Estimated Containment DateSaturday September 01st, 2018 approx. 12:00 AM
Fuels Involved

Timber (Grass and Understory)

Chaparral (6 feet)

Tall Grass (2.5 feet)

Narrative:

The fire is now burning through portions of grass, timber litter, brush patches and dense timber stands. Fire activity is expected to increase in the afternoon hours after smoke clears the area. The fire growth has been moving north/northeast for the past several days. As westerly winds increase in the day, the fire will increase rate of spread (ROS) to the east as it enters east/west aligned drainages. Spots will ignite in light flashy fuels as the smoke burns off in the afternoon.

Probability of ignition is 75-80 during the day and 40% at night%.

Branch I:

Day: Fire activity will become active once smoke lifts and begins to move out of the area towards the later part of the afternoon. In DIV D, the fire will continue to back down towards the Eel River Road. Rolling material and spotting is still a high probability. The main fire near DIV F, DIV G, and DIV H will continue to move north/northeast following drainages. When the fire enters Cold Creek, the fire may split, going up towards DIV H following Eel Creek, and east towards DP 25 following the drainage.

Night: Fire will continue to be active in the evenings, but may increase in ROS in west/east facing drainages with downslope/downcanyon winds. Humidity recovery will be poor above 2000 ft. elevation, setting up favorable fuel moisture

conditions for firing.

Outlook

Planned Actions

Maintain and improve roads within Branch II to allow for safe and efficient movement of incident resources. Assess structure defense

needs and provide for structure defense throughout the Complex. Prepare and defend around structures to limit the impacts of fire spread around the structures within the firelines.

Hold existing containment lines, monitor interior islands, patrol, mop up and provide for suppression repair on the River Fire and the Southern portion of the Ranch Fire.

Continue preparing for and executing firing operations in Branches I, II as conditions allow. Hold existing containment lines, patrol and mop up provide for suppression repair on the River Fire and the Southern portion of the Ranch Fire

Branches I & II:

Construct and improve indirect line from Lake Pillsbury East/Northeast to Brushy Camp Ridge, continuing East/Southeast to tie in with line construction/improvement efforts in DIVs J/K.

Construct dozerline utilizing ridges and roads from Cabbage Patch NE to Branch I/V Break. Continue to improve and construct control lines from DP26 West to the Branch break at the 20N08 Road to limit fire spread South of Brushy Camp Ridge.

Complete and improve control line around Bonnie View and prep for firing operations around Bonnie View and the 18N06 Road.

Prep and improve the 18N06 Road from PD32 to St. Johns Peak for firing operations. Improve line from St. Johns Peak west to the M# Road at DP25. Continue to improve and construct indirect control lines from DP-26 west to the Branch break at the 20N08 Road to limit fire spread south of Brushy Camp Ridge. Construct and improve indirect control lines between DP25 and DP26.

Hold the 17N22 Road from Hornet Nest Ridge to DP32 as a control line. Improve the contingency line from Inian Springs Road to DIV J, and assist in firing operations.

Continue prep and defend around structures as necessary within Bonnie View, The Pocket and along the 18N02 Road to limit the impacts of fire spread around structures within control lines.

Prepare and improve line, assuring control line is as direct as possible. Scout and identify contingency lines & gather intelligence.

Remarks

Box 8a - Overall Complex Containment percentage is based on the combined incident completed line divided by the combined perimeter. It is not the combined containment percentage for each incident expressed as an average.

Currently, there are approximately 49 miles of uncontrolled fire edge, 0.2 miles of planned handline and 8.8 miles of planned dozerline to construct and improve on the Ranch Fire in Branches I & II. Additionally, over 20 miles of control line needs to be burned.

A National Guard UAV and a RC-26 platform and a USDA Forest Service FireWatch Cobra are assisting with intelligence gathering and providing extremely valuable perimeter data to the incident.

Should critical resources not be obtained expect containment date to be approximately 10/15/2018

Weather Concerns

***Hot with Critically Low Relative Humidity Through Monday***

WEATHER DISCUSSION: Warming and drying trend continues with near single digit afternoon RHs along with very poor recoveries. The general west and southwest wind will be very light during the afternoon hours while light east winds will be felt at night and early morning hours. Smoke will be more widespread and heavier while lifting is delayed until 1500. Forecast models are hinting at a marine influence on Wednesday.

Observed Weather Conditions from 0600-1800 (based on midslope):

Winds: Southwest 3-6 mph gust 10 mph.

Max Temp: 100

Min RH: 12%

Forecasted Weather for 1800-0600 (based on midslope):

Winds: East 5 mph.

Min Temp: 65

Max RH: 30%

Narrative:

An extremely dry air-mass remains over the region. Daytime minimum RH values will range from 8 to 13% while overnight RH humidity recoveries will also be very low. The hotter drier pattern will persist through Monday before a marine influence returns to the area on Tuesday, bringing slightly lower temps and higher RHs.
