Estimated Containment Date

Fuels Involved
The fire is primarily being carried by compacted short-needle conifer litter and dead/downed fuels under closed canopies.
Significant Events
Cloudy skies starting in the afternoon and lasting throughout the day limited evaporation rates in the fine fuels preventing any significant creeping fire to extend out from existing hot spots and heat sources. Despite stronger wind in the afternoon, fire behavior was limited to smoldering with rare short-duration flareups and no growth.
Planned Actions
Continue to mop-up and hold fire's edge near South 17 Mile Mountain. Mop-up along dozer line on ridge top west of West Fork of Hall Creek. Continue backhauling all hose lays and accountable property. Reinforce containment lines and mop-up east of drop point 156 to Stall Creek. Hold and secure west of DP 156, along Hall Creek. Continue backhauling all hose lays and accountable property. Mop-up direct handline north of Little White Mountain. Secure and mop-up within old spot south of Brush Mountain. Mop-up and secure constructed control lines north of Hall Creek Rd. Continue backhauling all hose lays and accountable property.
Projected Incident Activity
Smoldering will continue, but at a reduced efficiency overnight due to rapidly increasing humidity levels and high chances of fog setting up in valleys and drainages throughout the fire
area.
Weather Concerns
High clouds associated with an approaching upper-level disturbance moving across the region this afternoon. There was still ample sunshine which allowed temperatures to warm into the 60s/low 70s. Afternoon relative humidity was between 32 and 42 percent. Southerly winds prevailed in most locations between 5 and 10 mph with some gusts as high as 17 mph. An upper-level disturbance and cold front will move through the region Wednesday, resulting in more clouds, breezy west to northwest winds and slightly cooler temperatures. The disturbance will exit to the east Wednesday night leaving cooler and more humid air in place the rest of the week. Clouds and moisture will increase again on Friday as a strong low-pressure system moves in from the Pacific Ocean. Friday through Sunday will be mostly cloudy and cool with periods of rain. Thunderstorms are not expected but a wetting rainfall is likely.
