Avalanches may occur. Medical search. Frequent questions

Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. (wikipedia.org)
Slab avalanches form frequently in snow that has been deposited, or redeposited by wind. (wikipedia.org)
