Heed: fresh snowdrifts

Avalanche danger above 2200 m is moderate, below that altitude danger is low. Fresh snowdrift accumulations can be triggered in some danger zones by 1 person, releases usually small. Danger of falling outweighs that of snow masses. Danger zones increase with ascending altitude, occur esp. behind discontinuities and in gullies and bowls on W/N/E facing slopes. Drifts are easy to recognize and should be circumvented. Above 2300 m there are near-surface weak layers in the snowpack, triggerable in some places by 1 person, large-sized releases possible, esp. on very steep shady slopes. There is continuing latent danger of glide-snow avalanches, usually small.

Due to intensifying southerly foehn wind, fresh snowdrift accumulations are still being generated. Above 2000 m on shady slopes there is 10 cm of loose snow atop a melt-freeze crust generally capable of bearing loads. Below this and on sunny slopes at all altitudes the fresh snow from Wednesday is already moist and has formed a new crust. At intermediate altitudes the snowpack has become moist repeated times and is very compact. Below 1400 m there is hardly any snow on the ground.

On Sunday the foehn wind will reach its acme, blowing at storm strength in high-altiude regions and foehn lanes. North of the Main Alpine Ridge cloudbanks will pass through, intermittent sunshine is possible, visibility reduced. At 2000 m: 0 degrees; at 3000 m: -5 degrees.

Avalanche danger levels are not expected to change significantly.
