Lechtal Alps East

New snow and wind slabs represent the main danger. Weakly bonded old snow above approximately 2400 m.

New snow and wind slabs represent the main danger. Weakly bonded old snow above approximately 2400 m.

As a consequence of snowfall and the strong to storm force westerly wind, the snow drift accumulations will increase in size. The large quantity of fresh snow of the weekend as well as the wind slabs to be found in all aspects can be released by a single winter sport participant above the tree line. Also slopes close to the tree line are unfavourable. Additionally avalanches can also be triggered in the old snowpack and reach large size, especially on steep shady slopes above approximately 2400 m, as well as on steep sunny slopes above approximately 2800 m. Experience in the assessment of avalanche danger is required.

Over a wide area 20 to 40 cm of snow will fall. Snow depths vary greatly above the tree line, depending on the infuence of the wind. The new snow and wind slabs are prone to triggering above the tree line. The snowpack will be unfavourable in areas close to 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 shady slopes above approximately 2400 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.

The weather conditions will bring about a gradual stabilisation of the snow drift accumulations.
