Avalanche danger is low. Main problem, isolated weak layers in the old snow. Slab avalanches can on very steep north-facing slopes still be triggered by large additional loading. Likelihood of triggering is higher in transitions from shallow to deep snow. Avalanches are small to medium-sized.
Isolated old snowdrift accumulations from the stormy weather phase are still prone to triggering. On shady slopes the lie in leeward terrain, often atop loose old snow, on sunny slopes atop a melt-freeze crust beneath which are layers of faceted crystals. Also at ground level there are layers of large-sized faceted crystals, particularly on north-facing slopes. Tests show that the stability of the snowpack is poor in those places. In some places the snowpack has settled well and the surface is powdery. On steep, sunny slopes, a thin melt-freeze crust will form on Friday night. Snowpack tests conducted by competent skiers are often helpful in deciding where to ski and where not to.
The persistent weak layer threat abides.
