Five zones in Los Angeles County are under evacuation orders, with 2,700 residents evacuated and 700 structures threatened by the flames, officials said. Six other zones in this county are currently under an evacuation warning, with 1,400 residents and 5,000 structures at risk, officials said.

The fire has scorched an estimated 5,400 acres north of Los Angeles, but Ventura County officials said firefighters were making “good progress in suppressing the blaze.”

California officials warned of hot, dry weather that could contribute to “rapid” fire growth and “significant fire behavior.”
