An example of a presentastion of an avalanche problem in our bulletins. Please note that red areas indicate the most exposed terrain.

An avalanche problem, as presented in our bulletins, consists of these factors:

  • Expected weak layer to create avalanches
  • Advice - how to recognize and avoid the problem
  • A standard icon to illustrate the problem
  • Expected distribution of the avalanche problem in the terrain.
  • What type of avalanche is expected
  • Expected avalanche sizes
  • How easy can an avalanche be triggered

  • Probability for triggering an avalanche
