Avalanche danger forecast for
Wednesday 1/13/2021


 

AVALANCHE DANGER   From the afternoon snow storm and winds from N-NW -> slabs in formation throughout the Region.
Wednesday 1/13/2021
  

> 2200


< 2300 - 2400

Avalanche problem: wind-drifted snow -áhard and compact slabs forming close to leeward ridges / hills or bumps - andápersistent weak layers.

Along the N border ridge and on Mont Blanc area there will be new snow in addition to strong winds.
Medium-sized slab avalanches are possible here:
- naturals -áat the highest altitudes by very steep slopes close to rocky ridges or bars;
- accidentals -áeven when the individualáhiker/ski mountaineer passes, beyond the tree line, on steep slopes, especially near the ridges and on changes in slope.á

On the rest of the territory, locally assess the effects of the wind on the snowpack, which will in any case form new slabs in the leeward areas.
Accidental avalanches: on very steep slopes, aáhiker/ski mountaineer can trigger surface small-medium slab avalanches, above 2300-2500 m.

Please note: the slopes in the ski-resorts areas currently closed are not managed and must therefore be considered as potentially avalanche terrain.


AVALANCHE DANGER TREND  Thursday 14:    Friday 15:  

Generally constant Thursday, but locally it could increase depending on the effect of strong wind on the snowpack.


GENERAL CONDITION
updated to 1/12/2021
 

Snow cover and snowpack
Improved but still poor especially in the central area of the valley and in the areas of Gran Paradiso and Valpelline where stones or shrubs can still be seen below 2000 m. Better at higher altitudes.
Above 2300-2500 m the snowpack was partly redistributed by the winds with eroded bumps and ridges alternating with channels with more snow. As you get closer to the summit ridges, the accumulations are thicker and harder. As you get closer to the summit ridges the accumulations are harder.
Especially on cold slopes, the snowpack has an unfavourable basal structure due to the presence of weak layers.á
Thanks to the cold, however, the slabs that were present are disintegrating.
However, conditions are changing rapidly, first of all along the NW and N border ridge, due to the strong winds and new snow expected this afternoon.

Avalanches observed last 48h
Sluffs from very steep slopes / rocky bars in the sun above 2600 m.

Skiability
Nice powder snow thanks to the low temperatures. But still pay attention to touch stones or shrubs to the shallow depths below 2000-2200 m and near ridges and bumps more eroded by the wind.
