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.

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.
