Vicentine Prealps

Fresh wind slabs require caution. Weak layers in the old snowpack can be released. The danger of moist and wet avalanches will increase during the day. In the event of solar radiation this applies in particular in the Prealps.

The fresh wind slabs can be released by a single winter sport participant and reach large size in isolated cases. Avalanche prone locations are to be found in particular on steep shady slopes above the tree line. Caution is to be exercised in particular adjacent to ridgelines, as well as in gullies and bowls, and behind abrupt changes in the terrain. The avalanche prone locations are sometimes covered with new snow and are difficult to recognise. Additionally in some places avalanches can release deeper layers of the snowpack. Such avalanche prone locations are to be found on steep west, north and east facing slopes and in little used terrain. In isolated cases avalanches are large. In the regions exposed to heavier precipitation the avalanche prone locations are more prevalent. Whumpfing sounds can indicate the danger. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Restraint should be exercised because avalanches can sweep people along and give rise to falls. As a consequence of warming during the day and solar radiation moist loose snow avalanches are to be expected as the day progresses, even medium-sized ones.

The fresh wind slabs are lying on soft layers in particular on steep shady slopes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Sunshine and high temperatures will give rise as the day progresses to moistening of the snowpack on steep sunny slopes.
