Persistent snowdrift problem on shady slopes in the morning

Persistent snowdrift problem on shady slopes in the morning

Avalanche danger is subject to a daytime cycle. Due to higher temperatures on Monday, naturally triggered wet loose-snow avalanches in steep rough and rocky terrain are expected. Also wet naturally triggered slab avalanches are possible. In the morning, snowdrift accumulations are still triggerable on shady high altitude slopes.

The snowdrift accumulations which were generated on Saturday lie deposited atop a hardened melt-freeze crust. Bonding of drifts to the old snowpack is not sufficient. The drifted layer is 10-20 cm thick. During the daytime, the drifts will moisten and lose stability. The old snowpack is generally quite stable. At ground level the snowpack is moist-to-wet.

On Monday morning, a thick cloud layer at intermediate altitude will blanket the mountains of Styria in fog. As of midday this will disperse from the west, a sunny afternoon will begin. Winds will shift to westerly, by evening in the Koralpe a brisk wind will develop. Temperatures will rise at all altitudes. At 2000 m: +6 degrees.

On Tuesday, the summits will be veiled in heavy cloud, from the west rainfall and snowfall will set in. Snowfall level will lie at 1600 m (Dachstein region) and 2000 m (Koralpe), then descend during the course of the day to 1000 m-1500 m. A wet snow problem will threaten up to high altitudes.
