The Pickett Fire in California's Napa County grew Friday afternoon near Calistoga, reaching more than 3,000 acres, the largest fire in the Bay Area since last year.

A fire burning near Silverado Trail wineries prompted evacuation orders in Napa County. The Pickett Fire was reported around 3 p.m. on Thursday, Aug. 21, off Pickett Road, near Calistoga. By Friday afternoon, it had burned 3,235 acres (5 square miles) with 5% containment, the California Department of Forestry and Fire Protection said.

While California saw devastating wildfires in Los Angeles at the start of the year, the state has experienced an average summer fire season, with only one blaze, the Gifford fire, surpassing 100,000 acres. Fire activity is expected to pick up in coming days as the state bakes in a heat wave.
