Closed Timber Litter

Significant Events

The potential burning in the Petes Lake fire will slowly start back up as the moisture starts to decline, the potential for some moderate burning may occur along edges of the fire that still have some heat.

Observed Fire Behavior:

Minimal

Creeping

Smoldering

 

Planned Outlook

Planned Actions
Continue prep along the Cascade Lakes Highway to construct a shaded fuel break for potential containment lines. Continue to use aircraft and crews as needed in the fire area. 

 
Projected Incident Activity

12 hours: Continued active fire behavior with single and group tree torching, flanking, backing with

24 hours: Continued red flag conditions with higher temps, lower RH, and NE winds with gusts to 25 mph. Expect active fire spread overnight. Spread through spotting, backing, uphill runs, flanking,

48 hours: Potential for the lowest RH values and ENE winds to continue into Thursday. Increased

72 hours: Potential for the lowest RH values and ENE winds going into Thursday. Increased ridgetop

72 hours: Following the warm, dry, and windy pattern. Conditions are expected to return to near normal values but with no precipitation anticipated. Increased perimeter heat will lead to additional growth along ridges or exposed areas.

12 hours: Fire behavior is expected to be minimal. Creeping and smoldering in duff with isolated jackpots of concentrated heavy dead and downed fuels. No perimeter growth is anticipated.

24 hours: Seasonable warm and dry weather will continue and allow for interior fuels to continue to consume. Fire behavior will be creeping and smoldering in surface fuels while consuming jackpots of concentrated heavy dead and downed fuels. No perimeter growth anticipated.

48 hours: Continued warm and dry weather, fire behavior potential will be limited to areas of available fuels interior to established control features. No perimeter growth anticipated.

72 hours: Continued warm and dry weather, fire behavior potential will be limited to areas of available fuels interior to established control features. No perimeter growth is anticipated.

72 hours: ERC values for the area are forecast to rise near the 90th percentile by Friday. No perimeter growth growth is anticipated.

Remarks
Because the majority of our current efforts will be focused in areas that are not directly on the fireline, success on this fire will be measured by meeting the primary objectives rather than containment percentage.  
Shade Fuel Break: target 200 foot depth from road edge.
Planned construction length - 9.7 miles
