Snowdrift problem
Avalanche danger above the treeline is considerable. Danger zones occur in E/S aspects where slabs can be triggered even by minimum additional loading, special caution is urged at entries into gullies and bowls and drifts behind protruberances. In rough and rocky terrain, loose-snow avalanches and slab avalanches can trigger naturally.
In the last 24 hours up to 30 cm of fresh snow has been registered. The new snow was impacted by storm-strength winds. Fresh snowdrifts blanket the surface hoar or hardened old snowpack surface. The fundament is compact and expansively metamorphosed (faceted) only where the snow is shallow.
In the southern mountains, dry in the morning, clouds dispersed, in the afternoon heavier cloud cover. Winds will be moderate to brisk from the northwest. At 2000 m at midday: -3 degrees. Mostly sunny and mild mountain weather on Friday. Winds will be moderate to brisk from the west, only as evening approaches will clouds from the northwest become heavier. At 2000 m at midday: 0 degrees.
As temperatures rise the snowpack will settle.
