SOUTH FORK FIRE:

Approximate Location

37.538 latitude, -119.598 longitude

Incident Overview

The north flank of the fire was the most active yesterday as it burned into heavy pockets of fuel. The south and west flanks of the fire are contained, some smoke will be visible as logs and brush burn in the interior. Crews will continue to patrol and monitor the flanks closest to the community of Wawona and Mariposa Grove. Crews are continuing containment strategies on the north-west edge of the fire and to keep fire south and south-east of Chilnualna Creek. The north and east flank of the fire is continuing to burn in the wilderness, and will be monitored by aircraft due to inaccessible and steep terrain. As fire continues into the high country it will hit some pockets of heavy vegetation with little fire history but slow down with natural granite barriers and sparse vegetation which will limit smoke production. This high country wilderness area has few high values at risk.

Basic Information

Current as of 8/29/2017, 2:47:32 PM Incident Type Wildfire Cause Unknown Date of Origin Sunday August 13th, 2017 approx. 02:30 AM Location .75 mile east of the community of Wawona Incident Commander Ty Crowe IC3 Incident Description Supression

Current Situation

Total Personnel 101 Size 5,191 Acres Percent of Perimeter Contained 44% Fuels Involved Timber (Litter and Understory) Brush (2 feet) Significant Events The following trail and area closures are in place until further notice: •The Swinging Bridge Trail on both the north and south sides of the South Fork of the Merced River. •The Chilnualna Falls Trail from Wawona Trailhead to the top of Chilnualna Falls. •The two mile connecting trail heading north from the top of Chilnualna Falls to the intersection of the Buena Vista Trail. •The Chilnualna Creek Trail from the top of Chilnualna Falls east to the intersection of the Buena Vista and Buck Camp trails (Just east of Johnson Lake). •Turner Meadow Trail •Turner Meadow intersection east to Buena Vista trail •Off-trail areas in the vicinity of the South Fork Fire Area, including the swimming holes north of Chilnualna Creek. • All climbing routes on and around Wawona Dome are closed.

Outlook

Planned Actions Mop up and suppression repair on the west flank of the fire. Monitor and check the fire spread near the S. fork of the Merced River on the SE side of the fire. Monitor fire spread on the north and east flanks. Remarks Crews continue to hot spot and cold trail the southeast portion (Div J) in an effort to halt the eastern spread of the fire. Weather is forecasted to get hotter and drier with expected increases in fire behavior until the high pressure system moves out and clouds and moisture move over fire area.The fire is located in the South Fork of the Merced River, with very steep and inaccessible terrain.

Current Weather

Weather Concerns A strong upper level ridge of high pressure centered over the Great Basin will continue to bring well above normal temperatures and light, terrain-driven winds to the fire through Tuesday with little diurnal change in humidity. A southwesterly flow aloft will become established over the fire by this afternoon and remain westerly through midweek as a weak upper level trough passes by to our north. Although a few thunderstorms could pop up over the higher elevations of Yosemite Tuesday and Wednesday, they will remain well east of the fire.

EMPIRE FIRE:

Approximate Location

37.644 latitude, -119.618 longitude

Due to a very dry air mass fire activity increased yesterday on the eastern flanks of the fire burning in heavy pockets of down and dead vegetation. The west and northwest flanks of the fire are contained and showed minimal activity. 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. Strategy for the east flank of the fire is to steer fire east deeper into the wilderness where there is sparse vegetation and natural granite barriers which will slow spread and limit smoke production. This high country wilderness area is very steep and rugged and has few high values at risk.

Fire management personnel is implementing this strategy on three sides of the fire to limit further smoke production in heavy fuels..

Today crews will be working to secure the Deer Camp trail from Alder Creek east for 3/4 of a mile. Glacier Point road is closed to the public due to fire fighter safety to conduct tree felling and vegetation clearance. Additional crews and engines are on order to support these operations.

Outlook

Planned Actions Continue to implement firing operations from the area of Turner Meadow Junction toward Deer Camp with the intention of tying the firing operation into Deer Camp and securing the southern flank of the fire to the western flank of the fire by end of shift 8/31/17. Continue to monitor and secure the northern flank of the fire above the Bridalveil Creek Campground. Continue to check up and secure the perimeter of the 50 acre spot fire to the east of Bridalveil Creek Campground. Projected Incident Activity 12 hours: Begin firing on the south flank from the area of Tuner Meadows toward Deer Camp 24 hours: Continue firing operation on the south flank from the area of Turner Meadows toward Deer Camp. 48 hours: Complete all firing operations by end of shift hold line and monitor fire. 72 hours: Continue to reevaluate fire behavior hold and monitor fire . Crews will be strategically positioned to monitor fire and allow the fire to naturally progress east further into the wilderness.

Current Weather

Weather Concerns A strong upper level high pressure center over the great basin will continue to bring above normal temperatures and light, terrain-driven winds to the district through the weekend with little diurnal change in humidity’s. A weak system moving through Northern California will slightly cooler temperatures by a few degrees on Wednesday. There is a slight chance of afternoon/early evening thunderstorms over the higher elevations of the southern Sierra Nevada through Thursday.
