Firefighters on Friday night were gaining the upper hand on a brush fire in Simi Valley that had threatened hundreds of home in the area, officials said.
The Rustic Fire, burning in the 500 block of Rustic Hills Drive (map), had destroyed about 189 acres by 8:30 p.m. but was 50 percent contained, according to the Ventura County Fire Department. It began before 3:45 p.m.
"We're extremely busy here in Ventura County," said county fire Capt. Barry Parker. "The weather is extremely critical at this point, and resources are extremely thin."
More than 185 personnel were working on the blaze, which at one point was threatening about 500 homes, Parker said.
The Fire Department was working with Simi Valley police on a plan for possible evacuations, Parker said.
While officials did not order any evacuations, they had warned people to be ready to leave at a moment's notice.
Public safety was the chief concern, Parker said.
"We want to keep the fire away from the structures. There's numerous areas burning in different directions," the captain said.
Simi Valley police called the fire a "dangerous situation" for residents, and warned people to stay away. Residents were told to shelter in place. The impacted area was described by police as "neighborhoods that interface the wild land areas south of Long Canyon Road."
"I was on the telephone with my work, and I looked out the window and there were flames very, very close actually," said resident Chris Menefee, who lives in the Wood Ranch area.
Another fire burned 3 to 4 acres at the nearby Rustic Hills golf course in Moorpark, Lindbery said on Twitter.
The blazes came on a day of extreme heat that saw a wildfire in the Angeles National Forest burn at least one structure.
