Significant avalanche danger, wind slab problem! Beginning wet snow problems at lower altitudes.

Significant avalanche danger, wind slab problem! Beginning wet snow problems at lower altitudes.

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 and occasionally large slab avalanches can be triggered by individuals in many places. Spontaneous wet snow avalanches can occur at lower altitudes and spontaneous gliding avalanches on steep grassy slopes.

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 both within the wind slab and in the transition to persistent weak layers. Where a snow base, fundament is present, it is crusted can form and hard. 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 +3 degrees during the daytime changes. The wind will blow from the northwest, increasing during the daytime changes and becoming strong towards the evening.

The unsettled, rainy and mild north-westerly weather conditions continue at the start of the week. The drifting snow problem is easing.
