Avalanche Activity

Fresh snow & snowdrifts at high altitudes. Gliding snow problem persists.

Avalanche danger is moderate above 1500 m. Fresh snow and with ascending altitude increasingly large snowdrift accumulations can trigger a small slab avalanche. Danger zones occur on steep ridgeline slopes and in gullies and bowls. Apart from the danger of being buried in snow, also the risks of being swept along and forced to take a fall need to be considered. In steep terrain, forest lands and on grassy slopes, glide-snow avalanches can be expected in all aspects, reaching small-to-medium size.

Snowpack Structure

The latest round of snowfall has settled, up to intermediate altitudes it has bonded with the old snowpack. At high altitudes this process takes longer. Gusty winds were moderate, small snowdrift accumulations were generated. These and the fresh snow are often prone to triggering. At intermediate altitudes the snowpack is moist down to the ground, despite dropping temperatures. Gliding movements continue to be possible.

Weather Forecast

Nocturnal hours: dry, with clouds dispersing. Saturday: At 1000-1500 m, eesp. in Bregenzerwald mountains and Prealps, tenacious fog. Initially cold, temperatures rising during the day. At 2000 m: -6 to +1 degree. Moderate to brisk N/NE winds.

Tendency

Sunday will be very sunny and very mild. Gliding snow activity will increase again. The danger of dry-snow avalanches will decrease.
