The extreme heat poses significant risks, particularly to vulnerable populations such as the elderly, children, and outdoor workers. Prolonged exposure to high temperatures can lead to dehydration, heat exhaustion, or heat stroke. Residents in the Coachella Valley, San Gorgonio Pass, and San Diego County Deserts are urged to take precautions, as these areas are expected to experience the most severe conditions. Emergency alerts will be sent for considerable or catastrophic hazards, and residents are encouraged to monitor local updates.
