Abstract: NivoLogis an avalanche forecasting support system designed to be daily used by forecasters or ski patrol men who have to secure mountainous regions, ski resorts, roads or railways. The system consists in several software components dedicated to data management, data analysis and data exchange. NivoLog database contains numerical information about weather, snowpack, topography, geography and observed avalanches. This information is structured according to a relational data model. In supplement to numerical information, NivoLog can process images such as maps or photos. NivoLog also includes an analysis module computing micro-regional avalanche risks (according to the standard European scale) and local avalanche probabilities. Expert knowledge and nearest cases are both used by the model. The forecaster can use actual measurements as well as scenarios to get either estimations or predictions. Finally, NivoLog can edit a short bulletin to be sent on the Web and to pagers. A new snow information service is now available: one can daily receive weather data and local avalanche risks on a watch. At present, developments consist in interfacing NivoLog with automatic sensors.
