Rainfall up to 1800m, wet loose-snow avalanches expected

Rainfall up to 1800m, wet loose-snow avalanches expected

Snowdrift accumulations which are prone to triggering will be generated particularly in gullies, bowls and behind protruberances in the landscape due to fresh snow and strong-velocity winds. The freshly generated drifts can be triggered even by one sole skier. Isolated dry-snow avalanches also possible, esp. in the major areas of participation. Releases will be mostly small-sized, medium-sized in isolated cases. Size of danger zones tend to increase with ascending altitude. In addition, at 1200-1600m, wet loose-snow avalanches can be expected, small releases. Their runout zones should be circumvented.

Up to 1600m, above 1900m up to 15 cm of fresh snow is antitipated regionally, locally more, most between Hochstuhl and Koschuta. Often stormy winds will transport the fresh fallen snow. The fresh snowdrift accumulations will be deposited atop a weak old snowpack surface particularly on shady slopes and be poorly bonded to it. Further snowdrifts will accumulate during the course of the day above 1800m atop a weak snowpack. Rainfall is expected up to 1800m widespread, leading to widespread loss of firmness inside the snowpack.

On Thursday, dense clouds all day long, rainfall especially in the morning hours, then also snowfall (snowfall level at 1400-1800m). Moderate to strong velocitdy SW winds, stormier at high altitudes. At 2000m: 0 degrees at midday; at 1000m: 4-7 degrees.
