Treeline


Favorable conditions.Caution urged towards small drifts.

Fresh and older snowdrift accumulations are often triggerable above the treeline on shady slopes by one sole skier. Danger zones occur in steep ridgeline terrain, mostly on W/N/E facing slopes and behind protruberances in the landscape. The risks of being swept along and forced to take a fall outweigh those of being buried in snow masses. In isolated cases, small slab avalanches can be triggered on high-altitude extremely steep shady slopes, usually by large additional loading and where the snow is shallow.

Snowpack

Up to 5-15 cm of fresh snow is expected. At high altitudes it will often be transported. The fresh snow and drifts will be deposited esp. on steep shady slopes atop soft layers and are prone to triggering. On encrusted and moistened sunny slopes the fresh snow will bond better. All in allm, the old snowpack is well consolidated. At lower altitudes the fresh snow will fall on bare ground.

Tendency

Due to foehn wind and snowdrifts generating, avalanche danger levels can increase

Rising avalanche danger due to fresh snow and drifts

Fresh and older snowdrift accumulations are often triggerable above the treeline on shady slopes by one sole skier and then possibly growing to medium size. Older danger zones often difficult to recognize when blanketed with fresh snow. In isolated cases, small slab avalanches can be triggered on high-altitude extremely steep shady slopes also in the old snow, usually by large additional loading and where the snow is shallow.

Snowpack

Up to 10-15 cm of fresh snow is expected, locally up to 20 cm. At high altitudes it will often be transported. The fresh snow and drifts will be deposited esp. on steep shady slopes atop soft layers and are prone to triggering. On encrusted and moistened sunny slopes the fresh snow will bond better. All in allm, the old snowpack is well consolidated. At lower altitudes the fresh snow will fall on bare ground.

Tendency

Due to foehn wind on Monday, additional snowdrifts will accumulate, avalanche danger levels increase.
