Persistent weak layers
- All elevations
Favorable. Few danger zones in transitions where the snow is shallow

Avalanche danger is LOW. Only in very few places can large addtional loading trigger a slab avalanche, most likely in transitions where snow is shallow, into deeper snow, in shady and extremely steep terrain. Then, avalanches can grow to medium size. Most avalanche prone locations occur in NW/N/NE aspects distant from ridgelines and in steep gullies. Naturally triggered avalanches: extremely isolated small glide-snow avalanches can release. In the afternoon
On shady slopes there is old powder (2 weeks old, faceted, atop surface hoar) atop a compact old snowpack. Foehn winds over the last 24 hours have transported next to no snow. Small snowdrift patches are possible. On sunny slopes the melt-freeze crust in some aspects and gradients (S/SW, 1500-2000m) can bear loads, then softens up during the daytime (the upper 5-10 cm softens). Hidden inside the old snow are soft layers of expansively metamorphosed (faceted) crystals, but are unlikely to trigger except in isolated cases.
Monday will bring high-altitude cloudbanks, otherwise sunny, pleasant backcountry touring weather conditions. Light winds. At 2000 m: -1 degree. Tuesday will have diffuse light conditions, compact high-altitude cloud cover will dominate, sunshine will be impeded. Winds light. At 2000 m: +5 degrees.
No significant change is expected.
