South Heat Wave to Bring Triple-Digit Highs and Record Temperatures
US · Published Aug 17, 2026
A dangerous heat wave is gripping the southern United States, with temperatures soaring into the triple digits across states from Texas to Florida and the Carolinas.
The heat wave, intensified by high humidity, is pushing heat indices above 105°F (40.5°C) in many areas, with some locations experiencing heat indices exceeding 110°F (43.3°C).

Impact & Risks

The heat wave poses significant risks to public health, particularly for vulnerable populations such as the elderly, individuals with chronic illnesses, and those without access to air conditioning. Prolonged exposure to high temperatures and humidity can lead to heat exhaustion or heat stroke, which can be life-threatening. Urban areas are especially at risk due to the heat island effect, which can keep temperatures elevated even at night. Residents are advised to monitor their health and check on neighbors, especially those who may be more susceptible to heat-related illnesses.
