As weary firefighters battled stubborn brush fires for a fourth day Friday, billowing black smoke drifted northward, causing health warnings throughout much of Southern California.
By mid-afternoon, the air hanging stagnantly over Los Angeles was considered "unhealthy" by the South Coast Air Quality Management District, triggering an advisory for anyone outdoors to avoid prolonged strenuous activity.
Four of the five regions in the nation with the worst air quality Saturday are forecast to be in California and Arizona — all affected by the brush fires in northern San Diego County, according to AirNow, a website that combines data from county, state and federal air-quality agencies nationwide.
After days of Santa Ana winds pushing the smoke and ash out to sea, a pressure system has reversed the wind, sending smoke back toward land, according to the National Weather Service.
Meanwhile, the 11 fires that began with the Bernardo fire Tuesday in San Diego have now burned nearly 20,000 acres, county officials announced late Friday.
Of those 11, four still were not contained: the 2,520-acre Cocos fire in San Marcos, the 1,550-acre Bernardo fire and two fires on military bases on the northern edge of the county.
Hundreds of people are still under mandatory evacuation orders near the Cocos fire, which has spread to Harmony Grove and Elfin Forest, and east to Escondido.
Officials have listed only three structures as destroyed but that number will increase when a fuller tally is released. The Poinsettia fire in Carlsbad, now contained at 400 acres, destroyed eight single-family homes and an 18-unit apartment complex.
The largest fires still uncontained are the 8,000-acre Las Pulgas fire at Camp Pendleton and the 6,500-acre Tomahawk fire at the Naval Weapons Station Fallbrook adjacent to Camp Pendleton.
