Prealps

The older wind slabs represent the main danger.

The older wind slabs represent the main danger.

The wind slabs are poorly bonded with the old snowpack above approximately 1500 m. These are to be found in particular adjacent to ridgelines and in gullies and bowls in all aspects. The new snow and wind slabs of last week can be released by a single winter sport participant. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack. In particular above the tree line the avalanche prone locations are more prevalent. Apart from the danger of being buried, restraint should be exercised in view of the danger of avalanches sweeping people along and giving rise to falls.

Over a wide area 2 to 5 cm of snow, and even more in some localities, will fall until midday above approximately 1000 m. Until Sunday the weather will be cold over a wide area. As a consequence of low temperatures the snowpack will become faceted and therefore lose strength. The snowpack will become in some cases prone to triggering. In some cases the various wind slabs have bonded poorly with the old snowpack.

The avalanche danger will persist.
