Heat Dome Brings Dangerous Heat to 80 Million Americans

A largely stationary heat dome is driving dangerous, humid heat across the central and southern United States, with heat advisories affecting roughly 70 million to 80 million people. Forecast highs of 95 to 105 F, with higher temperatures in parts of the Southwest and western Nebraska, are expected to persist into the following week with limited overnight cooling. Authorities are urging residents, especially older adults, children, people with medical conditions, and outdoor workers, to use air-conditioned spaces, hydrate, and limit sun exposure.
