Even single freeriders can release avalanches very easily.
Outside marked and open pistes a dangerous avalanche situation will prevail.
Wind slabs remain prone to triggering on west, north and east facing slopes above the tree line, caution is to be exercised, including in areas close to the tree line. Avalanches can be released in near-surface layers of the snowpack. Additionally avalanches can also penetrate near-ground layers of the snowpack and reach large size on west, north and east facing slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible in isolated cases.
As a consequence of warming during the day and solar radiation moist loose snow avalanches are possible. This applies especially on very steep sunny slopes below approximately 2200 m.
Snowpack
dp.1: deep persistent weak layer dp.10: springtime scenario
The sometimes strong wind will transport the snow. Further wind slabs will form.
The snowpack will be prone to triggering over a wide area. The new snow and wind slabs are lying on top of a weakly bonded old snowpack. Somewhat older wind slabs are lying on surface hoar in some places. Distinct weak layers exist in the bottom section of the old snowpack. This applies in particular on west, north and east facing slopes above the tree line.
The weather conditions as the day progresses will give rise to moistening of the snowpack. This applies especially on very steep sunny slopes.
Tendency
Gradual decrease in avalanche danger.

The avalanche danger is within the uppermost range of danger level 3 (considerable).
Shady slopes: Weakly bonded old snow requires caution. Very steep sunny slopes: Increase in danger of wet avalanches as a consequence of warming.
Avalanches can be released in the old snowpack and reach large size in isolated cases on west, north and east facing slopes. This applies in case of a single winter sport participant. The avalanche prone locations are to be found in particular above the tree line. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances.
The wind has transported some snow. In particular adjacent to ridgelines and in gullies and bowls as well as at elevated altitudes sometimes avalanche prone wind slabs formed.
As a consequence of warming during the day and solar radiation small and medium-sized wet avalanches are possible. This applies in particular on very steep sunny slopes below approximately 2200 m. The runout zones are to be treated with caution.
Snowpack
dp.1: deep persistent weak layer dp.10: springtime scenario
Up to 20 cm of snow, and even more in some localities, fell in the last few days. The wind has transported some snow. Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. Outgoing longwave radiation during the night will be reduced. The weather conditions as the day progresses will give rise to gradual and thorough wetting of the snowpack. This applies on very steep sunny slopes below approximately 2200 m.
Tendency
The activity of wet avalanches will gradually increase.

Snowpack

Fresh wind slabs are to be evaluated critically. Weak layers in the old snowpack can be released in isolated cases.
Avalanches can in isolated cases be released in the old snowpack and reach medium size in isolated cases on west, north and east facing slopes. This applies in case of a single winter sport participant. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances.
