Bighorn Fire – June 18, 2020 Morning Update

Winds continue to challenge firefighters today

Acres: 31,208

Percent Containment: 40%

Start Date: June 5, 2020

Cause: Lightning

Origin Location: Santa Catalina Mountains

Personnel: 808

Injuries: 3 minor heat-related illnesses

Jurisdiction: Coronado National Forest, including portions of the Pusch Ridge Wilderness

Resources: 7 hotshot crews, 8 Type 2 hand crews, 2 Type 1 engines, 27 Type 3 engines, 1 Type 4 engines, 30 Type 6 engines, 3 Type 1 helicopters, 1 Type 2 helicopter, 4 Type 3 helicopters, 12 water tenders, 6 bulldozers

Yesterday, due to high winds, the fire made a large push to the north, growing by over 7,000 acres.

Today, fire managers anticipate the fire will move towards Charouleau Gap, depending on wind direction and temperatures. Fire crews and air support are in place preparing and widening fire lines for this expected spread of the fire. On Mt. Lemmon, the fire moved through Oracle Ridge and generated spot fires in Stratton Canyon. Expect highly visible smoke as those areas burn together today. Crews working overnight implemented controlled burns along the Catalina Highway corridor. Firing operations will continue today, if necessary, to protect values at risk.

Air operations including fixed-wing airtankers were up early this morning, dropping water and fire retardant to slow the fire’s spread. Winds will continue to be a factor today, but less so than yesterday. The fire burning in the Ventana Canyon area and along Samaniego Ridge will be monitored by air support today. Minimal downslope backing of the fire is anticipated in that area. Crews will tie together the two containment lines north of the fire perimeter to protect the communities of Oracle and San Manuel.

Ready, Set, GO! encourages Arizonans to get READY by preparing now for what threatens their community, be SET by maintaining awareness of significant danger and to GO, evacuate immediately when the danger is current.
