The Fresnal Fire was discovered burning towards the international border in Mexico on July 7th. The fire’s ignition source at the present time is unknown. It quickly spread to approximately 500 acres and burned northeastward across the international border onto Coronado National Forest lands. By evening, Mexican “Bomberos” had engaged the fire south of the border. Coronado National Forest fire crews also responded to the fire as it moved into the United States.
This morning crews north of the border coordinated with Mexican crews and jointly conducted burn outs from constructed fire lines intended to keep the fire from moving further into Arizona.
Tomorrow firefighters will continue to defend established lines while widening those barriers. Ambient temperatures along the border have exceeded 100 degrees with fuel conditions extremely dry. These conditions and steep terrain are challenging firefighters, but they are making steady progress.
Currently no structures are threatened.
Closures: Stage 2 fire restrictions are in place for the entire Coronado National Forest. These restrictions prohibit open fires, fireworks, and target shooting.
