News – 9/4/2020

  Hidden Fire – September 3, 2020 Morning Update

Acres: 6107Percent
Containment: 29%
Start Date: August 25, 2020

Injuries: 0 Cause: Lightning

Origin Location: Sierra Ancha Mountains, Tonto NF

Successful Firefighting Operations Continue on the Hidden Fire

YESTERDAY: There was no growth on the fire yesterday. Helicopter bucket drops kept areas of heat in check. Crews continued to work on securing, patrolling and mopping up containment lines. Warmer weather and lower humidity caused increased fire activity within the perimeter as expected. The increase in heat ignited unburned interior pockets of fuel in burnout areas, helping to secure containment within the existing footprint.

TODAY’S ACTIVITY: Warmer weather today will continue to support burning operations, as interior pockets of brushy fuel ignite and burn out, lessening the potential for fire growth beyond containment lines. Firefighters will continue their focus on securing and mopping up fire lines. Masticators will be used for suppression repair work in areas where contingency and protection work was completed.

AIR SUPPORT: Due to the increased fire activity throughout the Southwest and California air support is limited. We are utilizing shared resources of air tankers and helicopters with our neighboring Type 1 Incident Management Team.
