Jacobson Fire Morning Update 05-28-2025

Jacobson Fire
Publication Type: Announcement - 05/28/2025 - 08:14

Despite dry conditions, there was no growth on the Jacobson Fire last night. Night crews spent their shift running patrols around the fire area, monitoring fire activity. The infrared flight successfully mapped hot areas within the fire perimeter, and crews today will focus their attention on those remaining hot areas. 

Helicopters will assist ground crews by bringing in “blivets”, which are large, portable water containers used to store and deliver water to remote areas. Because the terrain on this fire is so steep, any water dropped from the air could cause burning debris to break free of the canopy or roll down hill and ignite a spot fire outside of the fire perimeter. Blivets are often used in situations like the Jacobson Fire, where there is no easy access to a water source and crews are working on difficult terrain. Ground crews will hike into the area and attach hoses to the delivered blivets to extinguish any heat along the fire perimeter.

Yesterday, the structure group put in fireline around the cabins at Turkey Flat and prepared to respond to any hazards to the recreation residences. The structure group will continue mapping the values at risk today to remain prepared for any incidents. 

Conditions are predicted to remain dry, with zero percent chance of precipitation. Winds are expected to be 4-14mph, with some gusts up to 20mph.
