Wind slab
- Above 2,300 m
Above approximately 2300 m the avalanche prone locations are more prevalent. Fresh wind slabs are to be evaluated with care and prudence.
Above approximately 2300 m the avalanche prone locations are more prevalent. Fresh wind slabs are to be evaluated with care and prudence.
As a consequence of a moderate to strong wind from northwesterly directions, wind slabs will form above the tree line. The more recent wind slabs are bonding only slowly with the old snowpack. These can be released by a single winter sport participant in some cases. These avalanche prone locations are to be found in particular on very steep slopes and in gullies and bowls, and behind abrupt changes in the terrain. The avalanche prone locations are easy to recognise. Ski touring and other off-piste activities, including snowshoe hiking, call for a certain restraint. Individual snow slides are possible as the day progresses, especially on extremely steep slopes at the base of rock walls.
20 to 40 cm of snow fell on Monday in all altitude zones. The areas bordering France are most affected. The covering of new snow is soft. Towards its surface, the snowpack is largely stable and has a loosely bonded surface,, also above approximately 2300 m. Towards its base, the snowpack is well consolidated.
Friday: Down to low altitudes snow will fall. The danger will increase during the day. The wind slabs will be covered with new snow in some cases and therefore difficult to recognise.
