Field notes

Look for fresh snow deposits on Slope facing downwind/ wind sheltered aspect. Snow deposits can attain several times average snow depth.EAWS glossary, in Usually a steep, elongated, eroded trench; typically prone to snowdrift accumulation.EAWS glossary and Rounded or elongated concavity; typically tending to accumulate snowdrift.EAWS glossary, and behind ridgelines and abrupt changes in terrain — these are where the wind has loaded the snow into slabs that are easy to trigger. Recent avalanches, shooting cracks under your weight, and Distinctive noise (resembling a “whumpf” sound) occurring when a weak layer beneath a slab collapses. The air of the weak layer is forced outside the snowpack, with the resulting whumpf sound being heard. The sound usually indicates an unstable situation and can be accompanied by surface cracking. A whumpf is a clear avalanche alert.EAWS glossary sounds are clear confirmations of the problem. The safest move is to avoid wind-loaded terrain entirely. NB wind signs alone don't always mean an avalanche problem exists, and the age of drifted snow is hard to judge.

Avalanche Activity

Wind slabs require caution.

In particular adjacent to ridgelines as well as in Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary further wind slabs formed. This applies especially adjacent to ridgelines and in Usually a steep, elongated, eroded trench; typically prone to snowdrift accumulation.EAWS glossary and Rounded or elongated concavity; typically tending to accumulate snowdrift.EAWS glossary. The Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are rather rare and are clearly recognisable to the trained eye. The wind slabs of the last few days can be released easily above approximately 2200 m. Caution is to be exercised at their margins in particular. Mostly the avalanches are small. In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2600 m. In very isolated cases avalanches are medium-sized. Even a small avalanche can sweep snow sport participants along and give rise to falls.

Outlook

Constant avalanche danger

6 January 2026

The avalanche danger will persist.

Snowpack & Weather

Snowpack

The fresh and older wind slabs are lying on soft layers in particular on shady slopes. The Snow deposited on the ground in a multiplicity of layers.EAWS glossary will be subject to considerable local variations. In all regions a little snow is lying.
