The storm will continue until Tuesday and it will be possible to have some natural avalanches in the alpine. It will also be necessary to watch the few slopes whose the snowpack will have covered the roughness of the ground and where the storm snow could be triggered by a skier or snowboarder.

The storm will continue Sunday night and Monday for a great total of 20-30 cm. This new snow will promote the development of storm slabs throughout the day on all steep slopes in the alpine and at treeline. These slabs will be sensitive during their formation and 24 hours after. Remember that even a small avalanche can have serious consequences by dragging you towards obstacles (trees, rocks, stumps) further down the slope.
Recent storm snow (15-25 cm) and strong westerly winds forecasted for Tuesday night and Wednesday will promote the development of wind slabs in the upper section of alpine slopes. These slabs will be more reactive during their formation. Skiers triggers are possible in localised areas on leeward slopes.

The northwest wind picked up on Wednesday afternoon and is expected to continue to blow moderately overnight and on Thursday. A lot of storm snow available for transport will shift and create thick wind slabs on the NE to S slopes of the alpine and at treeline.
Conditions on Monday were perfect to develop fresh wind slabs. These add up to the previous ones to create 40-60 cm wind slabs. Continous strong  north-westerly winds will increase their hardness and thickness on Tuesday.
