US · Published Aug 20, 2026
A persistent heat dome is causing a dangerous heat wave across the southern U.S., with temperatures soaring into the triple digits.
Heat indices have exceeded 105°F (40.5°C) in areas like southern Georgia, coastal South Carolina, and the Florida Panhandle.

Impact & Risks

The extreme heat poses significant health risks, particularly for vulnerable populations such as the elderly, children, and those without access to air conditioning. Prolonged exposure to high temperatures and humidity can lead to heat exhaustion or heat stroke. Urban areas are especially at risk due to the heat island effect, which can exacerbate nighttime temperatures.
