Millions at Risk as Scorching Heat Wave Grips Eastern US

A dangerous heat wave is sweeping across the eastern United States, impacting nearly 160 million people and bringing record-breaking temperatures to major cities like New York, Washington, and Boston.

Temperatures in the New York area are expected to reach up to 102°F (39°C), with extreme heat warnings in effect across 29 states.

Authorities have urged people, especially vulnerable groups, to stay hydrated and use cooling centers.

Experts describe this as a heat dome— a high-pressure system that traps hot air— creating rare, long-lasting heat with little nighttime relief.

Scientists link these intensifying heat waves to climate change, warning that extreme heat remains the deadliest weather-related hazard in the US.
