Avalanche Activity

Caution urged on steep, shady high-altitude slopes

Slab avalanches can be triggered in the old snow in some places with large additional loading. Caution is urged on very steep, shady high altitude slopes. Small-sized snowdrift accumulations can be triggered with increasing frequency at ascending altitudes. Small-to-medium sized slab avalanches can be triggerred by winter sports enthusiasts. Especially on steep grass-covered slopes, small-sized glide-snow avalanches continue to be possible. Be careful beneath glide cracks.

Snowpack Structure

Only small amounts of snowfall are being registered. As a result of the mild temperatures and influence of rainfall, the snowpack is moist up to high altitudes. The fresh fallen snow and small-sized snowdrift accumulations from the last few days are settling increasingly and firming up. At heightened altitudes they were often deposited on top of faceted layers of old snow from late autumn. The bonding is poor in places.

Weather Forecast

A weak cold front will bring a bit of snowfall during the nighttime hours, falling down to nearly 800m. Residual clouds will soon disperse and during the daytime widespread sunshine is expected. Only in areas surrounding the Bregenzerwald will the persistent residual fog reach up to 1200m in places. Temperatures at 2000m: -3 degrees. High altitude winds: blowing at moderate strength from the southwest.

Tendency

Avalanche danger is expected to recede further.
