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

Weak layers in the old snowpack necessitate caution.

Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 2200 m. Mostly avalanches are medium-sized. 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, as well as at transitions from a shallow to a deep Snow deposited on the ground in a multiplicity of layers.EAWS glossary. The Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are covered with new snow and are difficult to recognise. The number and size of avalanche prone locations will increase with altitude. 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 snowpack can indicate the danger.

Outlook

Constant avalanche danger

31 January 2026

Avalanches can be released by a single winter sport participant.

Snowpack & Weather

Snowpack

10 cm of snow, and even more in some localities, has fallen. The new snow and 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 poorly bonded with the old snowpack. 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.
