Lechtal Alps East

Wind slabs and weakly bonded old snow require caution.

Wind slabs and weakly bonded old snow require caution.

The wind slabs of the last few days remain prone to triggering. Avalanche prone locations are to be found in particular on very steep slopes above the tree line. This also applies adjacent to ridgelines and in gullies and bowls above the tree line. The wind slabs can be released by a single winter sport participant in all aspects. Avalanches are medium-sized. Additionally avalanches can also be triggered in the old snowpack and reach large size, especially on steep shady slopes above approximately 2200 m, as well as on steep sunny slopes above approximately 2800 m. Experience in the assessment of avalanche danger is required.

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. The new snow and wind slabs will be deposited on soft layers on wind-protected shady slopes at elevated altitudes. Faceted weak layers exist in the centre of the snowpack. This applies in particular on steep west, north and east facing slopes above approximately 2200 m, as well as on steep sunny slopes above approximately 2800 m. Shooting cracks when stepping on the snowpack and whumpfing sounds confirm the unfavourable bonding of the snowpack.

Slight increase in avalanche danger as a consequence of new snow and wind.
