Field notes

Persistent weak layers

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.

Wind slab

Look for fresh snow deposits on Slope facing downwind/ wind sheltered aspect. Snow deposits can attain several times average snow depth.EAWS glossary, 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 ridgelines and abrupt changes in terrain — these are where the wind has loaded the snow into slabs that are easy to trigger. Recent avalanches, shooting cracks under your weight, and 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 are clear confirmations of the problem. The safest move is to avoid wind-loaded terrain entirely. NB wind signs alone don't always mean an avalanche problem exists, and the age of drifted snow is hard to judge.

Avalanche Activity

Wind slabs and weakly bonded old snow require caution.

Weakly bonded old snow is to be evaluated with care and prudence. These 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 in northwest to north to northeast 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. Caution is to be exercised in particular on very steep shady slopes above the tree line, as well as at transitions from a shallow to a deep Snow deposited on the ground in a multiplicity of layers.EAWS glossary, when entering 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 for example. The wind slabs can be released, especially by large additional loads, in particular on west to north to east facing aspects above the tree line. Avalanches can also release deeper layers of the snowpack and reach quite a large size. As a consequence of warming during the day and solar radiation individual mostly small moist loose snow slides are possible. This applies on very steep slopes at the base of rock walls.

Outlook

Constant avalanche danger

26 March 2026

The avalanche danger will persist.

Snowpack & Weather

Snowpack

As a consequence of a sometimes strong wind from variable directions, sometimes avalanche prone wind slabs formed in the last few days. The fresh and somewhat older wind slabs are lying on the unfavourable surface of an Snow layers deposited from earlier precipitation, prior to fresh fallen snow. Old snow layers consist of metamorphosed snow crystals.EAWS glossary. 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.

This applies especially above approximately 2000 m.
