As the day progresses as a consequence of new snow and strong wind there will be an increase in the avalanche danger.
As the day progresses as a consequence of new snow and strong wind there will be an increase in the avalanche danger.
As a consequence of new snow and a strong wind, avalanche prone wind slabs will form in the course of the day in particular above the tree line. Even single skiers can release avalanches with increasing likelihood, including medium-sized ones. The avalanche prone locations are to be found on steep shady slopes and in gullies and bowls, and behind abrupt changes in the terrain, in the regions exposed to heavier precipitation in particular in places that are protected from the wind. Additionally in very isolated cases avalanches can also be released in the old snowpack. Caution is to be exercised in areas where the snow cover is rather shallow.
At elevated altitudes snow depths vary greatly, depending on the infuence of the wind. The old snowpack will be subject to considerable local variations. The wind will be strong to storm force over a wide area. In some localities up to 20 cm of snow will fall. The wind will transport the fresh and old snow. The fresh snow and the wind slabs to be found especially adjacent to riddgelines are lying on soft layers on steep shady slopes above the tree line, in particular in places that are protected from the wind. In very isolated cases weak layers exist in the centre of the snowpack. This applies in particular on very steep shady slopes above approximately 2400 m. At low and intermediate altitudes less snow than usual is lying.
Hardly any decrease in avalanche danger.
