Border Pennine Alps

Gradual increase in avalanche danger as a consequence of new snow and strong wind. This applies in particular in the regions exposed to heavier precipitation.

Gradual increase in avalanche danger as a consequence of new snow and strong wind. This applies in particular in the regions exposed to heavier precipitation.

As a consequence of new snow and a strong wind from northwesterly directions, wind slabs will form over a wide area. This applies in particular in gullies and bowls, and behind abrupt changes in the terrain especially above the tree line. New snow and wind slabs can be released, even by a single winter sport participant and reach large size. Additionally avalanches can also be released in deep layers and reach very large size in isolated cases in particular on shady slopes. The avalanche prone locations are barely recognisable because of the poor visibility. Meticulous route selection is required. Maintaining distances between individuals and one-at-a-time descents are recommended.

10 to 20 cm of snow fell on Wednesday above approximately 1500 m. Over a wide area 15 to 30 cm of snow will fall on Thursday above approximately 1800 m. As a consequence of new snow and a moderate to strong wind from northwesterly directions, further wind slabs formed in particular above the tree line. The new snow and wind slabs are lying on soft layers on wind-protected shady slopes. Intermediate and high altitudes: Large-grained weak layers exist in the bottom section of the snowpack in particular on shady slopes. High altitudes and the high Alpine regions: The sometimes strong wind has transported the fresh and old snow significantly.

The avalanche danger will not decrease for the time being. Along the border between Valais and Italy and on wind-loaded slopes the likelihood of avalanches is high.
