Zohran Mamdani warned New York City residents to take heatwave weather seriously as a massive heat dome traps more than half of the United States through the July Fourth holiday weekend. He said the conditions are extremely dangerous and urged more than 8 million residents to stay inside and stay cool.
The forecast calls for heat indices of 100 to 115 degrees from the Midwest to the East Coast, with more than 100 record highs and more than 200 record warm overnight lows expected by Saturday. Nikki Nolan said some spots could break records that are more than a century old.
New York City cooling response
New York City is opening cooling centers throughout the five boroughs and, for the first time, deploying vans staffed with nurses and paramedics. The vans will hand out water, electrolytes and sunscreen, perform wellness checks, transport people to cooling centers and make in-home visits to vulnerable residents.
Mamdani said, "These are extremely dangerous conditions" and added, "My recommendation to all New Yorkers is to stay inside and stay cool." He also said, "and if you happen to be getting married at Madison Square Garden, you will be staying inside and you will be staying cool, and I think it's a good example to set for the city at large."
Washington, D.C. and Nashville
The National Weather Service issued an extreme heat watch for Washington, D.C., for Thursday and Friday, where highs of 103 are expected. A high of 101 is forecast for Saturday, July 4, and that would top the capital's highest recorded temperature for that date, 100 degrees, set in 1919.
Muriel Bowser urged residents and visitors to plan ahead, stay in the shade and limit time outdoors. In a social media post, she wrote, "This is your friendly reminder that the sun is not playing around," while the National Park Service told people heading outdoors to stay hydrated, take breaks in the shade, wear a hat and sunscreen, sploot responsibly, know their limits and look out for one another.
In Nashville, temperatures could reach 101 degrees and feel like 114, and heat patrols have begun handing out cold bottled water to the city's homeless population during peak hours. Heat is the leading cause of weather-related deaths, and doctors say warning signs include fatigue, light-headedness, muscle cramps and upset stomach, while heat stroke is marked by altered mental status and confusion.
By Saturday evening, the holiday weekend is set to bring all-day festivities and more fireworks in Washington, D.C., even as heat risks stay high across the Midwest and East Coast. The main question for residents is whether their city lands among the records that fall first, or whether the hotter stretch lasts long enough to push the count even higher.
