More than 2,000 fire personnel are on scene Monday as the Pickett Fire continued to burn in California's Napa County for a fifth day.

Pickett Fire, which began on Aug. 21, has spread to more than 6,800 acres through Napa County, just east of Santa Rosa, as of Aug. 25. The fire is 13% contained, and its cause remains under investigation, according to the California Department of Forestry and Fire Protection (Cal Fire).

Napa County officials in the span of two days have declared local emergencies in response to the Pickett Fire, one of which frees up resources to help tackle the roaring blaze.
