Weak layers in the old snow can trigger in isolated cases

Weak layers in the old snow can trigger in isolated cases

Weak layers in the old snow can be triggered in many cases by one sole skier on NW/N/NE facing slopes esp. above 2000m. Caution in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls. Due to fresh snow and northerly winds, trigger-sensitive snowdrift accumulations were generated in gullies, bowls and behind protruberances in the landscape. Avalanches can reach medium size.

At mid-level inside the snowpack, esp. on N/NW/NE facing slopes where the snow is shallow, faceted, espansively metamorphosed weak layers are evident. The snowpack is highly diverse even over small areas. Not much snow on the ground for this juncture of the season.

Wednesday will being radiantly sunny weather. Residual high-fog will rapidly disperse, making room for cloudless skies for many hours. In late afternoon, a few thin clouds will move in from the west. Winds will shift to W/NW, intensify somewhat (30 km/hr). At 3000m: -9 degrees; at 2000m: rising from -10 to -5 degrees in afternoon; at 1000m from east to west: -4 to 0 degrees.
