Southern California faces unhealthy air quality due to wildfires and a heatwave, with the AQI expected to reach very unhealthy levels.

Southern California is facing unhealthy air quality due to ongoing wildfires and a heatwave. The Air Quality Index (AQI) is expected to reach very unhealthy levels, particularly in the San Gabriel Valley and San Bernardino County. Residents are advised to stay indoors, avoid vigorous activities, and use air purifiers. The Line Fire has burned over 20,000 acres with only 3% containment, exacerbating the air quality crisis. Health risks are heightened for vulnerable populations.
