The Silver Fire burns on Thursday evening near Cabezon, California. In the foreground are windmills used to generate electric power in the area due to the frequent high winds found at the Banning Pass.
Officials in California on Sunday said they have gained the upper hand on a wildfire that has burned across more than 30 square miles over the past four days. They said they expect to have the Silver Fire fully contained by Monday.
The Silver Fire was at 19,436cres and 75 percent containment Sunday morning, according to fire officials, NBC Los Angeles reported.
Since starting on Wednesday afternoon, the blaze has injured six firefighters and one civilian, and destroyed about four dozen structures, according to the report.
"It hit here really fast. That wind started, started pushing the fire over that ridge line. Before they knew it, it was upon the community," Julie Hutchinson, a spokeswoman for the California Department of Forestry and Fire Protection, told NBC News.
More than 2,000 personnel are on the scene, including 68 fire crews, according to the Riverside County Fire Department.
Local resident Dave Matthews said he had lived in his house for a decade until the flames swept up and devoured it within minutes.
"I talked to a couple of the firefighters and they said the house across from me, next door to me, was fully engulfed," Matthews told NBC News.
Firefighters told Matthews that there was nothing they could do to save his home, he said.
Another area resident, Dave Clark, said he watched his home burn down.
"I got here and the house was already half burned," Clark told NBC News. He scrambled to save what he could as the flames licked up his home.
"I knew where a bag of legal documents were, so I ran in and grabbed them and ran out," Clark said.
California Gov. Jerry Brown declared a state of emergency Friday for Riverside County in the wake of the fire so that victims may be eligible for federal disaster assistance, NBC Los Angeles reported.
Evacuation orders were also set in place, but have since been lifted by the Riverside County Sheriff's office.
The cause of the fire is under investigation.
