The flames are threatening at least 100 structures, officials said.
“The fire is burning in dense chaparral and is being pushed by strong winds and growing at a rapid rate of speed,” a report on InciWeb said.
Winds in the area were recorded at 30-35 mph, with gusts up to 70 mph.
The blustery conditions forced all aircraft crews assigned to the fire to remain grounded due to unsafe flying conditions, fire officials said.
At least 125 crew members are assisting the firefighting efforts, according to a spokesperson at the sheriff’s office.
