The current avalanche situation calls for careful route selection.

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.

Snowpack

dp.6: cold, loose snow and wind
dp.9: graupel blanketed with snow

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.

Tendency

Wind slabs and weakly bonded old snow require caution. Increase in danger of moist avalanches as a consequence of warming during the day and solar radiation.

Fresh wind slabs require caution.

The more recent wind slabs are in some cases still prone to triggering. Caution is to be exercised in particular on very steep shady slopes adjacent to ridgelines and in gullies and bowls above approximately 1800 m. In isolated cases avalanches are medium-sized and can be released in some cases by a single winter sport participant.

The weather conditions will give rise to increasing consolidation of the snowpack.
