The primary carrier of fire at lower elevations is grass and shrub mix with areas of timber litter. In the mid to upper

elevation the fuels are heavy forest litter with shrubs and small trees. There are pockets of heavy dead and down.

Minimal

Creeping

Smoldering

The humidity recovery continues to be reduced overnight allowing for more active fire behavior. The fire continues to burn heavy material and burning interior pocket of fuel. Single tree torching continues to be a possible source for short range spotting. The ground fuel are staying more active allowing for more flare ups in the canopy.

Priority areas include: the Lassen & Shasta Sectors, Old Station and surrounding communities, the highway 395 escarpment area including Janesville, Milford and Herlong Junction as well as Lake Davis and the Grizzly Creek area west of the escarpment.

Continue to establish direct and indirect containment lines south of Old Station. Resources continue to establish containment lines north of Hwy 44 in the vicinity of Hat Creek Rim and Plateau as well as protecting critical fiber optic infrastructure.

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, Butte Meadows, Bucks Lake, Meadows Valley, Rush Creek, Warner Valley, Pecks Valley, Williams Valley, Hunt Canyon, Susanville, Janesville, and the Greater Almanor 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. Continued holding actions and point protection of communities and critical infrastructure will require a significant resource presence for the next several operational periods.

East Zone priorities:

1) Patrol direct line in the Devil's Punchbowl area.

2) Resources will continue to mop up dozer and handline from Lake Davis to Clover Valley and mop up dozer and handline further south into Dixie Valley, as well as south towards Clover Valley and Portola.

3) East of Milford, patrol and mop up containment lines on the NW flanks of the fire south from Highway 395.

4) Maintain containment, mop-up, and backhaul of equipment on western and central divisions in the Zone. Structure protection is in place within Genesee, Dixie Valley, Lake Davis area, Milford, and Taylorsville.

12 hours: Weather was calm with clear skies. Temperatures dropped overnight to mid 30s to mid 40s at higher elevations and in the low 50s in valleys. RH recovery was moderate to 40- 50%, but drier than last night. Light downslope/downvalley winds occurred overnight.

24 hours: (Mon) A slight warming trend with a little lower humidity. Wind will be relatively light, shifting to the northwest with afternoon gusts around 15 mph. Smoldering, creeping with some surface activity possible as the day warms and dries along with the gusty winds.

48 hours: (Mon night and Tue) A clear night and mostly sunny day is expected. Wind will be the lightest of the week, with gusts staying at 15 mph or below. Warming and drying out continues for both overnight and afternoon. Temperatures top out today for the week, with some temperatures getting to the low 90s. Lower humidity is expected with decreased recovery and many locations getting below 15 percent for the afternoon. Minimal to moderate fire activity as fuels dry out from the recent precipitation. Needle cast fuel beds will support surface fire but low intensity in areas that underburned.

72 hours: (Tue night and Wed) Temperatures remain very warm, with some temperatures in the low 90s. Humidity remains low, with many locations getting below 15 percent for the afternoon. Minimal to moderate fire activity as fuels dry out from the recent precipitation. Needle cast fuel beds will support surface fire but low intensity in areas that underburned. Potential for some torching trees will increase the chances of short range spotting. Anticipated after 72 hours: Quiet weather persists with no significant weather expected. Temperatures will stay cooler through the week. However, conditions will continue to dry with no rain in the forecast this week. Expect minimum relative humidities to drop into the teens each afternoon with increasingly poor recoveries overnight. Winds will stay light with variation in general wind direction. Some slightly enhanced wind speeds may occur later in the week with some weak weather disturbances passing by.

Box 4: Transfer of command from CAL FIRE IMT1 to California Interagency Incident Management Team 14 (CAIIMT 14) will occur 0700 hours 9/13/2021.

Calm weather again today with highs low 70s to low 80s depending on elevation. Skies were mostly clear, save for a few cumulus clouds developing this afternoon. This allowed for more drying, which dropped relative humidities to 10-15%. Winds were mainly terrain driven, with a light southwesterly general wind of 5-10 mph. Some gusts to 15 mph were recorded. Overall, fair weather.

Box 33: A 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 the Dixie Incident. Regional Order No. 21-07, effective August 31, 2021 through September 17, 2021, closes National Forest System lands within the Pacific Southwest Region inclusive of Plumas and Lassen NF's. 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.

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).
