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.

With smoke advisories extended and evacuation orders still in place, damage inspectors are assessing whether homes or buildings have been lost.

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).
