Avalanche Activity

Assess with caution: fresh snowdrifts near ridgelines and behind protruberances. Often blanketed danger zones in old snow.

Avalanche danger above 2200m is moderate, below that altitude danger is low. Freshly generated snowdrift accumulations can be triggered by one sole skier and reach medium size where snow is sufficient. Danger zones occur esp. on NW/N/NE facing slopes, esp. near ridgelines and behind protruberances in the terrain and at entries into steep gullies and bowls. Danger zones often blanketed, making them difficult to recognize. Avalanches in the old snow above 2200m are isolated, possible only in extremely steep terrain on north-facing slopes. During the course of the day, naturally triggered loose-snow avalanches can be expected in all aspects, releases will be generally small-sized. On steep grass-covered slopes, very isolated small glide-snow avalanches are possible.

Snowpack Structure

Up to 40cm of fresh snow has been deposited on steep shady slopes above 2200m atop an expansively metamorphosed snowpack. Fresh snowdrift accumulations have often been generated therefrom. Also the loose fresh snow from earlier is settling, gaining bonding. Weak layers occur in transitions to the old snowpack surface (faceted crystals) and inside the bonded fresh snow and drifts (loose fresh snow). The drifts stop this and the increasingly bonded fresh snow form the requisite slab. On sunny slopes and at lower altitudes, the bonding of fresh fallen snow to the old snowpack is generally good, weak layers are found only inside the newly generated drifts. Weak layers in the lowermost part of the snowpack are no longer likely to trigger.

Weather Forecast

On Sunday, good visibility, widespread sunshine. In the morning, residual fog can be a perturbance. Winds will be light. At 2000m: -4 degrees; at 3000m: -9 degrees. On Sunday night, skies will be star-studded.

Tendency

As temperatures gradually rise, likelihood of triggering will recede
