More than 1,000 firefighters are working the Butts Fire in Napa and Lake counties. The fire is 4,300 acres and 30 percent contained.
CalFire spokesman Dan Berlant said evacuations have been lifted along Butts Canyon Rd. north to Snell Valley Rd. But an Evacuation Advisory is in effect for residents in Lake County on Butts Canyon Road from the Lake County line to Langtry Estates.
The evacuation center is located at the Middletown High School in Middletown (Lake County).
Berlant said the Butts Fire is one of six large fires burning Thursday in California.
"Definitely been a very busy day [Thursday] for us across California with the dry conditions we're experiencing fire activity has been very high lately,” said Berlant.
He said the agency has increased staffing.
"We’re putting additional firefighters on duty, staffing reserve equipment and making sure we have plenty of equipment," Berlant said.
Along with 1,067 firefighters on the Butts Fire, an additional 1,000 state and federal firefighters are working wildfires in San Diego, Kern and Modoc counties.
The Banner Fire, east of the mountain town of Julian in San Diego County, has caused evacuations. Two homes have burned and 200 are threatened, according to CalFire.
