The current avalanche situation calls for careful route selection.

As a consequence of warming during the day, the likelihood of natural moist avalanches being released will increase gradually.

Shady slopes where weaknesses exist in the old snowpack are precarious. The avalanche prone locations are to be found in particular on steep, little used 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.

The older wind slabs can be released by a single winter sport participant in isolated cases.

Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. Backcountry tours should be started and concluded early.

Snowpack

dp.10: springtime scenario
dp.1: deep persistent weak layer

As a consequence of sharply rising temperatures a treacherous avalanche situation will develop. The surface of the snowpack will soften during the day. Sunshine and high temperatures will give rise as the day progresses to a loss of strength within the snowpack over a wide area.

Precarious weak layers exist in the centre of the old snowpack in particular on little used shady slopes.

Below the tree line a little snow is lying.

Tendency

The meteorological conditions will facilitate a slight strengthening of the snowpack on Saturday. The snowpack remains quite unstable.
