Avalanche Activity

Rising avalanche danger above the timberline

Freshly generated snowdrift accumulations and weak layers in the old snow are prone to triggering. One single winter sports enthusiast can trigger small-sized slab avalanches. Danger zones occur especially near ridgelines and in wind-loaded gullies and bowls, as well as in extremely steep terrain. Apart from the risks of being buried in snow, the danger of being swept along and forced to take a fall require caution.

Snowpack Structure

Fresh snowfall is anticipated: 15-30cm. It will be transported by intermittently strong to storm-strength westerly winds. The fresh snow and fresh snowdrifts since Thursday frequently lie deposited atop a loosely-packed, faceted and expansively metamorphosed old snowpack surface or on surface hoar. Bonding is poor.
