The Jack Fire, burning on the Umpqua National Forest, is 55 percent contained, and has gained nearly 1,000 acres in the last day.

An update from the Northwest Incident Management Team 9 said the fire is at 18,993 acres. 741 people are working on the fire.

North of Highway 138E, firefighters continue mop-up, securing and deepening primary line. Fallers are removing snags, and at-risk trees to make roads safe to travel. Crews continue to monitor fire behavior along the North Umpqua River.

South of Highway 138E, crews continue mop-up and brushing operations. Heavy equipment crews will prepare line, creating potential control lines along shaded fuel breaks. Firefighters plan to continue burning vegetation to achieve depth along control lines to secure line on the south and southwest flanks. On the southeast and east flank, crews will utilize heavy equipment and fallers to clear and brush out roads used as control lines. Crews will continue to scout for alternative line locations to tie fire to Calf Creek.

The update said on Monday hose layout was pulled from around structures in the Dry Creek area. Crews continue to mop-up and patrol around structures in that area, and around Horseshoe Bend Campground.

Air support includes two Heavy Type 1 helicopters with buckets and one Heavy Duty Type 1 helicopter with a tank along with one light Type 3 helicopter.

The Northwest Incident Management Team 9 is working side-by-side with the Northwest 10 Team to ensure a smooth transfer of command.  NW 10 will take the lead on the fire on Wednesday.
