Decrease in danger of moist and wet avalanches as the temperature drops.

Decrease in danger of moist and wet avalanches as the temperature drops.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field. Outgoing longwave radiation during the night will be quite good. During the day: In some localities a little new snow above approximately 1800 m. Gradual decrease in danger of moist snow slides as the temperature drops. The wind slabs are to be found especially in gullies and bowls, and behind abrupt changes in the terrain. They are mostly small and can be released in isolated cases. These avalanche prone locations are to be found on very steep slopes. In addition small wind slabs formed adjacent to ridgelines and in pass areas on Friday.

In all aspects snow depths vary greatly above approximately 2200 m, depending on the infuence of the wind. Below approximately 1500 m: No snow is lying on south facing slopes. The snowpack is largely stable. It is not distinctly layered. In particular sunny slopes: As a consequence of highly fluctuating temperatures and solar radiation a crust formed on the surface during the last few days, also above approximately 2300 m. Some gliding avalanches and moist snow slides have been released on very steep sunny slopes.

Decrease in danger of moist snow slides as the temperature drops. The avalanche danger will persist.
