Caution: wet loose-snow avalanches on very steep sunny slopes; weak layers in old snow
Due to daytime warming and solar radiation, increasingly frequent generally small-sized wet loose-snow avalanches are possible, esp. on extremely steep sunny slopes. Avalanches are triggerable by persons in the weak old snow, esp. on W/N/E facng slopes above 1800m, releases sometimes medium-sized.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Sunny slopes: Due to low temperatures and low air moisture, a surface crust forms during the nocturnal hours. Solar radiation and daytime warmth lead to significantly moister snowpack, esp. on extremely steep slopes. Shady slopes: inside the snowpack are expansively metamorphosed (faceted) weak layers, esp on W/N/E facing slopes above 1800m. The old snowpack is expansively metamorphosed (faceted) on the surface.

Avalanches are triggerable by persons in the weak old snow, esp. on W/N/E facng slopes above 2200m, releases sometimes medium-sized, esp. on very steep shady slopes and in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls.

Caution: loose-snow avalanches on extremely steep sunny slopes
Due to solar radiation, increasingly frequent generally small-sized wet loose-snow avalanches are anticipated, esp. on extremely steep sunny slopes. Avalanches are triggerable by persons esp. by large addtional loading on NW/N/NE facing slopes above 2000m, releases mostly small.
