Expect the likelihood of triggering storm and wind slab avalanches to increase as new snow accumulates on Monday. On Friday, there were reports of natural and human triggered loose dry avalanches size 1-1.5.
10-20 cm of recent snow sits mainly on wind slabs and facets (sugary snow), as well as surface hoar (feathery crystals) in sheltered areas and a crust on sun exposed slopes. At lower elevations, a weak layer buried in mid January can be found approximately 50-60 cm deep. This layer consists of surface hoar and facets, and may be combined with a crust on south facing slopes. This layer has been most reactive at treeline and below. Avalanche activity on this layer has dropped off significantly, however it may still be possible to trigger avalanches on this layer in areas such as steep cutblocks, and large open glades in the trees.The lower snowpack is generally considered to be strong, except for shallow, rocky areas where cold temperatures continue to facet (weaken) the snowpack.
