Lechtal Alps Central

As a consequence of new snow and strong wind there will be a gradual increase in the avalanche danger.

As a consequence of new snow and strong wind there will be a gradual increase in the avalanche danger.

The fresh snow as well as the wind slabs that are being formed by the strong to storm force northwesterly wind represent the main danger. The new snow and wind slabs can be released by a single winter sport participant in all aspects above the tree line. Distinct weak layers in the old snowpack can be released especially by large additional loads in particular on west, north and east facing slopes. This applies in particular in particular between approximately 2200 and 2600 m. Such avalanche prone locations are covered with new snow and are therefore barely recognisable. Avalanches can reach large size especially in shady places that are protected from the wind. As a consequence of the new snow there will be an increase in the danger of gliding avalanches, in the regions exposed to a lot of precipitation especially on steep grassy slopes.

In particular from the Silvretta via the Western Lechtal Alps to the Allgäu Alps 20 to 40 cm of snow, and even more in some localities, will fall. In the other regions 15 to 30 cm of snow will fall. The wind will be strong to storm force over a wide area. As a consequence of new snow and northwesterly wind, wind slabs will form in the course of the day in all aspects. The fresh wind slabs are bonding poorly with the old snowpack in particular on wind-protected shady slopes. They are prone to triggering. Older wind slabs have bonded quite well with the old snowpack. In its middle, the snowpack is faceted and weak. This applies on shady slopes above approximately 2200 m.

Further increase in avalanche danger as the snowfall becomes more intense.
