Wet snow represents the main danger. Weakly bonded old snow at elevated altitudes. Natural avalanches must be expected more frequently.
As a consequence of warming natural moist avalanches are to be expected, this applies already in the early morning. The avalanche prone locations are to be found in all aspects below approximately 2700 m. In isolated cases avalanches can also release deeper layers of the snowpack and reach large size, especially on very steep west, north and east facing slopes above approximately 2400 m. More small and, in isolated cases, medium-sized loose snow avalanches are possible. The danger of natural wet avalanches will increase during the day.
Weakly bonded old snow is to be evaluated critically, in particular on steep shady slopes at high altitudes and in high Alpine regions. Avalanches can in some cases be released easily and reach large size.
Snowpack
dp.10: springtime scenario dp.4: cold following warm / warm following cold
As a consequence of sharply rising temperatures and high relative humidity an unfavourable avalanche situation will develop by the early morning. The meteorological conditions will cause a gradual weakening of the near-surface layers. Faceted weak layers exist in the old snowpack on very steep west, north and east facing slopes, especially above approximately 2400 m. 10 to 30 cm of snow, and even more in some localities, has fallen since Thursday above approximately 2200 m. In some places new snow is lying on soft layers, in particular on shady slopes.
Tendency
The avalanche danger will persist. Wet snow requires caution.

Increase in danger of moist and wet avalanches as a consequence of warming. The wind slabs of the last few days are to be evaluated with care and prudence.
Increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation. In particular on steep sunny slopes avalanches can in many cases reach medium size. As a consequence of the solar radiation, the likelihood of slab avalanches being released will increase significantly in all aspects below approximately 2700 m. Backcountry tours and off-piste skiing should be concluded timely. The wind slabs of the last few days can be released by a single winter sport participant. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. In high Alpine regions the avalanche prone locations are more prevalent. The wind slabs are to be bypassed as far as possible. In very isolated cases weak layers exist in the old snowpack in particular on shady slopes. These avalanche prone locations are rather rare and are therefore difficult to recognise.
Snowpack
dp.10: springtime scenario
Over a wide area 15 to 30 cm of snow, and even more in some localities, has fallen since Thursday. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack in particular on steep sunny slopes. The sometimes new snow-covered wind slabs of the last few days remain for the foreseeable future prone to triggering at intermediate and high altitudes. In very isolated cases weak layers exist in the old snowpack in particular on shady slopes.
Tendency
Some snow will fall in some localities. The rain will give rise towards the evening to moistening of the snowpack in particular at intermediate altitudes.

As a consequence of warming wet snow slides and avalanches are to be expected, this applies already in the early morning. The avalanche prone locations are to be found in all aspects. The danger of wet avalanches will increase during the day. 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.

As a consequence of sharply rising temperatures and high relative humidity an unfavourable avalanche situation will develop by the early morning. The meteorological conditions will cause a weakening of the snowpack. At low and intermediate altitudes hardly any snow is lying.
Tendency
From a snow sport perspective, in most cases insufficient snow is lying.
