LOS ANGELES (KABC) -- Three wildfires burning in three Southern California counties are growing quickly as firefighters work to contain the blazes.
The Line Fire erupted last week and has burned more than 37,000 acres through rough mountain terrain in the Highland area of San Bernardino County. One person has been arrested for allegedly starting the fire.
The Airport Fire in Orange County has grown to over 23,412 acres after since it was accidentally sparked by county public works crews who were trying to move boulders in the area.
The Bridge Fire in the Angeles National Forest has charred more than 51,100 acres since it erupted Sunday. It has destroyed more than 30 homes in Mount Baldy and Wrightwood.
A brush fire ignited in a Los Angeles County high desert community on Tuesday afternoon.
The fire, called the Apollo Fire, is burning near 245th Street and West Aqueduct Road in Fairmont.
The L.A. County Fire Department said the blaze has consumed 60 acres so far.
The fire fight continues from the ground and the air. The National Guard arrived in San Bernardino County to work alongside more than 2,000 firefighters.
Highway 330 in Highland, which is closed to the public, is one of the main roads being used to get resources up into the mountains.
The Line Fire has now grown to 26,516 acres, with containment at 5 percent. More than 38,000 structures are threatened.
Cal Fire said crews made good progress overnight thanks to better weather conditions. But the biggest concern on Tuesday is still the heat.
The blaze is burning to the north and east. More resources are on the way, but another challenge is a red-flag warning that was issued for the area.
The massive fire has grown larger in size, burning 26,426 acres of mostly rough mountain terrain in San Bernardino County. Fire crews did not increase the containment of the flames overnight.
The California National Guard was activated to support the ongoing response to the Line Fire in San Bernardino County, Gov. Gavin Newsom announced.
The Guard will deploy a slew of resources, including four UH-60 Blackhawk helicopters for water-dropping operations and hand crews.
