    Abstract: Savoy's regional government manages more than 3000km of roads, including approximately 1000km over the elevation of 1000m. More than a hundred sections are threatened by avalanches, among them some providing access to some of the largest ski resorts in the world. In order to insure the management of real time avalanche risk, we were missing information on snow height and snow blowing. That's why Savoy's regional government invested in 6 additional remote stations, all of them measuring snow blowing, wind direction and speed, and air temperature. Four of them are also equipped for double snow height measurement. Indeed, a single measurement appears to be insufficient, especially at stations where wind parameters are also measured. While a first sensor is placed on the main station exposed to wind effect, a second one is located a few dozens meters away, rather protected from dominant winds. Resulting measurements are always interesting and sometimes unexpected. Furthermore, on one of the 4 sites, the second sensor, located close to a gas exploder, allows the measurement of avalanche activity by recording the sudden collapse of snow height if an avalanche is triggered. Real time measurements are available on the Internet.
