Avalanche Activity

Increase in danger of wet avalanches in the course of the day. Wind slabs are in individual cases still prone to triggering in high Alpine regions.

Early and late morning: The more recent wind slabs are now only very rarely prone to triggering. Individual avalanche prone locations are to be found in particular on very steep shady slopes in high Alpine regions. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls. During the day: As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase gradually. More frequent small to medium-sized wet loose snow avalanches are possible below approximately 2800 m, this also applies on extremely steep sunny slopes in high Alpine regions. In very isolated cases avalanches can release the saturated snowpack and reach a dangerous size. In addition further individual gliding avalanches are possible. This applies on steep grassy slopes below approximately 2600 m. Areas with glide cracks are to be avoided. Backcountry tours, off-piste skiing and ascents to alpine cabins should be started early and concluded timely.

Snowpack Structure

The surface of the snowpack has frozen to form a strong crust and will soften during the day. The high temperatures as the day progresses will give rise to increasing softening of the snowpack in all aspects below approximately 2800 m, this also applies on sunny slopes in high Alpine regions. As a consequence of a strong wind from southerly directions, wind slabs formed in the last few days in high Alpine regions. The weather effects brought about a substantial stabilisation of the snow drift accumulations.

Tendency

The danger of wet avalanches will increase during the day.
