2000m


Snowdrift accumulations still trigger-sensitive, esp. on steep shady slopes at high altitude

Avalanche danger above the timberline is MODERATE, below that altitude danger is low. In all aspects, small-to-medium slab avalanches can be triggerd by minimum additional loading in places. Danger zones occur mostly near ridgelines and behind protruberances in the landscape, esp. on W/N/NE facing slopes, caution also urged near treelines and in forest clearances. Size and frequency of danger zones tend to increase with ascending altitude. Above 2000m, releases can fracture down to more deeply embedded layers inside the snowpack and grow to larger size. Small glide-snow and loose-snow avalanches can trigger naturally. Avalanche danger above 2000m is MODERATE, below that altitude danger is low. Slabs, mostly small-sized, can be triggered even by minimum additiional loading both near to and distant from ridgelines and behind protruberances in the landscape on north, northwest and south facing slopes. If they fracture down to more deeply embedded layers in the snowpack the releases can grow to medium size. Isolated glide-snow avalanches reaching medium size are possible at any time of day or night.

Snowpack

Often hardened snowdrift masses lie atop an expansively metamorphosed, loosely-packed snowpack surface with near-surface faceted crystals. Near surface crusts are weak layers of faceted, expansively metamorphosed crystals. Particularly in shady, shallow-snow zones there is snow which is rewarding to skiers, it is faceted, expansively metamorphosed powder which is settling increasingly with rising temperatures. In general, too little snow on the ground for this juncture of the season.

Tendency

Snowdrift problem receding further. Snowdrift problem stabilizing increasingly.

Avalanche danger above 2000m is MODERATE, below that altitude danger is low. Slabs, mostly small-sized, can be triggered even by minimum additiional loading both near to and distant from ridgelines and behind protruberances in the landscape on west to north to northeast-facing slopes, but caution is also urged near the treeline and in forest clearances. In isolated cases, triggerings can fracture down to more deeply embedded layers in the snowpack the releases can grow to medium size. Isolated naturally triggered glide-snow and loose-snow avalanches are possible at an time of day or night.

Tendency

Avalanche danger levels decreasing further. Snowdrift problem is receding slightly.

Danger of taking a fall outweighs that of being buried in snow

Avalanche danger is low. Particularly on very steep shady slopes above the timberline, slab avalanches can be triggered in isolated cases by minimum additional loading. Releases are mostly small-sized. Apart from th danger of being buried in snow masses, the risks of being swept along and forced to take a fall need to be taken into consideration.

Snowpack

Mostly shallow snowdrift masses lie deposited on shady slopes, often atop a weak, heavily faceted and expansively metamorphosed layer of old snow.

Tendency

No significant change in avalanche danger levels anticipated
