Mostly favourable conditions in the morning. Increasingly frequent wet-snow avalanches during the daytime.
Mostly favourable conditions in the morning. Increasingly frequent wet-snow avalanches during the daytime.
Low avalanche danger in the morning. Danger zones for dry snow avalanches mostly in steep shady terrain, caution urged in transtions from shallow to deep snow, e.g. at entries into gullies and bowls. Due to higher temperatures and solar radiation, small-to-medium, in isolated cases also large-sized wet-snow and glide-snow avalanches are possible on very steep sunny slopes during the course of the day.
The snowpack is generally well consolidated and stable. On shady slopes there are weak layers in places. At high altitudes in exposed zones, fresh, small snowdrifts are apparent. On very steep sunny slopes and at low altitudes there is a melt-freeze crust capable of bearing loads in the morning hours.
Nocturnal hours: skies often overcast, clouds dispersing somewhat during the night. Saturday: partly sunny and good visibility, mild, zero-degree level at nearly 2700m. At 2000 m: 2-5 degrees. Strong NW winds in high alpine regions and ridgeline zones.
Sunday morning will be pleasant and partly sunny. From the north, clouds will then move in. Towards evening, rainfall/snowfall will set in (snowfall above 1600m). Strong winds will generate fresh snowdrift accumulations, effect a slight increase in avalanche danger levels. The risk of wet-snow avalanches will recede as temperatures drop.
