Weather Synopsis

Nocturnal hours: mostly a night of clear skies and good outgoing radiation, some high clouds as morning approaches. Wednesday: clouds above the peaks will hamper the sunshine, create diffuse light conditions, most summits will remain free. The clouds will descend as the day progresses. At 2000 m: +3 degrees. Light SW winds.

Tendency

Thursday will be heavily overcast and foggy, a few minor snow showers. The danger of dry-snow avalanches is not expected to change significantly. The danger of wet-snow avalanches will increase slightly during the day.

Avalanche Activity

Mostly favourable conditions throughout the morning hours

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.

Snowpack Structure

The snowpack is generally well consolidated and stable in the morning. On shady slopes there are weak layers in places. The snowpack loses its firmness during the day on steep sunny slopes and at low altitudes.
