Weakly bonded old snow represents the main danger. Fresh wind slabs are to be evaluated with care and prudence.

In some places avalanches can be triggered in the weakly bonded old snow and reach large size in isolated cases, in particular on very steep shady slopes above approximately 2400 m.
In addition the wind slabs are easily triggered still. They are to be evaluated with care and prudence in particular on very steep shady slopes above approximately 2400 m. Avalanches can penetrate deep layers.

Slight increase in danger of wet avalanches in the course of the day, in the event of prolonged bright spells in particular.

Snowpack

dp.4: cold following warm / warm following cold
dp.6: cold, loose snow and wind

Over a wide area 15 to 30 cm of snow, and even more in some localities, has fallen since Sunday. As a consequence of new snow and a moderate to strong northwesterly wind, sometimes large wind slabs formed. These are lying on soft layers in particular on shady slopes above approximately 2400 m. The wind will be moderate to strong for a temporary period in particular in the regions exposed to the foehn wind.
Avalanche prone weak layers exist in the top section of the snowpack in particular on steep shady slopes.

Tendency

The meteorological conditions will facilitate a slow stabilisation of the snowpack. Wet avalanches as the day progresses.

Weakly bonded old snow is to be evaluated with care and prudence. Wind slabs require caution.

Weak layers in the old snowpack can be released in some places even by individual winter sport participants in particular on very steep shady slopes, especially above approximately 2400 m.

Wind slabs are rather small but can be released in isolated cases. Additionally in some places avalanches can also penetrate deep layers and reach large size, in particular on very steep shady slopes above approximately 2400 m.

Slight increase in danger of wet avalanches in the course of the day, in the event of prolonged bright spells in particular.

Snowpack

dp.4: cold following warm / warm following cold
dp.6: cold, loose snow and wind

In some localities up to 10 cm of snow will fall on Tuesday. As a consequence of new snow and a moderate to strong northwesterly wind, small wind slabs will form.
Avalanche prone weak layers exist in the top section of the snowpack in particular on steep shady slopes.

The weather conditions as the day progresses will give rise to increasing moistening of the snowpack, in the event of prolonged bright spells in particular.

Tendency

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


Danger level



Wind slabs at elevated altitudes.

The fresh 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.
Slight 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

Some snow has fallen since Sunday in some regions, 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

Low avalanche danger will prevail. From a snow sport perspective, in most cases insufficient snow is lying.
