The fresh snow and the wind slabs are in some cases prone to triggering.

Backcountry touring and other off-piste activities call for meticulous route selection. As a consequence of new snow and strong wind the wind slabs will increase in size additionally. In addition the sometimes deep wind slabs are capable of being triggered in many locations. In particular along the border with France and along the border with Switzerland the prevalence and size of the avalanche prone locations will increase. The natural avalanche activity will gradually increase. These can in particular be released in near-surface layers. Places where weaknesses exist in the old snowpack are especially unfavourable. In particular here the avalanches can be triggered in deep layers of the snowpack and reach large size in isolated cases.

Thursday: 10 to 20 cm of snow fell in the late morning above approximately 2000 m. Up to 40 cm of snow, and even more in some localities, will fall until Friday above approximately 2000 m. The strong wind will transport the new snow significantly. The fresh wind slabs will be deposited on a weakly bonded old snowpack especially on very steep shady slopes.

The natural avalanche activity will gradually decrease.
