Current Situation

Total Personnel:
38
Size (Acres):
1,233
Containment:
30%
Estimated Containment Date:
Friday, October 1, 2021 12:00 AM PDT
Fuels Involved:
Timber
Brush
Significant Events:
Fire behavior primarily includes isolated pockets of smoldering and creeping. Overnight trace precipitation (less than .05") has slowed drying and delayed the return to conditions that will sustain
fire spread. Heavy fuels (log ends, concentrations, stump holes) continue to consume in-place due to drying effects of Summer drying.

Planned Outlook

Planned Actions:
Monitor fire activity within indirect containment features. Take appropriate holding actions as warranted by fire
behavior. Transition to local
unit.
Projected Incident Activity:
12 hours:
Overnight relative humidity recovery will limit fire spread. Heavy fuels (log ends, stump holes, concentrations) will continue to hold heat and consume in-place due to seasonal dryness. Smoke production continues and can be expected to settle into valleys.
24 hours:
Seasonal warm and dry conditions will return potential for limited fire spread. As surface drying
occurs sheltered fuels are also drying but at a slower rate. Smoldering, creeping, and limited surface fire spread is anticipated. Several heat sources on northern portion of the fire will
continue backing through heavy timber fuels. Isolated interior heavy fuels (log ends, stump holes, concentrations) will continue to hold heat and consume in-place due to seasonal dryness. Smoke production continues from fire activity in several scattered heat sources.
48 hours:
Seasonal warm and dry conditions will return potential for limited fire spread. As surface drying
occurs sheltered fuels are also drying but at a slower rate. Smoldering, creeping, and limited surface fire spread is anticipated. Several heat sources on northern portion of the fire will
continue backing through heavy timber fuels. Isolated interior heavy fuels (log ends, stump holes, concentrations) will continue to hold heat and consume in-place due to seasonal dryness. Smoke production continues from fire activity in several scattered heat sources.
72 hours:
Seasonal warm and dry conditions will return potential for limited fire spread. As surface drying
occurs sheltered fuels are also drying but at a slower rate. Smoldering, creeping, and limited surface fire spread is anticipated. Several heat sources on northern portion of the fire will
continue backing through heavy timber fuels. Isolated interior heavy fuels (log ends, stump holes, and concentrations) will continue to hold heat and consume in-place due to seasonal dryness. Smoke production continues from fire activity in several scattered heat sources.

Weather Synopsis

Weather Concerns:
Cumulus clouds developed during the day over Bulldog Mountain and Mack Mountain but with less cloud coverage compared to Tuesday. Temperatures were a little warmer and the humidity was a
little lower as a result. Afternoon temperatures ranged from 55 to 65 degrees, and the humidity ranged from 38 to 48 percent. Winds were light from the north-northwest at 3 to 8 mph mph along the ridgetops.
The weather pattern changes little through Friday, therefore the temperatures, humidity, and the wind forecast will be similar to
today. An increasing southwest flow will bring warmer temperatures and lower humidity this weekend through early next week. High pressure will also strengthen for dry and stable conditions.
