A crew of wildland firefighters surrounds a spot fire in the trees, using tools to dig line.

The Diamond Complex started July 16, 2024, and is located 18 miles southwest of Chemult, Oregon. The fires are burning in the steep, rugged terrain of the Umpqua National Forest. The United States Forest Service and Douglas County Sheriff are working in partnership with an Incident Management Team to manage these fires. Fire managers are employing a full-suppression firefighting strategy, while working to minimize risks to responders and the public. 

Latest updates

Latest operations video

Latest map

The Diamond Complex has been moderately active, with smoldering and creeping fire behavior, along with instances of active surface spread with isolated torching. Minimal perimeter growth has occurred as most of the activity has been inside the footprint as either green pockets continuing to consume or reburn in scorched needle cast. 

Predominant fuel type is mixed conifer timber, with litter, understory and considerable dead and down. Some areas of grass or shrub also exist, especially inside old fire footprints.  

4 of the 31 lightning caused fires within the Complex are not yet contained.

Significant Events

Minimal
Creeping
Smoldering
Isolated Torching

Narrative:
There was little fire activity on the Diamond Complex yesterday. Minor smoldering in heavy fuels is occurring, but no open flame or active fire spread has been observed. There is a chance for dry lightning this afternoon into early evening which could produce new starts.

Outlook
Planned Actions

Conduct patrol, holding, and mop-up operations as needed. Recon needs and develop plan for constructing fire break along road in DIV P to contain SW portion of Potter Fire. Patrol and mop up to the extent necessary on the fires edge. Repair all areas impacted by suppression efforts to the specifications outlined in the suppression repair plan. Maintain IA response Division to respond to any new starts in the IA area considering the potential for dry thunderstorms 9/01-02/2024.

Projected Incident Activity

12 hours: Minimal fire activity expected overnight unless dry lightning produces new starts.

24 hours: Minimal fire behavior expected as excellent RH recovery is forecast overnight with cooler than normal daytime temperatures. Daytime humidity is expected to be in the mid 30s. This combination of factors will minimize burn periods and discourage significant fire behavior. Smoldering and creeping possible. Outside chance that new ignitions could surface if lightning is experienced on the day prior.

48 hours: Minimal fire behavior expected, however, a warming and drying period is expected. Temperatures are forecast to return to normal (low 80s) with relative humidity values that could bottom out around 20%. Fire potential increasing, and fire activity likely increasing in the form of an uptick in smoldering and creeping.

72 hours: Warmer and dryer conditions remain. Winds remain relatively low, but no precipitation is expected. Fire danger continues to gradually increase, with increasing potential for low end fire activity. Low potential for escape, but minor smoldering and creeping or reburn is possible. No precipitation is expected. 

Anticipated after 72 hours: Fuels remain dry and fire potential continues to gradually increase. Conditions remain warm with low humidity. ERC values continue to increase daily. Threat to containment is not likely but is not zero chance either. Approaching weather system needs to be monitored for potential enhanced fire weather conditions.

Current Weather
Weather Concerns

CURRENT
Overnight humidity recoveries were much better this morning and stayed steady around 35-50% through midday. Skies started out sunny then clouds increased leading to showers and thunderstorms in the vicinity of the fires in the afternoon. Lightning strikes stayed just south and east of the complex through the afternoon hours and are forecast to end by sunset. The nearby storms brought much cooler temperatures with afternoon highs mainly in the 60s above 5000 feet and some 70s for the lower elevations. General winds were from the southwest 5-10 mph with gusts to 18-20 mph. No measurable rain has been observed across the complex.

PREDICTED
For Tuesday, humidity values will start out much higher at 70-90%. Skies will turn mostly sunny with afternoon highs seasonably cool in the 70s across most of the fire as humidity values lower to 30-35%. General winds will be from the northwest at 5-10 mph with gusts to 15 mph. For Wednesday through Friday we expect a noted warming and drying trend with highs back into the 80s with afternoon humidity values at 15-20% and poor nighttime recovery of 30-40%.
