Avalanche Activity

Wind slabs and weakly bonded old snow represent the main danger.

In particular at intermediate and high altitudes sometimes avalanche prone wind slabs formed. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack in particular on steep shady slopes above approximately 2200 m. Single winter sport participants can release avalanches in some places. The avalanche prone locations are to be found in particular on steep northwest to north to northeast facing slopes and in places that are protected from the wind. Off-piste activities call for experience in the assessment of avalanche danger. As a consequence of warming during the day and solar radiation dry and moist avalanches are possible as the day progresses, but they will be mostly small.

Snowpack Structure

40 cm of snow, and even more in some localities, has fallen since Sunday above approximately 2000 m. Weak layers exist in the snowpack in particular at intermediate altitudes. Over a wide area new snow is lying on a hard crust. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack in particular on very steep sunny slopes below approximately 2400 m.

Tendency

Little snow will fall on Sunday.
