Pay attention to local avalanche prone locations!
The avalanche risk is categorised as moderate, mainly at high altitudes. Locally, slab avalanches of up to medium size can be triggered in very to extremely steep terrain at high altitudes due to additional loads. Avalanche prone locations are mainly in areas adjacent to the ridgeline and in steep, filled-in bowls and gullies. Spontaneous loose snow or wet snow avalanches are rarely possible from steep, undischarged slopes at low and sometimes medium altitudes where there is a sufficiently thick snow cover, snowpack.
The snow cover, snowpack has continued to settle. However, there are still weak layers in the old snowpack locally at higher altitudes and the snow base, fundament is weakened by crystalline forms that have been transformed by building up. Depending on the hardness and aspect, the snow surface varies in hardness, sometimes crust can form and can soften somewhat, especially on sunny slopes. With the mild temperatures, the snow cover, snowpack in the low and partly medium altitudes varies from moist to wet depending on altitude and aspect.
There will be good visibility on the mountains on Friday, although some high clouds will cloud the sunshine. There will be no precipitation and hardly any wind. At 1500 m around 4 degrees, at 2000 m around 2 degrees. On Saturday, the sun will shine almost all day in the mountains. Weak to moderate winds from east to south. In 1500 m around 6 degrees, in 2000 m around 4 degrees.
The number of avalanche prone locations continues to decrease.
