Fuels Involved

Timber (Litter and Understory)

Medium Logging Slash

Closed Timber Litter

Narrative:

There is a heavy dead and downed component in the fire area from winter damage from a few years ago. There is also commercial timber stands, reprod and harvested units in the fire area. 

Significant Events

Moderate

Backing

Creeping

Smoldering

Narrative: Warming temperatures, a few morning clouds that will clear out by noon and lowering humidity allowed for continued fire activity.  There are areas of smoldering, creeping and occasional short-lived flare-ups.  Stump holes and down large wood continued to produce smoke and limited flames.  Some small interior areas of unburned fuels continue to consume.

Planned Actions
  • Secure and hold direct line
  • Multiple Handheld IR cameras to assist with mop up
  • Improve, plumb, and begin mop-up on containment lines
  • Fall hazard trees to mitigate threats during mop up operations as needed
  • Provide initial attack within the TFR for new starts
  • Support suppression operations as requested within the delegation
  • Increase in repair operations
  • Back haul hose and hardware that is no longer needed
Projected Incident Activity

12 hours: As the cloud cover burns off in the afternoon humidity will decrease to around 50

24 hours: As the marine influence gradually recedes, resulting in clearing skies with daytime temperatures increasing slightly as the humidity drops allowing for continued fire activity. Overnight there is a potential for a thermal belt to develop and allow some fire activity to continue in the affected areas. The heavier fuels and burning stump holes will continue to produce smoke until consumed or extinguished resulting in areas of smoldering and creeping. During the peak burn period there may be some active backing and flanking in interior green islands or dirty burn areas, particularly those areas exposed to the sun.

48 hours: Developing moderate high pressure increasing warmer temperatures and lower humidity. This will allow for hot dry conditions increasing the availability of fuels and fire activity. The heavier fuels and burning stump holes will continue to produce smoke until consumed or extinguished. There could be areas of smoldering and creeping. During the peak burn period there may be some active backing and flanking in interior green islands or dirty burn areas.

72 hours: The high pressure will provide warmer temperatures and lower humidity.

Remarks
The Rattlesnake Ridge fire merged with Cougar Creek #1. Lighthouse #2 and Lighthouse #4 merged with Lighthouse #3. These have been marked as 100% contained, actual containment is reflected in Cougar #1 and Lighthouse #3
