Lechtal Alps East

Wind slabs and weakly bonded old snow require caution.

Wind slabs and weakly bonded old snow require caution.

The fresh and older wind slabs remain prone to triggering. Avalanche prone locations are to be found above the tree line and in areas close to the tree line. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Avalanches are medium-sized. Additionally avalanches can also be triggered in the old snowpack, especially on very steep slopes above approximately 2200 m. Experience in the assessment of avalanche danger is required. On steep grassy slopes more small and, in isolated cases, medium-sized gliding avalanches are possible. This applies in particular in the regions with a lot of snow.

Some snow will fall in some regions. The snowpack will be subject to considerable local variations. Snow depths vary greatly above the tree line, depending on the infuence of the wind. The new snow and wind slabs remain prone to triggering above the tree line. Faceted weak layers exist in the centre of the snowpack. This applies in particular above approximately 2200 m. Shooting cracks when stepping on the snowpack and whumpfing sounds confirm the unfavourable bonding of the snowpack.

Over a wide area 15 to 30 cm of snow, and even more in some localities, will fall on Friday. As a consequence of new snow and strong wind there will be an increase in the avalanche danger. Wind slabs and weakly bonded old snow require caution.
