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.

Avalanche Activity

Weakly bonded old snow requires caution.

Distinct 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 bottom section of the Snow deposited on the ground in a multiplicity of layers.EAWS glossary in particular above approximately 2000 m. Winter sport participants can release avalanches as before. These can reach large size, especially on west, north and east facing slopes. Individual Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are to be found also on southeast, south and southwest facing slopes above approximately 2400 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering 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 for example. Remotely triggered avalanches are possible. Outgoing longwave radiation during the night will be reduced at times. As a consequence of warming during the day and solar radiation individual mostly small wet loose snow avalanches are possible below approximately 2200 m. In addition gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 2400 m.

Outlook

Constant avalanche danger

4 March 2026

Weakly bonded old snow requires caution. Increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.

Snowpack & Weather

Snowpack

The Snow deposited on the ground in a multiplicity of layers.EAWS glossary remains prone to triggering. 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 bottom section of the snowpack on west, north and east facing slopes. The surface of the snowpack will freeze to form a strong Layer of hard-compacted snow resulting from a melt-freeze process or wind.EAWS glossary and will soften during the day.
