The fresh snow and sometimes stormy westerly winds are resulting in snowdrift accumulations. On the northern Alpine ridge and in Valais these are in some cases becoming large, while elsewhere they are mostly medium-sized. Beneath the fresh and drifted snow, the old snowpack contains coarse-grained weak layers on steep north-facing slopes at highger altitudes.
Saturation of the snowpack is currently scarcely progressing. Wet snow avalanches that can sweep away the entire snowpack are therefore relatively rare. The most precarious areas remain north-facing slopes between 2200 and 2500 m.
