Wind slab
- Above 2,400 m
Wind slabs and stones are the main danger.
No significant change on Thursday, but freshening north-westerly winds may deposit fresh wind slab on a small scale.
Wind slabs and stones are the main danger.
The avalanche risk is low. At high altitudes, small snow slabs can still be triggered in a few places in the wind slab. Be careful in the area of terrain traps, where enough snow could accumulate to bury people. Avalanche prone locations behind area adjacent to the ridgeline, crests or summits and in gullies and bowls are usually easily recognisable, but danger areas due to stones under the thin snow cover are often not.
The snow cover, snowpack is highly variable. Wind slabs lie on a crusted can form surface of old snow. Underneath are layers of faceted crystals, deep frost and melt-freeze crusts. However, the potential for fracture propagation is generally low. On the sunny slopes, the snow cover, snowpack is hard and crusted can form, or the subsoil is only thinly covered. The snow depth is still well below average at all altitudes.
On Wednesday, visibility will often be limited by dense clouds, with light and unproductive snowfall in places. The afternoon will bring a few clear spells, but the sky will only clear up more frequently towards the evening. The wind will be mostly weak from the west, in exposed high areas moderately strong with peaks around 30 km/h from the north-east. At 2000 metres around -14 degrees, at 3000 metres around -19 degrees.
