Image options: [ Enlarge ] [ Full Size ]


Overcast skies and higher relative humidity resulted in minimal fire behavior yesterday. Insignificant fire spread is expected again today as it continues backing slowly downslope to the west.

Construction of indirect fire control lines along the southwest and southeast side of the fire continues with the assistance of hand crews and heavy equipment. The presence of the heavy equipment, falling trees and fire personnel conducting chainsaw work can be dangerous to the public. For this reason and for the safety of firefighters, area and road closures continue to remain in effect.

Posted photos of indirect fire line construction can be viewed on inciweb as reference of what is being done on the ground.

Crews will be meeting with homeowners in the communities near the fire to discuss best firewise practices. Residents can play a role by creating a defensible space around their home.
