(Redding, CA) – Today the August Complex North Zone began operations as two separate geographic areas. The dividing line between the Northeast Zone and the Northwest Zone is along South Fork Mountain through Pickett Peak to State Route 36, crossing SR 36 between mile post 55 and 56, continuing north following the South Fork Trinity River. Two zones will provide more supervisory personnel, increased oversight and improve the effectiveness of fire resources. Crews who have been working in the Ruth Valley will be the same to preserve that continuity.

Northeast Zone – Yesterday, northwest surface winds allowed smoke to clear over the western lake portion of the fire.  As the smoke “lid” was lifted, coupled with high temperatures and low humidity, fire activity increased along the perimeter north of SR 36. As those northwest winds interacted with the terrain over the east fire perimeter, southwest terrain driven winds carried spot fires over Forest Road 35 to the east towards Round Mountain and the area where Shasta, Tehama and Trinity Counties intersect. 

Fire crews will be assessing and providing structure protection in Wildwood and Platina. Those communities remain under an Evacuation Warning and should be prepared to leave immediately if an Evacuation Order is issued. Firefighters will look for opportunities to safely engage the fire above FR 35.

Crews will continue constructing dozer lines above SR 36 north of Forest Glen and on both sides of the South Fork Trinity River. Multiple contingency lines utilizing forest roads and old fuel breaks northwest of Post Mountain to South Fork Trinity River are being improved.  On the east fire perimeter, crews will hold and improve all existing control lines to keep the fire from spreading further beyond of SR 36.  

Northwest Zone - Personnel were reallocated from the South Zone to areas near Ruth Lake and the northwest area of the fire. Below South Fork Mountain, the fire has been slowly backing down towards containment lines to the northwest. Where crews cannot directly fight the fire due to terrain or safety concerns, they are using indirect techniques such as anchoring to road systems and using dozer lines for containment well ahead of where the fire is currently burning. Near Zenia the fire crossed existing dozer lines, but progress is being made to contain the fire’s growth with hose lays and crews.

Residents are not permitted entry into evacuated areas until the Sheriff lifts the orders. Public safety officers continue to enforce roadblocks for firefighter and public safety as well as property protection.

Smoke will again have an influence on today’s weather. Temperatures will remain 10 to 15 degrees above normal and relative humidity values will fall into the teens over the mid-slopes and ridges. Winds will not be as strong as yesterday and there will likely be variability with the terrain driven winds.
