Graie Alps

The wind will be strong. Fresh and older wind slabs require caution.

The wind will be strong. Fresh and older wind slabs require caution.

The wind will be strong to storm force in the regions exposed to the foehn wind. In some localities a little new snow. In particular in gullies and bowls and behind abrupt changes in the terrain sometimes easily released wind slabs will form. Even single skiers can release avalanches in some places. The fresh wind slabs are mostly small but to be assessed critically. In addition hard wind slabs formed in particular adjacent to ridgelines and in the high Alpine regions. These can especially at their margins be released, in particular by large loads and reach large size in isolated cases.

The northwesterly wind will transport the old snow. Fresh and older wind slabs are lying on the unfavourable surface of an old snowpack above the tree line. Individual weak layers exist in the old snowpack on steep shady slopes. The old snowpack remains subject to considerable local variations at high altitudes and in high Alpine regions.

Increase in avalanche danger as a consequence of new snow and strong wind. This applies especially in the regions exposed to the foehn wind.
