Cervinia and Upper Valpelline Valley

Weak layers in the old snowpack are treacherous. In particular, however, the fresh and older wind slabs must be taken into account.

Weak layers in the old snowpack are treacherous. In particular, however, the fresh and older wind slabs must be taken into account.

As a consequence of a moderate to strong wind from northerly directions, avalanche prone wind slabs will form in gullies and bowls and behind abrupt changes in the terrain. Single winter sport participants can release avalanches. In particular along the border with Switzerland the avalanche prone locations are more widespread and the danger is greater. The new snow and wind slabs of last week are lying on the unfavourable surface of an old snowpack on northwest to north to east facing aspects. Especially on very steep slopes they can be triggered in the faceted old snow. The avalanche prone locations are to be found in particular in little used terrain. Remotely triggered avalanches are possible.

The wind will be moderate to strong in particular along the border with Switzerland. Wind slabs will form. Several small and medium-sized dry slab avalanches have been released by people in the last few days. The new snow and wind slabs of last week are bonding only slowly with the old snowpack in particular on shady slopes. Large-grained weak layers exist in the old snowpack here. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. The numerous rocks hidden by the recent snow are the main danger.

The weather will be sunny. The wind will be moderate to strong in particular along the border with Switzerland. The wind slabs remain prone to triggering.
