PALMDALE, Calif. (AP) _ A huge wildfire in the high desert wilderness north of Los Angeles jumped an aqueduct on Friday, rushing toward hundreds of houses as firefighters also tried to keep flames from damaging power lines that bring electricity to Southern California.
Some 2,000 structures were threatened and 300 homes were evacuated, Governor Arnold Schwarzenegger said.READ MORE: San Francisco Sees 3,000 Car Break-Ins in 1 month; 'It's Out of Control'
Winds apparently carried embers across the wide concrete channel, with flames rapidly spreading to backyard fences at the edge of Palmdale. Plumes of smoke streamed across the city of 139,000 as a predicted afternoon increase in winds finally arrived.
Helicopters dipped buckets into the aqueduct to make rapid water drops. No homes immediately appeared to have been damaged. Numerous fire engines were in the area. A giant Boeing 747 supertanker arrived over Palmdale to join the battle.
“As you see, we are deploying everything that we’ve got,” Schwarzenegger said at the fire command post.
Sustained winds of 10 mph to 20 mph were reported, said Los Angeles County fire Inspector Matt Levesque.
“We are actively moving resources to defend that area,” he said.
Most of the homes in the area, however, are of recent construction with fire resistant roofs, stucco walls, boxed eaves and landscaped with fire-resistant vegetation, he said. No evacuations were ordered but were recommended.READ MORE: At-Risk Veteran Missing In Alameda; Police Seek Public's Help
Temperatures neared 100 degrees with single-digit relative humidity and the National Weather Service predicted gusts in the area up to 50 mph Friday night. The fire has burned more than 20 square miles since erupting Thursday afternoon and was 20 percent contained, Schwarzenegger said.
Elsewhere in the battle, aircraft bombarded flames on ridges above the Antelope Valley on the southern edge of the Mojave Desert, while 750 firefighters working in high heat sought to outflank the blaze no matter which way it moved.
“We want to pinch it off and call it done,” Los Angeles County fire Capt. Andrew Olvera said.
The blaze spread rapidly after breaking out at midafternoon Thursday, triggering overnight evacuations of about 2,000 homes in rural areas and down to the western side of Palmdale.
One house and three mobile home residences were destroyed, another house had roof damage and various other outbuildings and garages were lost in the horse country region, authorities said.

Southern California Edison said the fire threatened five high-voltage transmission lines, but the California grid operator had put additional generation resources online and customers were not expected to be affected if the utility lost those lines.
