Highlights: The Pima County Sheriff’s Department has adjusted the restrictions for the Catalina Highway. All Summerhaven, Soldier Camp, and Willow Canyon residents and employees (with proper documentation) will be allowed to return without an escort. More details are available at https://www.facebook.com/pimasheriff. Residents are reminded that it is illegal to enter the forest area closure.
Residents that have returned to Summerhaven may continue to see smoke during the day along with possible embers glowing at night. Firefighters continue to patrol around Summerhaven to ensure there is no active fire that could pose a threat to the residents in Summerhaven, Soldier Camp, and Willow Canyon. Successful firefighting efforts have resulted in increased containment up to 85%.
Weather: Mostly sunny followed by late morning and afternoon cloud buildups over the mountains. Minimum humidity levels are increasing to 15% across the lower elevations and 20 to 30% in the higher elevations. Temperatures will range from 103‑108 degrees in the valley. Hot temperatures are expected to increase into the weekend, with Sunday being the hottest day. An Excessive Heat Warning has been issued for Southeast Arizona starting Friday afternoon through Monday evening.
Yesterday’s Activity: Chipping operations began in Carter Canyon near Summerhaven to reduce brush and other vegetation material created during fireline construction. Firefighters “ground-truthed” several heat sources that were detected on the Wednesday night infrared flight. After a thorough investigation, firefighters determined that these hot spots were located safely within the containment lines and posed no threat.

Today’s Activity: Continue backhaul and removal of fire suppression materials. On the southwest corner of the Pusch Ridge Wilderness near Pima Canyon, crews will begin to disassemble a one-mile long hose lay of firehose, pumps, and water holding tanks. Rehabilitation of fireline will continue in the Marshall Gulch area. In addition to working on the suppression and repair projects, firefighters are also available to assist with any initial attack response needed for new fire starts in the area.
