Avalanche Activity

Small snowdrifts on shady slopes. Daytime wet-snow avalanches.

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. Monday daytime: High-altitude clouds, sunny but Sahara dust will hamper the sun somewhat. At 2000 m: +6 to +8 degrees. Moderate to strong southerly winds.

Tendency

Foehn wind will continue, and intensify in strength. Sunny despite Sahara dust and very mild. In the southern ranges, more cloud cover. Avalanche danger is subject to a daily danger cycle. Backcountry skiing tours should begin early, end early.
