Weather Forecast

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.

Avalanche Activity

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

Below the treeline, no marked avalanche problem exists. Isolated danger zones for small releases (slides) occur in extremely steep terrain. Apart from the danger of being swept along, the risks of being forced to take a fall also require consideration. Above the treeline, small fresh snowdrift accumulations are forming, they are prone to triggering and easily unleashed as small slab avalanches. There is still little data coming into headquarters from the outlying regions. On-site, cautious evaluation is recommended.

Snowpack Structure

A bit of fresh snowfall is anticipated, deposited atop a well-consolidated, shallow snowpack. At high altitudes this snow is being transported by strong to storm-strength winds, thereby generating small snowdrift accumulations especially in ridgeline and pass zones above the treeline. These drifted masses will grow during the course of the day. Particularly in wind-loaded gullies and bowls they are trigger-sensitive.

Tendency

Due to more snowfall and wind impact, avalanche danger will rise significantly over the weekend.
