The Apple Fire is currently 95% contained and may remain so until winter precipitation arrives. Uncontained areas include steep terrain that is inaccessible to firefighters. Pockets of burning vegetation may also generate occasional smoke within the perimeter of the fire area.

Mudflow and flash flood risk

Recently burned areas are at a greater risk of mudflows and flash floods. Fires eliminate vegetation that can hold soil in place and charred ground may be unable to absorb water. Burned Area Emergency Response (BAER) efforts are focused on the protection of human life, safety and property. Rapid burn assessments identify areas that have increased potential for floods and mudflows. For more information, please visit the Apple Post-Fire BAER InciWeb page.

Incident background

The Apple Fire started in Cherry Valley, Calif., on July 31, 2020, due to a malfunctioning diesel vehicle. With dry vegetation and southwest winds, the wildfire quickly spread, eventually causing evacuations and reaching 33,424 acres. At the height of the fire, over 2,800 personnel responded and assisted on the incident. Much of the northern and eastern sections of the wildfire burned on very steep, rugged wilderness mountains that were not accessible to firefighters and vehicles.

The fire is burning in an area with no recent fire history. As the fire burns into the wilderness the fuels become decadent chaparral and timber that has experienced beetle kill on the ridge tops.

As it progresses east it will burn into areas where fuels are not as dense.
