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.

Snowpack layer in which the crystals are poorly bonded and the layer has the potential to fail.

Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line. The Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are difficult to recognise. Isolated 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 can indicate the danger. Mostly avalanches are medium-sized. In addition the small wind slabs of the last few days adjacent to ridgelines are prone to triggering in isolated cases still, especially on very steep shady slopes at elevated altitudes. They are clearly recognisable to the trained eye.

Outlook

Increasing avalanche danger

19 February 2026

Increase in avalanche danger as a consequence of the new snow. The weather report and anticipated change in the avalanche danger are uncertain.

Snowpack & Weather

Snowpack

As a consequence of a strong wind from northwesterly directions, avalanche prone wind slabs formed especially 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. Somewhat older wind slabs 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.

Old snow layers consist of metamorphosed snow crystals.EAWS glossary. This applies in particular on west, north and east facing slopes.
