The Jack Fire, burning in the Umpqua National Forest, is showing a small gain in acreage, as of mid-day Wednesday.

An update from Northwest Incident Management Team 9 said the fire is at 13,907 acres and 15 percent contained. 781 people are working on the fire suppression effort.

The update said cooler temperatures and higher relative humidity the next few days will help resources hold the fire within the planned containment line. North of Highway 138E, crews will continue to hold, secure and mop-up along the 4760 Road moving towards Dog Mountain. Firefighters will burn vegetation away from containment lines in the northeastern corner of the fire perimeter as needed to hold the fire within the planned containment area. In the Dry Creek area, crews continue mop-up around the structures.

The update said south of Highway 138E, on the western perimeter of the incident, the fire continues to move south along the 4714 Road. Crews will continue to hold the fire east of the road, burning out vegetation as needed to strengthen the line. Crews are utilizing trails, roads and hand lines to hold the fire within the planned containment lines on the southern-most edge of the fire. Firefighters are working to hold established containment lines while preparing lines to the south.

Four Type 1 aircraft and two Type 3 aircraft continue to support firefighters on the ground.

All evacuation levels and locations remain the same at the Jack Fire. Highway 138E remains closed from Steamboat Creek to milepost 55.
