Border Pennine Alps

Old wind slabs will be covered with new snow in some cases and therefore difficult to recognise.

Old wind slabs will be covered with new snow in some cases and therefore difficult to recognise.

The older wind slabs can be released, even by a single winter sport participant or triggered naturally. The avalanche prone locations are to be found especially in gullies and bowls, and behind abrupt changes in the terrain and on steep slopes. At elevated altitudes these avalanche prone locations are more prevalent. Additionally avalanches can also be triggered in the old snowpack and reach large size. Careful route selection and spacing between individuals are recommended.

Thursday: The sometimes storm force wind has transported the new snow significantly. The various wind slabs are lying on soft layers in particular on shady slopes. Some snow fell yesterday. Intermediate and high altitudes: Large-grained weak layers exist in the bottom section of the snowpack in particular on shady slopes.
