Beware persistent weak layers. Rising daytime danger of wet-snow avalanches.

Beware persistent weak layers. Rising daytime danger of wet-snow avalanches.

Due to solar radiation and daytime warmth, increasingly frequent wet-snow avalanches can be expected, including medium-sized releases, on very steep E/S/W-facing slopes, esp. below 2700m. Morning: acute danger of falls on the hardened crust on steep dlopes. Weak layers in the uppermost part of the snowpack can in isolated cases be triggered by one sole skier, danger zones occur esp. on steep N/W/E-facing slopes above 2400m. Isolated danger zones also occur on steep south-facing slopes above 2600m. Isolated avalanches can fracture down to more deeply embedded layers of the snowpack and grow to medium size.

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.

On Saturday, once again very sunny and mild. In afternoon, some harmless clouds will move in from the north, later on become denser. Visibility will remain good. The N/NW winds will be light to moderate. At 1000m: +18 degrees; at 2000m: +6 degrees. Source: GeoSource Austria
