Samnaun Mountains

Wind slabs and gliding snow require caution.

Wind slabs and gliding snow require caution.

As a consequence of new snow and a sometimes strong wind from northwesterly directions, sometimes avalanche prone wind slabs formed. Avalanches can in some places be released by a single winter sport participant and reach medium size. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain above approximately 2200 m. At elevated altitudes the avalanche prone locations are a little more prevalent. More gliding avalanches are possible, even quite large ones, in particular on steep grassy slopes below approximately 2600 m. Areas with glide cracks are to be avoided. On extremely steep slopes small to medium-sized loose snow avalanches are to be expected as a consequence of warming during the day and solar radiation.

10 to 15 cm of snow, and up to 20 cm in some localities, has fallen. Some snow will fall on Friday. Up to intermediate altitudes rain will fall. The northwesterly wind will transport the new snow. Avalanche prone weak layers exist in the top section of the snowpack. The fresh wind slabs are lying on unfavourable layers at elevated altitudes. Towards its base, the snowpack is largely stable. The high temperatures will give rise to significant moistening of the snowpack.

Wind slabs represent the main danger.
