Beware fresh snowdrifts. Danger zones often unrecognizable.

Beware fresh snowdrifts. Danger zones often unrecognizable.

Avalanche danger above 2200 m is considerable, below that altitude danger is moderate. Older and fresh drifts can be triggered even by 1 person in steep terrain, and reach medium size. Increasing danger zones due to shifting winds. Frequency of danger zones increases with ascending altitude, danger also rises as day progresses. At high altitudes, slabs can trigger from deeper snowpack layers, generally medium sized. Danger of naturally triggered glide-snow avalanches persists below 2300 m. Where snow is deep enough, they can reach medium size. Avoid zones below glide cracks.

By Sunday morning 15 cm of fresh snow fell widespread (focus in western regions), more will be added to it during the daytime, mostly unbonded. Brittle snowdrifts can be deposited on leeward slopes. Weak layers lie inside the fresh snow. The snowfall from Saturday fell on a largely stable snowpack. Due to the irregularity of the surface (wind-compressed, icy, windblown, loose) the weak layers are unlikely to be extensive. The old snowpack base is moist. The warm ground is reinforcing the gliding movement of the snowpack downhill.

On Sunday poor visibility, clouds and fog will dominate, repeated snowfall, by evening an additional 10 cm is expected. The northerly winds will be light. Tempertures will drop further. At 2000 m: from -7 to -10 degrees; at 3000 m: -10 degrees.

Avalanche danger levels are not expected to change significantly.
