Avalanche Activity
Wind slabs and wet snow represent the main danger.
Since Tuesday the wind has been moderate to strong at times. As a consequence of a strong foehn wind, further wind slabs formed. Even single persons can release avalanches, including medium-sized ones, especially on very steep shady slopes. On wind-loaded slopes and in gullies and bowls, and behind abrupt changes in the terrain the likelihood of avalanches is higher. The surface of the snowpack will freeze very little and will already be soft in the early morning. Already in the early morning, individual gliding avalanches are possible.
Snowpack Structure
Only a small amount of snow is lying for the time of year. The storm force wind has transported the new snow significantly. The fresh wind slabs are poorly bonded with the old snowpack in particular on shady slopes and generally at elevated altitudes. The old snowpack consists of faceted crystals, in particular on shady slopes.
Tendency
Wind slabs are to be evaluated with care and prudence.
