Beware snowdrift accumulations at high altitudes

Beware snowdrift accumulations at high altitudes

At high altitiudes snowdrift accumulations are often trigger-prone, easily triggerable as small avalanches. Evaluate the snowdrifts with caution in steep terrain. Danger zones occur on north-facing slopes agove 2400 m in very steep terrain, esp. in transitions from shallow to deep snow, e.g. at entries into gullies and bowls. Glide-snow avalanches can trigger below 2600 m at any time of day or night and reach large size. Caution urged below glide cracks. Due to rain impact, mostly small-sized wet loose-snow avalanches can be expected.

As a result of strong foehn winds, fresh snowdrift accumulations have been generated, the lie deposited esp on shady slopes atop soft layers. On north-facing slopes above 2400 m, near-surface weak layers have persisted. The old snowpack is generally compact and stable. At low and intermediate altitudes it is thoroughly wet down to the ground. Clouds passing through will hamper nocturnal longwave outgoing radiation, a crust capable of bearing loads cannot form easily.

Nocturnal hours: The foehn wind will come to an end, it will be cloudy but dry. Monday daytime: Dry weather, variably cloudy, some sunshine, some fog. At 2000 m: -1 to +2 degrees. Light to moderate easterly winds.

Tuesday will be variably cloudy with some precipitation, somewhat cooler. Danger of wet-snow avalanches will recede slightly, otherwise avalanche danger levels are not expected to change significantly.
