More than 250,000 people have been forced to flee their homes to avoid three major blazes in the state.
Fire-fighters were powerless in stopping a wildfire destroying the northern town of Paradise, where nine people died and 35 are missing.
Another fire swept into the affluent southern beach resort of Malibu on Friday and has now doubled in size.
Two more people were reported to have died in that fire, known as the Woolsey, which now covers an area of 70,000 acres.
