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 and gliding snow require caution. In particular steep sunny slopes: Further increase in danger of wet avalanches as a consequence of warming.

In particular on very steep slopes medium-sized natural avalanches must be expected. In some places the avalanches can penetrate down to the ground and reach large size. Mostly the dry avalanches are medium-sized and can be released by a single winter sport participant. Remotely triggered avalanches are possible. 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 serve as an alarm indicating the danger. The Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are prevalent and are barely recognisable, even to the trained eye. Backcountry touring calls for meticulous route selection. 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 and reach large size in isolated cases. This applies even in case of a single winter sport participant. Caution is to be exercised in particular in little used terrain, as well as 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. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances. The no longer entirely fresh wind slabs remain for the foreseeable future prone to triggering in particular on steep west, north and east facing slopes above approximately 2400 m. As a consequence of warming during the day and solar radiation wet avalanches are to be expected. This applies in particular on very steep sunny slopes, and at the base of rock walls. The runout zones are to be treated with caution.

Outlook

Constant avalanche danger

28 February 2026

The snowpack remains prone to triggering over a wide area. The avalanche danger will persist. The activity of wet avalanches will gradually increase.

Snowpack & Weather

Snowpack
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 layers deposited from earlier precipitation, prior to fresh fallen snow. Old snow layers consist of metamorphosed snow crystals.EAWS glossary. The meteorological conditions will foster a gradual weakening of the Snow deposited on the ground in a multiplicity of layers.EAWS glossary on sunny slopes. The snowpack remains unstable over a wide area, especially adjacent to ridgelines and in pass areas in all altitude zones, as well as 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 at elevated altitudes.
