Upper Passeier Valley

Avalanches can be released in the weakly bonded old snow in isolated cases. Fresh wind slabs require caution.

As a consequence of new snow and a sometimes strong wind from northerly directions, further wind slabs will form on Sunday. The avalanche prone locations are quite prevalent and are barely recognisable because of the poor visibility. Avalanches can additionally in isolated cases be released in deeper layers. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls.

Avalanches can be released in the weakly bonded old snow in isolated cases. Fresh wind slabs require caution.

In isolated cases avalanches can be released in the old snowpack and reach medium size, in particular on very steep northwest, north and east facing slopes above approximately 2400 m. Especially slopes adjacent to ridgelines are unfavourable. The prevalence of the avalanche prone locations will increase in the high Alpine regions. They are difficult to recognise. As a consequence of a moderate southerly wind, mostly small wind slabs formed since Friday in isolated cases. These are prone to triggering. The avalanche prone locations are to be found in particular adjacent to ridgelines and in pass areas. The prevalence of the avalanche prone locations will increase with altitude. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.

The snowpack is weak in some cases; its surface is loosely bonded and consists of surface hoar and faceted crystals. Faceted weak layers exist in the centre of the old snowpack, especially on northwest, north and northeast facing slopes at high altitudes and in high Alpine regions. As a consequence of a moderate wind from southerly directions, mostly shallow wind slabs formed since Friday especially adjacent to ridgelines and in pass areas. The fresh wind slabs are lying on unfavourable layers. In all altitude zones only a little snow is lying.
