Avalanche report for Wednesday 19 March 2025.
The current avalanche situation calls for careful route selection.
all day it applies above the treeline considerable avalanche danger, so danger level three, below low avalanche danger, so danger level one.
all day, above the treeline, we have a wind slab problem. This in all aspects.
Furthermore, all day, above the treeline, we have a persistent weak layer problem. Especially in the aspects West to North to East.
The fresh and somewhat older wind slabs can be released by a single winter sport participant in some cases. Wind-loaded slopes where weaknesses exist in the old snowpack are unfavourable. The avalanche prone locations are to be found in particular on little used shady slopes above approximately 1800 m. Avalanche prone locations are to be found also on sunny slopes in high Alpine regions. The number and size of avalanche prone locations will increase with altitude. On very steep shady slopes the avalanches can penetrate down to the ground and reach large size. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. The weather conditions will give rise to increasing consolidation of the snowpack.
And now the snowpack:
The more recent wind slabs are poorly bonded with the old snowpack. Precarious weak layers exist in the centre of the old snowpack in particular on little used shady slopes. The solar radiation will give rise as the day progresses to increasing softening of the snowpack on sunny slopes. Increase in danger of moist snow slides in particular in steep rocky terrain. Below the tree line a little snow is lying.
We have the following danger patterns: dp.6: cold, loose snow and wind, dp.9: graupel blanketed with snow.
The tendency for Thursday 20 March 2025 indicates a steady avalanche danger.
