Crews were able to make good progress as moisture and precipitation remained mostly north of the fire area.
Operations: Yesterday, crews on the northwestern portion of the fire area cleaned up containment lines and looked for alternative containment options to avoid sparse fuel areas. On the eastern portion of the fire area, crews scouted some areas near the 411 road and 512 road intersection, held current lines, and worked on backing fire down some of the ridges. Today, crews will continue with prep work to the northwest, while crews to the east look to bring fire up from the 411 road to meet the backing fire moving south down some of the ridges. Some resources may be rotating out and new resources rotating in over the coming days.
Fire Ecology: When fire heats up leaves or needles on trees, the water in them expands, bursting the cell walls so they can no longer function. This exposes the leaf material to more oxygen causing the leaf material to begin to oxidize, and also allows the water that was in the cells to evaporate. Scorch is sometimes used as a measure for fire severity.
Weather: Yesterday, moisture formed but stayed mostly north of the fire area with a few scattered storms. Today, conditions will be similar as temperatures remain cool and possible scattered storms over the fire area. Moisture is expected to move out Wednesday night as a drying trend begins Thursday with only a slight chance of isolated showers through the weekend.
