Update of the avalanche report for Friday 13 December 2024.

On shady slopes isolated danger zones due to weak layers in old snow. Evaluate fresh snowdrifts with caution.

all day it applies above 2400 meter moderate avalanche danger, so danger level two, below low avalanche danger, so danger level one.

all day, above 2400 meter, we have a persistent weak layer problem. Especially in the aspects West to North to East. Furthermore, all day, above 2400 meter, we have a wind slab problem. Especially in the aspects North-West to North to North-East.

Avalanche danger as of 2400m is moderate, danger is low below that altitude. On shady slopes at high and high-alpine altitudes, small-to-medium slab avalanches can be triggered in the old snow. In addition, small, fresh snowdrift accumulations will be generated near ridgelines during the course of the day. Danger zones occur mostly in transitions from shallow to deep snow, e.g. at the edge of gullies and bowls and behind protruberances in the landscape. Danger zones tend to increase with ascending altitude. The weight of one persons is sufficient to trigger a slab in steep terrain.

And now the snowpack:

At high and high alpine altitudes, fresh and older snowdrift accumulations have been deposited on the surfaces atop loosely-packed layers of older snow or atop surface hoar, both of which are prone to triggering. Beneath these layers, the snow which has persisted since September and November as fundament is weakened by layers of faceted crystals. The snow is distributed highly irregularly: ridges are often totally windblown, but elsewhere the fresh fallen snow also doesn’t cover the base.

The tendency for Saturday 14 December 2024 indicates a steady avalanche danger.

Have a nice day and don't forget to be careful!
