September 13, 2017 - Fire activity was minimal yesterday due to increased relative humidity and precipitation from the last couple days. If conditions are favorable today fire crews will continue burn operations along Glacier Point road. Glacier Point road remains closed until further notice due to fire operations. Showers and thunderstorms are predicted this afternoon through Thursday with cooler temperatures and higher relative humidly through the end of the week.

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. Today crews will continue work along Glacier Point road on the north flank of the fire. The west and south flanks of the fire are contained, holding, and will continue to be monitored by aircraft and fire personnel. Areas of new smoke may be seen as the fire cleans up areas of unburned fuel interior. 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 area is very steep and rugged, with numerous natural barriers and minimal values at risk.
