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

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

Weak layers in the uppermost part of the snowpack can in isolated cases be triggered by one sole skier. Such danger zones occur esp. on steep N/W/E-facing slopes above 2100m. Avalanches can in isolated cases grow to medium size. Due to solar radiation and daytime warmth, increasingly frequent wet-snow avalanches can be expected, especially on extremely steep sunny slopes, releases mostly small-sized. Acute danger of falling on hardened snowpack surfaces in steep terrain.

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 Sunday, residual clouds will rapidly disperse to make room for the sun. Less northerly wind but in exposed terrain blowing at storm strength. Plummeting temperatures. At 2000m: -7 degrees. Source: GeoSource Austria
