Avalanche Problem

Wind slabs and wet snow require caution.

Wind slabs are to be assessed with care and prudence. The avalanche prone locations are sometimes covered with new snow and are difficult to recognise. Additionally in some places avalanches can also penetrate deep layers and reach large size. Increase in danger of wet avalanches in the course of the day, in the event of prolonged bright spells in particular.

Snowpack

dp.10: springtime scenario
dp.6: cold, loose snow and wind

Over a wide area 10 to 30 cm of snow, and even more in some localities, has fallen since Monday above approximately 2200 m. As a consequence of new snow and a moderate to strong northwesterly wind, wind slabs formed.
Avalanche prone weak layers exist in the top section of the snowpack in particular on steep shady slopes.
Sunshine and high temperatures will give rise as the day progresses to moistening of the snowpack.

Tendency

The meteorological conditions will facilitate a gradual stabilisation of the snowpack.

Danger level

Wind slabs at elevated altitudes. Wet avalanches as the day progresses.

The older wind slabs are to be evaluated with care and prudence in particular in very steep terrain, in particular on very steep shady slopes at high altitude. 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.
Increase in danger of wet snow slides as a consequence of warming during the day and solar radiation.

Snowpack

dp.6: cold, loose snow and wind
dp.10: springtime scenario

The mostly small wind slabs are in individual cases still prone to triggering, especially at high altitude.
The spring-like weather conditions will give rise to rapid moistening of the snowpack in particular on sunny slopes. At low and intermediate altitudes hardly any snow is lying.

Tendency

On Friday it will be mild. Increase in danger of wet avalanches in the course of the day.
