Heat dome blankets central U.S. in dangerous, prolonged heat
A heat dome is trapping heat across the central United States, pushing temperatures above 100 F from the Southwest to the Midwest and leaving roughly 70 million people under heat advisories. Overnight lows will stay high, humidity will be oppressive, and vulnerable populations are at risk as the heat persists through the week with limited relief anticipated. Officials urge cooling measures, hydration, and access to air conditioning or cooling centers as authorities monitor the situation.
