Size: 7,580 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. There was an increase in acreage due to more accurate mapping. Thunderstorms are predicted this afternoon with slightly cooler temperatures and higher relative humidities, producing gusty and erratic winds.
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.
Location: 1 mile east of Yosemite Ski and Snowboard Area and 3/4 mile south of Glacier Point Road
Size: 5,100 acres Cause: Lightning Containment: 55% Fuels: Red fir
Fire activity was minimal yesterday. Acreage has increased due to more accurate mapping. Glacier Point Road is scheduled to reopen on Tuesday, September 5, 2017, if favorable conditioned continue. Signage and traffic control will be in place to mitigate smoke and other hazards on the road; there is a potential for implementing temporary road closures or single lane convoys from Bridalveil Camp Ground to Mono Meadow trailhead depending. Weather forecast for today predicts possible thunderstorms over the wildfire location, which could bring gusty and erratic winds. A cooling trend with increased relative humidity is expected over the next 24 to 48 hours.
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, 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.

Smoke dispersion will improve today, with more direct southerly winds. These southerly winds will bring smoke from the Railroad Fire directly into Yosemite National Park. Air quality will remain poor close to the fire especially in valleys and drainages north of the fire. Fire Managers are working with the local Air Quality Districts and will be monitoring smoke impacts to the park and local communities. Community members who are sensitive to smoke may want to close their windows and doors, limit outdoor activity, and monitor the air quality forecast linked below for changes to the forecasted patterns.
