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

Fresh wind slabs as the day progresses.

In the course of the day mostly small wind slabs will form. These 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. The small wind slabs are to be avoided in particular in terrain where there is a danger of falling. On steep grassy slopes individual gliding avalanches are possible, but they will be mostly small.

Outlook

Constant avalanche danger

7 December 2025

Wind slabs are small and can only be released in isolated cases.

Snowpack & Weather

Snowpack

Over a wide area 10 cm of snow has fallen. As a consequence of a moderate westerly wind, small wind slabs will form in the course of the day at elevated altitudes. These 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. See also: www.snowcrystals.itEAWS glossary in some places. Shady slopes: The Snow layers deposited from earlier precipitation, prior to fresh fallen snow. Old snow layers consist of metamorphosed snow crystals.EAWS glossary is largely stable. The older wind slabs of the last few days have bonded quite well with the old snowpack. They are now only very rarely prone to triggering.
