The fuel materials include: mixed conifer of varying ages, decadent brush with no recent fire history, and a heavy dead and down surface fuels.

Significant Events

Observed fire behavior was minimal intensity and included flanking, backing, and creeping.

Firing operations were completed near Damnation Peak today. The fire continues to consume isolated pockets of unburned fuel within containment lines.

Outlook

Planned Actions

Hold previous firing operations, implement firing operations on indirect control lines as conditions allow, provide structure defense where necessary, continue mop-up along the fire perimeter, locate and document opportunities for suppression repair, patrol and stabilization of incident.

Projected Incident Activity

12 hours: Nighttime conditions will minimize fire heavier tonight. Islands of unburned fuels in the perimeter will burn in the presence of moderate to heavy surface fuel. Crews will continue to patrol the fire perimeter overnight where applicable and safe.

24 hours: Red Flag Warning for dry north winds and low relative humidity is forecasted, which could increase the risk of spot fires and may cause holding concerns for the south end of the fire. Rollout remains the prominent methods of fire spread. Islands of unburned fuels in the perimeter will burn in the presence of moderate to heavy surface fuel. Crews continue to patrol the western perimeter of the fire and where applicable. Mopup will continue progress deeper within the perimeter. Suppression repair is beginning in areas where the threat of fire escape has been mitigated.

48 hours: Reduced winds will return to moderated fire behavior. Interior pockets will continue to burn. Rollout remains the prominent methods of fire spread. Islands of unburned fuels in the perimeter will burn in the presence of moderate to heavy surface fuel. Crews continue to patrol the western perimeter of the fire and where applicable. Mopup will continue progress deeper within the perimeter. Suppression repair is beginning in areas where the threat of fire escape has been mitigated.
