Stability: poor · Frequency: some
The conditions are unfavourable. The new snow and wind slabs represent the main danger.
Weak layers exist in the old snowpack in particular on steep shady slopes. In addition the wind slabs also in gullies and bowls, and behind abrupt changes in the terrain are capable of being triggered still.
As a consequence of northeasterly wind, sometimes easily released wind slabs formed in the last few days in particular adjacent to ridgelines and in gullies and bowls. On steep shady slopes and in gullies and bowls, and behind abrupt changes in the terrain slab avalanches are possible, even large ones in isolated cases.
The snowpack will become in most cases subject to considerable local variations. In some cases the various wind slabs have bonded still only poorly with the old snowpack.
