News - 08/01/2021

Due to the multiple small fire starts over the last two days, which ignited in a remote location along the Upper Steamboat Creek Drainage, fire officials have established a complex. Newly named the Rough Patch Complex, these fires are located approximately 10 miles north of the Jack Fire. Approximately 22 new starts are associated with lightning storms that recently passed through the vicinity; they are burning in an area of limited road access and steep terrain. A new operational branch has been established to evaluate and manage the new complex, and a containment strategy has been formulated. Initial attack crews composed of firefighters from both the Jack Fire organization and the Umpqua National Forest are actively working to suppress the new starts. Local resources from the Douglas Fire Protection Association are also assisting with these efforts. Additional resources have arrived to manage these new developments, and more are forthcoming.

Outlook

Planned Actions

Transfer of command of the Jack Fire to NW Team 13 to occur tomorrow. For the portions of the Jack Fire north of Hwy 138, planned actions are to mop-up and patrol. South of Hwy 138 on the west side, SW side and a portion of the east flank are in mop-up and patrol. Where the fire jumped Calf Creek on the SE flank, continue to prep roads and constructed lines for defensive firing operations to contain the fire.

Projected Incident Activity

12 hours: Attempt to burnout of primary line to continue on southeast flank. SE flank in Calf Creek Drainage continues to spread southeast within existing primary line. Steep slopes and drought stricken fuels will continue to drive fire spread. Timber litter will spread into jackpots and lichens, encouraging torching and spotting.

24 hours: Fire spread and burnout within containment lines. Burnout of primary line to continue on southeast flank. SE flank in Calf Creek Drainage continues to spread southeast within existing primary line. Burn from 530 road to Twin Lakes and Twin Lakes north along handline continuing along the 4750 road. Islands left from patchy burn have potential to increase in activity with slope alignment, torching and spotting possible. Steep slopes and drought stricken fuels will continue to drive fire spread. Timber litter will spread into jackpots and lichens, encouraging torching and spotting.

48 hours: Cooler temperatures should keep fire behavior moderated. Jackpots and heavy fuels will continue to consume and propagate fire into lichen-laden timber canopy. Some isolated torching and spotting is possible.

72 hours: Fire behavior should moderate with cloudy and cooler conditions. Jackpots and heavy fuels will continue to consume and propagate fire into lichen-laden timber canopy. Some isolated torching and spotting is possible.

Anticipated after 72 hours: Same as 72 hr.

Remarks

The Fire currently is 100 percent on land managed by the Forest Service.
