The Avaluator has underwent a few changes in 2010. The Slope Evaluation card for this updated Version has a new matrix that correlates field observations about avalanche conditions with terrain factors.
Avaluator – Slope Evaluation
Avalanche Canada – Avaluator Slope Evaluation graph
As you review both the Avalanche Conditions Warning Signs and the Terrain Characteristics notice that some relate to increased probability of triggering an avalanche and some relate to increased consequences if one is triggered.
This makes sense when one considers this definition of Risk:
Risk = Probability * Consequence * Exposure * Vulnerability
