Avalanche Activity

Gliding snow requires caution. Wind slabs and weakly bonded old snow require caution.

A substantial danger of gliding avalanches exists. This applies on steep grassy slopes below approximately 2400 m. Areas with glide cracks are to be avoided. The fresh wind slabs are prone to triggering in all aspects. Caution is to be exercised in particular on wind-loaded slopes above approximately 2200 m, as well as in gullies and bowls, and behind abrupt changes in the terrain. 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.

Snowpack Structure

The weather conditions gave rise to moistening of the snowpack below approximately 2200 m. Over a wide area 15 to 40 cm of snow will fall. As a consequence of new snow and a strong to storm force westerly wind, extensive wind slabs will form. The fresh wind slabs 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.

Tendency

The avalanche danger will persist.
