On Friday, cloudy skies with some bright intervals. Snowfall expected in the afternoon above 1400-1800 m. Avalanche danger levels are not expected to change significantly.
Wet-snow avalanches where rain impact. Small snowdrifts at high altitudes.
In steep rocky terrain and where there is rain impact, increasingly frequent wet-snow avalanches can be expected. On steep grass-covered slopes and over rock plates in all aspects, small glide-snow avalanches continue to be possible. Caution below glide cracks. Small snowdrift accumulations at high altitudes are prone to triggering, the occur behind discontinuities and in wind-loaded gullies and bowls. Small isolated medium-sized avalanches can be triggered by one person. Mind the risks of being swept along and taking a fall.
The snowpack is wet up to high altitudes due to heavy rainfall, increasingly forfeiting its firmness. The warm ground and wet lower layers are reinforcing the gliding movement of the entire snowpack. Strong to stormy winds are transporting the loose snow, generating trigger-prone snowdrift accumlations. Older drifts are bonding better with the surface, but with increasing altitude are still prone to triggering, esp on high-altitude shady slopes, inadequate bonding. The old snowpack below them is generally well consolidated and stable. In zones with rain impact, however, the snowpack is being weakened, in some places with graupel.
Thursday daytime: Heavily overcast skies with frequent rainfall and snowfall during the daytime hours. From Allgäu Alps and Arlberg region into the Verwall, persistent and often heavy precipitation. Above 2200 m: 30-50 cm of fresh snow possible; below 1600-1800 m as sleet and rain. At 2000 m: 0 degrees. Strong W/NW winds.
