Avalanche Activity

Fresh snow and older drifts prone to triggering

Fresh fallen and frequently covered older snowdrift accumulations are easily triggered. Slab avalanches can be triggered by minimum additional loading and grow to medium-sized releases. Settling noises when treading the snowpack and fractures on the surface are indicators of imminent danger. Danger zones occur in wind-loaded steep terrain, behind sharp drops in the landscape, in gullies and bowls. In very steep terrain, loose-snow avalanches are possible due to solar radiation and daytime warming.

Snowpack Structure

The fresh snow and drifts from recent days frequently blanket older snowdrift accumulations. Amid intermittently strong winds it will be transported and will generate new snowdrift masses. They are prone to triggering. Fresh snow and drifts often lie deposited atop soft layers of fresh fallen snow from precious days and blanket older drifts. The old snowpack is generally well consolidated and compact.

Weather Forecast

Often limited visibility due to fog and remaining snow shower. During the daytime hours, slight improvement in weather conditions with a few sunny intervals, especially in the Bregenzerwald mountains. But visibility remains poor. Temperature at 2000m: from -11 to -7 degrees; at 3000m: -16 to -11 degrees. Moderate to brisk easterly winds at high altitude.
