River Complex Fire Update Monday September 27, 2021

Etna, CA- Air and ground resources held the fire during the last several days.  Today’s fire behavior will be dependent on the arrival of the cold front which is forecasted to bring light precipitation. Cooler conditions and higher humidity combined with great overnight recovery will support continued direct line construction across the portions of the perimeter that can be accessed.  Crews will continue to pay close attention to the flank south of Minnehaha as it backs down to the dry creek bed before the rain arrives. 

Yesterday, crews were able to complete the containment line around the Tangle Blue spot fire.  Crews will continue to keep the Cronan Fire within existing control lines and prevent the Haypress Fire from spreading to private property and surrounding communities.

Plan, Prepare, and Stay Aware: The geography, weather patterns and number of Wildland Urban Interface communities in California make it a state particularly threatened by devastating wildfire. As catastrophic wildfires continue to increase each year in California, make sure to protect yourself and your family – plan, prepare and stay aware. Property owners and residents in areas most at risk are encouraged to take the steps in CAL FIRE “Ready, Set, Go!” to be ready for wildfire.

Size198,248 Acres
Percent of Perimeter Contained67%
Estimated Containment DateMonday November 01st, 2021 approx. 07:00 AM
Fuels Involved

Live and dead fuels are critically dry due to severe drought. 1000-hour dead fuel moisture is well below 10% and live fuels are below 100%. Overstory vegetation is mixed conifer and surface fuels include shrubs and grass.

Significant Events

Aircraft support assisted ground crews to keep fire intensity moderated on the several portions of the fire holding the most

potential. Although single tree torching was observed, most fire behavior can best be described as a backing and flanking fire. Roll-out continued to pose issues on the steep slopes above Minnehaha Creek and Little Mill Creek.


Planned Actions

Keep the fire within current containment lines around the community of Callahan. Continue to implement new contingency


Continue direct tactics as resources allocation and fire activity allows.

Control lines are in on Div Q are secure and we have initiated backhaul of excess hose and property.

We continue to have rollout day and night in Divs M and N. Interior pockets and fuels adjacent to the line continue to consume creating additional control issues and challenges for firefighters. Continued direct line construction in Divs M. We are quickly returning to the critical fuels conditions that are conducive to a longer burn period and increased threats to the adjacent


We continue to add resources to Div N to cold trail and secure the 14 miles of open line in Div N. Crews continue to spike for another 4-6 days.

We have 3 wildfire modules and 1 Type 2IA crew continuing to work on the Tangle Blue Spot fire.

Requested crews are needed to support the crew insertion mentioned above. We are supporting the spiked crews via longline. Currently, we anticipate 4-6 days worth of work for with what is available. We will continue to build contingency lines in Div N on private timber stands between Trinity Center and the Hwy-3 corridor.

Offensive tactics will

continue until weather conditions force extraction of the spiked resources.

Projected Incident Activity

12 hours: Breezy conditions will persist overnight in the upper elevations, but a settling inversion and slightly higher

humidity should keep overnight fire activity isolated to the upper portions of the fire most exposed to the winds.

24 hours: The timing of the approaching cold front will determine the fire activity today. Increased cloud cover and higher humidity should moderate activity until precipitation begins in the afternoon. Although the forecasted amounts of rain are light (.10") the cooler conditions and good overnight recovery will allow crews to continue their direct attack efforts.

48 hours:

The favorable weather conditions will continue for the operational period minimizing fire behavior across the fire. This will allow crews to continue to be successful in their direct line construction.

72 hours: There will be a drying trend behind the cold front but the excellent overnight recoveries will moderate fire activity across the remaining uncontrolled portions of the fire. Having the appropriate resources (Type-1 Handcrews) to

take advantage of this opportunity will allow resources to be successful with their direct suppression efforts and

alleviate concerns for future significant perimeter growth.

Current Weather

Weather Concerns

Dry conditions continued Sunday with temperatures running near to slightly

above normal. Relative humidity dropped into the teens in many areas. Ridgetop winds from the southwest gusted 20 to 25 mph in the afternoon with valley winds in some areas gusting 10 to 15 mph. Gusty winds will continue Sunday night, mainly along ridgetops, ahead of a cold front. Humidity will increase

Sunday night ahead of the front, which will cross the area Monday afternoon. The front will be accompanied by increasing humidity, light rain and gusty

southwest winds. Temperatures will drop below normal Tuesday and Wednesday before returning near normal for the end of the week. Overnight humidity recovery will be excellent through the middle of the week.
