Often still trigger-sensitive: older snowdrift accumulations on high alpine ridges, extremely steep slopes

The snow from the last few days has been able to settle further. On shady slopes it lies atop cold, powdery layers of old snow. On sunny slopes, often atop melt-freeze encrusted old snowpack surfaces. Bonding to them and inside the new layers themselves is generally good, but worsens with ascending altitude. The old snowpack is well consolidated and stable. Weak layers beneath melt-freeze crusts at mid-level of the snowpack can ordinarily be triggered only be large additional loading.

Outstanding visibility, generally cloudless skies. Temperature at 2000 m: -2 degrees. Moderate NW winds.

Favourable conditions prevail, avalanche danger is low. Isolated slabs and loose-snow avalanches can be triggered by winter sports enthusiasts in the uppermost layers of the old snowpack, but these are generally small-sized. Such danger zones are mostly in high alpine ridgeline terrain, on extremely steep, usually shady slopes. Apart from the risks of being buried in snow, the hazards of being swept along and taking a fall need to be considered.

Thursday will be quite sunny with some high-altitude clouds, avalanche danger will remain low.
