Bregenzerwald Mountains

Snowdrifts with ascending altitude. Increasing glide-snow avalanches.

Snowdrifts with ascending altitude. Increasing glide-snow avalanches.

Increasing small-to-medium glide-snow avalanches are possible. Avoid zones below glide cracks. Fresh small snowdrifts can trigger a slab avalanches in steep shady terrain above the treeline behind discontinuities and in wind-loaded gullies and bowls. Frequency and size of danger zones increase with ascending altitude. In case of extended bright intervals, small loose-snow avalanches are possible. Activities in outlying terrain demand experience in assessing avalanche dangers on-site. In case of extended bright intervals, more small-to-medium loose-snow avalanches will be possible in all aspects.

Fresh snow and drifts from previous days have settled and slightly consolidated, esp. at intermediate altitudes. A further 10 cm of fresh snow, intermittently transported by moderate winds, will generate new snowdrift accumulations. With ascending altitude the fresh snow and drifts will lie deposited atop soft layers and are prone to triggering. There are often weak layer inside the drifts and the uppermost layers of fresh snow (wind impact and graupel). The snowpack is moist-to-wet down to the ground up to high altitudes. The fresh snow at lower altitudes often lies deposited atop what was previously bare ground. Due to closed ski areas there is little information about snow layering at high-alpine altitudes.

Nocturnal hours: Heavily overcast skies, persistent snowfall. Wednesday daytime: Instable conditions, intermittent snowfall or graupel, possible bright intervals and sun windows. At 2000 m: -7 degrees. Moderate northerly winds shifting to westerly.

Thursday will bring some snow showers to start with. In afternoon a few bright intervals are possible. Temperatures slowly rising, light winds. Avalanche danger levels are not expected to change significantly. Gliding snow persists.
