Wind slabs and weakly bonded old snow in the high Alpine regions. As a consequence of warming during the day and the solar radiation, the likelihood of snow slides and avalanches being released will increase gradually.

Wind slabs and weakly bonded old snow in the high Alpine regions. As a consequence of warming during the day and the solar radiation, the likelihood of snow slides and avalanches being released will increase gradually.

Late morning: The fresh wind slabs are in individual cases still prone to triggering. These avalanche prone locations are to be found in particular on northwest to north to east facing aspects above approximately 2400 m, especially in gullies and bowls, and behind abrupt changes in the terrain. Weak layers in the old snowpack can be released in isolated cases by individual winter sport participants. The avalanche prone locations are to be found in particular on very steep northwest, north and east facing slopes above approximately 2200 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Midday and afternoon: As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little. In addition the danger of wet loose snow avalanches will increase. This applies on extremely steep slopes in all aspects below approximately 2400 m, in particular on very steep east, south and west facing slopes below approximately 2800 m. Backcountry tours, off-piste skiing and ascents to alpine cabins should be concluded timely.

The wind slabs of the last few days are in some cases prone to triggering on very steep shady slopes above approximately 2400 m. Faceted weak layers exist in the old snowpack, in particular on shady slopes above approximately 2200 m, as well as on east and west facing slopes above approximately 2400 m. The surface of the snowpack is frozen, but not to a significant depth and will soften quickly. Sunshine and high temperatures will give rise as the day progresses to a loss of strength within the snowpack. The conditions will bring about a weakening of the weak layers. The snowpack will become increasingly prone to triggering.

Tuesday: Wind and new snow. Fresh wind slabs require caution.
