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

From early morning the likelihood of wet avalanches being released will increase quickly. Weakly bonded old snow requires caution.

As a consequence of warming during the day, the likelihood of moist and wet avalanches being released will increase significantly in particular on steep sunny slopes. This applies in all 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 below approximately 2400 m, and on steep south facing slopes also at high altitude. Wet avalanches can occur easily or triggered naturally. These can also penetrate down to the ground and reach medium size. Dry avalanches can 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, this applies even in case of a single winter sport participant in some cases. They can penetrate down to the ground 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. 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. Especially transitions from a shallow to a deep Snow deposited on the ground in a multiplicity of layers.EAWS glossary are unfavourable.

Outlook

Constant avalanche danger

10 April 2026

Outgoing longwave radiation during the night will be reduced in some case. The avalanche danger will persist.

Snowpack & Weather

Snowpack

Older wind slabs 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 at high altitudes and in Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary. The Snow deposited on the ground in a multiplicity of layers.EAWS glossary will be subject to considerable local variations. Outgoing longwave radiation during the night was good over a wide area. The surface of the snowpack has frozen to form a strong Layer of hard-compacted snow resulting from a melt-freeze process or wind.EAWS glossary only at high altitudes and will already soften in the late morning. Sunshine and high temperatures will give rise as the day progresses to increasing and thorough wetting of the snowpack. On very steep sunny slopes and at the base of rock walls the snowpack will soften quickly. On sunny slopes at low and intermediate altitudes hardly any snow is lying.
