A series of large-scale wildfires have rapidly worsened air quality in Southern California, raising health concerns for residents. Smoke from the fires spread across Southern California, including Los Angeles, Orange County, and San Diego County, on the 4th, causing air quality levels to reach hazardous levels.
The Gifford Fire, which raged across San Luis Obispo and Santa Barbara counties in Central California, has burned over 65,000 acres and remains at a very low containment rate.
According to the Purple Air Monitoring Network, fine dust concentrations in some areas on the morning of the 4th ranged from 50 to 100, with some areas exceeding triple digits.
Inland and mountainous regions are forecast to experience air pollution levels that are harmful not only to vulnerable populations but also to the public, compared to coastal areas. Health authorities are urging the elderly, children, pregnant women, and those with heart or respiratory conditions to be especially cautious and recommending preventive measures such as refraining from going outdoors and maintaining indoor air quality.
