Persistent weak layers in high altitudes! Observe: fresh snowdrift deposits are present in some areas.

Moderate avalanche danger above 1.900 m, below that: low avalanche danger. Danger spots are located in high shady slopes behind ridgelines and in the beginnig of gullies and bowls as well as steep slopes. Slab avalanches within the old snow can be triggered by small additional load and can reach medium sizes especially in transition areas from thin to thicker snow covers. Due to the new snow amounts and the strong winds snowdrift deposits which are prone to triggering are possible which are to consider especially for risk of falling. Also spontaneous gliding snow avalanches are possible. Avoid areas below glide cracks.

THursday night only little snow has fallen. Snowdrift deposits in shady slopes are on a loss old snow cover. The bonding between driftsnow and old snow is poor. Summits are blown-off and icy or bare, gullies and bowls are filled with snowdrift. In shady high altitudes the snow cover is weakened due to layers of faceted snow crystals and sometimes snown in Graupel within the old snowdrift accumulations. Surface hoar has formed especially in basins. On smooth surfaces the snow cover can start gliding any time.

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.

No significant changes of the avalanche danger situation. Due to warming the snow cover will get moist. Little rain is expected.
