The AvaBlog and the winter reports are published in German and French. They review the weather, snowpack and avalanche danger, as well as selected accidents which have given rise to personal injury and property damage. Together they comprise a complete record of conditions throughout each hydrological year. The hydrological year runs from 1 October until 30 September.
AvaBlog and weekly reports
In wintertime the reports appeared weekly until 2021/22, since 2022/23 according to the situation as AvaBlog. To select a report for a specific period, please go to the page in German or French.
Given that the SLF has been issuing winter reports since the winter of 1936/37, a long-term and valuable series of documents is now available. They review the hydrological year, draw comparisons with long-term averages, and analyse exceptional winter occurrences in additional supplementary chapters. An initial provisional issue of the winter report appears around the end of April. Numerous updates are published thereafter.
