Avalanche Activity

Fresh snow + storm winds

Avalanche danger above the treeline is CONSIDERABLE, below that altitude danger is low. Avalanche prone locations are found wherever fresh snowdrifts have been deposited on steep slopes. There, the snowdrifts can be triggered even by minimum additional loading. Caution urged in very steep zones of gullies, bowls and behind protruberances. Potential slabs are small to medium-sized.

Snowpack Structure

Added to the snowfall at the start of the week (max. 15 cm) an additional 15-25 cm will still come. The NW storm winds will generate fresh snowdrift accumulations, these will be deposited atop the cold base and be prone to triggering. The fresh snow will blanket older snowdrifts and crusts, beneath which are soft, faceted crystal layers. However, these are fracture-relevant only in isolated cases in case of very large additional loading.

Weather Synopsis

On Wednesday, stormy NW winds (60-80 km/hr) will bring snow showers from the north. Heavy cloud cover will reduce visibility, alternating with windows of sunshine. At 2000m: -7 degrees. On Thursday, a few snowflakes only in early morning, thereafter it will be dry. Clouds will disperse gradually, visibility improve, winds slacken off significantly. At 2000 m: -2 degrees, measurably milder.

Tendency

On Thursday, no signficant change. AVOID steep wind-loaded zones.
