Fuels Involved

Fuels include: Timber (Litter and Understory); Closed Timber Litter; and Brush (two feet)

Timber fuels with litter and understory throughout the fire area. Past fire footprints of varying age consist of grass and brush. Dead fuels are critically dry, with live woody fuels contributing to fire spread. Canopy moss is causing short range spotting.

Significant Events

Observed fire behavior: active, flanking, single-tree torching, short-range spotting

Active fire behavior on all fires is primarily driven by fuels and topography. Fire spread is mostly via backing and flanking. All incidents in the complex are demonstrating high resistance to control due to short-range spotting and rollout. As fires back off ridgelines they threaten high-use recreation areas, residences, infrastructure, and travel corridors. Small unstaffed fires within the complex have the potential to merge.

Outlook
Planned Actions

Direct attack suppression operations on Pig Iron, Lemolo, Watson, and Trail fires. Direct and indirect suppression tactics on the Pine Bench fire to keep it west of the Pacific Power and Light infrastructure and government housing. Point source protection of critical communication tower on the Watson fire.

Projected Incident Activity

12 hours: Smoke will settle into lakes and drainages. Good relative humidity recovery will reduce fire behavior to creeping and smoldering overnight.

24 hours: With warmer conditions on Tuesday active fire behavior will continue, primarily surface fire with single and group torching. Spread potential is high for ongoing incidents. There is also potential for new holdover incidents to be added to the complex. Fire spread threatens resorts and other high use recreation areas, as well as critical infrastructure. Smoke production will increase with expanding fire footprints.

48 hours: Active fire behavior will continue. Spread potential is high for ongoing incidents. Potential for new holdover incidents to be added to the complex. Fire spread threatens resorts and other high use recreation areas as well as critical infrastructure. Smoke production will increase with expanding fire footprints.
