Avalanche danger forecast for
Wednesday 4/14/2021


 

AVALANCHE DANGER  

Recent small slabs in altitude, especially along th NW border. Cold for the period.

Wednesday 4/14/2021
  

>2400 m

   

Avalanche problems: wind-drifted snow.
Recent accumulations at high altitude, especially in the northwestern border ridge of the region.
Positive aspect: the instability is superficial and therefore more easily identifiable.

Triggered avalanches
Above 2400 m, small or medium-sized surface slabs can be triggered by the passage of a skier/hiker on very steep slopes. The slabs are mostly soft. Dangerous points: the slopes just below ridges and hills and the abrupt changes of slope downwind. They are larger and thicker along the foreign border ridge.

Natural avalanches
Some recent snow discharges from rocky bars and on extreme slopes.


AVALANCHE DANGER TREND  Thursday 15:    Friday 16:  

Steady.


GENERAL CONDITION
updated to 4/13/2021
  Please note: in the closed ski-resorts areas slopes are not managed and must therefore be considered as potentially avalanche terrain

Snow cover
Snow cover is lower than the average for the period and is often scarce in the mid-mountain and southern slopes. Snow cover is irregular, best in the north-west of the region. For ski touring, in the south the snow is sufficiently continuous above 2400-2500 m, in the north above 1800-1900 m. Bumps and ridges are often eroded and the leeward gullies are loaded with snow.

Snowpack stability
The old snowpack is stable also thanks to the sharp drop in temperatures. At high altitudes, soft slabs of wind blown snow have formed over the recent fresh snow, which acts as a weak layer.Especially on the north and north-east aspects there are internal weak layers that are not currently giving stability problems.

Avalanches observed last 24h
Some sluffs of fresh snow from very steep rocky slopes have been reported.

Skiing conditions
Alternation of loose snow and windy snow, especially on the northern slopes and at high altitudes. At lower altitudes, hard old snow. Still useful knives or crampons.
