Shamrock Fire Update 06/12/2021

Shamrock Fire Wildfire
News – 6/12/2021

Shamrock Fire – June 12, 2021 Update

Acres: 1,104 acres

Start Date:  June 9, 2021

Cause: Under Investigation

Containment: 48%

Total personnel: 177

Location: 11 miles northeast of Nogales, AZ

Fuels: Short grass and brush

Operations: Infrared Operations were conducted last night to map hot spots and the fire perimeter.  The acreage of the fire was reduced due to the increased accuracy of the mapping method conducted by the flight.

Minimal fire activity occurred today on the Shamrock Fire. Some smoke may have been observed from some minor torching of the fuels remaining inside the green islands left within the fire perimeter. Firefighters worked throughout the day to mop up edges of the fire perimeter to secure the line. Extreme temperatures, dry conditions, and steep, rugged terrain continue to be a challenge to the firefighters. Health and safety of firefighters and the public is the first priority.

The resources assigned include: 6 Crews, 5 engines, 2 Helicopters, 2 Air Attack, and miscellaneous overhead.

Weather: Record heat is expected in southern Arizona through the upcoming week. Very dry conditions this weekend with very poor overnight relative humidity recoveries. Winds are expected to increase in the afternoons.

Restrictions:  A Temporary Flight Restriction is in place over the Shamrock Fire to ensure safe air operations. Due to increased fire activity and dry conditions, Stage 2 fire restrictions are currently in effect in southeastern Arizona. Forest visitors are reminded to comply with all restrictions to help reduce the risk for human-caused wildfire.
