Rhemes Valley

Outgoing longwave radiation during the night will be reduced in some case. The danger of moist and wet avalanches will already increase in the late morning.

Outgoing longwave radiation during the night will be reduced in some case. The danger of moist and wet avalanches will already increase in the late morning.

The surface of the snowpack will only just freeze. The high humditiy will give rise in the afternoon to moistening of the snowpack in all aspects below approximately 2800 m. These meteorological conditions will cause a rise in the danger of wet and gliding avalanches below approximately 2800 m. They can be released naturally, caution is to be exercised in particular in starting zones that still retain some snow. In addition the wind slabs especially in high Alpine regions are capable of being triggered in isolated cases. Single snow sport participants can release avalanches in isolated cases. This applies in particular on very steep slopes adjacent to ridgelines.

The weather will be cloudy. Outgoing longwave radiation during the night will be reduced. The surface of the snowpack will freeze, but a strong crust will not form will soften earlier than the day before. Above approximately 2200 m snow will fall from the afternoon. The weather conditions facilitated a gradual strengthening of the snow drift accumulations. 5 to 15 cm of snow has fallen since Sunday above approximately 2500 m. Since Sunday the wind has been moderate to strong at times in some localities. As a consequence of the southwesterly wind the wind slabs have increased in size moderately on Monday. Towards its surface, the snowpack is moist and its surface has a crust that is strong in many cases. New snow and wind slabs are lying on a moist old snowpack. Below approximately 2100 m a little snow is lying.

As a consequence of the moderate to strong wind the avalanche prone locations will become more prevalent as the day progresses.
