Persistent Snowpack layer in which the crystals are poorly bonded and the layer has the potential to fail.

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.

Avalanche Activity

As the day progresses a dangerous avalanche situation will be encountered over a wide area. Wet snow represents the main danger.

In the early morning as a consequence of warming during the day and solar radiation there will be a rapid increase in the danger of wet avalanches. Most and wet avalanches can in isolated cases be released by a single winter sport participant. Caution is to be exercised in particular on very steep slopes below approximately 2500 m. As the penetration by moisture increases the prevalence of the Locations delineated by aspect or altitude where avalanches can trigger and people or objects are at risk.EAWS glossary will increase as the day progresses. More frequent wet 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 to be expected in the afternoon. Caution is to be exercised in particular on steep shady slopes between approximately 2200 and 2500 m. Especially here wet avalanches can be released in the weakly bonded old snow and reach large size. This also applies in isolated cases in highly frequented off-piste terrain. In steep Usually a steep, elongated, eroded trench; typically prone to snowdrift accumulation.EAWS glossary the avalanches can reach areas without any Snow deposited on the ground in a multiplicity of layers.EAWS glossary. Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m. Such avalanche prone locations are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable.

Outlook

Constant avalanche danger

16 April 2026

The surface of the snowpack will only just freeze and will soften quickly. 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
During the night the weather was clear at times. Outgoing longwave radiation during the night was quite good at times. Sunshine and high temperatures will give rise as the day progresses to increasing and thorough wetting of the Snow deposited on the ground in a multiplicity of layers.EAWS glossary below approximately 3000 m. The high humditiy will give rise in the afternoon to a loss of strength within the snowpack also on steep shady slopes. West, north and east facing slopes above approximately 2200 m: 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.
