Valgrisenche

Wind slabs represent the main danger.

Wind slabs represent the main danger.

Wind slabs can sometimes be released by a single winter sport participant. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain above approximately 2000 m and in places that are protected from the wind. Especially at intermediate and high altitudes these avalanche prone locations are more widespread. The more recent wind slabs are in many cases extensive. They are quite prevalent and are clearly recognisable to the trained eye, caution is to be exercised on very steep slopes at transitions from a shallow to a deep snowpack. Backcountry touring and other off-piste activities call for restraint.

The strong wind has transported the new snow. The weather conditions gave rise to unfavourable bonding of the snowpack in some places. In some places new snow and wind slabs are lying on a weakly bonded old snowpack. The snowpack will be generally subject to considerable local variations. In all aspects snow depths vary greatly above approximately 2000 m, depending on the infuence of the wind. Adjacent to ridgelines and in pass areas and at high altitudes and in high Alpine regions a little snow is lying.

The avalanche danger will persist.
