Avalanche Activity

Snowdrifts at high altitudes still prone to triggering in places

Particularly in ridgeline zones and in very steep gullies and bowls, small-area freshly generated snowdrift accumulations are evident, mostly small sized but prone to triggering. Esp. on shady high-altitude slopes they can be triggered even by one sole skier. Danger zones tend to increase in frequency with ascending altitude, evaluate these with high caution wherever falls are possible. Naturally triggered small loose-snow avalanches are naturally triggerable on extremely steep sunny slopes.

Snowpack Structure

Fresh snowdrift accumulations, lie deposited on shady steep slopes atop weak layers and are prone to triggering. Elsewhere, the snowpack is stabilizing. The near-surface layers are still generally loosely-packed, except where winds have had their effect. There are lots of wind crusts and, on south-facing slopes, a shallow surface crust. More deeply embedded layers inside the snowpack are unlikely to trigger, at most where the snow is shallow and on very steep shady slopes. Particularly in sunny aspects, glide cracks are opening again on steep grassy slopes.

Weather Forecast

Dry and often clear skies Tuesday night, more clouds accumulating in early morning hours. On Wednesday, widespread high-altitude cloudbanks will soon thin out, often sunshine will later prevail. Foehn winds will intensify, otherwise wind will not be significant. At 2000m: -1 to +3 degrees. Light to moderate SW winds.

Tendency

No significant change anticipated in avalanche danger levels
