South Fork Fire Update #10 August 22nd, 2017

August 22, 2017 Posted by: Yosemite Fire Information

Start date: 8/13/17 2:30 p.m. 
Size: 3,820 acres 
Cause: Unknown 
Fuels: Mixed conifer, oak and brush
Containment: 17%
Incident Personnel: 765

Burning operations above Wawona were successful yesterday as crews brought the fire down the containment line to the South Fork of the Merced. Today crews will finish burning the lower area along the river and continue to mop up on the west side. Firefighters have been inserted into the southeast portion of the fire to check the eastern spread and monitor the fireline north of the river.  
Mandatory evacuations will remain in place in Wawona for the area east of Highway 41 on Forest Dr. and Chilnualna Falls Rd. until further notice. 

A glide path to release resources has begun as containment increases. Strategic objectives remain the same: continue suppression efforts by utilizing air and ground resources to hold the western and southern flanks while monitoring the northern and eastern edges. Minimal Impact Suppression Tactics are being used in the Yosemite Wilderness to manage the area of the fire, using natural barriers such as rocks or streams, trails, and other minimal disturbance methods to contain the fire. 

Thunderstorm activity is expected again today and may cause erratic winds over the fire area. Storms are predicted to decrease throughout the week as system of higher pressure moves into the region. 

There are currently 765 personnel assigned to the fire: 22 hand crews, 7 helicopters, 20 engines.
