Avalanche Activity

Snow transport also in exposed terrain

Avalanche danger in the morning is moderate, rising to considerable above 1500 m in the afternoon. Main problem: snowdrifts. Danger zones occur near to and distant from ridges in steep terrain, gullies, bowls on N/E/S facing slopes. Also in forest clearances, drifts can be deposited. Frequency of danger zones increases as the day progresses. Slab avalanches can be triggered even by 1 person, and reach medium size. In addition, gliding snow activity is increasing. Glide-snow avalanches can release at any time of day on very steep smooth slopes naturally, at all altitudes and in all aspects. Avalanches tend to remain small. Avoid zones below glide cracks.

Snowpack Structure

At high altitudes the drifts are being deposited atop older small drifted masses and fresh snow, bonding of the layers is poor. Below the snowfall level there is rain, making the snowpack wetter than it already was, increasing the weight load and thereby, the gliding activity over smooth ground. There is no widespread cohesive snowpack at low altitudes. The fluctuating snowfall level at intermediate altitudes is at least bonding the layers better with each other.

Tendency

Persistent snowfall: avalanche danger levels increasing.
