Avalanche Activity

Loosely-packed powder, small ridgeline drifts possible

Avalanche danger is LOW nearly up to the treeline, MODERATE above that altitude. Potential danger zones are focused on steep ridgeline terrain in N/W/S aspects where in some places fresh drifts can trigger. Even the weight of one single person is sufficient to set off a release. Avalanche prone locations are small, strictly delineated; potential slab avalanches are small-to-medium sized.

Snowpack Structure

Fresh snow (20-30 cm) loosely-packed and very cold, lies deposited on a relatively compact old snowpack which has next to no pronounced and relevant weak layers. Due to brief spells of wind impact, soft drifted masses are embedded towards the surface, deposited atop the cold, loose snow.

Weather Synopsis

On Monday the peaks will often be veiled in cloud, minor snowfall is possible. In the afternoon the clouds will gradually begin to disperse, a bit of sunshine will make itself felt. As of 2000 m, an intermittently moderate strength NW wind will be blowing at 20-30 km/hr. At 1500 m: -3 degrees; at 2000 m: -10 degrees. On Tuesday, heavy cloud cover will move in, snowfall is anticipated (about 5 cm). Above the treeline, a W/NW wind will be blowing strongly enough to transport the snow. Ongoingly cold.

Tendency

The somewhat stronger winds at high altitude will raise the danger of slab avalanches another notch.
