Abstract: Local avalanche services have to gain a quick overview of avalanche danger and snow condition. For this purpose, they have access to data retrieved by automatic stations and local observers employed by WSL Institute for Snow and Avalanche Research SLF. Own observations in combination with these data allow an estimation of the further development of the situation. The Swiss Syndicate of Avalanche Warning Systems (SILS) and SLF have developed a guideline describing the organization of an avalanche service and hazard evaluation. Additionally, a web application has been developed which supports this process and allows the documentation of decisions taken, e.g. road closure or the artificial avalanche release, together with the data retrieved and the hazard estimation made. The main goal of the application is to make the hazard evaluation as efficient and structured as possible. Second goal is to document the decisions taken. This application is intended as a support tool for local avalanche services. It can be customized and may be used additionally to own forms. It has been tested during winter 2007/08 and has gone operational in winter 2008/09. We inform about user feedback and give an outline of further development.
