Snowpack Structure

Up to intermediate altitudes rain has fallen since Saturday. Over a wide area new snow is lying on a moist old snowpack. The surface of the snowpack will cool hardly at all during the overcast night. The sleet will give rise to increasing moistening of the snowpack in particular at intermediate and high altitudes. Isolated avalanche prone weak layers exist in the snowpack at high altitudes and in high Alpine regions. Below approximately 2000 m a little snow is lying.

Tendency

Persistent snowfall to intermediate altitudes. As the precipitation becomes more intense there will be a gradual increase in the avalanche danger.

Avalanche Activity

The weather conditions will give rise to extreme moistening of the snowpack over a wide area.

Up to 10 cm of snow, but less in some localities, has fallen since Saturday above approximately 2500 m. Up to intermediate altitudes rain will fall today over a wide area. In the regions exposed to precipitation the avalanche prone locations will become more prevalent. In particular on very steep slopes more small and medium-sized moist and wet avalanches are possible as a consequence of the precipitation. Individual weak layers exist in the old snowpack in particular at high altitudes and in high Alpine regions. Avalanches can also be triggered in the old snowpack and reach quite a large size.
