The danger description that forms part of the avalanche bulletin cites the predominant avalanche problems as well. The purpose of this is to focus attention on the main aspects. This practice capitalises on the human brain's capacity to recognise and interpret recurring characteristics. Each avalanche problem has a different cause and calls for a specific response tailored to the relevant situation.
The avalanche bulletin describes only avalanche problems – no more than three together – contributing substantially to the overall danger.
The avalanche problems cited in the avalanche bulletin, and the criteria applied by the avalanche warning service when they are cited, are described briefly below.
