Heat Dome Threatens Two-Thirds of U.S. | Honolulu News

A blistering heat dome is sweeping across the U.S., with triple-digit temps gripping the Southwest and Great Plains—and it’s here to stay for at least a week, possibly affecting two-thirds of the country. Nighttime lows won’t cool off either, leaving bodies unable to recover, and over 90 local temperature records could be tied or broken by Wednesday—including dangerous overnight highs. Driven by climate change and amplified by a record-strength El Nino, this extreme heat is pushing cities like Las Vegas to over 110°F and Miami/Tampa to stay above 80°F at night. Experts warn of heightened wildfire risks and urge everyone to stay hydrated, seek shade, and take extreme precautions—this could be one of the most powerful heat events to hit the Dakotas in 25 years.
