The fires that began earlier this week may have caused at least one death. Firefighters found a charred body Thursday in the remains of a homeless encampment in Carlsbad in northern San Diego County.
At least 10 fires were burning Friday morning, officials said. The Cocos fire, although much smaller than the two burning at Pendleton, was described as the most active.
The fires have been spread by the area's Santa Ana winds, which blow hot dry air from inland areas downhill towards the coast. But officials say some of them may have been deliberately set.
Two teenagers were arrested late Thursday in Escondido as they attempted to bicycle away from police. They are suspected of setting small fires in the city.
The Poinsettia fire in Carlsbad has destroyed about two-dozen single-family homes and apartments. The Cocos fire, barely contained Friday, has gutted buildings in San Marcos, east of Carlsbad.
James Harkins told the Los Angeles Times his San Marcos neighborhood is now a "moonscape."
"There ain't nothing here," he said. "Just white ash and white ash and white ash."
At Camp Pendleton, hundreds of people have been forced to evacuate base housing or leave their work stations. As of Friday, no buildings had burned and no serious injuries reported.
The Las Pulgas fire on the base itself has burned across 8,000 acres, while the Tomahawk fire at Naval Weapons Station Fallbrook had charred more than 6,000.
