Fuel moistures are historically low, ERCs and BI are in the 97-99%. Northern California remains under a Fuels and Fire Behavior

Advisory.

Active:

Wind Drive Runs

Group Torching

Short-range Spotting

Narrative:

The fire continued to progress to the north in the Lassen Park area and Caribou wilderness, with active torching, spotting and short intense runs. Other areas on the fire continued to smolder in the heavy fuels with single and group tree torching observed.

Smoke cleared early allowing surface winds to increase fire activity.

Construct direct and indirect line to secure fire perimeter. Direct line construction in the Westwood area will require a heavy resource presence.

Provide for service calls within communities impacted by the fire: Chester, Hwy 36 corridor, Hwy 89 Corridor, Hwy 395 corridor, Paxton, Greenville, Jonesville, Crescent Mills, Taylorsville, Prattville, Canyondam, Butte Meadows, Bucks Lake, Meadows Valley, Rush Creek, Warner Valley, Pecks Valley, Williams Valley, Hunt Canyon, Susanville, Janesville, and the Greater Almanor area.

Structure protection and heavy mop up continues in Warner Valley, Cradle Valley, and Wilcox Valley. Protect threatened areas of Janesville, Indicator Peak and Loan Peak. Heavy mop and patrol of communities impacted by the fire front. "Make Safe" for repopulation. Resources will be working from Dyer Mountain east to Mountain Meadow Reservoir utilizing direct line to complete action in that area.

Continued mop up of and patrol of 1,000-hr fuels will require a significant amount of resources due to the volume of fuels and the steep and rugged terrain.

Priority areas include Genesee Valley, Taylorsville, and the Janesville/Milford area, as well as continued holding of the Hwy 36 corridor and the Mill creek drainage. Fire is well established in the Mill Creek Plateau. Continue patrol of constructed line and prevent the fire entering Mill Creek drainage.

Resources in the Genesee Valley area continue protect the community of Taylorsville and limit spread from spot fires and active flanks. Resources continue to hold the Hwy 36 corridor and monitor for spots across the highway.

Continued holding actions and point protection of communities and critical infrastructure will require a significant resource presence for the next several operational periods.

Tactics that utilize fewer resources are being implemented in the Lassen Sector. Firing plans are being developed for West Zone

12 hours:

Southwest winds to diminish overnight and transition to a downslope and drainage aligned wind pattern. A wind reversal is expected on ridgetops with winds from the east. Thermal belts are expected to develop, with RHs not likely recovering above 35% on the mid-slopes.

24 hours:

An increase in temperature is predicted along with decreasing winds from the north and northwest. Dry conditions are expected to see RHs fall into the teens. Winds could become terrain driven in the afternoon.

48 hours:

Temperatures to be above normal through the weekend, with RH values possibly in the single digits. Expect an increase in fire behavior with the forecasted hot and dry weather.

72 hours:

Temperatures forecasted be in the mid to low 90's over the next few shifts. Expect an increase in fire behavior with the forecasted hot and dry weather.

Anticipated after 72 hours: Expect similar burning conditions. Temperatures will remain in the high 80's to low 90's throughout the week.

Continuation of Box 4: California Interagency Incident Management Team 1(CIIMT 1)is in command of the East Zone. East Zone Unified Command Agencies: Plumas National Forest and Lassen National Forest CAL FIRE IMT3 is in command of the West Zone. West Zone Unified Command Agencies: Bureau of Land Management, CAL FIRE, Lassen National Forest, National Park Service

Continuation of Box 25:

The fire area is in portions of Butte, Lassen, Plumas, Shasta, and Tehama counties. Active fronts are in the Greater Lake Almanor area, Lassen NF, and Lassen NP, as well as on several private timber ownerships.

Continuation of Box 31(J): Civilians in indoor temporary shelters - 30 Civilians in outdoor temporary shelters - 31

Continuation of Box 32(E): East Zone - 3 responder injuries West Zone - 3 responder injuries

Continuation of Box 33:

State of Emergency for Butte, Lassen, and Plumas counties was declared by Governor Newsom on July 23rd, 2021. Butte, Lassen, Plumas, and Tehama Counties have declared local emergencies.

FMAG has been approved for Butte, Plumas, and Lassen Counties.

The Plumas National Forest implemented Forest Order No. 05-11-00-21-18, effective from July 25, 2021, through September 30, 2021. The Lassen National Forest implemented Forest Order No. 06-21-07, effective from July 27, 2021, through September 30, 2021.

Continuation of Box 38: Additional values at risk threatened: National Scenic and Historic Trails: Pacific

Crest Trail, Bizz Johnson National Recreation Trail Inventory Roadless Area (IRAs): Bucks Lake (PNF), Butt Mountain (PNF), Chips Creek (LNF), and Cub Creek (LNF). Experimental Forests: Swain Mountain, Blacks Mountain. Research Natural Areas (RNAs): Green Island Lake (LNF), Soda Ridge (LNF), Cub Creek (LNF), Mount Pleasant (PNF).

Air Quality impacts: Reno, Carson City, Susanville, Sparks, Fernley and Quincy.

Airports impacted by TFR and smoke impacts: Rogers Field (Chester Airport), Ganser Field (Quincy Airport), Westwood Airport, Susanville Municipal Airport, Herlong Airport Wilderness: Bucks Lake Wilderness (PNF), Caribou Wilderness (LNF), Lassen Volcanic National Park Wilderness.

Commercial timber ownerships: Sierra Pacific Industries, W.M. Beaty and Associates, Collins Pine. An estimated $1 Billion dollars of timber has already been destroyed with an additional $1 Billion still threatened. Total cumulative private timber loss -260,724 acres. Substantial losses of private and public timberlands have released decades of sequestered carbon, releasing it into the atmosphere with

uncalculatable impacts to greenhouse gas accumulations.

Waterways: Philbrook Lake (PG&E, LNF), North Fork of the Feather River (PG&E, PNF), Silver Lake (Drinking water, PNF), Thompson Lake (Drinking water, PNF), Butte Creek (T&E species: chinook and steelhead, PNF), Deer Creek (T&E species: chinook and steelhead), Oliver Lake (T&E species: Sierra-Nevada Yellow-legged Frog, LNF), Gold Lake (T&E species: Sierra-Nevada

Settled valley smoke diffused steadily throughout the day. Southwest winds increased to 10-15 mph with gusts of 25 mph. Temperatures were in 70s to lower 80s. As the upper-level trough moves east Thursday, temperatures are expected to increase. Winds from the north to northeast are anticipated Friday and

Saturday. These winds are predicted to be light and mainly terrain driven.

Temperatures are forecasted to be above normal through the weekend, with very dry air. This dry air and warmer temperatures could lead to single digit RHs.

Potential still exists for plume dominated fire behavior with alignment of fuels, topography, and extremely dry fuels.
