Snowpack
The drifting snow layers of the last few days are still prone to triggering in places. The snowpack is locally highly variable and the snow depths vary greatly depending on wind exposure. With the clear nights, in many places faceting is beginning to occur in the snowpack.
On the northern Alpine ridge, in Valais, in the Gotthard region, in northern and central Grisons and in Engadine, there are weak layers in the snowpack below December’s fresh snow. These are mostly located near melt-freeze crusts, especially on north- and east-facing slopes. Avalanches may be triggered in these weak layers.
