Wind slab
- Above 1,600 m
Still considerable avalanche danger at higher altitudes!
On Friday, there will still be a few clouds from the north, but it will soften a little during the daytime changes. In the south of the Alps, it will be cloudy in the morning and sunny in the afternoon. The wind slab problem will slowly subside.
Still considerable avalanche danger at higher altitudes!
The avalanche danger above 1600 m is assessed as "considerable". Persistent winds lead to extensive snowdrift accumulations, some of which are prone to triggering. Avalanche prone locations are mainly in gullies, bowls and behind ridgelines and terrain edges and sometimes extend down into forest aisles. Aspects from north to east to south are particularly affected. The drifting snow layer can be triggered in some places by a small additional load as a mostly medium-sized slab avalanche. Occasionally, large avalanches can also occur.
The new fallen snow and winds of the past few days have created snowdrift accumulations, some of which are very thick and are deposited on a largely stable old snowpack. The proneness to triggering of weak layers in the windslab snow is decreasing, but weak layers in the transition to persistent weak layers and in the snow base, fundament are still possible, especially on the north side.
The sky will remain mostly cloudy on Thursday, with a few snowflakes falling in the northern congestion. The peaks will often be in the clouds and visibility will be impaired. The wind will blow briskly, even strongly from the north-west on the main Alpine ridge. The temperature at 2000 metres above sea level is between -6 and -3 degrees.
