Lechtal Alps East

The fresh wind slabs represent the main danger. Weakly bonded old snow above approximately 2200 m.

The fresh wind slabs represent the main danger. Weakly bonded old snow above approximately 2200 m.

As a consequence of a strengthening northeasterly wind, avalanche prone wind slabs will form in some places. The fresh wind slabs can be released even by a single winter sport participant. Avalanches can reach medium size. The avalanche prone locations are to be found in all aspects above the tree line, in particular adjacent to ridgelines and in pass areas, as well as in gullies and bowls, and behind abrupt changes in the terrain. Additionally avalanches can also be released in the old snowpack. These avalanche prone locations are to be found on steep, little used shady slopes above approximately 2200 m and on steep sunny slopes above approximately 2500 m. The number and size of avalanche prone locations will increase with altitude. Meticulous route selection is advisable.

In some localities up to 10 cm of snow will fall on Saturday. As a consequence of a strengthening wind from northeasterly directions, further wind slabs will form in the course of the day. The new snow and wind slabs of the last few days are poorly bonded with the old snowpack in some places. These are mostly small but in some cases prone to triggering. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2500 m. Field observations show that the stability of the snowpack varies greatly within a small area.

Sunday: Over a wide area some new snow. In some regions moderate northeasterly wind. The avalanche danger will persist.
