There will be a community meeting Saturday at 6:00 p.m. at the Grade School Gym located at 392 Main Street, Fossil, Ore. The meeting will also be available on the Lone Rock Fire Facebook page. The community is encouraged to attend and receive firsthand updates from the unified command of the Northwest (NW) Team 2 and the Oregon State Fire Marshal (OSFM) Red Team.

Condon, Oregon — The Lone Rock Fire is being managed under a full suppression strategy by the unified command of the Northwest (NW) Team 2 and Oregon State Fire Marshal (OSFM) Red Team.

Yesterday’s Activities: On Friday, extreme fire behavior began earlier in the day compared to recent days. This extended the duration of extreme fire behavior and the hot, dry conditions led to fire spread to the south. OSFM resources, including several enhanced taskforces, provided structure protection to dwellings south of Forest Road 25 to Spray, Ore. An east-northeast wind component pushed the fires’ southern perimeter south towards Spray, Ore. Throughout the day, firefighting conditions were extremely hazardous, forcing firefighters to temporarily disengage for their safety. Three more taskforces arrived yesterday bringing the total count of structural taskforces to 11. Firefighters were able to contain multiple areas that slopped over containment features along Forest Service Road 21. OSFM task forces worked in Lonerock, Ore. to continue mop-up operations and hold the progress that was made through the week. The northern area of the fire continues to hold and firefighters remain on the scene to ensure the fire’s perimeter remains secure.

Today’s Activities: Fire behavior is elevated to critical levels with the Red Flag Warning with fire conditions near or above record highs. The dry fuels and forecasted weather are favorable for extreme fire behavior which will be resistant to control. Firefighters are focused on fundamental firefighting practices which include prioritizing safety, having backup plans, and using effective tactics to ensure a high probability of success. This pattern of extreme fire conditions is anticipated to amplify over the weekend. Thus, continued extreme fire behavior and additional fire growth is expected. Operations Section Chief Sonny Caldwell stated, “we are experiencing fire behavior that is exceeding all of our current modeling data.”  However, firefighters and the entire incident management team remain agile and focused on protecting human life and minimizing fire spread with strategy and tactics likely to ensure a high probability of success. Today, OSFM taskforces will have a significant presence in and around the town of Spray, Ore. They will also integrate with their wildland partners to work the southwest side of the fire and southeast side of the fire from Winlock Road to the Morrow County OHV Park. Two additional taskforces will be sent to the Boneyard Fire to provide day and night coverage to the Monument community as an additional incident management team is expected to arrive on that fire later today.

Three helicopters are assigned to this incident and will concentrate on dropping water over the southern area to support and enhance the efforts of the firefighters on the ground.

Weather: A Red Flag Warning for hot, dry, and unstable conditions is in place from 11:00 a.m. Saturday through 11:00 p.m. Sunday with a dry cold front passage Sunday evening.

An offshore flow under a ridge of high pressure will result in breezy east to northeast winds over the weekend. It will also be hot, dry, and unstable with critical fire weather conditions expected through Sunday evening. A cold front late Sunday afternoon into Sunday evening will bring the potential for virga showers and a small threat (up to 10% chance) for isolated thunderstorms.  Any showers or thunderstorms that develop will bring a threat for gusty and erratic winds Sunday evening into Monday. Cooler temperatures are expected next week with a return of northwest winds.

Flight Restrictions: A Temporary Flight Restriction (TFR) is in place above the Lone Rock Fire area. If you fly, we can’t. Unauthorized drone flights (UAS) pose serious risks to firefighter and public safety and the effectiveness of wildfire suppression operations. Aerial firefighting is suspended when unauthorized UAS are in the area, allowing wildfires to grow larger.
