On August 20th, the Bonner County Sheriff's Office updated the list of roads in the GO and the SET evacuation zones, in conjunction with the Sunset Fire.

These lists replaced the previously posted information, dated August 18th.

Roads in SET and roads in GO are listed on InciWeb at this link.

Water scoopers will continue to draw water from Lake Pend Oreille. Boaters: please stay out of the flight path of these planes to minimize disruptions to firefighting efforts.

CURRENT STATUS

Crews will work to hold and improve firelines along the western flank, working northward in the very steep terrain into Maiden Creek. Hotshot and type 2 hand crews will work from north to south from Pearl Creek to Maiden Creek. In the northern-most area of the fire, hotshot crews will camp near the fireline, or remain “spiked out,” and will stay on the fireline for several days. Mop-up operations to address areas of residual heat will continue on the southwestern flank. Aerial resources, including scoopers and helicopters, will continue to assist all firefighting efforts using water drops to support crews on the ground. Structure protection teams will finalize protection measures where needed south of Talache Road and Butler Creek. From the lakeshore, watercraft will insert crews into remote areas and will supply water to cool hotspots and active flames. An Unmanned Aircraft System (UAS) module with infrared (IR) capabilities will fly the fire area to look for hotspots and residual heat.

WEATHER AND FIRE BEHAVIOR

As temperatures increase to the mid to upper 80s and relative humidity drop to the low 20s, visible smoke is likely as larger fuels burn. North to northeast winds will be primarily on ridgetops and along the lakeshore. Winds elsewhere will be terrain driven at 5 to 10 mph. Hot and dry conditions are well established across the area with increasingly poor overnight humidity recovery.

Conditions for active fire behavior will be favorable earlier in the day, and smoke is likely to be visible from numerous locations. Active fire behavior with flanking, torching, and short-range spotting will increase, with short up-hill runs likely. Higher temperatures and lower relative humidity will result in increased potential for fire activity throughout the weekend.

EVACUATIONS, RESTRICTIONS, CLOSURES

The Incident Management Team worked in conjunction with the Bonner County Sheriff's Office to clarify the narrative descriptions of the evacuation zones for the Sunset Fire. Roads in SET and roads in GO are listed on InciWeb at this link.

There is an evacuation center at the Cocolalla Bible Camp to assist displaced residents. The Bonner County Fairgrounds are available to shelter evacuated livestock on a limited basis.

Area closures are in effect on the Idaho Panhandle National Forests. The area closure encompasses all National Forest Service Lands (NFSL) along the western shoreline of Lake Pend Oreille, from Camp Bay south to Three Sisters Horizontal Control Station. The closure extends west to Three Sisters Creek, then proceeds north to just south of National Forest Service Road (NFSR) 230. It then follows a stepped northeast path to Hickman Creek continuing east to the Forest Boundary and then heads north to Sagle Road. From Sagle Road, the boundary extends east back to Camp Bay.

More information on Idaho Panhandle National Forests area closures can be found at: https://www.fs.usda.gov/r01/idahopanhandle/alerts

A Temporary flight restriction (TFR) is in place that restricts all aircraft (including drones) from operating in the fire area without permission.

Most wildfires are caused by humans. Be part of the solution – learn how!

· Be aware of and follow all fire restrictions

· During closed burn season, before burning debris apply for a free burn permit – it’s the law

· Use campfires safely by staying clear of flammable debris and burning on mineral soil

· Maintain vehicles and OHVs properly – especially their tires - so you don’t spark a fire

· Secure trailer chains so they don’t drag and cause a fire

· Never park over dry grass because hot exhaust systems can start a fire
