This section is a document to help with the interpretation of the Avalanche Danger Bulletin.

Following the recommendation of the European Avalanche Warning Services (EAWS), the Avalanche Danger Bulletin is structured in an information pyramid. The basic information appears in the upper part: avalanche danger level and elevations and aspects prone to avalanches. In the central part, the current Typical Avalanche Problems and their description are shown. In the lower part other information related to the snow and weather conditions is indicated. The higher up the pyramid, the information is represented in graphic format and with very little text. As we go down, the information is more detailed in text format.

To know the meaning of the 5 danger levels, go to the European Avalanche Danger Scale.

In the Typical Avalanche Problems you can find the definitions, tactics, duration, typical signs, typical distribution and related travel advices.
