Circumvent snowdrifts

Circumvent snowdrifts

Snowdrift accumulations which are prone to triggering were generated particularly in gullies, bowls and behind protruberances in the landscape due to fresh snow and increasingly storm-velocity SW winds. Snowdrifts can be triggered by one single skier. Avalanches can in isolated cases trigger naturally and grow to medium size. They can also trigger in the weak layers in isolated cases and grow to medium size. Particularly unfavorable are shady slopes. Size and frequency of danger zones will tend to increase with ascending altitude.

Up to 30 cm of fresh snow was registered regionally, locally more. Often moderate winds transported the fresh fallen snow. The fresh snowdrift accumulations were deposited atop a weak old snowpack surface particularly on NW/N/SE facing slopes above 1800m. The old snowpack is expansively metamorphosed, and faceted. The snowpack is highly diverse even over small areas.

On Wednesday, high-fogbanks will persist, upper border at 1600-2100m, sunshine above that altitude. Strong, in exposed terrain storm-strength SW winds will prevail. At 1000m at midday: +2 degrees; at 2000m: -2 degrees.
