Unfavorable avalanche conditions

Unfavorable avalanche conditions

Naturally triggered dry-snow avalanches will diminish when intensive snowfall ends. Avalanches can be triggered in the old snow even by one sole skier. In addition, avalanches can be triggered even by minimum additional loading in the near-surface layers of the snowpack, esp above 1800m. Avalanches can on shady slopes sweep along the moist layers of the old snowpack and grow to large size. Caution urged at the foot of rock walls and behind protruberances in the terrain, and in gullies and bowls. Due to moistening, increasingly frequent moist loose-snow avalanches can be expected, also medium-sized ones, esp. after a night of cloudy skies on extremely steep slopes. Caution urged in gullies along the Italian and Slovenian borders. The runout zones should be circumvented. On very steep grass-covered slopes glide-snow avalanches are possible, also medium sized releases.

Since Wednesday, 80-120cm of fresh snow has been registered above 1800m, locally more. Another 5-10cm of expected above 1600m. Winds in ridgeline zones will be moderate. Fresh snow and drifts lie deposited atop soft layers, esp. above 1800m. More deeply embedded inside the snowpack on shady slopes are faceted, expansively metamorphosed weak layers, esp. above 2000m.

Persistent low-pressure front impact, thus, clouds will remain dense, summits will remain shrouded in fog. At 2000m: -2 degrees. Winds from S/SW will be moderate.

Not much change expected
