Fresh wind slabs represent the main danger. Gliding snow requires caution.
The fresh wind slabs are very prone to triggering in all aspects. Caution is to be exercised in particular above approximately 2200 m, as well as in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can be released easily and reach quite a large size. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. There is a danger of gliding avalanches. This applies on steep grassy slopes below approximately 2400 m. Areas with glide cracks are to be avoided. Weak layers in the old snowpack can be released especially by large additional loads in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. This applies on very steep slopes above approximately 2200 m. Avalanches can reach large size in isolated cases.
The weather conditions gave rise to increasing moistening of the snowpack below approximately 2200 m. Over a wide area 10 to 25 cm of snow will fall. As a consequence of new snow and a strong to storm force northwesterly wind, further wind slabs will form. These are lying on soft layers in all aspects at high altitudes and in high Alpine regions. Faceted weak layers exist in the centre of the snowpack in particular above approximately 2200 m.
The avalanche danger will persist.
