Significant avalanche danger above the tree line! Avalanche prone locations difficult to recognise!
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 east and south. 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.
Up to 30 cm of new fallen snow was transported by winds from various directions. Fresh drifts will form in the east and south sectors over the course of Saturday. Weak layers are possible both in the fresh wind slabs and in the transition to persistent weak layers. The snow base, fundament is weakened by faceted crystals and floating snow.
The last snow showers will subside on Friday evening and the night into Saturday will be largely dry. It will also soften up temporarily. During the course of the day, a warm front will cause increasing cloudiness again, but only a little precipitation in the form of isolated showers is expected south of the main Alpine ridge. The temperature at 2000 metres above sea level will rise from -6 to -3 degrees during the day and there will be strong winds from the northwest that will increase during the daytime changes.
On Saturday and Sunday, a warm front will bring thick clouds and plenty of new fallen snow from the main ridge northwards. However, the snowfall level will gradually rise to an altitude of 1000 to 1400 metres. Increasing wet and sliding snow activity is expected from Sunday.
