In sintesi

Avalanche Activity

Weakly bonded old snow represents the main danger, especially above approximately 2400 m. Old wind slabs require caution. Gliding snow requires caution.

Weak layers in the upper part of the snowpack can be released by individual winter sport participants. Avalanche prone locations are to be found in particular on steep shady slopes above approximately 2400 m. Places where surface hoar has been covered with snow are especially unfavourable. Avalanches can reach large size in isolated cases. Careful route selection is recommended. As a consequence of a sometimes strong southerly wind, sometimes avalanche prone wind slabs will form. Caution is to be exercised in particular on very steep shady slopes, as well as adjacent to ridgelines and in pass areas at elevated altitudes. The prevalence of such avalanche prone locations will increase with altitude. In addition a latent danger of gliding avalanches exists, in particular on steep east, south and west facing slopes below approximately 2600 m. Areas with glide cracks are to be avoided as far as possible.

Snowpack Structure

Faceted weak layers exist in the top section of the old snowpack in particular on west, north and east facing slopes. This applies above approximately 2400 m. In some places new snow is lying on surface hoar. Fresh wind slabs are lying on soft layers at elevated altitudes. Outgoing longwave radiation during the night will be severely restricted. The surface of the snowpack will freeze to form a strong crust only at high altitudes.

Tendency

Some snow will fall in some localities. The avalanche danger will persist.
