Snowpack Structure

Snowpack

A lot of new snow and snowdrift in the south is prone to triggering. Before the snowfall, the old snow surface was mostly irregular. However, it was also angular in places, especially on north-facing slopes at a distance from ridgelines and sheltered from the wind.

In the north, since Friday strong southerly winds have led to the formation of wind slabs, some of which are prone to triggering. These will be covered with new snow on Sunday.

Gliding avalanches are still to be expected. This applies particularly to east-, south- and west-facing slopes below approximately 2600 m and more rarely to north-facing slopes below approximately 2200 m. These avalanches may be large in some cases in regions with a lot of snow.
