Abstract: Local avalanche forecasters have to take daily decisions like "I keep this road open", "No access to this valley today", or "The ski runs must be closed now". Such decisions are very difficult to take because of their human and economic impacts ! Since the 80's, the Swiss Federal Institute for Snow- and Avalanche Research is working on this subject, and has now developed a specific strategy and some tools to help practitioners. The main aspects of this strategy are: research, information, instruction, technical assistance, and coordination. Its strength comes from a constant communication between researchers who design instruments, sensors and software, and· practitioners who test them and participate in the developments by giving their own ideas and a regular feedback. At the present time, a new diagnosis support system called NXLOG 2.0 is born from this cooperation. It is the result of merging two existant and proven systems: NXD which uses data analysis procedure (nearest neighbours method) and AVALOG which exploits artificial intelligence techniques. NXLOG 2.0 includes machine learning functions in order to improve its reliability as long as its database expands. It has been implemented on PC, and will run and be tested from the beginning of winter 1994-95 in about 20 . European ski resorts (in France, Italy, Scotland, Spain, and Switzerland). In the near future, the system may be used by an increasing number of partners.
