The heatwave poses significant risks to vulnerable populations, including the elderly, young children, and those without access to air conditioning. Outdoor workers and individuals engaging in strenuous activities are also at heightened risk of heat-related illnesses. Elevated fire risks are expected due to drying fuels and windy conditions, particularly in valleys and mountainous regions. Additionally, air quality in parts of Los Angeles County is forecasted to range from 'unhealthy for sensitive groups' to 'very unhealthy,' exacerbating health risks for individuals with respiratory conditions.
