The new snow will bond poorly to underlying layers, with deeper slabs expected on northeast aspects due to wind loading.
The incoming storm is driving the avalanche danger.

The new snow will bond poorly to underlying layers, with deeper slabs expected on northeast aspects due to wind loading.
New storm slabs will form on Friday and Saturday. Human-triggered avalanches will be likely on most steep slopes and natural avalanches are possible on wind-loaded slopes.
Flurries on Saturday will bring the storm totals to 15 to 25 cm, with deeper deposits in wind-loaded areas. The new snow will likely bond poorly to the old snow surfaces, which includes melt-freeze crusts on sun-exposed slopes, large surface hoar or facets on shaded slopes, and wind-affected snow in exposed terrain at ridgelines.
The lower snowpack is strong and bonded. Treeline snow depths average 100 to 150 cm.
