The North Fork Lost Horse Fire, ignited by lightning on July 24, grew to 40 acres as of July 25, with fire activity increasing due to extreme heat, low humidity, and winds over 40 mph. Firefighters used three helicopters for bucket drops on July 25.
The fire is in steep, rocky terrain on an 8,000-foot slope in the Bitterroot National Forest. A Type 3 incident management team has been deployed, with four engines, two water tenders, and a suppression module on scene. Weather will be 82-87 degrees with 8-12 mph westerly winds today.
Smoke from the fire has filtered into the Bitterroot Valley from Oregon and regional fires, according to the report.
