In the western sector of the Main Alpine Ridge a small amount of snowfall is possible, elsehwere it will remain dry. Temperatures at high altitude are rising: at 2000 m, -12 to -4 degrees; at 3000 m, -12 to -7 degrees. Moderate to brisk S/SW winds, stronger in the classic foehn lanes. Snow Layering The uppermost, loosely-packed layers of the snowpack are decisive to avalanche danger, since whenever drifts are deposited atop such snow, weak layers are produced. The snowpack surface on shady, until now wind-protected slopes are least favourable of all: faceted crystals and surface hoar are evident, the layer is weak and highly prone to triggering as soon as drifts are deposted on top of it. In sunny terrain the snowpack surface is often covered with melt-freeze crusts. With ascending altitude the number and spread of wind crusts tend to increase. Beneath these are also faceted, weak layers. In those zones, quite deep snowdrift accumulations are necessary to trigger the weak layer, and this is currently not the case. Avalanche Danger The intensifying winds at high altitude are increasing avalanche danger. Above 1800 m, danger levels are already considerable in general, below that altitude often low, in the foehn lanes danger is moderate. The main peril stems from freshly generated snowdrift accumulations. Highest caution is urged in steep W/N/E aspects where drifts have been deposited atop loose snow crystals and can now be triggered even by minimum additional loading. Also, naturally triggered avalanches are possible wherever the snow has been transported. In wind-protected and heavily skied terrain, conditions are quite favourable, but caution is still urged towards gliding avalanches on steep, grassy slopes.
