A Southern California wildfire burning through coastal wilderness has nearly doubled in size since morning, growing to more than 28 square miles.
Ventura County fire spokesman Bill Nash says the 18,000-acre fire is burning new fuel in mostly unpopulated canyons.
He said it is 20 per cent contained.
The fire was estimated to have burned about 15 square miles as of early Friday morning.
The wind-whipped fire erupted Thursday in the Camarillo area, threatening as many as 4,000 homes but only damaging 15.
After burning to the Pacific Ocean, a shift in winds caused the flames to reverse course and burn inland.
No injuries have been reported.
