      Abstract: The SERVICE DES PISTES DE TIGNES (Tignes Ski Patrol) began developing a computerized system with the help of Edouardo Garreaud in 1986, to explore new possibilities in avalanche forecasting. Snow-meteorological observations had been recorded since 1971. The goal was and is to process snow-meteorological observations in the most efficient way possible in order to present accurate conclusions for the community of Tignes (1550-3350 H). The ski area includes approximately 11,000 hectares of skiable terrain and over 125 lifts giving access to L'Espace Killy (Tignes and Val d'Isere). Tignes is situated in the inter-alpine zone, subject to a wide range of snow-meteorological conditions. - Snow-meteorological observations are recorded three times daily at Tignes Le Lac, 2080 H. - Observations recorded automatically at 2400 H. - Wind speed and direction recorded at 2700 M. - Weekly snowpack profiles at 2400 H. - Complimentary snowpack profiles. - Recording of all avalanche activity. - Observations are then entered into the computer. - Statistical calculations for similar days in the past. A practical result of this system is an analysis of the snow-meteorological situation for the past week and an evaluation of the local avalanche hazard each day. A bulletin is prepared to inform the general public. These evaluations are constantly verified in the field by the forecaster. This computerized system is still developing towards the ultimate goal of bringing together accurate local forecasting and efficient public communication, through for example, the use of local TV and minitel.
