Still wind slab problem in the high altitudes!
The avalanche danger is rated as "moderate" above the tree line. There, fresh snowdrift accumulations can still be triggered as slab avalanches by low additional loads. Medium-sized avalanches are typically expected. The avalanche prone locations are on lee slopes behind terrain edges and in steep gullies and bowls.
Strong winds are still forming fresh snowdrift accumulations. These are located on a mostly stable old snowpack. There are weak layers in the wind-driven snow and occasionally, in shady high altitudes, also in the snow base, fundament (persistent weak layer problem).
The sky will remain mostly overcast on Thursday, a few snowflakes may still fall in the area of the main Alpine ridge and the peaks there will often be covered in clouds. The wind will blow strongly from the north-west. The temperature at 2000 metres above sea level will be between -6 and -3 degrees.
On Friday, there will still be a few clouds from the north, but it will soften a little during the daytime changes. In the south of the Alps, it will be cloudy in the morning and sunny in the afternoon. The avalanche risk will change only slightly.
