High
Avalanche Summary
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.
Snowpack Summary
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.

Terrain and Travel Advice
- Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
- Only the most simple non-avalanche terrain with no overhead hazard is appropriate at this time.
- Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
Problems
Storm Slabs
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.
