Avalanche Activity

Mostly favourable conditions

Avalanche danger is mostly low. Danger zones occur in steep shady terrain. Transitions from shallow to deep snow require caution, 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.

Snowpack Structure

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. Elsewhere the snowpack surface is still powdery, esp. on shady slopes.

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.
