Avalanche Activity
Very few avalanche prone locations – persistent weak layer locally
Avalanche danger is still LOW. The snowpack is relatively stable, only in few spots can large additional loading trigger a slab, most likely where the snow is shallow and in transitions from shallow to deep snow in shady and extremely steep terrain. Avalanches can then grow to medium size.
Snowpack Structure
The snowpack has settled well, shows huge signs of storm winds. The snowdrift accumulations are well consolidated, the surfaces melt-freeze encrusted or hard. Above the treeline the terrain is utterly windblown. More snow is in the bowls. Inside the old snowpack are weak layers of faceted crystals which can be triggered in extremely isolated cases.
Weather Synopsis
On Tuesday, superb weather, visibility more than 100 km, azure skies, light winds (30 km/hr on Main Alpine Ridge in exposed zones). Slightly higher temperatures. At 2000 m: -4 degrees. On Wednesday, good visibility, initially very sunny. Clouds will move in during the afternoon, the light conditions become diffuse. Little wind. At 2000 m: -3 degrees.
Tendency
No significant change is expected. Steep sunny slopes will moisten.
