Little new fallen snow.
Increase in avalanche danger due to fresh wind slab!
The avalanche risk is still low in the morning and increases to moderate in the afternoon above the tree line. In some places at high altitudes, adjacent to ridgelines and in entrances to gullies and bowls, fresh pillows of wind drifted snow in the north-west to south-east aspect can be triggered as mostly small slab avalanches.
A little new fallen snow and strong winds led to the formation of pillows of wind drifted snow. The wind slab lies on a hardness of old snowpack or on a soft layer. In the higher elevations, angular snow crystals continue to weaken the stability on shady slopes.
The evening and night into Thursday will be increasingly cloudy, but there will still be no precipitation. Thursday will also start mainly dry. It may even clear up briefly in places. However, dense clouds will quickly gather from the south-west in the morning and the mountain peaks will become increasingly foggy. In the afternoon it will start to snow south of the main Alpine ridge. The temperature at an altitude of 1500 metres will be -1 degrees, falling in the evening. Moderate winds from the east to southwest, becoming increasingly northwest to northeast in the evening.
Heavy snowfall is expected during the night from Thursday to Friday. The risk of avalanches is increasing.
