The extreme heat wave is expected to significantly impact residents across Southern California, particularly vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Prolonged exposure to high temperatures increases the risk of heat-related illnesses, including heat exhaustion and heatstroke. Additionally, the heat may strain local power grids due to increased demand for air conditioning and could elevate the risk of wildfires in the region. Outdoor activities should be limited during peak heat hours to avoid health risks.
