Rising avalanche danger above the treeline due to fresh snow and wind.

Rising avalanche danger above the treeline due to fresh snow and wind.

Fresh snow is expected: 5-10 cm. Above the treeline, fresh, small snowdrift accumulations will be generated. Avalanche headquarters currently has little data from outlying regions about the snowpack, for that reason a cautious on-site evaluation is important. Below the treeline, avalanche danger is low. Isolated danger zone for small triggerings (slides) are possible in steep terrain.

Up to intermediate altitudes, the shallow snowpack has been weakened by rainfall. During the coming night of partially clear skies, it will regain firmness. By Saturday evening, an additional 5-10 cm of fresh snow is anticipated, to be transported by winds. Above the treeline, and with ascending altitude, particularly in ridgline and pass areas, fresh and initially small snowdrift accumulations will be generated. They are prone to triggering in ridgeline zones and, in particular, in steep wind-loaded gullies and bowls.Rising avalanche danger above the treeline due to fresh snow and wind

Friday will begin with gloomy and stormy weather, rainfall up to 2000m to start with. In early morning the snowfall level will descend to 1300m, but there will also be bright intervals during the morning hours. Thereafter, conditions will become variable and windy, with clouds, sunshine and isolated showers. At 2000m: dropping from +1 to -5 degrees. Strong to stormy westerly winds at high altitudes.

As a result of some fresh fallen snow and wind influence, avalanche danger can rise slightly.
