UPDATE at 11:29 on August 13
The incident personnel have release some additional information about the fire, putting the best spin possible on the gains the crews made:
Progress was made on the fire lines yesterday and last night. With aggressive firefighting efforts and lighter winds, the fire burning above Cayuma Valley is still holding near the edge of the forest. Last night, a small slop over occurred in the headwaters of Pine and Buckhorn Canyons, and the sheriff evacuated 10 homes located in the lower end of those canyons.
Today, crews will focus on securing line around the northeast flank of the fire, which includes the new slop over area in Pine and Buckhorn Canyons, and to secure the fire line above Cayuma Valley.
Last night the Martin Mars air tanker, which holds up to 7,200 gallons of water, made its first drop on the fire. The Martin Mars is expected to continue working on the fire today, drafting water out of San Antonio Reservoir.
Here is a map of the La Brea fire showing the fire perimeter from early Thursday morning in red and the perimeter from early Wednesday morning in green. The national forest boundary is in light green. We are looking northwest.
