YETI is a new web application designed to improve avalanche risk management. It helps snow sports practitioners in their choice of routes during the outing preparation phase, at home.

• YETI proposes an avalanche risk assessment on a cartographic interface. Like any evaluation, it can be imperfect or wrong. YETI evaluation errors can be related to the accuracy of the slope map (25 meters), the general information of the avalanche bulletin (at the scale of a massif) and the use of risk reduction based on probabilistic models
• YETI is a home race preparation tool that uses the main information available: snow report, slope maps, risk reduction methods. Once out in the snow, it will be necessary to keep a critical eye on the assumptions made at home. Only the reality of the field and the behaviour of the group will lead you to confirm or modify your choice of itinerary
• YETI, the slope map and the snow report are valuable tools for assessing conditions and terrain during race preparation. However, these tools do not focus on the group which is the third avalanche risk factor. Analysing the conditions and the terrain should not lead to neglecting the behaviour, level and experience of those who will go through it
• Snow sports outside marked trails remain risky activities requiring knowledge of avalanches and field experience to deal with the dangers of the mountain in winter. The practitioner remains solely responsible for his planning, his choices and his race on the snow
• The evaluations of YETI remain indicative and do not engage the responsibility of the Petzl Foundation, the IGN, the ENSG and the Camptocamp association, in case of direct or indirect damage resulting from their use and/or their inadequacy to the needs of the service user. It is up to the practitioner to take all necessary precautions for his safety during the outing and to comply with the directives and instructions of the competent national or local authorities
• It is strongly advised to read the FAQ (Frequently Asked Questions) before using YETI
