Amid high temperatures, a wildfire was moving northwest in Los Angeles on Sunday after having burned more than 35,000 acres (about 14,175 hectares), authorities said.
About 2,000 firefighters were deployed to prevent the Station Fire from destroying more homes, the Los Angeles County Fire Department (LACFD) said.

The firefighters were assisted by water- and fire-retardant-dropping helicopters and fixed-wing aircraft, including a DC-10 jumbo jet, which can dump up to 12,000 gallons of fire retardant in eight seconds, according to the department.
The fire is about 5 percent contained, with full containment not expected until Sept. 8, said the department. How the fire started has not been established.
Three homes and about 30 cabins in the Angeles National Forest have been destroyed, with 10,000 other foothill homes and some 2,000 commercial buildings threatened, firefighters said.

Three civilians have been hurt -- two in the Big Tujunga Canyon area and one off Highway 2 near Mount Wilson.
With temperatures expected to reach the mid- to high 90s Fahreinheit on Sunday in the fire areas, officials said they were expecting extreme fire conditions, mirroring Saturday's, when flames leapt as high as 80 feet and spread at a rate of about 2.5 miles (four kilometers) an hour.
The fire is also threatening the Santa Clarita Valley, broadcast facilities on Mount Wilson and the Jet Propulsion Laboratory in La Canada Flintridge.
