Various conditions have to be fulfilled to facilitate the formation of an avalanche. A slab avalanche cannot occur unless a weak layer covered by a slab-like sheet of snow exists over a sufficiently large area, unless the terrain is steep enough (> 30°), or in the absence of an additional load capable of triggering the initial failure.

 

Some simple rules that can be applied when assessing the avalanche danger:
