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. Read the full bulletin.

New snow

Easy to spot - the snow is fresh. Look at recent avalanche activity in similar terrain, and pay attention to how much new snow has fallen in the last three days. Critical loading depends on temperature, wind, and what was on the surface before the storm. SLF advises waiting until the Snow deposited on the ground in a multiplicity of layers.EAWS glossary has had time to bond before committing to steep terrain in fresh snow.

Avalanche Activity

Weakly bonded old snow requires caution. New snow and wind slabs require caution.

Avalanches can in some cases be released in the Snow layers deposited from earlier precipitation, prior to fresh fallen snow. Old snow layers consist of metamorphosed snow crystals.EAWS glossary and reach medium size, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes. 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 Snow deposited on the ground in a multiplicity of layers.EAWS glossary can indicate the danger. Remotely triggered avalanches are possible in isolated cases. The wind slabs can be released by a single winter sport participant in isolated cases above approximately 2200 m. Such 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 therefore difficult to recognise. 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. Avalanches can reach medium size. In addition small and medium-sized loose snow avalanches are possible, in the event of prolonged bright spells especially on extremely steep slopes.

Outlook

Decreasing avalanche danger

4 April 2026

New snow and weakly bonded old snow are to be assessed with care and prudence.

Snowpack & Weather

Snowpack

The Snow layers deposited from earlier precipitation, prior to fresh fallen snow. Old snow layers consist of metamorphosed snow crystals.EAWS glossary will be weakly bonded in some places, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes in Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary. Some snow will fall in some regions. The sometimes strong wind has transported the fresh and old snow. In some cases the various wind slabs have bonded still only poorly together.
