Avalanche Activity

Often favorable conditions in morning, wet-snow avalanches during the course of the day

Avalanche danger is low in the morning, during the course of the day increasing slides and small-to-medium wet-snow avalanches in sunny steep terrain. Also: glide-snow avalanches are possible at any time of day or night. Avoid zones below glide cracks. Fresh small snowdrifts can trigger a slab avalanches in steep shady terrain above the treeline behind discontinuities and in wind-loaded gullies and bowls. Beware the risks of being forced to take a fall.

Snowpack Structure

The lower parts of the snowpack are wet up to high altitudes, this reinforces gliding movements. Small drifts are trigger-prone esp. on shady slopes. Nocturnal outgoing radiation is good in spite of nocturnal clouds, often forming a melt-freeze crust, softening quickly the next morning, causing the snowpack to forfeit its firmness. Because ski areas are closed there is little information about snowpack layering at high altitudes. Apart from the snowpack wetness, no marked avalanche problem prevails.

Weather Forecast

Nocturnal hours: Dry, mild, good nocturnal outgoing longwave radiation. Tuesday daytime: Mild foehn conditions, high clouds and Sahara dust will hamper the sunshine. At 2000 m: +10 degrees. Moderate southerly winds, stronger in foehn lanes.

Tendency

Foehn wind will continue. Sunny despite Sahara dust and very mild. Avalanche danger is subject to a daily danger cycle, rises as the day progresses. Backcountry skiing tours should begin early, end early.
