Forest fire risk in Valais

There is also a high risk of forest fires in parts of canton Valais. In the Visp Valley, Simplon Nord and south of the Lötschberg, the government has even declared the highest danger level 5. At this level, there is a risk of very hot fires, large-scale crown fires or sparks flying over long distances, according to the hazards portal.

Fires can break out at any time and spread very quickly over long periods of time – as such, fires should be lit outdoors, authorities recommend.

In the Valais areas of Sion-Sierre, Nicolai, Binn and Saas, the danger level is also high at warning level 4, while in the rest of the canton the forest fire danger is still considerable at level 3. The situation is less worrying in the rest of Switzerland.
