The fires raging in San Diego County underscore an unprecedented fire season underway in California.
Since the start of this year, Cal Fire has already fought about 1,400 wildfires across the state -- more than twice the average number for this time of year, Cal Fire spokesman Daniel Berlant said.
"It starts with the drought," Berlant said. "The grass, the brush and the trees -- not only in San Diego County, really across California -- are really dry."
The drought and increase in fires prompted Cal Fire to keep the same number of firefighters, helicopters and equipment in Southern California usually reserved for fire season in the fall.
"Fire season from 2013 rolled right into 2014 and continues with no end in sight," Berlant said.
