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

The hard wind slabs are lying on top of a weakly bonded old snowpack. The avalanche prone locations are rare.

Avalanches can be released, in particular by large loads and reach medium size. This applies in particular on very steep west, north and east facing slopes above approximately 2200 m. Especially transitions from a shallow to a deep Snow deposited on the ground in a multiplicity of layers.EAWS glossary are unfavourable. The Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are rare. In addition as the day progresses mostly small wet loose snow avalanches are possible. Caution is to be exercised in particular on extremely steep sunny slopes, and at the base of rock walls.

Outlook

Constant avalanche danger

5 April 2026

The high temperatures will give rise to increasing moistening of the snowpack.

Snowpack & Weather

Snowpack

The gusty wind has transported the fresh and old snow significantly. Hard wind slabs formed. These 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 in particular on west, north and east facing slopes above approximately 2200 m. The weather conditions will give rise to moistening of the Snow deposited on the ground in a multiplicity of layers.EAWS glossary.
