LA County Supervisor Kathryn Barger, who represents the area, urged residents to heed evacuation guidelines.
“The #CanyonFire is spreading fast under extreme heat & dry conditions near Ventura-LA County line,” Barger wrote on X.
“If you’re in Santa Clarita, Hasley Canyon, or Val Verde, take evacuation orders seriously — when first responders say GO, leave immediately. Keep aware – please don’t risk lives.”
The fires follow a July blaze that scorched more than 28,300ha and needed hundreds of firefighters to contain it.
Fire authorities at the time noted that dry brush, sustained winds and high temperatures were fueling the flames.
That came after several earlier fires, stoking fears of a difficult season in a state still reeling from wildfires that killed 30 people in January.
Earlier this week, Zurich-based reinsurance giant Swiss Re said natural disasters caused US$135 billion in economic losses globally in the first half of this year, fuelled by the Los Angeles wildfires.
