Pinal Fire Daily Update

Arizona Central West Zone Type 3 IM Team

Andrew Mandell, Incident Commander

May 15, 2017, 9:00 a.m. Information 928-487-0676

Detected: May 8, 2017 1500

Cause: Lightning

Current Size: less than75 acres

Containment: 0%

Location: Tonto National Forest, Globe Ranger District, 6 miles south

Globe Arizona, in the Pinal Mountains near Pioneer Pass burning in a

northerly direction.

Resources on Fire: The Central West Zone Type 3 Incident Management

There are 4 crews, 8 engines, 1 Type 3 helicopter and a total of 200

firefighters assigned to the incident.

A Temporary Flight Restriction that was placed over the fire was reduced

to a radius of 5 air miles from its center at Signal Peak and will remain

for the duration of the incident.

Operational Activities: The structure protection group will lay hose

and place ports tanks around the private land, homes and forest

improvements, water tenders will be available to fill tanks and plumb hose

lay. Crews have established a helispot near Pinal Peak.

Wildfire last burned in this area in 1952. The natural fire frequency of that

landscape is in need of the reintroduction of low-severity fire into the ecosystem to provide for fire adapted communities and infrastructure resulting in enhanced overall forest health for the future. One of the objectives of this incident is to restore ponderosa pine and mixed conifer fuel types to a more drought tolerant and natural condition while protecting the community water shed from erosion. Private land, infrastructure and recreation facilities will be protected from fire. Public and firefighter safety will remain paramount in all decisions and they are based on the values at risk.

Fuels: The major fuel types, found in and around the Pinal fire are long needle pine litter, conifer litter, grass, grass/shrub and shrub. The primary carrier of the fire at this time is long needle pine litter. Typical spread rates and flame lengths will be low to moderate in these fuel models.

Fire Behavior: Anticipate increased smoke visibility due to active fire behavior which will continue to spread upslope continuing to follow ponderosa pine and conifer stringers. Under clear skies with stable air mass expect to see low to moderate surface spread rates today through the timber understory, along with isolated single tree torching. Southwest terrain driven winds and steep slopes will dictate the direction of the spread.

Values at Risk: Private land and residences are in the vicinity of the wildfire area. Crews are protecting those homes through mechanical treatment and brush removal using chain saws and chippers. Electronic and communication sites are on Signal, Sulphide Del Ray, and Pinal Peak. Forest Service structures, campgrounds and infrastructure are present as are Mexican Spotted owl habitat and cultural and historic sites.

Restrictions & Closures: A closure order for the area has been established and will go into effect today at 6:00 am, please see linked document.

Special Concerns: Firefighter & public safety is the priority. Firefighting aircraft cannot fly if drones or remote control aircraft are in the air. Do not fly such aircraft within the temporary flight restriction area.
