|Projected Incident Activity|
12 hours: Nighttime conditions will minimize fire heavier tonight. Islands of unburned fuels in the perimeter will burn in the presence of moderate to heavy surface fuel. Crews will continue to patrol the fire perimeter overnight where applicable and safe.
24 hours: Red Flag Warning for dry north winds and low relative humidity is forecasted, which could increase the risk of spot fires and may cause holding concerns for the south end of the fire. Rollout remains the prominent methods of fire spread. Islands of unburned fuels in the perimeter will burn in the presence of moderate to heavy surface fuel. Crews continue to patrol the western perimeter of the fire and where applicable. Mopup will continue progress deeper within the perimeter. Suppression repair is beginning in areas where the threat of fire escape has been mitigated.
48 hours: Reduced winds will return to moderated fire behavior. Interior pockets will continue to burn. Rollout remains the prominent methods of fire spread. Islands of unburned fuels in the perimeter will burn in the presence of moderate to heavy surface fuel. Crews continue to patrol the western perimeter of the fire and where applicable. Mopup will continue progress deeper within the perimeter. Suppression repair is beginning in areas where the threat of fire escape has been mitigated.
