Brutal Heat Wave to Roast the South With 115° Feels-Like
US · Published Aug 18, 2026
A formidable heat dome is currently impacting the Southern United States, bringing extreme temperatures and high humidity that are expected to persist through Sunday.
"Feels-like" temperatures are projected to reach up to 115°F in some areas, with approximately 60 million people under heat advisories.

Why It's Important?

The current heat wave is not merely an uncomfortable weather event; it poses a significant public health risk. Extreme heat is recognized as the deadliest type of extreme weather in the United States, claiming more lives annually than hurricanes, tornadoes, and floods combined. The prolonged exposure to high temperatures, especially when coupled with high humidity that prevents effective sweat evaporation, can lead to heat-related illnesses such as heat exhaustion and life-threatening heatstroke. Vulnerable populations, including the elderly, young children, individuals with pre-existing health conditions, and those without access to adequate cooling, are particularly at risk. The lack of overnight cooling exacerbates these dangers, as the body does not have sufficient time to recover from the day's heat. This situation necessitates heightened awareness, proactive heat safety measures, and community support to mitigate the potential for severe health outcomes and fatalities across the affected regions.
