The official Swiss avalanche bulletin is published by the avalanche warning service of the WSL Institute for Snow and Avalanche Research SLF. A description of this publication is given in 'Information about the avalanche bulletin' on the website www.slf.ch. Only the most recent version is binding. 'Information about the avalanche bulletin' does not go into the details of supporting products such as snow maps and measured data, which can be found with the relevant products, nor does it give a description of the Information Platform for Natural Hazards (GIN) or the special products on offer there to safety services. The SLF provides training courses for safety personnel which give them a greater understanding of these products.
