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.

Field notes

Rolling snowballs, deep penetration when you step or ski, and small natural slides are clear signals that the Snow deposited on the ground in a multiplicity of layers.EAWS glossary is losing strength. After a clear, cold night the surface often freezes into a strong supporting Layer of hard-compacted snow resulting from a melt-freeze process or wind.EAWS glossary, and conditions are favourable in the early morning. After a warm, overcast night, the problem may be present from the start of the day. Plan early returns and watch the runout zones below you.

Avalanche Activity

Weakly bonded old snow requires caution. Increase in danger of moist and wet avalanches in the course of the day.

Winter sport participants can release avalanches only in isolated cases. They can be triggered 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. Caution is to be exercised in particular on very steep 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. Especially transitions from a shallow to a deep Snow deposited on the ground in a multiplicity of layers.EAWS glossary are unfavourable. 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 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. As the day progresses as a consequence of warming during the day and solar radiation there will be a gradual increase in the danger of moist and wet avalanches. More frequent wet loose snow avalanches are to be expected, but they will be mostly small. This applies on extremely steep sunny slopes. Backcountry tours should be concluded early.

Outlook

Constant avalanche danger

6 April 2026

The avalanche danger will increase a little during the day.

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. Sunshine and high temperatures will give rise as the day progresses to significant moistening of the Snow deposited on the ground in a multiplicity of layers.EAWS glossary. The snowpack will be subject to considerable local variations. In steep terrain there is a danger of falling on the hard snow surface. In particular on steep sunny slopes at low and intermediate altitudes hardly any snow is lying.
