Danger level

Treeline


Avalanche danger is moderate. Snowdrift accumulations above 2000m can often trigger a small-to-medium slab avalanche by one sole skier. Danger zones occur particularly in ridgelines zones and behind protruberances in the landscape. Superficially triggered releases above 2200m can fracture down to deeper layers of the snowpack. Danger zones occur in all aspects. Caution urged in transitions from shallow to deeper snow. Due to fresh snow, gliding snow activity will slightly increase. Caution urged below glide cracks.

Snowpack

Up to 20-30cm of fresh snow is expected, locally more. Winds in exposed terrain will be blowing above transport velocity, thus generating fresh snowdrift accumulations especially in ridgeline terrain. Weak layers for slab avalanches lie inside the fresh snow and fresh drifts. On shady slopes above 2000m the old snowpack can itself be a weak layer. Above 2200m there are several weak layers of faceted crystals inside the old snow, often prone to triggering. The entire snowpack can glide over steep rocky plates or grass-covered slopes.

Tendency

Little change expected before Wednesday

Fresh snowdrifts accumulating near ridgelines

Avalanche danger above the treeline is moderate. Where fresh snowfall transported, trigger-sensitive snowdrifts accumulating in some places which can be released by one sole skier. Danger zones occur particularly in ridgelines zones and behind protruberances in the landscape. Small-to-medium glide-snow avalanches still possible. Caution urged below glide cracks.

Snowpack

Up to 10-20cm of fresh snow is expected, deposited atop a widespread favorable old snowpack surface. Where winds reach transport velocity, soft layers will be generated inside the fresh snow and fresh drifts which can be weak layers. The entire snowpack can glide over steep rocky plates or grass-covered slopes.

Tendency

Avalanche danger levels expected to decrease slightly

Fresh snowfall, not much wind

Avalanche danger levels above 200m is moderate, below that altitude danger is low. Shallow snowdrift accumulations can be triggered in some places as a small-sized slab avalanche even by minimum additional loading (one skier), particularly on W/N/S facing slopes. Above 2200m, weak layers inside the snowpack can also be triggered in isolated cases. The shallow-snow transitions in snow-filled gullies and bowls are especially treacherous. Danger zones tend to increase in frequency with ascending altitude.

Tendency

Snowdrift problem intensifying due to increasing southerly foehn winds
