Twenty-five Mile Fire Update
September 14, 2021

Fire Information Line: 509-761-9217 (Daily from 8 a.m. to 8 p.m.)

Size: 21,552 acres 
Total Personnel: 329 (6 crews, 15 engines, 3 helicopters, 15 water tenders, 3 heavy equipment)
Containment: 50% 
Location: 12 miles NW of Chelan, WA
Cause: Under investigation  

Pacific Northwest Team 3 will be transferring management of the Twenty-five Mile Fire to Southwest Team 3, at 7:00 am tomorrow.

Yesterday: Working northwest of Stormy Mountain along Devil’s Backbone, firefighters used aerial and hand ignition to further increase depth of the containment line west of the fire. Near East Point, in the North Fork of Thirty-five Mile Creek drainage, the fire burned actively in heavy fuels. This fire activity did not threaten containment lines but did produce smoke visible throughout the surrounding area. Heavy fuels will remain dry in the coming weeks and the fire will likely continue to burn though "islands" of green trees interior to the containment lines, producing visible smoke. Mop up continues in the Slide Peak area and elsewhere on the fire as crews continue checking for and extinguishing any hot spots. In areas where there has been no recent heat detected they continued to backhaul equipment so that it can be refurbished and made available for use where needed.

Today: Firefighters will continue working to bolster the containment line west of the fire ahead of a change in weather anticipated for later this week. While cooler, wetter, weather is expected for the weekend, there remains a need to ensure a secure containment line that will stop spread of the fire given the potential for warmer, drier, conditions to return in the coming weeks. Using both hand and aerial ignition, and as conditions allow, they will be working to complete remaining firing along the line southwest of the fire. Crews will also continue the progress made completing road repairs where needed to ensure safe access for fire personnel. 

Weather and Fire Behavior: Yesterday was mostly sunny with continued drying which allowed for active burning in some interior areas of the fire. Today will be similar, with potential for moderate fire behavior in unburned pockets of fuel. There will be a mid-week shift in the weather that will bring colder temperatures and significant precipitation by the end of the week. Cooler, wetter weather will slow fire behavior through the weekend although there remains the potential for a return to warmer drier conditions later in the month.

Evacuations: Effective at noon on September 13, all remaining evacuation notices related to the Twenty-Five Mile Fire were removed. For more information, contact Chelan County Emergency Management, or follow their Facebook page: https://www.facebook.com/CCSOEM.
