As a consequence of new snow and strong wind the prevalence and size of the avalanche prone locations will increase as the day progresses.

As a consequence of new snow and strong wind the prevalence and size of the avalanche prone locations will increase as the day progresses.

Above approximately 1500 m snow will fall on Thursday. The wind will be strong in particular along the border with France. As a consequence of new snow and a moderate to strong wind from westerly directions, sometimes large wind slabs will form from late morning. The fresh snow as well as the wind slabs represent the main danger. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. These avalanche prone locations are to be found also on steep slopes and in gullies and bowls, and behind abrupt changes in the terrain. They are numerous and are barely recognisable because of the poor visibility. Along the border with Switzerland and along the border with France the avalanche prone locations are more widespread.

20 to 50 cm of snow, and even more in some localities, will fall above approximately 2000 m. The cold fresh snow as well as the wind slabs will be deposited on a favourable old snowpack in all aspects. At low and intermediate altitudes only a little snow is lying.

The danger of natural avalanches will decrease gradually.
