serious emergency.
