Fresh snow and drifts are highly prone to triggering
Fresh fallen and frequently covered older snowdrift accumulations are easily triggered. Small to medium-sized slab avalanchess can be triggered by minimum additional loading. Also naturally triggered avalanches can be expected. Settling noises when treading the snowpack and fractures on the surface can indicate imminent danger. Danger zones occur in wind-loaded steep terrain, behind sharp drops in the landscape, in gullies and bowls. Particularly in high-altitude west, north and east-facing slopes, avalanches can fracture down to ground-level layers of the snowpack and grow to large size. I
Snowpack
By Tuesday morning there was up to 40cm of fresh snow registered widespread, locally as much as 50cm. Amid intermittently strong winds it was transported and has generated new snowdrift masses. They are prone to triggering. Fresh snow and drifts often lie deposited atop soft layers of fresh fallen snow from precious days and blanket older drifts. The mid-part of the snowpack consists of well-consolidated, compact layers which in shady slopes blanket a poorly-structured snowpack fundament.

Fresh snow and drifts prone to triggering
Fresh fallen snow and snowdrift accumulations are easily triggered. Slab avalanchess can be triggered by minimum additional loading and grow to medium-sized releases. Settling noises when treading the snowpack and fractures on the surface can indicate imminent danger. Danger zones occur in wind-loaded steep terrain, behind sharp drops in the landscape, in gullies and bowls. Particularly in high-altitude west, north and east-facing slopes, avalanches can fracture down to ground-level layers of the snowpack and grow to large size. In very steep terrain, also loose-snow avalanches are possible.
Snowpack
Widespread up to 30cm of fresh snow is anticipated, up to 40cm in the Rätikon. Amid intermittently strong winds it will be transported and will generated new snowdrift masses. They are prone to triggering. Fresh snow and drifts often lie deposited atop soft layers of fresh fallen snow from precious days and blanket older drifts. The mid-part of the snowpack consists of well-consolidated, compact layers which in shady slopes blanket a poorly-structured snowpack fundament.

Fresh snow and older drifts prone to triggering
Fresh fallen and frequently covered older snowdrift accumulations are easily triggered. Slab avalanchess can be triggered by minimum additional loading and grow to medium-sized releases. Settling noises when treading the snowpack and fractures on the surface can indicate imminent danger. Danger zones occur in wind-loaded steep terrain, behind sharp drops in the landscape, in gullies and bowls.
Snowpack
Widespread 20-30cm of fresh snow is anticipated. Amid intermittently strong winds it will be transported and will generated new snowdrift masses. They are prone to triggering. Fresh snow and drifts often lie deposited atop soft layers of fresh fallen snow from precious days and blanket older drifts. The old snowpack is generally well consolidated and compact.
