August Complex North Zone Fire Update
September 27, 2020
Incident Commander: Norm McDonald
Start Date: 08/17/2020 Location: Shasta-Trinity NF; Six Rivers NF; Mendocino NF
Cause: Lightning Fire Size (All Zones): 873,079acres
Containment: 43% Personnel (North Zone): 1,129
(Redding, CA) – Gusty winds, high temperatures, and low relative humidity triggered a Red Flag Warning for extreme fire weather for the August Complex through Monday. Blowing from the northeast, winds are pushing the fire back onto itself on the northeastern flank, limiting fire spread toward Forest Glen, Post Mountain/Trinity Pines, Wildwood, and communities north of the State Route 36 corridor.
Containment lines on the west and southwest sides of the fire will be tested by the winds, particularly in the areas of Ruth and Ruth Lake. Winds are forecast at 15 to 20 miles per hour, with gusts to 30, potentially accelerating down the slope of South Fork Mountain directly toward these communities. Peak winds are expected between 11am and 10pm, with a second peak after midnight. Please heed evacuation orders; residents are encouraged to stay out of the area for at least the next 48 hours. The fire weather is extreme for this area.
Air operations, heavy equipment, and hand crews have all worked in tandem to construct containment lines and implement structure protection measures in advance of the weather event. Recent strategic firing operations on the northeast and western flanks have been successful reducing fuels, intended to decrease the intensity of the fire as it approaches the containment lines. Pumps and hose systems are in place and tested for structure protection. Crews continue working to improve and widen firelines, with additional firing operations slated today for the State Road 36 corridor, aided by the wind direction. Aerial support is scheduled throughout the day, as conditions permit.
State Route 36 remains closed from the junction with State Route 3 on the east to South Fork Mountain Road at South Fork Mountain Summit on the west. Reopening is dependent on fire operations and fire behavior. County officials are on site directing traffic.
