In Southern California, crews working through the night stopped the spread of two Los Angeles County fires that burned several structures, charred hundreds of acres of dry brush and led to the arson arrest of one person.
A brush fire sparked near a riverbed in Montebello, a suburb east of downtown Los Angeles, halted operations at an oil field and prompted the evacuation of a park. The fire, which grew to about 200 acres, was 20 percent contained Monday.
To the north, a wildfire that burned buildings at an abandoned rehabilitation center in rural Castaic has charred about 300 acres in Angeles National Forest.
Meanwhile, mechanical problems prompted Cal Fire to ground a fleet of planes Monday that help direct other aircraft where to dump retardant on wildland blazes.
Cal Fire ordered its fleet of 15 OV-10 A Broncos not to fly Monday after a propeller on one of the planes failed while the aircraft was still on the ground, according to Cal Fire Battalion Chief Scott McLean.
Five of the aircraft were later cleared for flights after passing safety inspections, he said.
