Firefighters were battling a large brush fire burning in Kern County on Saturday. The blaze, which firefighters were calling the Little Fire, was first reported at 3 p.m. on Friday near Highway 178 and south of Lake Isabella, according to the U.S. National Forest Service .

The wildfire spread to more than 2,100 acres hours after erupting near Calistoga, authorities said. Evacuation orders were issued in parts of Napa County.

Evacuation orders are in effect as wildfires blaze across the West, including in California's scenic Napa County. The Pickett Fire, which has burned nearly 4,690 acres, first sparked Thursday afternoon and continued to rage Saturday with only 7% of the wildfire contained.
