Firefighters reacting to fire behavior changes rather than acting on potential.
Fire behavior not predicted or expected.
New situation negating safety margins.
How observations can be used to make predictions of flame length.
Step 1: Where will the fire get worse or easier?
Step 2: What are the threshold fire signatures?
Step 3: What force alignments caused these variations in flame length?
Step 4: Which fire signatures will replicate in the areas the fire has yet to burn ?
The Dillon Fire trigger point, track and first in alignment run predicted for 1630 happened @ 1730
The South Canyon Fire trigger point, track and in alignment run notpredicted happened @ 1630.
Trigger Point of Fire Behavior change
All three fires hit the trigger point and were then in full alignment with
wind, slope and solar preheat peaks.
Firefighters perishedbecause they did not understand the potential on the fire ground.
