Samnaun Mountains

Moderate danger of wet avalanches will prevail. Weak layers in the old snowpack can be released in some places at elevated altitudes.

Moderate danger of wet avalanches will prevail. Weak layers in the old snowpack can be released in some places at elevated altitudes.

As the penetration by moisture increases more small and medium-sized wet snow slides and avalanches are possible below approximately 2500 m. This applies in all aspects. In addition a certain danger of gliding avalanches exists. This applies in particular on steep grassy slopes in the regions with a lot of snow. As a consequence of the moist air the avalanche prone locations will become more prevalent as the day progresses. Dry avalanches can in some places be released, even by a single winter sport participant and reach dangerously large size. The avalanche prone locations for dry avalanches are to be found in particular on steep west, north and east facing slopes above approximately 2600 m. In particular bases of rock walls are especially unfavourable. These avalanche prone locations are barely recognisable, even to the trained eye.

The surface of the snowpack will cool hardly at all during the overcast night. The rain will give rise from the second half of the night to increasing and thorough wetting of the snowpack. This applies in particular in the High Tauern and in the Wetterstein Range. The high humditiy will give rise as the day progresses to gradual moistening of the snowpack also on shady slopes below approximately 2500 m. The snowpack will be weakly bonded below approximately 2500 m. Avalanche prone weak layers exist in the top section of the snowpack at high altitudes and in high Alpine regions. This applies in particular on steep west, north and east facing slopes above approximately 2600 m. Towards its base, the snowpack is well consolidated. At low and intermediate altitudes only a little snow is now lying.

Decrease in danger of wet avalanches as the temperature drops.
