||Due to the ongoing precipitation accompanied by very strong and stormy winds from WNW, the avalanche danger level is 3-considerable along the ridge bordering with France and Switzerland, from the Val di Rhemes to the upper part of the Lys valley (moderate amounts of fresh snow), while it varies between 2-moderate and 3-considerable elsewhere.|
Main avalanche problems: wind-drifted snow.
Above 2500-2800 m, due to very strong/stormy winds, the loose snow (fresh and recent) is mostly sublimated and swept away with the result of strongly eroded ridges and bumps, while at intermediate altitudes, between 1600 m and 2500 m, it is easier that widespread medium-sized wind accumulations will form at all aspects.
Attention - in the areas most affected by the snowfall a layer of surface hoar is incorporated and constitutes a potential plane for the sliding of the fresh snow. |
Triggered avalanches also inside the forest: especially where it is sparse (larch woods), the passage of only one skier/hiker can trigger superficial slabs, even of medium size, on the steep slopes, at all aspects - in particular on slope changes, entry of channels, but also on the open slopes.
Natural avalanches: recovering during the day with:
- loose snow sluffs from the very steep slopes, at all aspects and altitudes;
- slab avalanches, in some cases of medium size, which, when detached from high altitudes, may in individual cases reach the bottom of the valley, going a long way. Unfortunately, the avalanche channels are already partially obstructed, so a new avalanche could come out of the usual margins;
- under 2200-2000 m full-depth avalanches of wet snow, which in some cases could affect the road network.
Trend of the avalanche danger: stationary.
