Points saillants

The weather will be very mild. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase in all aspects above the tree line. Wind slabs require caution. In all aspects slab avalanches are possible.

Avalanche Activity

The weather will be very mild. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase in all aspects above the tree line. Wind slabs require caution. In all aspects slab avalanches are possible.

Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. The wind slabs can be released even by a single winter sport participant above the tree line, caution is to be exercised in particular at the base of rock walls and behind abrupt changes in the terrain, as well as adjacent to ridgelines and in gullies and bowls. Additionally in isolated cases avalanches can penetrate near-ground layers of the snowpack and reach large size in isolated cases, especially on west, north and east facing slopes above approximately 2000 m. The danger of moist and wet avalanches will already increase in the late morning. As a consequence of warming during the day and solar radiation the prevalence of the avalanche prone locations will increase from midday. In particular very steep sunny slopes, intermediate and high altitudes: In steep terrain there is a danger of falling on the icy crust.

Snowpack Structure

These spring-like weather conditions as the day progresses will give rise to moistening of the snowpack below approximately 2500 m. As a consequence of wind from northerly directions, avalanche prone wind slabs formed in the last few days in particular in gullies and bowls and behind abrupt changes in the terrain, especially in all aspects above approximately 2000 m at elevated altitudes. The old snowpack will be weakly bonded in some places. In some cases the various wind slabs have bonded still only poorly together.

Tendency

Wind slabs and weakly bonded old snow are to be assessed with care and prudence.
