Flames from a wildfire engulf trees near Oroville, Calif., on Saturday, July 8, 2017.
Wildfire is on the increase so far this year, with more than double the number of acres burned compared to the same time last year, Head said. The wildfire is the largest now burning in California, after tripling in size over the weekend due to low humidity and persistent winds.
The newest fire, the Wall fire, southeast of Oroville, has charred at least 10 structures and has threatened thousands more. An inspection team is trying to determine the extent of the damage. Most of those evacuations remain in effect, though Wilsey and some others have been allowed to return home.

Schori said 1,700 people had been repopulated and that plans were in place to get more people back into their homes pending sign off from fire officials. He also said it's possible that removing the flag was a preventative measure: With the waving fabric so close to the house, it would only take a few embers blowing in the wind for the flag, and the home, to catch fire. The fire has burned at least 17 structures, including some homes in the Oroville area - a community about 70 miles north of Sacramento. They later saw photographs of their home burned to the ground.
