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

Slight increase in avalanche danger in the course of the day. Fresh wind slabs represent the main danger.

The fresh wind slabs are mostly small but can in some cases be released easily. The somewhat older wind slabs can be released in isolated cases on very steep shady slopes at elevated altitudes. The Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are to be found 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 and on very steep shady slopes above approximately 2400 m. The mostly small wind slabs are to be avoided in particular in terrain where there is a danger of falling. Afternoon: Slight increase in danger of gliding avalanches and snow slides as the snowfall level rises.

Outlook

Increasing avalanche danger

8 December 2025

Further increase in avalanche danger as the precipitation becomes more intense.

Snowpack & Weather

Snowpack

Up to 2200 m rain will fall in the afternoon in some regions. As a consequence of a moderate to strong wind from westerly directions, sometimes avalanche prone wind slabs will form at high altitudes and in Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary. The wind slabs are lying on soft layers on shady slopes. They are lying on Transparent, frequently flat crystals forming on the snowpack when moist air settles on the surface. It forms most often during cold, clear, humid nights. Once it is blanketed by fresh fallen snow, surface hoar is one of the most critical weak layer.
