Weak layers in the upper part of the snowpack necessitate caution. Increase in danger of wet and gliding avalanches in the course of the day.
Weak layers in the upper part of the snowpack can be released in isolated cases by winter sport participants. Caution is to be exercised in particular on very steep slopes above approximately 2200 m. Especially shady slopes are unfavourable. Mostly avalanches are medium-sized. The avalanche prone locations are difficult to recognise. As the day progresses as a consequence of warming during the day and solar radiation there will be a gradual increase in the danger of wet and gliding avalanches. Especially on rocky east, south and west facing slopes small to medium-sized wet avalanches are to be expected as the penetration by moisture increases. In addition further gliding avalanches are possible. This applies on steep grassy slopes below approximately 2600 m. Areas with glide cracks are to be avoided.
At the interface between the old snow surface and the new snow of the past week, occasionally a faceted weak layer developed. This applies above approximately 2200 m. Sunshine and high temperatures will give rise as the day progresses to gradual softening of the snowpack especially on sunny slopes. The old snowpack will be stable.
Weak layers in the upper part of the snowpack necessitate caution. Wet loose snow avalanches and gliding avalanches are still possible.
