It’s shaping up to be a week of turbulent weather in the New York metro area.
After Monday’s downpours inundated roads and disrupted travel, meteorologists warned of a coming heat wave over the next few days. They said high temperatures and humidity levels would drive the heat index into the low- to mid-90s Tuesday and into the triple digits Wednesday and Thursday.
The heat index, or real-feel temperature, could be “5 to 10 degrees higher than the actual temperature” this week, National Weather Service meteorologist Bryan Ramsey said. Real-feel temperatures will likely peak Thursday at 100 to 104 degrees, he added.
There are also chances for showers and storms through Friday, according to the weather service.
New York City officials said cooling centers would be open Tuesday in every borough. You can find your nearest cooling center here or by calling 311.
Mayor Eric Adams and emergency management officials urged New Yorkers to take precautions and check on their neighbors amid the extreme heat.
“Drink water, avoid outdoor activity during the hottest hours and don’t wait to seek help if you’re feeling lightheaded or ill,” he said in a statement. “We’re also asking everyone to do their part to conserve energy. Set your air conditioner to the highest comfortable temperature and limit use of large appliances during peak hours.”
Officials have activated the city’s heat emergency plan, so agencies will coordinate to respond to heat-related risks and outreach workers will encourage homeless people on the streets to go to shelter and cooler settings.
More than 500 people die from heat-related illness in the city annually, officials said. Those without air conditioning are at the greatest risk.
