Consider fresh snowdrift and persistent weak layers.

The avalanche danger is moderate above the treeline. Danger spots fas thin, prone to triggering snowdrift accumulations especially behind ridgelines, steep slos and blown-in gullies and bowls in the extended Exposition North and East above thetreeline. Theses aqre easily spottet for experts. In very steep, shady and high slopes slab avalanches within the old snow can be triggered by small additional loads and slab through deeper layers within the old snow. They can reach medium sizes. Danger spots are increasin in higher altitudes. on steep slopes with smooth surface spontaneous gliding snow avalanches are possible.

Thursday night anf during firday approx. 10 cm cold new snow with strong wind influences has fallen. This snowdrift (bonded) accumulates on a loose snow layer in shady slopes. This layer is built by kinetic metamorphism (faceting) - in sheltered locations also by surface hoar - and is a potentially breakable crust for slab avalanches. The bonding is on sunny slopes with crusted surface a bit better. On smooth surfaces the snow cover can start gliding anytime.

There is an intensive low-pressure system in the peripheral area of the eastern Alps on Saturday. In the Nordstau regions dense clouds and little snow. It clears up during the morning hours. Sunny in the area of Alpenhauptkamm und routheasterly regions but from noon on thin high altitude clouds are comingn from west and intensify later to dense clouds. THe vivid to stron northwesterly winds will trasform to vivd southwesterly foehn winds which gests eventually stronger in the east. The temperatures are rising and will be around -12 degrees in the morning but -6 degrees in the afternoon in 2.000 m. In 1.500 it will increase from -9 to -4 degrees.

The snow cover will get mois due to rain on Sunday. In some areas increasing of small wet loose-snow avalanches ind regions with high amounts of snow.
