What is the meaning of the European avalanche warning scale?


The European avalanche warning scale is 5 step scale which is used to classify the potential danger of avalanches.


Important to know is that one step further is not done with the same measure, every step is exponential bigger than the one before.


The avalanche warnings are part of the avalanche situation reports of the particular avalanche warning services in the alpine region published regional. The appraisal must always be checked before starting a tour or a free ride, because the risk of danger can change very fast influenced by diverse conditions.  These abilities to check the risk of avalanches and the reading of the avalanche warning scale is part of a fundamental qualification.

3 (considerable)
An avalanche is possible in cases of low additional load especially on the listed steep slopes.  Spontaneous some moderate avalanches and also a few large ones are expected.
