JULIAN, Calif. -- A wildfire destroyed two homes, threatened hundreds more and forced the cancellation of a Fourth of July parade and celebration in a historic gold-mining town in San Diego County.
The blaze that broke out Thursday near the mountain town of Julian was one of several burning across the state, including one in Northern California's Napa County that had also burned two homes and had grown to more than 6 square miles.
The San Diego County fire erupted around 10:30 a.m. and prompted the mandatory evacuation of 200 homes in nearby Julian. The evacuations were canceled by the end of the day.
Firefighters made progress overnight, increasing containment from 15 percent to 40 percent by early Friday, according to the California Department of Forestry and Fire Protection. The blaze also increased in size from 150 acres to 217.
As firefighters battled the blaze on the ground and aboard air tankers and water-dropping helicopters, sheriff's deputies cleared residents out of Kentwood-in-the-Pines and Whispering Pines, reported Matt Johnson of CBS affiliate KFMB.
But the threat to homes remained and the city planned to take the year off from its festive Fourth of July celebration that usually draws from 3,000 to 5,000 people.
"It's a big day for Julian," Michael Hart, publisher of local paper The Julian News told U-T San Diego.
The same area near Cleveland National Forest is where an 11-square-mile blaze destroyed more than 100 mountain cabins just a year ago.
Meanwhile, the fire in Napa that broke out Tuesday raced up steep and rugged terrain, forcing firefighters to build containment lines without bulldozers, said Alicia Amaro, a spokeswoman for the California Department of Forestry and Fire Protection.
The blaze had scorched more than 4,300 acres by Friday morning. It has damaged nine structures, including the two homes.
The fire was burning to the north, away from the county's famed vineyards.
Residents in nearly 200 homes in a subdivision in the county's Pope Valley were allowed to return after an evacuation order was lifted Thursday afternoon, but 180 other homes remained threatened, state fire officials said.
Crews won 55 percent containment of the blaze by early Friday, up from 30 percent on Thursday, thanks to favorable weather conditions that allowed crews to burn away fuel on the fire's Lake County flank.
Neither fire has led to any injuries. The causes of both remained unknown.
