In orographic barrier areas 40cm of new snow possible by Friday evening.

Above approximately 1800m avalanche danger is moderate; below it is low. Main problem: fresh snow. In the main precipitation areas medium-sized slab avalanches can be triggered by low additional loading especially close to ridgelines. Spontaneously triggered medium-sized loose snow avalanches can be expected in extremely steep terrain. Avalanche prone locations are found in steep terrain in all aspects; frequency and size increase with ascending altitude. In addition, isolated small to medium-sized glide snow avalanches can release on steep slopes with smooth ground.

At high altitude, up to 40cm of fresh snow will have fallen by Friday evening. At lower altitudes the snow is deposited atop a favorable old snowpack surface. In particular at high altitudes the fresh snow is deposited atop the small quantity of fresh snow of Thursday which constitutes a potential weak layer. Adjacent to ridgelines the snow is transported by moderate wind over a spatially limited area. At low and intermediate altitudes, the new snow is deposited atop bare ground or atop a thoroughly moist old snowpack which is wet a ground level.

As a consequence of dropping temperatures, precipitation, and rising wind the avalanche danger can increase further.
