Escaped fire in both prescribed and wildfire situations holds over during the night and burns again the next day. Humidity recovery is generally insufficient to extinguish heavier fuels, resulting in a large number of hold-over fires. Increased mop-up and patrol activities are required. Direct attack on wildfires is difficult due to intensity. Topographic features used for lines in prescribed fire and wildfire suppression will hold, but smaller drains begin to dry up, and drifted debris is dry enough to allow fires to creep across drains.
Swamps begin to show reduced water levels.
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.
