Moderate
Avalanche Summary
Saturday, several natural storm slab avalanches up to size 2 were reported. The new snow is poorly bonded to the old snow surface, and many size 1 human-triggered loose dry avalanches in steep areas were also reported.
Storm slabs will continue to form on Sunday. Human-triggered avalanches will be likely on steep slopes, and natural avalanches could be 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 Sunday 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
- It's a good day to make conservative terrain choices.
- Choose simple, low-angle terrain without steep convex rolls.
- Avoid freshly wind-loaded terrain features.
- 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.
