Jack Fire Wildfire
News – 7/29/2021

Fire Information: At this time, the Jack Fire has burned 22,491 acres and is 61 percent contained. The fire is burning in steep, rugged terrain that is difficult to access, and it continues to be a challenge for fire operations. Yesterday’s relative humidity was too high for crews to conduct their intended firefighting operations, but allowed time for firefighters to prepare for these operations when weather conditions become more favorable.

Current fire behavior is most active south of Hwy 138 in the east, southeast, and south flank of the fire. Crews there are preparing for firing operations as conditions allow, including at the 4770 road, along the 520 road to Twin Lakes, and near Calf Creek. If burn operations occur, please be aware smoke may be visible to the public. Firefighters are successfully holding the control lines north of Hwy 138, where mop-up, patrol, and monitoring activities continue on the northeast, north, and west perimeters of the fire. Last night’s infrared scan indicated a spot fire starting near the west flank; crews will work to contain this start.

Note that a RED FLAG WARNING has been issued for today (Thursday) through Friday due to the extreme heat and low relative humidity with a 30 percent chance for dry thunderstorms over the fire. Concern is for firefighter safety, new fire starts, erratic winds near thunder cells, and potential for unpredictable fire behavior.

Structures: Firefighter presence continues within Dry Creek patrolling and monitoring the area.

Aviation: Air support consists of two heavy Type I helicopters with buckets, one heavy Type I helicopter with a tank, and one light Type III. On Tuesday, aviation resources dropped 4,320 gallons of water on the Jack Fire and spent 2.6 hours in the air. A Temporary Flight Restriction (TFR) has been established over the Jack Fire to protect aircraft that are involved in the firefighting operation. All unauthorized aircraft, including drones, are prohibited from flying over the fire. Please do not use drones or any other restricted aircraft listed near the fire as it is a federal crime.

 Safety: Our primary mission continues to be managing wildfires, taking care of the community, and meeting the objectives identified by the agency administrators. Be advised to watch out for heat-related illness due to excessive heat conditions through today (Thursday) and Friday. Additionally, protecting the community and our firefighters from contagious diseases, such as COVID-19, is also a priority. COVID precautions and procedures have been implemented to ensure the safety and health of all fire personnel and the community we serve. Our staff will continually be monitored to ensure protection measures are effective and in alignment with the primary objectives of protection from wildfire.

Safety on Hwy 138: At this time, Hwy 138 remains open. Be aware there are possible speed limit changes and increased traffic due to fire personnel. Please follow the posted speed limit for your safety and the safety of firefighters.

Closures: The Umpqua National Forest currently has closed certain areas within the national forest for the safety of the public. The full closure order and map can be viewed at and on the Jack Fire Facebook page.

Evacuations: As designated by the Douglas County Sheriff's Office, the current evacuation levels remain the same. A current evacuation map can be found at .

Weather: Meteorologists assigned to the fire issued a Red Flag Warning over the fire area due to the potential for dry lightning and gusty winds that are predicted to continue through Friday. Subsequently, weather conditions will trend hotter and drier for both Thursday and Friday. Thursday’s temperature will be near 100°F in the lower elevations, with relative humidity at 17 to 25 percent. There is a 30 percent chance of scattered dry thunderstorms and erratic wind gusts. Outside of the storms, afternoon winds will be mainly terrain-driven out of the northwest to north at 6 to 8 mph and gusts up to 15 mph. Weather conditions are expected to stabilize beginning on Saturday, with lower temperatures and cloud cover predicted for next week.
