Creeping

Moves slowly, hugging the ground.

Moderate

Spreads with low, steady flames.

Running

Runs along the ground much faster than a person walks.

Flanking

Torching

Whole trees flaring up like torches.

Isolated Torching

Single scattered trees flaring up whole, like torches.

Group Torching

Spotting

Wind carries embers through the air and starts new fires ahead of the front: that is how a fire jumps a road or a firebreak.

Wind Driven Runs
