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

Weakly bonded old snow represents the main danger.

Fresh and older wind slabs are prone to triggering. These can be released in the weakly bonded old snow, even by a single winter sport participant. Avalanches can reach medium size. 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 west to north to east 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. Individual avalanche prone locations are to be found also on steep south facing slopes above approximately 2600 m. Caution is to be exercised in particular 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 abrupt changes in the terrain, as well as on wind-loaded slopes. The avalanche prone locations are barely recognisable. Reports filed by observers and stability tests confirm a sometimes treacherous avalanche situation. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.

Outlook

Constant avalanche danger

26 January 2026

Some snow will fall. Slight increase in avalanche danger. The fresh and older wind slabs can be released by a single winter sport participant.

Snowpack & Weather

Snowpack

Some snow will fall, especially in the south. As a consequence of new snow and a moderate southerly wind, mostly small wind slabs will form. The fresh and older 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. They are bonding only slowly with the old snowpack. Distinct 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 exist in the old snowpack. The old snowpack consists of Snow grains, solid, with multiple flat glassy faces and sharp edges. Developed from faceting metamorphism, usually poorly bonded to one another (fewer contact points), a critical factor in avalanches if a faceted layer is covered with bonded snow. Typical grain size: 0.5 to 3 mm See also: www.snowcrystals.itEAWS glossary. The Snow deposited on the ground in a multiplicity of layers.EAWS glossary will be generally subject to considerable local variations. Steep sunny slopes: As a consequence of solar radiation a Layer of hard-compacted snow resulting from a melt-freeze process or wind.EAWS glossary formed on the surface during the last few days. Only a small amount of snow is lying for the time of year in all altitude zones.
