A raging California wildfire has become the state's third-largest on record, with more devastation possible from a resurgence of the harsh winds that have fueled the deadly blaze since the beginning of the month.

The so-called Thomas Fire has destroyed more than 1000 structures, including about 750 homes, in Southern California coastal communities since erupting on 4 December, the state Department of Forestry and Fire Protection said in a statement.
The cause of the blaze is not yet known.
Authorities described the current conditions, including returning winds and extremely low humidity, as "critical fire weather."
Coastal Santa Barbara and more sparsely populated inland areas were of special concern, they said.
Mandatory evacuations were in place in several Santa Barbara County communities, including Carpinteria and Montecito, and parts of Ventura County. An evacuation order for the city of Ventura, which was hit hard in the first days of the fire, was lifted on Saturday morning.
The cost of fighting the blaze has already reached $US104 million, with more than 8000 firefighters working around the clock, and helicopters and airplanes dropping retardant on the flames.
"Each fire has a unique circumstance," California Fire spokesman Gabe Lauderdale said. "This one has impacted a lot of communities. The sheer size of the fire is what's unique about it."
For California, this year has been unprecedented in terms of structures lost and the size of the wildfires, Lauderdale said.
Five of 20 most destructive fires in recorded history ravaged the state in 2017, according to Cal Fire.
The Thomas Fire is only 40 percent contained, and it threatens 18,000 structures, officials said, including some in the wealthy enclave of Montecito just outside the city of Santa Barbara. The blaze is chewing up tall grass and bone-dry brush as it spreads along the scenic Pacific Coast.
The hot Santa Ana winds have propelled the fire's expansion, at times sending embers far ahead of its main flank.
They were forecast to remain strong through Saturday evening in the Santa Barbara County mountains, the National Weather Service warned. Gusts of up to 40 miles per hour (64 km/h) were expected.
