Prone to triggering fresh wind slab.

Prone to triggering fresh wind slab.

The avalanche danger is moderate above 2200 metres and low below. Since yesterday, storms from the northwest have deposited fresh wind slab snow on an unfavourably built-up old snow surface. Small avalanches in particular can be triggered by individual people in some places from around 2200 metres. Be especially careful in terrain traps, areas adjacent to the ridgeline, crest or summit and in gullies and bowls.

The snow cover, snowpack is highly variable. In high, shady slopes, there is usually edged snow without binding under the wind slab and the melt-freeze crust. The fracture propagation potential is generally low due to the overall highly structured snow cover, snowpack. Fractures are most possible in fresh wind slab snow, above the hard old snow foundation from early winter, or very rarely in the vicinity of crusts. The snow depth is well below average at all altitudes.

Wednesday will often start quite sunny with good visibility, but clouds will gradually gather in the afternoon. The wind will blow moderately to briskly, in the high alpine areas strongly from the northwest with peaks of 60 to 80 km/h, towards the end of the day over 100 km/h. At 2000 metres around -10 degrees, at 3000 metres around -16 degrees.

The avalanche danger will remain moderate at high altitudes on Thursday.
