Caution: weak layers in old snow.
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.
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.
On Wednesday, high-pressure front conditions over the Alps. Brilliantly sunny, cloudless skies, outstanding visibility. Light southerly winds. At 2000m: +4 degrees; at 1000m: up to +11 degrees. Source: GeoSphere Austria
