Reminder about Drones: If you fly, we can’t. All aerial suppression efforts are grounded when drones are detected within the restricted flight area of the fire.

Yesterday: In the northeast section of the fire, where a flare up occurred within the containment lines, firefighters concentrated efforts on wetting and mopping up hot areas. A helicopter made bucket drops while firefighting crews and four engines installed hose lay and mopped up any warm areas.

Estimated Containment Date:

Fuels Involved:
Short grass, brush, and timber. Pot Peak burn footprint with shrubs and varying amounts of standing and fallen snags. Fire spread is driven by the density and dryness of the heavy fuels, leading to fingering and patchy burn patterns. Regeneration and shrubs may or may not, depending on moisture, contribute to the continuity of the fuel bed, allowing fire to spread with wind or slope.
Significant Events:
A shorter burn period, an increase in cloud cover and higher relative humidity has affected the availability of fuels as well as the fire intensity.

Planned Outlook

Planned Actions:
Division A/D-Continue to secure and mop up handline and roaded containment lines. Chipping
throughout the division.
Division G- Hold, Mop up and patrol containment lines throughout division will occur by ground or air. Division T/Y - Continue with mop-up and patrol. Crews are chipping and are identifying and implementing rehab and repair of firelines (specifically dozer lines) using heavy equipment.
Division N-Monitor main fire, specifically fire below East Point and thirty-five mile creek. Roads Group-Roads (gravel) are being rehabbed to improve safety and traffic flow.


Projected Incident Activity:
12 hours: Fire behavior continues to be reduced as the cloud cover helps to maintain the high relative humidity which is keeping the 1hr fuels at the moisture of extinction and the fuels won't sustain burning. Minimal spread is expected through the period.

24 hours: Surface fire comprised of backing, creeping, smoldering and isolated torching. Fire could burn active in unburned areas after several days of drying in dead/down fuels. The rain event late in the shift will not be as strong as first forecasted . Minimal fire growth expected.

Weather Synopsis

Weather Concerns:
35. Weather Concerns (synopsis of current and predicted weather; discuss related factors that may cause concern):

Clouds and light rain moved in on Friday bringing a cooler day with light wind. The moisture raised humidity levels into the afternoon hours. Precipitation will likely increase Friday night into Saturday morning as a moist, cold front moves through. Showers along with unseasonably cold temperatures and higher humidity will continue Saturday afternoon into Sunday. Look for max temperatures only in the upper 30s and 40s in the higher elevations and middle 50s to near 60 along the mid-slopes and near Lake Chelan. Some drying and warming is anticipated starting next week.
