On August 13, 2025, the National Weather Service (NWS) has issued heat-related alerts for at least 16 states across the United States, as the country grapples with a scorching heatwave. The agency has cautioned residents in many affected areas to stay out of the sun and has forecast "dangerously hot conditions" in parts of the country.
Extreme heat warnings, which the NWS issues when "extremely dangerous heat conditions are expected or occurring," have been put in place for southern Nevada, southeast California, parts of Arizona, including Phoenix and the Grand Canyon, and a portion of southern Utah. In Death Valley, often dubbed the hottest place on Earth, temperatures between 118 and 122 degrees Fahrenheit are possible, while Lake Havasu City in Arizona could see temperatures between 112 and 116 degrees.
The Centers for Disease Control and Prevention (CDC) has warned that extreme heat can trigger heat-related illnesses, particularly among vulnerable populations such as older adults, young children, and those with certain medical conditions. The agency notes that extreme heat contributes to more than 700 deaths annually across the U.S. Additionally, rising temperatures can worsen ground-level ozone pollution, potentially compounding existing health risks.
