Generally, all surface litter and most of the organic layer is consumed by fire. This will result in a massive amount of smoldering fire in the burned area. Dead snags ignite. Large dead snags will create a safety hazard due to the potential for falling. Spotting is difficult to control.
Escaped fire continues to burn through the night and into the next day.
Burns leave excessive site damage. Direct attack is generally not effective due to increased intensity and spotting. Extreme intensities add to the control efforts. Some nighttime activity can be extreme, dependent on the fuels available. Fire personnel should expect and prepare for the previous day's fire to escape the next day during the peak burning period.
