Significant avalanche danger above the tree line! Avalanche prone locations difficult to recognise!
The avalanche risk is considerable above the tree line and moderate below. Avalanche prone locations are snow-covered slopes of all aspects, in particular in the east and south sectors. Particular caution is required behind terrain edges and in entrances to gullies and bowls. Medium-sized slab avalanches can be triggered by individuals in many places.
Wind from various directions has led to heavy transported snow and fresh wind slabs in all aspects over the past few days. The east and south sectors are particularly affected. Weak layers are possible in the transition to persistent weak layers. The snow base, fundament is weakened by faceted crystals and floating snow. At lower elevations, the snow becomes moist and loses firmness. On steep meadow slopes, the snow can begin to glide.
The night into Sunday will bring snow mainly from the main ridge northwards, with only isolated showers expected to the south. The unsettled mountain weather will continue on Sunday. Overall, however, dry conditions will prevail and the sun will appear at times. The temperature at 2000 metres will rise from -3 to +2 degrees during the daytime changes. The wind will blow from the northwest, increasing during the daytime changes and becoming brisk towards the evening.
The unsettled, rainy and mild north-westerly weather conditions continue at the start of the week. The drifting snow problem is slowly easing.
