Low avalanche danger, but persistent weak layer problems in the northern and eastern exposures!
The avalanche risk is low. In the northern and eastern exposures, there is still a persistent weak layer problem at altitudes above the tree line. In steep terrain, avalanches can be triggered in a few places. Fresh wind slabs can also be triggered as snow slabs. However, even if the old snowpack is torn through, the avalanches usually remain small.
There is still significantly less snow than average. Some new fallen snow is covering surface hoar or angular forms on the north side. The foundation is still weak.
The evening and night will bring some snow or rain showers with partly brisk westerly to north-westerly winds from the main Alpine ridge northwards, with only isolated showers to the south. On Friday morning, the last snowfall in the northern Alps will subside in the morning, followed by fairly sunny weather throughout the mountains.
On Saturday, clouds will rapidly gather again from the south-west, with rain and snow in the afternoon. A cold front with strong winds and a drop in temperature will follow in the night to Sunday. The avalanche risk is expected to increase at the weekend!
