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.

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.

On Thursday, still radiantly sunny, often cloudless skies and outstanding visibility. Slight foehn wind influence, southerly winds mostly light, moderate-to-strong only in exposed terrain. At middaay at 1000m: +12 degrees; at 2000m: +4 degrees. Source: GeoSphere Austria
