Fresh snow and drifts often deposited atop unfavorable old snowpack

Fresh snow and drifts often deposited atop unfavorable old snowpack

Avalanche danger is considerable above 2000m, avalanches can be triggered by one sole skier in places and grow to large size. Fresh snowdrift accumulations lie deposited behind protruberances in the terrain, and in gullies and bowls. Danger zones in the old snow occur on north-facing slopes above 2200m, above 2400m in all aspects. Avalanches in the weak old snow can fracture deeper down and grow to large size. Due to solar radiaiton during the afternoon hours, naturally triggered loose-snow avalanches can be expected. At higher altitudes, releases can sweep along moistened snow masses in the course of their plummet path and in very isolated cases even reach green areas. Small to medium-sized glide-snow avalanches can trigger naturally in very steep grass-covered terrain.

By Sunday midday, 30-50cm fresh snow at high altitudes. Above 2200m on north-facing slopes: weak layers of faceted crystals in lowermost part of snowpack. Above 2400m on W/S/E-facing slopes: faceted crystals between crusts. Inside the snowdrift accumulations, trigger-sensitive layers can quickly form. Below 2000m the old snow is moist, a crust has often formed on the surface.

On Sunday rainfall and snowfall in the morning hours amidst dense clouds. At midday, clouds will disperse and some sunshine is expected. In evening, clouds will move in widespread from the NW and on Sunday night, rain and snow will fall. Very windy, the W/NW winds will intensify during the course f the day and reach 70 km/hr. At 2000m: -2 degrees, at 3000m: -7 degrees C. On Sunday night the snowfall level will drop to below 1000m and temperatures will fall.

On Saturday night, fresh snowdrifts will accumulate due to fresh snow and wind
