Fuels Involved

Fuels in the area are primarily composed of Shrub (SH7) Timber Litter (TLS) and Timber with Understory (TUS). Primary tree species include mixed sizes of Douglas Fir, Ponderosa Pine, and incense cedar. Heavy fuel concentrations are common throughout all areas. A transition of the fuels/vegetation from closed timber (less than 4000') to open timber, and a shrub component (greater than 4000') Douglas-fir canopy heights range from 60-100 ft height.

Significant Events

Fire area had good humidity recovery last night. The RHs may drop to low to mid 20s in the valleys and sun exposed south slopes. Smoldering and minimal creeping was the dominant fire behavior, with isolated incidents of backing fire through surface fuels. South facing and other slopes with sun will continue to dry out and the topmost needles may soon be available to burn. Roll outs from fallen burned snags and logs may result in reburn but movement will be minimal.

Outlook
Planned Actions

Div A: Patrol and mop up all potential heat that may threaten control features. Remove and backhaul flagging and signage. Continue suppression repair along Stuart Fork Trail.

Div M: Patrol from air. Utilize aircraft for bucket work as needed.

Div Z: Patrol and mop

Projected Incident Activity

12 hours:
Cool temperatures 45-55 with fair humidity recovery, drier than previous week. Heavy fuels will continue to remain available for consumption. Areas of isolated smoldering will continue, but surface movement is not expected.
24 hours:
Mostly sunny, hazy with smoke in the morning, light W winds, high temperatures 68-74 with the dry pattern staying in place, relative humidity 20-36%. Fire behavior will continue to be dominated by smoldering and creeping. The is a chance of some minimal movement of fire through surface litter. Temperatures will warm with a modest lowering of RH. Heat and smoke observed on the fire will be from heavy dead and down fuels smoldering. Roll out logs could be a hazard but there is little chance of them starting new fires.
48 hours:
Sunny with humidities into the 20-35% range, temps from high 60's to mid 70's, and no chanceof rain. Winds moving to a more marine influenced west direction with a slight increase in relative humidity. Wind sheltered slopes with RHs dropping below 25% will be a concern. Fire activity will continue to be predominantly smoldering with isolated areas of creeping fire and possible isolated surface movement. Overnight RH will be a little higher with humidities in the 55-75%. Highest chance of rollout is along Little Salt Creek in DIV M with some limited chance along the Stuart Fork trail. Reburn of areas now covered by fallen leaves and needles is a slight possibility.
72 hours:
Conditions continue to be seasonable with a slight increase in relative humidity, with no chance of precipitation. Winds out of the West to 8 mph. An increase in possible fire movement, smoldering of heavy fuels and creeping in litter under dense canopy, with the chance of some new smokes popping up during this period. Highest chance of rollout is along Little Salt Creek in DIV M with some limited chance along the Stuart Fork trail. Reburn of areas now covered by fallen leaves and needles is a slight possibility.
 

Remarks

Intel from Divisions and Planning OPS confirmed an increase in contaiment to 87%. In item 49, Resources, the fire modules are listed under Support. The REMS has no category in the 209 so they were placed under ALS Ambulance--(1) REMS with 4 people.

Current Weather
Weather Concerns

Seasonably mild and dry conditions will continue into the middle of the upcoming work week. In addition, no rain is expected during this period. Otherwise, winds will become locally gusty out of the west-northwest through east-west oriented valleys and gaps during the afternoon, while sheltered areas will generally experience light and variable winds. Relative humidities have been dropping at the Trinity Center RAWS--RHs have dropped from 32% on 9/06/23 to 16% on 9/10/23. This may be a concern for sun exposed fuels where smoldering and creeping is present.
