Containment estimated at 5%

information released by US Forest Service

Yesterday there was increased activity seen along the southeast corner of the fire in the Slide Ridge area. Super scooper aircraft were used extensively to help reduce the spread to south and east. Engines and crews continued efforts around impacted communities, identifying hazards around structures and extinguishing hotspots. Crews were able to go direct along the fire line east of Twenty-Five Mile creek, significantly reducing the threat of the fire continuing to back down the slope towards the private property and homes along South Lakeshore Road. The weather conditions did produce gusty outflow winds and lightning was observed in the area. Crews again maintained an overnight shift, reinforcing structure protection operations in and around properties and homes.

Today, heavy equipment and crews will construct direct dozer and handline in the vicinity of Twenty-Five Mile State Park both to the south and west. Along the southern and western edges of the fire, crews evaluate opportunities to prepare for strategic firing operations along Slide Ridge and Devils Backbone. Firefighters will continue to improve and secure containment lines in the vicinity of Grouse Mountain. Structure protection efforts will continue along South Lakeshore Road.

A flash-flood watch continues over the area as storms are expected through Saturday afternoon. The storms will increase the relative humidity and dampen fire behavior but continued gusty outflow winds will be present across the fire area.Rotor and fixed-wing air resources will continue attack on the fire throughout the day. Aircraft may use local bodies of water, including Lake Chelan, to fill. Recreational boaters should be aware of aircraft takeoff and landings and keep a safe distance.
