Fire Update September 9th, 2017

September 09, 2017 Posted by: Yosemite Fire Information
There are multiple fires burning in Yosemite National Park's wilderness. Very little change in temperatures and humidities through the weekend. Slight chance for afternoon/early evening showers and thunderstorms for the next several days. A slight warming trend will begin Sunday.
 
Rattlesnake
Discovered: 9/7/17
Location: Hwy 120/Big Oak Flat Rd. at Foresta Rd.
Size: 15 ac.                 Cause: RV/ Vehicle fire   Containment: 100%       Fuels: Grass mixed shrubs
 Fire started due to an RV catching fire and spreading north into the vegetation. Fire is burning in the old Big Meadow Burn scar which helped limit its spread. Crews and aircraft were able to attack the fire and hold it to 15 aces. Crews will continue to mop up hot spots and secure lines today.
 
South Fork
Discovered: 8/13/17                           
Location: .75 miles east of the community of Wawona
Size: 6,640 acres        Cause: Unknown        Containment: 47%      Fuels: Mixed conifer and red fir
 
Fire remains quiet near the community of Wawona. The most activity yesterday was on the east flank burning into the wilderness through scattered pockets of dense fuel and the south flank backing into the South Fork of the Merced. Very little change in temperatures and humidities through the weekend. Slight chance for afternoon / early evening showers and thunderstorms for the next several days. A slight warming trend will begin Sunday.
 
The northern spot fire remains south of handline at Turner meadow, crews brought fire down to Chilnualna Creek to secure the spot fire with the main fire.  Patrols continue along portions of the fire closest to Wawona. There may be some burning well interior and visible smoke with increased winds due to the storms. Bucket work may be continued on the southern boundary of the fire. Both spot fires south of the South Fork of the Merced drainage were contained and secured with hose lays and handlines. Sections of the north flank and the entire east flank are continuing to burn in the wilderness, and will be monitored by aircraft due to steep and rugged terrain. As fire burns into the high country wilderness it will burn actively through pockets of dense vegetation but will then slow down as it progresses into sparse vegetation and natural granite barriers limiting smoke production. This high country wilderness area has minimal values at risk.
 
Empire
Discovered: 8/1/17     
Location1 mile east of Yosemite Ski and Snowboard Area and 3/4 mile south of Glacier Point Road
Size: 5,637 acres        Cause: Lightning         Containment: 55%      Fuels: Red fir             
 
Fire activity was active yesterday.  Glacier Point Road is closed. Crews are completing preparing the Glacier Point Road to implement their plan for strategic burning operations that may take place on the GP road to minimize high fire behavior along the road. Very little change in temperatures and humidities through the weekend. Slight chance for afternoon/early evening showers and thunderstorms for the next several days. A slight warming trend will begin Sunday.
 
Fire crews are implementing a perimeter control strategy for the north, west, and southern flanks of the fire to protect Bridalveil Campground, Yosemite Ski and Snowboard Area, Yosemite West subdivision, Wawona Road (Highway 41), and Glacier Point road. The north end of the fire is in monitor status, the west and south flanks of the fire are contained and holding. Areas of new smoke may be seen as the fire cleans up areas of unburned fuel interior.  Fire management personnel are implementing this strategy on three sides of the fire to minimize further smoke production in heavy fuels. The east flank is being allowed to move towards the Illilouette basin to continue to enhance forest resiliency in a fire adapted ecosystem
 
Yosemite National Park has managed fire in this wilderness area for decades. This high country wilderness area is very steep and rugged with numerous natural barriers and minimal values at risk.
