Significant Events

Moderate

Flanking

Backing

Isolated torching

Fire continues to back and flank, burning pockets of vegetation inside control lines. Isolated torching occasionally occurring where fire has rolled out and reheated later fuels.

Outlook

Planned Actions

Hold previous firing operations, implement firing operations on indirect control lines as conditions allow, provide structure defense where necessary, continue mop-up along the fire perimeter, locate and document opportunities for suppression repair, patrol and stabilization of incident.

Projected Incident Activity

12 hours: Rollout remains the prominent method of fire spread and slop-overs; torching near ridges could produce spot fires during the hottest part of the day. Islands of unburned fuels in the perimeter will burn in the presence of moderate to heavy surface fuel. Firing operations are expected to be completed. As mop-up activity deepens within the fire perimeter, the chance of spot fires via rollover will be reduced. Crews will continue to patrol the western perimeter of the fire.

24 hours: Rollout remains the prominent method of fire spread and slop-over. However, dry north winds 10-15 mph gusting to 25 and low relative humidity is forecasted for this operational period, which could increase the risk of spot fires and may cause holding concerns for the south end of the fire. Crews will continue to patrol the western perimeter of the fire. Mop-up will continue to progress deeper within the perimeter. Suppression repair is beginning in the areas where threat of fire escape has been mitigated.

48 hours: Rollout remains the prominent method of fire spread and slop-over. However, dry north winds 10-15 mph gusting to 25 and low relative humidity is forecasted for this operational period, which could increase the risk of spot fires and may cause holding concerns for the south end of the fire. Crews will continue to patrol the western perimeter of the fire. Mop-up will continue to progress deeper within the perimeter. Suppression repair is beginning in the areas where threat of fire escape has been mitigated.

72 hours: Rollout remains the prominent method of fire spread and slop-overs. Islands of unburned fuels in the perimeter will burn in the presence of moderate to heavy surface fuel. AS mop-up activity deepens within the fire perimeter, the chance of spot fries via rollover will be reduced. Continued mop-up and patrol where applicable. Suppression repair continues in areas where threat of fire escape has been mitigated.

Anticipated after 72 hours: Same as previous days.

Current Weather

Weather Concerns

OBSERVED: Light smoke continued to be trapped under an inversion. Low temperatures Wednesday morning were 52-57 degrees on the ridges and 47-52 degrees in the drainages. Maximum relative humidity values were 42-47 percent on the ridge tops and 50-55 percent in the drainages. South to southwest winds continued in the evening hours, becoming north and strengthened through the night.

FORECASTED: Wednesday, temperatures will be warmer, with afternoon highs ranging from 74-79 degrees on the ridgetops to 81-86 in the lower drainages. The dry conditions will continue as afternoon minimum relative humidity values drop into the 15-20 percent range across the ridges and 11-16 percent in the drainages. Winds will remain from the north the entire day, increasing to 9-14 mph, with gusts up to 25 mph. Higher gusts than previous days will be likely in north-south aligned drainages, such as the Interstate 5 Corridor. A Fire Weather Watch has been issued for Wednesday evening through Thursday afternoon for overnight gusty winds and poor relative humidity recoveries.
