Upper Passeier Valley

Fresh wind slabs require caution, especially in the regions exposed to heavier precipitation. Weakly bonded old snow requires caution.

Fresh wind slabs require caution, especially in the regions exposed to heavier precipitation. Weakly bonded old snow requires caution.

The fresh wind slabs can be released by a single winter sport participant in some cases in all aspects. Caution is to be exercised in gullies and bowls, and behind abrupt changes in the terrain, as well as adjacent to ridgelines above the tree line. At elevated altitudes the likelihood of avalanches being released is greater. Weak layers in the old snowpack can be released in some places. The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2000 m. On wind-loaded slopes medium-sized avalanches are possible. Meticulous route selection is advisable.

Over a wide area 5 to 15 cm of snow has fallen since Thursday. As a consequence of a moderate to strong wind from variable directions, further wind slabs formed especially adjacent to ridgelines and in gullies and bowls. The fresh wind slabs are lying on soft layers in particular on shady slopes. The older wind slabs are lying on surface hoar in some places. Avalanche prone weak layers exist in the old snowpack, especially on steep shady slopes above approximately 2000 m, as well as on steep sunny slopes in high Alpine regions. Only a small amount of snow is lying for the time of year.

The avalanche danger will persist. Wind slabs and weakly bonded old snow represent the main danger.
