Bregenzerwald Mountains

Freshly generated snowdrift accumulations demand caution. More slides and glide-snow avalanches due to rain impact.

Fresh and older snowdrifts can be triggered even by one sole skier. Danger zones occur particularly on steep shady slopes, in wind-loaded gullies and bowls and behind protruberances in the terrain. Size and frequency of danger zones tend to increase with ascending altitude. In regions where there has been rain impact an on steep grass-covered slopes, glide-snow avalanches are possible. Caution urged below glide cracks.

The fresh snow and drifts lie deposited atop an unfavorable, expansively metamorphosed old snowpack surface, often atop surface hoar, on shady slopes in particular. Also inside the snowdrifts themselves there are frequently trigger-sensitive intermediate layers evident. On sunny slopes, bonding to the old snowpack surface is better. In zones where there has been rain impact the snowpack is being temporarily weakened.

Morning hours will be sunny, then clouds will move in above summit level. In the afternoon, clouds will become denser. By evening, cloud will be heavy even at lower altitudes. Temperatures will rise at all altitudes. At 2000m: from -12 to -4 degrees. Brisk westerly winds at high altitudes, in the evening strong-to-stormy.

Storm-strength southerly winds will transport the snow and generate new drifts, thus, avalanche danger can increase regionally.
