Moderate avalanche danger, but still a wind slab problem!
Moderate avalanche danger, but still a wind slab problem!
The avalanche risk is moderate above the tree line and low below. The main danger is fresh wind slabs in the north, east and south aspects. Adjacent to ridgelines, behind terrain edges and in entrances to steep gullies and bowls, smaller slab avalanches can sometimes be triggered by individuals. Medium-sized avalanches are also possible in the northern sector.
The snow base, fundament is largely stable. On the surface, there is fresh wind slab in places, some of which contains weak layers. Only in shady high altitudes does floating snow still weaken the snow layering.
Thursday night will be mostly partly cloudy and the easterly to north-easterly wind will weaken. Thursday will then bring sunny mountain weather with only a weak wind from the north-east. The temperature at 2000 metres above sea level will rise from -6 to -3 degrees during the course of the day.
On Friday, sun and clouds will alternate with a moderate northerly wind. The wind slab problem subsides.
