Snowpack

The large amount of fresh snow from the current period of precipitation is falling in many places on an unfavourable old snowpack. Particularly on western, northern and eastern slopes, there are widespread pronounced weak layers in the snowpack where avalanches may start. In the Lower Valais and on the northern Alpine ridge, these weak layers are already somewhat more thickly covered than in other regions, but are still susceptible to triggering. On the southern flank of the Alps, in the Engadine and in central Grisons, the snowpack is mainly still thin, but consequently often completely faceted.
