Strong south winds have redistributed the new snow into dense wind slabs that may remain possible to trigger at upper elevations, especially where the new snow is poorly bonded with the old snow. The recent snow sits on a variety of snow surfaces, hard wind-scoured surfaces, preserved powder, and possible surface hoar in sheltered areas. Stay alert to changing slab conditions as you move into wind-exposed terrain, and monitor the bond of the new snow to the old snow surface.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":427,"length":12,"key":0}],"data":{}},{"key":"1fbt4","text":"A culprit weak layer of facets (sugary snow) can be found over a widespread crust that formed in early December (down 70-160 cm). This layer seems particularly reactive at treeline elevations between 1700-2100 m and in the north of the region in areas such as the Hurley. On Thursday, this persistent slab problem produced a natural avalanche cycle in the north of the region and surprised several recreationists in the neighbouring Sea-to-Sky region with large, remotely-triggered avalanches. This problem is particularly hard to predict and tricky to manage. Given the rapid load from new snow and wind along with recent avalanche activity, this persistent slab problem requires wide, conservative terrain margins and disciplined backcountry travel techniques.
