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 danger of wet avalanches in the course of the day.

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 wet avalanches. Wet avalanches can in some places be released by a single winter sport participant. This applies on very steep shady slopes below approximately 2500 m, as well as on very steep sunny slopes at elevated altitudes. Natural avalanches are possible in the afternoon. Avalanches can be released in the weakly bonded old snow and reach large size in isolated cases. Dry avalanches can additionally be released, even by small loads in isolated cases, especially on very steep west, north and east facing slopes above approximately 2500 m. Especially transitions from a shallow to a deep Snow deposited on the ground in a multiplicity of layers.EAWS glossary are unfavourable. The Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary are difficult to recognise. The no longer entirely fresh wind slabs can be released by a single winter sport participant in isolated cases in particular on very steep shady slopes in Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary.

Outlook

Constant avalanche danger

18 April 2026

Outgoing longwave radiation during the night will be good. The backcountry touring conditions in the morning at elevated altitudes are generally favourable. As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of wet avalanches.

Snowpack & Weather

Snowpack

The surface of the Snow deposited on the ground in a multiplicity of layers.EAWS glossary 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. Sunshine and high temperatures will give rise to increasing and thorough wetting of the snowpack below approximately 3000 m. Steep west, north and east facing slopes: Faceted 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 at elevated altitudes.
