Moderate avalanche danger above 2300m, below 2300m danger is low. Main problem: trigger-sensitive intermediate layers at ground-level in the old snow. Isolated slab avalanches can be triggered on shady steep slopes be large additional loading, particularly where the snow is shallow, i.e. at entries to gullies and bowls. Triggered avalanches can be of small-to-medium size.
Melt-freeze encrusted surfaces (hard as steel, icy, breakable, snowdrift patches, melt-freeze from the rain) dominate. Inside the snowpack the recent layers are relatively well bonded. A potential trigger-sensitive layer of faceted and soft snow is at high altitudes. The tendency towards fracture propagation is moderately strong.
On Wednesday, sunshine and outstanding visibility. Winds will be mostly light. At 2000 m: -3 degrees, at 3000 m -8 degrees. On Thursday cloudbanks will pass through, the summits will remain free, but light conditions will become diffuse. Higher temperatures: at 2000 m about 0 degrees, at 3000 m -5 degrees. Winds will be northwesterly, blowing often at brisk strength.
Little change.
