Wet-snow problem due to rain impact

Light to moderate rainfall/snowfall during the night (snowfall level at 1400-1700 m, up to 5 cm of fresh snow expected). On Sunday, heavily reduced visibility due to clouds and fog. Rainfall/snowfall esp. in the morning, snowfall level dropping to 1200 m at midday (5-10 cm expected). The W/NW winds will be moderate to strong (gusts at 30 km/hr). At 2000 m: -1 degree.

On Monday, gliding snow will remain the main problem. On sunny, extremely steep terrain, moderate naturally triggered loose-snow activity.

Wet-snow problem due to rain impact

Avalanche danger below 2200 m is moderate, above that altitude danger is low. Medium-sized wet loose-snow avalanches can be triggered naturally. In danger zones which have not yet discharged on steep grassy slopes in all aspects, glide-snow avalanches are possible at any time of day or night, medium releases possible. Avoid zones below glide cracks. In few danger zones (on steep shady slopes) isolated weak layers in the uppermost part of the snowpack can trigger, avalanches can grow to medium size.

Rain impact is burdening the snowpack stability below 1700 m. Above that altitude the fresh snow will be deposited atop moistened old snow and in wind-exposed zones atop hard melt-freeze crusts. The snowpack is thoroughly wet up to 2000 m, on sunny slopes up to 2600 m, wet down to the ground. On shady slopes above 2000 m, the snowpack still has reserves of cold, thus, loose layers can still weaken the snowpack.
