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.

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.

The Pickett Fire near Calistoga has burned at least 3,235 acres with 7% containment, Cal Fire said late Friday afternoon.
