The SLF weekly report

The WSL Institute for Snow and Avalanche Research SLF, which has grown into a renowned research institution since 1936, now employs almost 150 people in Davos, Switzerland. In addition to its best-known service, the Avalanche Bulletin, the SLF conducts both basic and applied research and also provides a so-called weekly report in winter. This represents great added value, especially for us winter sports enthusiasts, as it contains important (background) information on the snow and avalanche situation.

In addition to text and photos, the weekly report offers thematic maps and measured values that provide an even more precise basis of information, especially for interested readers. For example, weather maps, amounts of new snow and snow profiles are included in the weekly reports. In conjunction with the avalanche bulletin, this allows winter sports enthusiasts to assess the avalanche and snow situation even more accurately.

In winter - from mid-December to the end of May - the weekly report is published weekly on Thursday evenings in German and the following day in French. In early winter, a report is published for the periods November 1-30, December 1-12, 2019 and December 13-19. In the summer months, the report is published monthly, at the beginning of the following month.

These monthly or weekly reports provide a complete documentation of the hydrological year (01.10-30.09), which can be accessed on the website of the SLF. This comprehensive documentation can be accessed back to the winter of 2002/03.

The SLF winter report

In addition to the weekly reports, the SLF publishes a winter report every year that covers the entire previous hydrological year. In this report, the weather, snow cover, avalanche risk and selected accidents are discussed and analyzed. In addition, a comparison is made with the long-term average values, allowing particular "characteristics" of the winter to be highlighted and analyzed. These records have existed since 1936 and thus form a valuable series of documentation spanning many years.

An overview of the winter reports can be found on the SLF website. The reports from previous years can be downloaded from the DORA database.
