Small snowdrift accumulations are often still prone to triggering at high altitude
Covered snowdrift accumulations of recent days are still prone to triggering in places. They increase in size and frequency with ascending altitude. One sole skier/boarder can trigger an avalanche in steep terrain. They are generally small-sized. In isolated cases avalanches can be triggered in the old snow by large additional loading. Such danger zones are mostly in extremely steep, usually shady terrain. Apart from the risks of being buried in snow, the hazards of being swept along and taking a fall need to be considered.
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.
Wednesday will be quite sunny, temperatures will be mild. Favorable conditions, avalanche danger will be low.
