The Stanislaus National Forest Closure Order for the Rim Fire area has been expanded along the northern end of the fire's edge. Please see the closure announcement and closure area map for more details. Note that the Dodge Ridge Ski Area is still open.

There are currently no mandatory evacuations or evacuation advisories for Mariposa County. An evacuation advisory remains in effect for Ponderosa Hills and areas east, along the south side of Highway 108 up to Pinecrest. Highway 120 at the Yosemite National Park boundary west to Buck Meadows has been evacuated. 

Smoke from the Rim Fire has settled into Yosemite Valley, Wawona, Foresta and other areas, causing air quality impacts. This will persist for the next few days, particularly in the morning hours.

Fire Update as of September 1, 2013, 6pm
Line construction combined with burning operations continued overnight where safe conditions and accessibility allowed on the east and southeast flanks of the fire. There has been good progress made on the spot fires occurring near Pilot Peak and along the southern perimeter. Fire activity continues to be active in the south and southeast with moderate rates of spread and torching. Today winds will be coming from the south southwest with up to 20mph gusts. Fire activity has been slow and moderate in the north end of the fire. Today’s fire weather is extreme. Very active fire and extensive spotting continues to hamper suppression efforts and pose risks to firefighters. Air resources continue to be utilized in assistance with spot fires, slowing fire advancement, and control lines in advance of the fire spread.

Estimated Containment DateSunday September 20th, 2013 approx. 12:00 AM
Fuels InvolvedBrush, Oaks, and Pine
Fire BehaviorActive fire behavior overnight on the fire's south and east sides with moderate rates of spread and torching. Moderate rates of spread were observed both in advancing surface fire and backing fire on the northern and western fire perimeters. Heavy fuels still continue to experience complete combustion with high probability of combustion.
Significant EventsGood progress was made with burnout operations on the northwestern edge 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 ActionsDirect and indirect line construction with burnout as necessary south of Harden Lake in Yosemite National Park. There will also continued direct and indirect line construction accompanied by burnout oeprations where accessibility and safety allow along the eastern edge of the fire. Burnout operations will continue in the Hull Creek Drainage. There will be reinforcement of contingency lines in advance of the communities of Tuolumne City, Twain Harte, and Long Barn. Mopup and patrol will happen along the southwest edge of the fire. Construction and improvement of contingency lines along Dodge Ridge will continue. The burnout operation on the eastern edge of the fire in Yosemite National Park along the Big Oak Road and Tioga Road will continue as favorable conditions allow. There will also be continued burnout operations near Clavey Meadow. Mop-up and patrol on the central western edge of the fire.
Growth PotentialExtreme
Terrain DifficultyExtreme
RemarksVery active fire and extensive spotting continue to hamper suppression efforts and pose risks to firefighters. A signficant utilization and reliance upon aerial resources with heavy air tankers including the VLAT DC-10 and MAFFS is occurring with reinforcement of control lines in advance of the fire's spread, control of spot fires, and slowing the fire's advancement through terrain inaccessible to ground resources to allow time for indirect line construction to be completed. Type 1 helicopters are providing point protection and cooling areas where direct line construction can be achieved safely. The extremely dry fuels, highs winds and potential remain signficant concerns for the fire to advance beyond retardant lines. 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. Several residents remain under mandatory evacuation in the Scotts Ridge area south of HWY 120.
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. Continued unified command with CAL FIRE.
