California Gov. Jerry Brown declared a state of emergency in Lake and Napa counties Sunday, as the Valley Fire continued to bring pain and loss.
His announcement, which will help expedite debris removal and waive fees to replace essential documents like birth certificates for those who've had to abandon their homes and belongings, came one day after four firefighters were injured.
The firefighters were burned in the Valley Fire in Lake County, about 115 miles west of Sacramento. Cal Fire public information officer Daniel Berlant said on Twitter that they were transported to a Sacramento-area burn center for treatment.
"All suffered 2nd degree burns and are in stable condition at UC Davis Medical," he said. At least 1,000 firefighters were trying to battle the blaze, which began as a 50-acre inferno.
By Sunday, the fire had grown to some 50,000 acres.
Thousands fled this weekend as mandatory evacuations were ordered for the communities of Cobb, Middletown, Harbin Hot Springs and Big Canyon Road. More than 5,000 are without power, according to Berlant.
"As we came down, just fire everywhere and all of our houses, our neighbor's houses, our friends' houses -- everybody's houses are burning up. It's awful," Joyce Reim, who lives in Cobb, told CNN affiliate KGO.
The Butte Fire in Amador and Calaveras counties, about 70 miles east of Sacramento, has grown to 65,000 acres, Cal Fire reported. It has destroyed at least 85 residences and 50 outbuildings and threatens 6,150 homes.
"This fire has continued to grow at such a fast rate. It's threatening more and more homes," Berlant said Saturday on CNN. "With the dry conditions we have across California, this fire has been explosive in the size and just how quickly (it) has been able to grow."
Alexis Woodruff evacuated her family out of their house in Amador County, CNN affiliate KTXL reported.
"Losing everything you own and having to replace everything is a scary thought," she said.
Jamie Levingston came from another town to help move animals out of the fire zone.
"I would want help if it was my home," she told KTXL. "They're our neighbors. Of course, we're going to come and help."
About 3,300 firefighters are on the scene and about 100 officers and deputies from 23 agencies have responded to a request for mutual aid, Berlant said.
