Empire Fire Update #37 September 12th, 2017

September 12, 2017 Posted by: Yosemite Fire Information

Location: 1 mile east of Yosemite Ski and Snowboard Area and 3/4 mile south of Glacier Point Road
Discovery Date: July 31st, 2017
Incident Personnel: 43
Size: 6,000 acres
Helicopters: 1
Containment: 55%
Cause: Lightning

Fire activity was minimal yesterday due to increased cloud cover and precipitation. Fire crews implemented a strategic burning operation along Glacier Point road from Mono Meadow Trailhead towards Horizon Ski trail. Glacier Point Road remains closed until further notice due to fire operations. Showers and thunderstorms are predicted this afternoon which may bring moderate rain and frequent lightning.

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.

The following trail and area closures are in place until further notice:

• Glacier Point Road
• Bridalveil Campground
• Ostrander Trail
• Bridalveil Trail
• Alder Creek Trail
• Mono Meadow Trail
• Turner Meadow Trail

Yesterday smoke was good to moderate throughout the Yosemite area for most of the day. Dispersion remains poor today and tomorrow, however most areas are likely to stay in the good to moderate range unless there is new fire activity. The fire area received substantial wetting rain yesterday and activity should be minimal under continued high humidity and light winds. 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.
