Hundreds have been forced to flee their homes as wildfires rage near California coast north of Los Angeles.
It marks a fierce start to a fire season in California that weather forecasters predict will be worsened by a summer of high temperatures and drought throughout much of the US West.
The largest of the blazes erupted about 6:30 am, less than 10 miles inland from the Pacific coast, and quickly consumed 6,500 acres of dry, dense shrubland near the communities of Camarillo and Newbury Park, about 50 miles north of Los Angeles.
More than 500 firefighters were dispatched to battle the blaze, along with six water-dropping helicopters.
Airplanes equipped to drop payloads of fire-retardant chemicals were grounded by high winds and thick smoke in the area, officials said.
Several farm buildings and recreational vehicles were engulfed in flames as the fires spread.
Fire department spokesman Tom McHale told KTLA-TV that authorities were worried people could be exposed to toxic fumes that might be released from agricultural facilities.
