AVALANCHE DANGER   Ewcept for some wind-slab in the NW part, good conditions for theáski mountaineering.
Tuesday 3/19/2019
  
 


>2400

The avalanche danger isá3-considerable in sectors N and W, 1-low in the SE and 2-moderate elsewhere.

The avalanche problem is: "wind-drifted snow".

New and recent accumulations locally also of medium size on the South, North and East slopes above about 2400 m on the French and Swiss border ridges.


Triggered avalanches
A hiker can trigger slabs, mostly small on very steep slopes near ridges, hills and on slope changes. Persistent weak layers still characterize the snowpack on the N slopes: an eventual avalanche can still mobilize a lot of snow. Unlikely situation.


Natural avalanches
- someá slabs of small dimensions from very steep slopes under the rock bars;
- discharges and small avalanches of weakly moist snow from extreme slopes and rocks.

Decreasing everywhere.

GENERAL CONDITION
updated to 3/18/2019
 

Fresh snow and snowpack
Along the ridge of the foreign border 10-20 cm of fresh snow have fallen above 2000 m. The strong winds have created new small accumulations on the southern slopes below the ridges and hills, which add to the recent ones on the north and east slopes. The recent loose snow rests on a hard ground of old snow. On the northern slopes, between 2000 and 2500 m, there are still weak inner layers in the snow cover.


Spontaneous avalanche activity
Some small avalanches and slabs triggered by skis with very steep slopes and rocky bars.
The snow is below the seasonal average throughout the region: in the west it is better than the rest of the territory, especially in the border areas. Above 2500 m the snow is more uneven. At high altitudes, glaciers sometimes have outcropping ice.


Skiing conditions

The skis are fitted: to the north from 1600-1800 m, to the south from 2000-2200 m.Where it snowed, at high altitude, there is powdery snow in the North-West; otherwise it lasts because it is compacted by the wind at high altitude, or due to a rain crust below. Spring snow below 2800-3000 m on many southern slopes. Several eroded areas with old hard snow (useful knives).
