Avalanche Activity

Considerable avalanche danger at high altitudes

One single person can trigger slab avalanches in the old snow. If the fracture sweeps away the entire snowpack, the release can grow to medium size. Danger zones occur especially on steep shady slopes and in wind-loaded gullies and bowls in all aspects. Whumpf noises and fractures on the snowpack surface are alarm signals. Also remote triggerings continue to be possible. In addition, small-sized fresh snowdrifts require special caution in high altitude ridgeline terrain and pass zones. Activities in backcountry demand experience in evaluating the terrain and assessing dangers.

Snowpack Structure

Bonding of the most recent fresh snowfall and freshly generated snowdrifts to the often faceted, expansively metamorphosed old snowpack surface, as well as inside the unfavorably structured layers of the old snow, continues to be moderate-to-poor in places. In addition, layers inside the latest fresh snow and drifted snow are often still prone to triggering. Settling noises and fractures on the snowpack surface confirm this trigger-sensitivity.

Weather Forecast

Thursday will begin with widely dispersed layers of clouds. During the morning hours, the cloud cover will recede to the east and a few hours of sunshine can be expected. Temperature at 2000m: +1 degree; at 3000m: -6 degrees. Moderate-strength southwesterly winds at high altitude, with some foehn-wind impact.

Tendency

No significant change is anticipated. The old snow remains prone to triggering at high altitudes.
