Update of the avalanche report for Wednesday 11 December 2024.
Snowdrifts often prone to triggering
all day it applies above 1800 meter moderate avalanche danger, so danger level two, below low avalanche danger, so danger level one.
all day, above 1800 meter, we have a wind slab problem. This in all aspects.
Avalanche danger above 1800m is moderate, danger is low below that altitude. Fresh and older snowdrifts are the major problem, these can trigger a small-to-medium sized slab avalanche by minimum additional loading in some places. They are blanketed by just a bit of fresh snow, making them hard to recognize. Danger zones occur near to ridgelines, in all aspects and in wind-loaded gullies and bowls. Frequency of avalanche prone locations tends to increase with ascending altitudes.
And now the snowpack:
Winds from varying directions have generated snowdrift accumulations over the last few days. In some places there are trigger-sensitive intermediate layers evident. The last cm of fresh fallen snow on Monday fell without much wind. At high altitudes of the Allgau Alps on sites where the snow is shallow, there is a layer of facted crystals beneath a thin melt-freeze crust in the old snowpack. The old snowpack at high and high alpine altitudes is marked by wind influence. Snow depths vary a great deal.
Have a nice day and don't forget to be careful!
