A raging wildfire in Napa County continued to threaten hundreds of structures Wednesday night as several other fires broke out in parched vegetation in Central and Northern California.
The fire broke out Tuesday afternoon off Butts Canyon Road in Pope Valley, northwest of Lake Berryessa.
In the Sequoia National Forest, the Ranch fire had burned about 150 acres Wednesday night in rugged terrain about 200 miles northeast of Bakersfield, the U.S. Forest Service said.
High temperatures and low relative humidity were complicating the battle to contain the blaze. About 200 firefighters, aided by helicopters and fixed-wing aircraft, were attacking the fire earlier in the day.
In Northeastern California, lighting strikes sparked several smaller fires in heavily forested areas, fire officials said. Forest Service smoke jumpers and hotshot crews were being called in to fight the fires.
The blazes broke out as high pressure was causing hot weather across California, according to the National Weather Service.
