The heat index values in the middle 100s (°F) pose a significant risk of heat-related illnesses, particularly for vulnerable populations such as the elderly and outdoor workers. Thunderstorms with gusty winds and frequent lightning may disrupt outdoor activities and pose localized hazards. Rip currents along the East Coast beaches and the Panhandle present life-threatening conditions for swimmers. Flash flooding in Northeast Florida and the Western Panhandle could lead to localized water accumulation, especially in low-lying areas.
