Unfavorable avalanche situation

Unfavorable avalanche situation

Avalanche danger above the treeline is CONSIDERABLE, below that altitude danger is moderate. Avalanches can in some zones be triggered by one sole skier, esp. in the afternoon, and grow to medium size. Danger zones occur in the old snow on north-facing slopes above 2200m, in all aspects above 2400m. Above 2200m weak layers can be swept away with the releases and the avalanches thereby grow to large size. Small-to-medium glide-snow avalanches can trigger naturally in very to extremely steep grass-covered terrain.

At high altitudes 30-50cm of further fresh snow with wind impact is expected. Inside the drifts, trigger-sensitive weak layers can rapidly form. Above 2200m on north-facing slopes there are weak layers of faceted crystals in the lowermost part of the snowpack. Above 2400m on W/S/E-facing slopes there are weak layers of faceted crystals between crusts. Below 2000m the old snowpack is moist, on the surface a crust has formed. Where the ground was bare of snow before this round of precipitation, the entire snowpack can now glide away.

On Monday, clouds will accumulate due to strong-velocity W/NW winds, frequent snow showers will pass through. From tomorrow until Tuesday morning, 30-60cm of fresh snowfall is expected at high altitudes, winds will reach 70 km/hr and transport the fresh fallen snow. At 2000m: -6 degrees; at 3000m: -13 degrees.

Proneness of snowdrifts triggering will decrease slightly on Tuesday
