Fresh snowdrifts demand route selection restraint

Fresh snowdrifts demand route selection restraint

Avalanche danger is considerable above 2200m, below that altitude danger is low. Medium-sized slab avalanches can be triggered by one sole skier in a few steep spots. The danger zones due to fresh and older drifts lie on W/N/E facing slopes, often distant from ridgelines. Caution urged esp. at entry points into very steep gullies and bowls. During the course of the day, naturally triggered loose-snow avalanches can be expected in extremely steep south-facing terrain. On steep grass-covered slopes, isolated small glide-snow avalanches are possible in isolated cases.

During the course of the day, more fresh snowfall is anticipated. Transported fresh snow will be deposited on shady slopes atop soft layers, the snowpack is moistened up to high altitudes due to diffuse light conditions. Near-surface layers often form a crust due to rain seepage. The below-average old snowpack is expansively metamorphosed at high and high-alpine altitudes. Weak layers in the uppermost part of the snowpack can be triggered. On sunny slopes, melting forms dominate in the old snowpack.

During the night, repeated bouts of fresh snowfall over 1200-1500m, the snowfall level dropping by morning down to the valley floors. On Monday, esp at low and intermediate altitudes, poor visibility due to residual clouds, more sunshine at high altitudes. Intermittent snowfall. In southern regions more sunshine and it will remain dry. Winds from the north will be brisk, 50 km/hr, along the Main Alpine Ridge gusts of 60-80 km/hr At 2000m: -8 degrees; at 3000m: -15 degrees.

Likelihood of snowdrift accumulations triggering will gradually diminish
