Southern U.S. under extreme weather advisory as "heat dome," humidity build

Millions in southern U.S. states, including Texas and the Carolinas, are facing a brutal heat wave, with temperatures soaring under what meteorologists call a "heat dome." This intense heat combined with high humidity levels is making it feel even worse, and officials have issued extreme weather advisories. This situation is significant because prolonged exposure to such extreme heat can lead to serious health risks, including heatstroke and other heat-related illnesses, especially for vulnerable populations. The severity of the weather underscores the urgent need for public awareness and safety measures to mitigate these risks.
