Lechtal Alps East

Wind slabs and weakly bonded old snow are to be assessed with care and prudence.

Wind slabs and weakly bonded old snow are to be assessed with care and prudence.

As a consequence of the moderate to strong foehn wind, the snow drift accumulations will increase in size. The fresh and older wind slabs are prone to triggering. These can be released in the weakly bonded old snow, even by a single winter sport participant. Avalanches can reach medium size. The avalanche prone locations are to be found in particular on west to north to east facing aspects above approximately 2200 m. Caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain, as well as on wind-loaded slopes. The avalanche prone locations are barely recognisable.

As a consequence of a freshening southwesterly wind, further wind slabs will form. The fresh and older wind slabs are lying on top of a weakly bonded old snowpack. They are bonding only slowly with the old snowpack. The old snowpack consists of faceted crystals. The snowpack will be generally subject to considerable local variations. Only a small amount of snow is lying for the time of year in all altitude zones.

Hardly any decrease in danger.
