Fuels Involved

Timber (litter and understory)

Fire is burning in gray stage beetle killed lodgepole and subalpine fir with a high component of dead and down. Understory of grass and shrubs has a higher live fuel moisture content at this time and won't carry unless 1000-hr fuels are present.

Significant Events

Fire activity is minimal across the fire area.

Outlook

Planned Actions

Northern Fire Border: Wildland fire crews will continue monitoring for fire growth to the North. The heavy equipment crew that was working on the check line from MT Highway 279 to the Northcentral edge of the fire area broke down yesterday afternoon.

Southern Border of the Fire: Crews will continue to hold and strengthen existing control lines and monitor for hot spots. Rehabilitation efforts will focus on dozer lines associated with the North flank of the Black Diamond Fire.

Projected Incident Activity

12 hours: Minimal growth expected as isolated heat pockets continue to smolder.

24 hours: Cooler temperatures and higher humidity levels should moderate fire behavior. None-the-less, breezy conditions near ridge tops may lead to increased observation of smoke.

48 hours: Cooler temperatures and higher humidity levels should moderate fire behavior. None-the-less, breezy conditions near ridge tops may lead to increased observation of smoke.

72 hours: Cooler temperatures and higher humidity levels should moderate fire behavior. None-the-less, breezy conditions near ridge tops may lead to increased observation of smoke.
