Beware persistent weak layers. Rising daytime danger of wet-snow avalanches.
Weak layers in the uppermost part of the snowpack can in isolated cases be triggered by one sole skier, they occur esp. on steep N/W/E-facing slopes above 2100m, avalanches can grow to medium size. Due to daytime warming and solar radiation, increasingly frequent wet-snow avalanches can be expected, also medium-sized releases, esp on very steep sunny slopes. In the morning hours: danger of falling on the hardened crusts in steep terrain.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Inside the old snowpack on N/W/E-facing slopes there are faceted, expansively metamorphosed weak layers, esp. abov 2100m. Clear skies over far-reaching areas: due to low temperatures and low air moisture, surface crusts will form. Sunshine and warmth will moisten the snowpack during the daytime. The snowpack at low and intermediate altitudes is moist. Below 1500m there is little snow on the ground.

Rising daytime danger of wet-snow avalanches.
Due to daytime warming and solar radiation, increasingly frequent wet-snow avalanches can be expected, mostly small-sized releases, esp. on steep sunny slopes. In the morning: beware falls on the hardened crusts.
