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.

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.

Avalanche Activity

Weak layers in the upper part of the snowpack can be released in some places by people. Rapid increase in danger of moist and wet avalanches in the course of the day.

Avalanches can in some cases be released in near-surface layers and reach medium size. Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are to be found especially on very steep west, north and northeast facing slopes between approximately 2200 and 2800 m. Individual avalanche prone locations are to be found also on very steep sunny slopes in Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary. 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. Remotely triggered avalanches are possible in isolated cases. Avalanches can in very isolated cases penetrate near-ground layers of the snowpack and reach large size. As the day progresses as a consequence of warming during the day and solar radiation there will be an appreciable increase in the danger of moist and wet avalanches. More frequent wet loose snow avalanches are to be expected, in particular medium-sized ones. This applies on extremely steep sunny slopes. Individual moist The abrupt release of a slab of snow on a mountain slope. After crack initiation and crack propagation in a weak layer the released slab comprises 3 elements: The weak layer, the gliding horizon and the slab. If the slope angle is steep enough, the slab will glide down. If the slope is not steep enough, the slab will settle down on the failed weak layer. Possibly a whumpf sound will follow due to air pressed out of the weak layer. The fracture line will be sharp edged.EAWS glossary are possible, in particular medium-sized ones. This applies in particular on very steep west and east facing slopes in particular between approximately 2200 and 2800 m. 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

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, especially on west, north and northeast facing slopes between approximately 2200 and 2800 m, and on sunny slopes in Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary. Towards its base, the Snow deposited on the ground in a multiplicity of layers.EAWS glossary 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, in particular on west, north and east facing slopes at elevated altitudes. The surface of the snowpack will soften quickly. Sunshine and high temperatures will give rise as the day progresses to gradual and thorough wetting of the snowpack.
