Increase in danger of moist avalanches as a consequence of warming during the day and solar radiation. The avalanche conditions in the morning below approximately 2300 m are generally favourable.

Numerous moist avalanches have been released as a consequence of the precipitation. In all regions there will be an appreciable decrease in the avalanche danger during the course of the night.
Late morning: Fresh and older wind slabs represent the main danger. These can be released by a single winter sport participant in particular on northwest to north to southeast facing aspects at high altitudes and in high Alpine regions. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. In addition a moderate (level 2) danger of gliding avalanches exists, especially below approximately 2300 m on steep grassy slopes.
Midday and afternoon: As the day progresses as a consequence of warming during the day and solar radiation there will be a rapid increase in the danger of moist and wet avalanches. More frequent small and medium-sized moist loose snow avalanches are to be expected. This applies on extremely steep sunny slopes. More frequent small and medium-sized gliding avalanches are to be expected. This applies on steep grassy slopes in all aspects below approximately 2300 m. This also applies on steep sunny slopes below approximately 2600 m. As the day progresses the likelihood of slab avalanches being released will increase a little at high altitudes and in high Alpine regions.

Snowpack

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

Outgoing longwave radiation during the night will be good over a wide area. The surface of the snowpack will freeze to form a strong crust only at high altitudes and will soften during the day. The old snowpack will be wet all the way through at low and intermediate altitudes. In some places fresh snow and wind slabs are lying on soft layers. This applies in particular above approximately 2300 m. In very isolated cases weak layers exist in the old snowpack in particular on west, north and northeast facing slopes, especially above approximately 2500 m.

Tendency

Decrease in avalanche danger as the temperature drops.

Increase in danger of moist avalanches as a consequence of warming during the day and solar radiation. The avalanche conditions in the morning below approximately 2300 m are generally favourable.

Early morning: Fresh and older wind slabs represent the main danger. These can be released in isolated cases, but mostly only by large additional loads, in particular on northwest to north to southeast facing aspects above approximately 2300 m. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.
