New snow and wind slabs above approximately 2300 m.

New snow and wind slabs above approximately 2300 m.

The new snow and wind slabs are lying on the unfavourable surface of an old snowpack in particular on very steep shady slopes above approximately 2300 m. The fresh wind slabs are to be found in particular adjacent to ridgelines and in gullies and bowls and generally at high altitudes, caution is to be exercised at transitions from a shallow to a deep snowpack. In particular along the border with France the avalanche prone locations are a little 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.

10 to 25 cm of snow has fallen since Monday above approximately 1300 m. In some cases the wind slabs have bonded poorly with the old snowpack. Over a wide area new snow is lying on a hard crust. In high Alpine regions snow depths vary greatly, depending on the infuence of the wind. Below approximately 2000 m from a snow sport perspective, in most cases insufficient snow is lying.

Slight increase in avalanche danger as a consequence of new snow and wind.
