AVALANCHE DANGER  

from Monday afternoon / evening: strong wind + fresh snow above unfavorable surface

Monday 1/27/2020
  

2000 m

   

Avalanche problem: wind-drifted snow.

Until Monday afternoon the strong wind forms new small soft accumulations. The situation worsens and the degree of danger rises from late Monday afternoon/evening when new fresh snow drifted is added which settles on unfavorable layers: formation of highly unstable windloads.

Triggered avalanches: especially along the border ridges, in the afternoon new soft accumulations are formed above 2200 m, especially at eastern exposures, near ridges and passes. A skier/hiker can easily trigger soft slabs, especially small, rarely medium (size 1 or 2). The biggest risk is being dragged down the slope.áFrom Monday evening the situation changes and can become critical.

Natural avalanches:áuntil Monday afternoon only a few small slabs at high altitude are possible, then possible superficial slabs that are at first soft then also hard.

GENERAL CONDITION
updated to 1/26/2020
 

Snow cover and Snowpack
Due to the long period without big snowfall, the snowcover locally starts to be scarce, it starts to be good over 2000 m.áIn the lateral valleys snow cover continue above 1700-1900 m at south, above 1300-1500 m at north. In the central area of the Region snow cover level is higher. Uprising in altitude, there are eroded areas especially above 2800 m, close to bumps and ridges.
On cold slopes there are many layers of faceted crystals that will be an unfavorable base for the new snow with strong winds.
Good stability: generally snowpack without internal tensions.

Observed avalanches (last 24h): no one.

Skiing conditions: not so good.
Many slopes with hard snow from wind (N-NW) or from refreezing (steep S-SW): technically difficult uphill. The snow changes in a small space: old tracks, sastrugi, even non-load-bearing crust, etc. Some areas with soft snow (faceted crystals) in the cold slopes sheltered from the wind (NE-N-NW). Stones outcropping near ridges and hills.
