RIM FIRE UPDATE: SEPTEMBER 2, 2013, 6:00 p.m.

Fire Update as of September 2, 2013, 6pm
Very active fire behavior was observed today on the south and east fire perimeters. Types of fire seen today included running ground fire, group tree torching, short crown runs, and spotting. In the north and west fire perimeter moderate rates of spread were observed both in advancing ground fire, and burnout operations. Good progress was made with burnout operations in the north and southeast sections. Reliance on aviation resources has been critical in an effort to slow the fires progress to allow suppression resources to establish control lines in areas where accessibility and safety can be achieved. The extremely dry fuels, high winds, and potential for long-range spotting remain a significant concern for the fire to advance beyond control lines.

·Note there is a website glitch. The estimated containment date for the Rim Fire is September 20, 2013.    <<< I sent Forest Service an email last night asking them if they had made a mistake by putting October 20th as the containment date for the past three days.  I guess they got my message.  :)

Basic Information

Incident Type	Wildfire
Cause	Under Investigation
Date of Origin	Saturday August 17th, 2013 approx. 03:15 PM
Location	Groveland Range District, Stanislaus NF
Incident Commander	Wilkins/lawshe

Current Situation

Total Personnel	4,359
Size	235,841 acres
Percent Contained	75%
Estimated Containment Date	Friday September 20th, 2013 approx. 12:00 AM
Fuels Involved	Brush, Oaks, and Pine
Fire Behavior	Active fire behavior continued into the late evening and moderated overnight as humidities recovered. Moderate rates of spread were observed both in advancing surface fire and backing fire. Heavy fuels still continue to experience complete combustion with high probability of ignition.
Significant Events	Good progress was made with burnout operations on the northwestern and southwestern edges of the fire. Mandatory evacuations continue south of HWY 120 towards Yosemite National Park north of the Old Yosemite Road. There is a closure of Tioga Road west of Yosemite Creek Picnic Area. A Stanislaus National Forest closure order is in effect for locations near and in advance of the fire. The evacuation advisory continues for areas east of Highway 108 from Ponderosa Hills north to Pinecrest. Several locations to the west side of Yosemite National Park have also had closures implemented as a result of the fire's spread. Access and difficult terrain remain concerns for crews and equipment.

Outlook

Planned Actions	Wildland Fire Modules will be assigned north of Cherry and Eleanor Lakes to monitor the fires advancement and contain spread in the rocky terrain where fingers of sparse fuels are present. Direct and indirect line construction with burnout as necessary south of Harden Lake in Yosemite National Park. Continued burnout operations planned in Yosemite National Park along Tioga Road as favorable conditions allow. Patrol and mopup in all areas except the southeastern edge.
Growth Potential	Extreme
Terrain Difficulty	Extreme
Remarks	Very active fire and extensive spotting continue to hamper suppression efforts and pose risks to firefighters. Type 1 helicopters are providing point protection and cooling areas where direct line construction can be achieved safely. Approximately 4,500 structures remain threatened in advance of the fire on both the east and west sides. Fire is expected to continue its eastward spread father into the west side of Yosemite National Park east of Aspen Valley. Due to inaccessible steep terrain and extreme fire behavior suppression efforts on active portions of the fire are being significantly challenged. Heavy reliance on aviation resources has been critical in an effort to slow the fire's progress to allow suppression resources to establish indirect control lines in areas where accessibility and safety can be achieved. The availability of heavy aircraft is pertinent to the success of suppression efforts. Continued warmer and drier weather is forecasted for the next several days, which will elevate control concerns and slow burnout progress. Remotely piloted aircraft is providing realtime visual and infrared intelligence on the fire. Transition to Incident Management Team Type 1 (Wilkins)to Incident Management Team Type 1 (McGowan) will occur on September 4, 2013.
