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 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. Due to light to moderate southerly winds, mostly small snowdrift accumulations are being generated, esp. on ridgeline slopes.
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. Due to southerly winds, small snowdrift accumulations are being generated. Winds are transporting only small amounts of snow. Fresh snowdrift accumulations lie deposited esp. on shady slopes atop soft layers.

Caution: 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 above 2800m. 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. Due to moderate-velocity southerly winds, mostly small-sized snowdrift accumulations will be generated esp. in ridgeline terrain.

Favorable avalanche situation
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.
