Field notes

Persistent Snowpack layer in which the crystals are poorly bonded and the layer has the potential to fail. Typical crystals in dry weak layers causing avalanches are : precipitation particles; surface hoar; faceted crystals; hollow crystals; graupel. Generally >1mm in size, loose grains with few bonds Wet weak layers can be formed by all snow crystal/grain types.EAWS glossary are very challenging to recognise. 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 and shooting cracks are typical when present, but you can have a serious weak layer with no warning signs at the surface. Knowledge of how the Snow deposited on the ground in a multiplicity of layers.EAWS glossary has evolved is essential. SLF's travel advice is direct: travel conservatively, avoid terrain where the consequences of being caught are large, and treat the history of weather and snow as more important than what you can see today.

Avalanche Activity

Increase in avalanche danger as a consequence of new snow and strong wind. The avalanche-prone wind slabs are lying on top of a weakly bonded old snowpack. They represent the main danger.

As a consequence of new snow and strong wind the wind slabs will increase in size additionally. The fresh and older wind slabs can be released very easily. They are barely recognisable. The Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are to be found in particular on southwest to north to southeast facing Direction in which a slope faces as indicated by compass direction of the fall line; i.e. a north slope faces in a northerly direction.EAWS glossary above approximately 2200 m and on steep south facing slopes above approximately 2400 m. In particular in shady places that are protected from the wind avalanches can release the weakly bonded old snow as well and reach quite a large size. Caution is to be exercised in particular at the base of rock walls and behind abrupt changes in the terrain, as well as 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. 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 and the formation of shooting cracks when stepping on the Snow deposited on the ground in a multiplicity of layers.EAWS glossary are a clear indication of a weakly bonded snowpack. As a consequence of solar radiation individual loose snow avalanches are possible from midday, but they will be mostly small.

Outlook

Constant avalanche danger

12 January 2026

Weakly bonded old snow represents the main danger.

Snowpack & Weather

Snowpack

15 to 25 cm of snow fell in the last few days. The strong wind has transported the new snow significantly. Up to 10 cm of snow will fall. As a consequence of the sometimes storm force wind the wind slabs will increase in size additionally. In some cases the various wind slabs have bonded poorly. The wind slabs are lying on top of a weakly bonded Snow layers deposited from earlier precipitation, prior to fresh fallen snow. Old snow layers consist of metamorphosed snow crystals.EAWS glossary. The old snowpack is faceted. The Snow deposited on the ground in a multiplicity of layers.EAWS glossary will be generally subject to considerable local variations. Only a small amount of snow is lying for the time of year in all altitude zones.
