Avalanche Activity

Weak old snow esp. on shady slopes - increasing wet-snow avalanches during the day

Avalanche prone locations for dry-snow avalanches occur above 2000 m, mostly in seldom-tracked steep terrain. Transitions from shallow to deep snow, e.g. entries into gullies and bowls, require caution. Avalanches are possible particularly by large additional loading. Small fresh snowdrift accumulations in high-altitude exposed spots should be circumvented. A cautious route selecdtion is recommended. Due to solar radiation and daytime warming, small to medium sized wet-snow and glide-snow avalanches are possible during the course of the day.

Snowpack Structure

In the upper and mid-parts of the snowpack are expansively metamorphosed (faceted) layers, mostly blanketed to a sufficient degree, thus unlikely to trigger. If at all, then in transitions from shallow to deep snow. These danger zones are not visible to the naked eye. In higher exposed ones there are small, older snowdrift accumulations. Due to solar radiation and daytime warming the snowpack often forfeits firmness during the day.

Weather Synopsis

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.

Tendency

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.
