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

The danger of wet avalanches will already increase in the late morning. Weak layers in the old snowpack can be released in some places by individual winter sport participants.

In the late morning as a consequence of warming during the day and solar radiation there will be a rapid increase in the danger of moist and wet avalanches. Avalanches can penetrate deep layers and reach large size in isolated cases. 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 in particular below approximately 2400 m, as well as on very steep west, south and east facing slopes at high altitude. Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary for dry avalanches are to be found on very steep shady slopes above approximately 2400 m. The avalanche prone locations are difficult 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 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. In steep terrain there is a danger of falling on the hard snow surface.

Outlook

Constant avalanche danger

10 April 2026

Outgoing longwave radiation during the night will be reduced. The avalanche danger will already be elevated in the early morning. This applies in particular below approximately 2400 m.

Snowpack & Weather

Snowpack

Outgoing longwave radiation during the night will be quite good. The surface of the Snow deposited on the ground in a multiplicity of layers.EAWS glossary 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. The snowpack will become increasingly wet all the way through. 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, as well as on steep sunny slopes at high altitude. Isolated avalanche prone 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 exist in the top section of the Snow layers deposited from earlier precipitation, prior to fresh fallen snow. Old snow layers consist of metamorphosed snow crystals.EAWS glossary. Towards its base, the snowpack consists of Snow grains, solid, with multiple flat glassy faces and sharp edges. Developed from faceting metamorphism, usually poorly bonded to one another (fewer contact points), a critical factor in avalanches if a faceted layer is covered with bonded snow. Typical grain size: 0.5 to 3 mm See also: www.snowcrystals.itEAWS glossary. This applies in particular on west, north and east facing slopes at high altitude, as well as on steep sunny slopes in Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary.
