Low avalanche danger, isolated small glide-snow avalanches.
Avalanche danger is low. Small-area wide, fresh snowdrift accumulations at high altitudes require caution. Below the treeline there is no striking avalanche problem evident. Particularly on very steep sunny slopes, isolated small glide-snow avalanches are possible. On slopes with glide cracks, caution is imperative.
On nights with clear skies, the snowpack surface metamorphosed expansively on shady slopes. On sunny slopes the snowpack surface was moistened on Friday, overnight it will form a thin melt-freeze crust. Southerly winds will generate fresh, mostly small drifted masses in higher-altitude pass and ridgeline areas. Due to intensifying westerly winds on Saturday, more trigger-sensitive snowdrift accumulations will be generated on Saturday. Depending on wind impact, the snow is distributed very irregularly, ridges often windblown, gullies and bowls often filled to the brim with snow.
A change in weather. Right from the start, heavily overcast, hardly any sunshine, clouds will lie above summit level in the morning, thus, diffuse light conditions. In the afternoon, all summits will become shrouded in clouds, a few snowflakes will fall. Temperatures will drop. At 2000m: -4 degrees. Winds shifting to W/NW and intensifying.
Due to fresh snowfall and strong northerly winds, avalanche danger levels will increase on Sunday.Due to fresh snowfall and strong northerly winds, avalanche danger levels will increase on Sunday.
