The high heat index poses risks of heat-related illnesses, particularly for those spending extended periods outdoors. Coastal areas may experience even higher heat indices, reaching up to 109°F (43°C). Outdoor activities, including after-school sports practices, will require precautions such as staying hydrated and taking breaks in shaded or air-conditioned areas. Flood warnings are currently in effect for Live Oak and McMullen Counties, though these are unrelated to the heat.
