Regions
Prealps, Vallarsa


Danger level
Danger Level 3 - Considerable above 1500m
Danger Level 3 - Considerable above 1500m
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-W-NW
Gliding snow above the treeline, E-SE-S-SW-W


The avalanche danger will decrease gradually. More small and, in isolated cases, medium-sized moist loose snow avalanches are possible.

The avalanches can in some places be released, mostly by large loads and reach medium size, in particular on wind-loaded slopes. On very steep grassy slopes more small and, in isolated cases, medium-sized gliding avalanches are possible. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.

Snowpack

dp 2: gliding snow

40 to 100 cm of snow, and even more in some localities, has fallen in the last few days above approximately 1500 m.
Over a wide area fresh snow and wind slabs are lying on soft layers, especially above the tree line. Dry and moist avalanches can be triggered in near-surface layers and reach medium size.
The snowpack remains moist at low and intermediate altitudes.

Tendency

The avalanche danger will decrease gradually.

Danger level
Danger Level 3 - Considerable
Avalanche Problem
Gliding snow above 2600m, N-NE-E-SE-S-SW-W-NW
Wind-drifted snow above the treeline, N-NE-E-W-NW


Gliding snow represents the main danger. This applies on steep grassy slopes. Fresh wind slabs require caution, in particular above the tree line.

On steep grassy slopes more gliding avalanches are possible, even quite large ones, in the regions exposed to heavier precipitation especially. This applies below approximately 2600 m.
The fresh wind slabs are in some cases still prone to triggering above the tree line. They can be released even by a single winter sport participant especially on very steep shady slopes. This applies in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example as well as adjacent to ridgelines. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Large avalanches are possible in isolated cases, especially in high Alpine regions.
Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger.

Snowpack

dp 2: gliding snow
dp 6: cold, loose snow and wind

Over a wide area 10 cm of snow, and even more in some localities, fell. The snowpack will be moist at low and intermediate altitudes. In some places wind slabs are lying on soft layers, especially at high altitudes and in high Alpine regions. The sometimes strong wind has transported a lot of snow. The fresh and somewhat older wind slabs are in many cases quite large.

Tendency

The danger of gliding avalanches will decrease gradually. The danger of slab avalanches will decrease.
