Fresh snowdrift accumulations trigger-prone at high altitudes

Fresh 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). Activities in backcountry demand experience in outlying terrain and the ability to assess avalanche dangers on-site. Naturally triggered small slab and loose-snow avalanches in rocky steep terrain are possible. 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. 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: Gray skies, occasional rain/snow showers, snowfall level at 1000 m. Sunday daytime: Quite sunny weather. In the Rätikon and Silvretta, some clouds could move in from the south. In the Allgäu Alps and on the Arlberg, scattered clouds. Southerly foehn winds above the treeline will be noticeable. At 2000 m: -4 to -2 degrees. Moderate-to-brisk S/SW winds.

Monday will have compact cloud cover, foehn wind, mild temperatures. At high altitudes the loose snow will be transported, and will generate fresh snowdrift accumulations. Danger of dry-snow avalanches could increase regionally. Glide-snow avalanches are still possible.
