Snowdrift accumulations trigger-prone at high altitudes

Snowdrift accumulations trigger-prone at high altitudes

Main danger: fresh snowdrifts, often blanketed by loose fresh snow. Danger zones occur in steep ridgeline terrain, behind discontinuities and in wind-loaded gullies and bowls and increase with ascending altitude. A small-to-medium slab avalanche or loose-snow avalanche can be triggered by 1 person (sometimes larger). Beware the dangers of being swept along and forced to take a fall. Glide-snow avalanches are still possible, esp. with solar radiation. Caution urged below glide cracks.

A little fresh snow and snowdrifts lie deposited atop soft layers at high altitudes or atop older snowdrifts, otherwise otherwise atop a hard old snowpack surface. Occasionally gusty S/SW winds have generated fresh snowdrift accumulations, bonding is only adequate. Inside the fresh snow are often weak layers. On high-altitude shady slopes the surface is powdery, elsewhere there are often melt-freeze crusts and wind crusts evident. Warm ground and the wet old snowpack plus the load of fresh snow on top of it are reinforcing gliding movements. Below 1400 m there is very little snow on the ground.

Nocturnal hours: Heavy cloud cover, not much longwave outgoing radiation. Monday daytime: Cloud but dry, little sunshine and then, only weak. Im the Rätikon and Silvretta, peaks can be shrouded in clouds. At 2000 m: -2 to 0 degrees. Moderate-to-strong southerly winds.

In the Rätikon, Silvretta and Verwall a bit of minor snowfall is possible, elsewhere it will be dry. Strong southerly winds will continue to transport the snow. Danger of dry-snow avalanches is not expected to change. Glide-snow avalanches are still possible.
