AVALANCHE DANGER  

cold temperatures and beautiful snow in the north-west of the Region
few snow in the south-east

Sunday 1/20/2019
  


2100-2800 m

The avalanche problems are: wind-drifted snow and persistent weak layers.

The avalanche danger is 3-considerable in the north of the Region
in the bordering areas and it rapidly drops getting away from these areas, 2-moderate in the west, south and east of the Region, 1-weak in the south-east.

Aspects to be evaluated for off-piste and ski-touring activities:
- recent small accumulations, mainly in the north of the Region, well visible and located especially above 2500 m close to ridges and passes;
- between 2100 and 2800 m on the northern slopes, there is a hidden instability in the deep snowpack: the old windloads are clearly visible and often stable, but in punctual areas one or more skiers can trigger a slabs, even thick and medium sized. The critical points are located between low and high thickness of snow. Whoom sounds are warning signs. 

Spontaneous avalanche activity absent.

Going through the south-east of the Region the windloads are much smaller in terms of thickness and number and it is rare that a fracture propagation can occur and release a slab.
The danger of slipping or falling on hard and smooth crusts is greater than the avalanche danger.
Needful crampons or ski crampons.


AVALANCHE DANGER TREND  Monday 21:    Tuesday 22:  

Costant


GENERAL CONDITION
updated to 1/19/2019
 

Snowpack and new snow
Friday evening a few cm of fresh snow (3-5 cm to 2000 m) in the southeastern sectors.
The residual instability is linked to the recent accumulations that can glide on the old and hard snowpack, but there is also a deeper instability due to layers of facets below the wind crusts.

Snowcover
The snow is absent in the valley floor and scarce in middle mountain.
Especially in the north-west, good snowcover only above 2200-2400 m, but the snowpack is heterogeneous because it is strongly worked by the wind with eroded areas even down to the ground. In the south-east the snowcover is very poor.

Avalanches in the last 24 hours
Absent

Skiing conditions: good or very good in the NW.

It is possible to wear the skis only above 1800-2300 m, better to choose skitours with roads leading at higher altitude.
In the north-west it is possible to ski on a layer of new soft cold snow, nice to ski.
Going towards the south-east of the Region we ski on both wind and refreezing crusts, hard to ski, hard and irregular.
