Ferguson Fire Update for August 10, 2018

Incident Start Date: 7/13/2018 Cause: Under Investigation Size: 95,544 acres Containment: 80%

Incident Type: Full Suppression Vegetation Type: Brush and timber

Unified Command Agencies: U.S Forest Service, National Park Service and Interagency Command Team 3

Resources Assigned: Engines: 104 Water Tenders: 14 Helicopters: 14 Crews: 17 Dozers: 20 Masticators: 5 Total Personnel: 1,532

Current Situation: Containment has increased to 80 percent. Firefighters are progressing towards full containment with the objective of keeping the fire out of Yosemite Valley. The final piece that must be secured remains between El Portal Road and Wawona Road. To secure this line, firefighters are implementing tactical burning operations along Wawona road north towards Turtle Dome. This operation is expected to take two or three days to complete. Night and day resources are focused on this operation. Progression will be slow and deliberate, when safe, due to the extremely dry vegetation and potential for spotting into the Grouse Creek Drainage. Aerial support from helicopters will assist firefighters on the ground to cool the fire and reduce the risk of fire spotting across the fire line.

Elsewhere on the fire, crews are patrolling the contained fire line. Suppression repair recourses are working to remove signs of suppression activity and prevent erosion.

Weather: Temperatures today will range between 97 and 106. However, relative humidity will be between 12 and 22 percent, slightly higher than previous days. This will be advantageous to firefighting efforts. The inversion will be present this morning. The smoke is not expected to clear until early afternoon.
