Appenzeller Alpen — Bulletin d'avalanche

SnowpackWith the mild weather, partly overcast nights and rain in places, moistening of the snowpack continued over the course of the last week. On south-facing slopes the snowpack is water-saturated up to around 3000 m, and on east- and west-facing slopes up to 2500 to 2700 m, while on north-facing slopes it is water-saturated below 2000 m, with moistening progressing between 2000 and 2400 m.In the south, fresh and drifted snow at high altitudes is prone to triggering, especially on shady slopes. Avalanches can also in some cases still be triggered by human activity in faceted weak layers in the old snowpack. Such danger zones are generally located at altitudes where the snowpack is becoming moist for the first time. In central Valais and in Grisons in particular, such avalanches can in some cases entrain the entire snowpack, especially on slopes with light snow cover.
