Status Updates

(Redding, CA) – Wind gusts continue to push the fire west, prompting evacuation orders to the Trinity County line and evacuation warnings in Humboldt County. High winds are forecast throughout the day today, with gusts exceeding 30 miles per hour and potentially accelerating down the west slope of South Fork Mountain, threatening communities to the west and north. The Ruth Valley and Mad River Valley are aligned to funnel the forecast winds and encourage fire spread in these areas. Residents are urged to comply with evacuation orders and to stay out of the area. Many roads are impassable due to fire and fallen trees. The fire remains extremely active; winds are carrying embers well beyond containment lines, and there is high potential for the fire to develop an active plume.

As fire activity increases with the winds and the heat of the day, large smoke columns are expected to form. Like thunderheads, columns build and then collapse. Collapsing columns are extremely dangerous, violently forcing winds outward, carrying fire and live embers far and wide. Extreme conditions are forecast into the evening; the Red Flag Warning is expected to end by 9pm.

Live embers were documented landing 8 miles ahead of the active fire front on Sunday. Spot fires ignited beyond control lines east of Forest Glen, north of State Route 36, and west of South Fork Mountain. The fires advanced to Ruth Lake and to the west side of the lake by afternoon. Crews are responding to the spot fires as conditions permit, working through the night. Firefighters continue to focus on firefighter and public safety, as well as point protection for structures.

New closures include all roads in Van Duzen, Mad River, Ruth, and Hettenshaw areas. Ruth Zenia Road is closed east of the US Forest Service Zenia Guard Station. The closure for State Route 36 now extends from the Humboldt County line on the west to the junction with Bowman Road on the east. New evacuation orders include Mad River, Lower Mad River Road, Zenia, and Kettenpom.

Smoke will likely move back into the region in the next day or two, calming fire behavior. Hot, dry weather will persist with prime conditions for continued fire growth. The winds are presently aiding containment work on the east flank. Crews continue to hold and improve the fireline, preparing for the return of seasonal winds from the southwest.

    WEST ZONE ** 116,759 acres and 65% contained***

    CAL FIRE’s unified team and the U.S. Forest Service are engaged in a coordinated and collaborative response to take suppressive action on the August Complex, which has been split into three zones to effectively provide a response for the communities at risk. Due to resource draw down throughout the state, CAL FIRE’s Incident Management Team requested the California National Guard to assist with fire suppression efforts and as a result of CAL FIRE’s request, 138 National Guard personnel are assigned to the incident. Additionally, resources from across the state of California as well as Montana, Idaho, Texas, Washington and New Jersey have been assigned to assist on the August Complex-West Zone. The August ComplexWest Zone has burned 116,759 acres, spans approximately 195 miles of fire line and is 65% contained with more than 1,600 firefighters battling the fire from the air and the ground. Over the last several days, Incident Commanders have been monitoring weather reports and the fire burning in the Yolla-Bolly Middle Eel Wilderness which is part of the August Complex – North Zone. In preparation for the potential impact that the forecasted red flag wind event could have on the fire in the Yolla-Bolly Middle Eel Wilderness, firefighters are working diligently from the air and the ground to strengthen and reinforce containment and control lines. Strong winds pushed the fire from the Yolla-Bolly Middle Eel Wilderness west, southwest towards control lines. Yesterday, the fire continued to be wind driven to the west and southwest prompting evacuation orders and warnings being expanded in Trinity, Humboldt and Mendocino Counties. Firefighters worked in extremely difficult terrain, performing structure defense and constructing both indirect and direct containment line in the Travis Ranch area. Overnight, the fire was extremely active north of Travis Ranch and east of Zenia where firefighters were faced with the fire making uphill terrain driven runs.
