Travel in avalanche terrain is not recommended. Avalanches in the new snow are very likely.

30 to 50 cm of new snow will cause large avalanches on wind-loaded slopes, touchy slabs on steep slopes, and fast-moving loose avalanches.
New storm slabs will form on Friday and Saturday. Human-triggered avalanches will be very likely on steep slopes, and natural avalanches are expected anywhere with more than 30 cm of new snow.
Ongoing snow and wind will build reactive storm slabs over the weekend, with storm totals reaching 30 to 50 cm by Saturday afternoon. The new snow will 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.
