Fresh wind slabs require caution.
As a consequence of new snow and a strong wind from northwesterly directions, extensive wind slabs formed above the tree line. In the course of the day the wind slabs will increase in size additionally. Even single winter sport participants can release avalanches in some places, including medium-sized ones. Avalanche prone locations are to be found on wind-loaded slopes and adjacent to ridgelines and in gullies and bowls. At elevated altitudes the likelihood of avalanches being released is greater. More gliding avalanches are possible, in particular medium-sized ones. This applies in particular on steep grassy slopes below approximately 2600 m. Areas with glide cracks are to be avoided. On extremely steep slopes small and, in isolated cases, medium-sized wet loose snow avalanches are to be expected as a consequence of warming during the day and solar radiation.
15 to 30 cm of snow, and up to 40 cm in some localities, has fallen. 5 to 10 cm of snow, and even more in some localities, will fall on Friday. Up to intermediate altitudes rain will fall in some regions. The northwesterly wind will transport the new snow. Avalanche prone weak layers exist in the top section of the snowpack. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack. Towards its base, the snowpack is largely stable. Low and intermediate altitudes: The high temperatures will give rise to significant moistening of the snowpack.
Wind slabs and gliding snow represent the main danger.
