USDA Forest Service and CAL FIRE are engaged in a coordinated response to manage and suppress the August Complex.  The Complex has been divided into three zones; North, South and West.  Geographically, the North Zone is in the northern area of the Mendocino National Forest in the Yolla Bolly Wilderness; near Tomhead Lookout on the Shasta-Trinity National Forest; and in the northwest near Kettenpom Valley and the Flying AA Ranch on the Six Rivers National Forest.

Current Situation (August Complex-North Zone): Conditions today will be dry, windy and with less smoke which will influence fire behavior. The priority in the North Zone is structure protection, indirect line construction (away from the fire’s edge) and tactical firing operations (applying fire on the ground to remove vegetation and widen containment lines).

In Ruth Valley, south of Ruth (Six Rivers National Forest), the fire has become established above the Ruth Community Church and northeast of Horse Ridge Lookout.  As the fire continues to move northeast, firefighters will engage and do structure defense around the homes along the Ruth Lake Road.

On the west perimeter of the fire (Zenia Area), dozers are being used to construct indirect lines on Road 3S09 to Zenia Lake Mtn Road (3S21).   Crews are working to complete hand lines to the Middle Fork of the Eel River. 

On the northeast perimeter (Shasta-Trinity National Forest), the 35 Road continues to be an important strategic containment line to stop the progress of the fire. Crews continue working from Rat Trap to the east, improving the line and using tactical firing operations. The east perimeter near Red Bluff is in mop-up and patrol status.  A ten-person crew of smokejumpers will be utilized on the north portion of the fire to assess historic structures in the area.

Weather:   A trough of low pressure will bring gusty south-southwest winds over the area.  The winds combined with the low relative humidity will create elevated fire weather conditions.

Smoke Outlook: Air quality remains unhealthy in many areas, with very unhealthy air overnight in foothill areas strongly affected by settling of down drainage smoke. Slightly stronger southerly winds may bring some gradual improvements today, with southwesterly winds continuing the slow clearing trend tomorrow.
