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.
Shorter daytime burning period along with the increase of Relative Humidity and cooler seasonal temperatures have started to slowly affect the availability of fuels to openly burn.
Division A/D-Continue to secure and mop up handline and roaded containment lines.
Suppression/repair will continue on dozer and contingency lines throughout the division.
Division G- Hold, Mop up and patrol containment lines throughout division will occur by ground or air.
Repair and rehab of hand lines as needed will occur.
Division T/Y - Continue with mop-up and patrol. Crews are 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. Repair and rehab of hand lines as needed will occur.
Repair Group- Roads (gravel, grading, etc...) are being rehabbed to improve safety, reduce washout and improve traffic flow.
|Projected Incident Activity|
12 hours: Minimal fire behavior is expected as clearing skies continue. The 100 hr, 1000 hr fuels will continue to burn and consume where heat is present in the dead and down. Minimal spread is expected through the period.
24 hours: Surface fire comprised of backing, creeping, smoldering and isolated torching. Fire continue to burn moderately in unburned areas as clearing skies allow solar heating to dry the exposed dead/down fuels. Minimal fire growth expected.
A warming trend continued on Thursday as high pressure built over the region. Temperatures around 70 blanketed the valleys and the higher ridges showed temperatures nearing 60 with light wind.
Some residual dryness brought daytime humidity just a bit less than 30 percent Thursday. Warmer weather will continue into Friday peaking on Saturday before clouds and cooler temperatures come on Sunday.
