Still wind slab problem in the high altitudes!
Still wind slab problem in the high altitudes!
The avalanche danger above the tree line is rated as "moderate". Above the tree line, fresh snowdrift accumulations can sometimes still be triggered as slab avalanches by low additional loads. Medium-sized avalanches are typically expected. The avalanche prone locations are on lee slopes behind terrain edges and in steep gullies and bowls.
Strong northerly winds are still forming fresh snowdrift accumulations. These are located on a mostly stable old snowpack. There are weak layers in the drift snow and occasionally, in shady high altitudes, also in the snow base, fundament (persistent weak layer problem).
Wednesday will be variably cloudy and windy south of the main Alpine ridge. Directly on the main Alpine ridge, there will be recurring visual obstructions. The temperature at 2000 metres above sea level will be between -5 and -6 degrees. The wind will be brisk at first, decreasing during the daytime changes, from the north-east.
On Thursday, clouds will continue to accumulate from the north and a brisk north-westerly wind will blow. The avalanche risk will hardly change.
