Firefighters make progress on Airport Fire burning in Riverside and Orange counties

Firefighters Sunday continued to make progress on the Airport Fire, which has scorched more than 20,000 acres, in Riverside and Orange counties. 
The 23,519-acre fire, which erupted in Trabuco and Rose canyons last Monday, was at 19 percent containment, according to the California Department of Forestry and Fire Protection. 
At last count, the fire had destroyed 152 structures, damaged 31 others, and injured twelve firefighters and two civilians. Of the structures destroyed, at least 82 were believed to be homes. Another 20,780 structures remain under threat, authorities said. 
Overnight, the fire remained within its existing footprint, according to firefighters, who were also able to access previously inaccessible areas around Trabuco Canyon Road. Sprinkler protection was also implemented at Lazy W Ranch as a structure protection mechanism, and containment lines were being reinforced in Bell Canyon, along Trabuco Canyon Road, and in the canyon above Lake Elsinore. 
Evacuation orders and warnings remain in place, as seen below in the interactive map:
