Avalanche Activity

Persistent weak layer esp. on shady slopes

Avalanche prone locations for dry-snow avalanches above 2000 m on shady slopes, particularly in transitions from shallow to deep snow, e.g. at entries into gullies and bowls. Triggerings are possible especially by large additional loading. Small drifts in high-altitude exposed zones should be avoided, esp. on shady slopes. A prudent route selection is recommended.

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. On very steep sunny slopes at low altitudes there is a crust on the surface in early morning. Otherwise the snowpack is often powdery.

Weather Synopsis

Nocturnal hours: mostly cloudy skies but it will remain dry. Friday: variably cloudy to heavily overcast, only little sunshine. Slight precipitation is possible, snow above 1800 m. At 2000 m: 0 to +2 degrees. Moderate to brisk NW winds.

Tendency

Saturday will be quite sunny and very mild. Strong NW winds at high altitude, leading to fresh snowdrift accumulations being generated. Risk of wet-snow avalanches will rise again.
