Avalanche problem #1 :
Storm slab will continue to form at all elevation and on all aspect with the snow received and forecasted for Friday night. Also, the wind will increase and turning. This will form wind slab at the top of E-SE-S-SW alpine slope and at treeline. With a CONSIDERABLE danger rating, natural avalanche triggering is possible and human triggering is likely. Take the time to carefully evaluate the snowpack and be really conservative with your decision-making about your itinerary.
In the alpine and at treeline, the new snow received since Friday morning (10 to 20 cm depending of the area) lay on the snow of this week for a total of 30-40 cm depending of the area. This snow covers either hard wind slabs or the crust formed by mixed precipitation of January 26th. SW-W and N alpine aspects lack generally some snow cover. Below treeline, up to 30 cm of snow covers now the January 26 crust. The snow conditions vary greatly in the mountains and many obstacles are still present at the surface. The depth of snow on the ground varies generally from 50 to 200 cm.
Friday night: 10 to 15 cm, northerly wind blowing at 65 km/h, temperature in the alpine of -16 C.
Saturday : 1 cm in the morning and then clearing, strong north wind decreasing to moderate and turning NW in the afternoon, temperatures in the alpine -16 C.
Sunday : Sunny, moderate to strong westerly wind, alpine temperature -17 C.
Monday : Snow flurries, less than 2 cm, westerly light wind, alpine temperature -8 C.
