Beware of fresh wind-drifted snow!
The avalanche danger above the tree line is assessed as moderate. The main danger spots are smaller, fresh accumulations of wind drifted snow in the north, east and south sectors. Smaller slab avalanches can be triggered behind terrain edges and in entrances to gullies and bowls by even a small additional load. In some places, avalanches can tear through weak layers of old snow close to the ground and reach medium-sized dimensions.
Fresh wind-drifted snow has formed in the eastern and southern sectors, which is not well bonded to the ground in places. Below this, a succession of crusts and softer layers will form an increasingly unstable snow layering in the higher altitudes.
After a cold, clear night, a few low-lying clouds will begin to accumulate on the northern edge of the Alps on Saturday morning, causing visibility problems on the mountains in places. It will remain windy and cold. The wind will blow strongly from northwest to north, temperatures at 2000 m will be around -12 degrees at midday.
The weather will remain cold and windy on Sunday. The avalanche danger remains unchanged.
