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

Increase in avalanche danger as a consequence of warming during the day and solar radiation. Weak layers in the old snowpack can still be released in isolated cases.

As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase. 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 south facing slopes also at elevated altitudes. Wet avalanches can occur in particular in starting zones where previous releases have taken place. Sometimes avalanches are medium-sized and can be released easily also by a single winter sport participant. In isolated cases dry avalanches can also 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 in case of a single winter sport participant. 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 on very steep west, north and east facing slopes above approximately 2400 m. Especially transitions from a shallow to a deep Snow deposited on the ground in a multiplicity of layers.EAWS glossary are unfavourable. Avalanches can penetrate down to the ground and reach medium size. Restraint should be exercised because avalanches can sweep people along and give rise to falls.

Outlook

Constant avalanche danger

8 April 2026

The avalanche danger will increase during the day.

Snowpack & Weather

Snowpack

Outgoing longwave radiation during the night will be quite good in some case. The surface of the Snow deposited on the ground in a multiplicity of layers.EAWS glossary will only just freeze and will already soften in the late morning. Sunshine and high temperatures will give rise to increasing and thorough wetting of the snowpack. The old 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 above approximately 2200 m. The snowpack will be subject to considerable local variations. On steep sunny slopes at low and intermediate altitudes hardly any snow is lying.
