Fresh and older wind slabs require caution.

Avalanches can be released in the old snowpack and reach dangerously large size. The avalanche prone locations are to be found in particular at transitions from a shallow to a deep snowpack above approximately 2200 m and in areas where the snow cover is rather shallow. These places are quite prevalent and are difficult to recognise. In addition the no longer entirely fresh wind slabs should be taken into account. The current avalanche situation calls for caution and restraint. Slight increase in danger of dry and wet avalanches as a consequence of warming during the day and solar radiation. As the penetration by moisture increases individual gliding avalanches and moist snow slides are possible below approximately 2600 m.

Snowpack

In some cases the wind slabs have bonded still only poorly with each other and the old snowpack. Wind slabs are clearly recognisable to the trained eye. They are widespread. Faceted weak layers exist in the old snowpack, in particular in areas where the snow cover is rather shallow as well as adjacent to ridgelines above approximately 2200 m.

Tendency

Slight decrease in danger of dry avalanches.

Danger level
Danger Level 2 - Moderate
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-W-NW
Gliding snow above 2600m, N-NE-E-SE-S-SW-W-NW


The fresh and older wind slabs can still be released in some cases.

Small and medium-sized avalanches are possible. This applies in particular in gullies and bowls, and behind abrupt changes in the terrain, caution is to be exercised in particular at transitions from a shallow to a deep snowpack. Below approximately 2600 m more small and, in isolated cases, medium-sized gliding avalanches are possible.

Snowpack

The wind slabs have formed in particular in gullies and bowls, and behind abrupt changes in the terrain. They are in some cases extensive and to be assessed critically. In some cases the various wind slabs have bonded still only poorly together. The old snowpack remains moist below approximately 2000 m.

Tendency

Moderate, level 2.
