Although natural avalanche activity is tapering off new snow remains reactive to human triggering due to a buried weak layer.
40 to 60 cm of new snow is bonding poorly to underlying layers. Avoid north and east lee slopes where wind and new snow have formed slabs over weak layers. Watch for signs of instability: whumphing, shooting cracks and recent avalanches.
Saturday, several natural storm slab avalanches up to size 2.5 were reported. The new snow is poorly bonded to the old snow surface, and many size 1 human-triggered loose dry and storm slab avalanches were reported in steep terrain.
Storm snow totals range from 40 to 60 cm, with deeper deposits in wind-loaded areas. The new snow is boding poorly to the old snow surfaces, which includes melt-freeze crusts on sun-exposed slopes, large surface hoar or facets in sheltered areas, and wind-affected snow in exposed terrain at ridgelines.
The lower snowpack is strong and bonded.
