Lechtal Alps East

Fresh wind slabs at elevated altitudes. Slight increase in danger of wet avalanches.

Fresh wind slabs at elevated altitudes. Slight increase in danger of wet avalanches.

As a consequence of a sometimes strong southerly foehn wind, avalanche prone wind slabs will form in some cases. Such avalanche prone locations for dry avalanches are to be found on very steep shady slopes at elevated altitudes, in particular adjacent to ridgelines, as well as at the base of rock walls and behind abrupt changes in the terrain. In regions exposed to the foehn wind these avalanche prone locations are a little more prevalent. As a consequence of warming during the day, the likelihood of wet loose snow avalanches being released will increase. On very steep slopes individual mostly small wet loose snow avalanches are possible from late morning. An increasing number of small and, in isolated cases, medium-sized gliding avalanches are possible as the penetration by moisture increases.

As a consequence of a sometimes strong southerly foehn wind, small wind slabs will form in the regions exposed to the foehn wind. Faceted weak layers exist deeper in the old snowpack on little used shady slopes. As a consequence of mild temperatures and partly cloudy skies no crust will develop on the surface during the course of the night. Sunshine and high temperatures will give rise as the day progresses to increasing softening of the snowpack. Below the tree line only a little snow is now lying.

The wind will be strong over a wide area in particular in the regions exposed to the foehn wind. The foehn wind will transport only a little snow. Fresh wind slabs will form in particular in high Alpine regions. The surface of the snowpack will cool hardly at all during the overcast night. The weather conditions will give rise to increasing softening of the snowpack. This applies at intermediate and high altitudes.
