Avalanche Activity

Caution: snowdrift accumulations and persistent weak layer at high altitudes, slides and loose-snow avalanches as a result of higher temperatures

Danger zones occur mostly in shady extremely steep terrain. Isolated small slab avalanches are possible by large additional loading. If fractures occur at deeply embedded layers of the snowpack, the old snowpack can be swept away and avalanches grow to large size. At high altitudes small snowdrift accumulations require attentiveness. Naturally triggered small slides are possible, on steep grassy slopes isolated small-to-medium glide-snow avalanches

Snowpack Structure

Recent fresh snow deposited atop a stable, below-average snowpack, well consolidated in the morning, softening only slightly later in the day. The snowpack fundament is thoroughly wet up to high altitudes, can glide over smooth ground in all aspects. Below 1200-1400 m there is not much snow on the ground.

Weather Synopsis

Nocturnal hours: above 1000 m snow showers will slowly taper off. Sunday: residual clouds will disperse in the morning, sunshine will soon reign, visibility improve. Some residual or convective cloud might persist. Minor snow showers in the afternoon. At 2000 m: -4 degrees. Light to moderate NE winds.

Tendency

Easter Monday will be mostly sunny, high-altitude clouds will move in from the west during the afternoon. Danger of dry-snow avalanches will not change much, danger of wet-snow avalanches will increase.
