While the likelihood of triggering a deep persistent layer may be decreasing, it is very difficult to predict where you will or will not trigger a large avalanche.
Continue to take a conservative approach while traveling in avalanche terrain.

Avalanche Summary
No recent avalanches have been reported in the region.

Snowpack Summary
Roughly 10 cm of low-density snow since the weekend overlies a generally well-settled upper snowpack. The mid and lower snowpack consists of loose facets, with a significant weak layer of large facets and a crust down 80 to 120 cm from the surface. The snow below this weak layer is generally weak and unconsolidated.
Treeline snow depths are roughly 140 to 160 cm.
Weather Summary
Monday night
Cloudy with clear periods, 2 to 5 cm. Light southwest ridgetop winds. Treeline temperatures -5 to -10 C.
Tuesday
A mix of sun and cloud, no precipitation. Light west ridgetop winds. Treeline temperatures -5 to -10 C.
Wednesday
A mix of sun and cloud, no precipitation. Light ridgetop winds. Treeline temperatures -5 to -10 C.
Thursday
A mix of sun and cloud, no precipitation. Light to moderate ridgetop winds. Treeline temperatures -5 to -10 C.

Terrain and Travel Advice
- Uncertainty is best managed through conservative terrain choices at this time.
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- Don't let the desire for deep powder pull you into high consequence terrain.
Problems
Deep Persistent Slabs
A weak layer near the base of the snowpack remains a concern despite lack of recent avalanche activity. Human triggering of this layer remains possible, especially in shallow areas with variable snow depths.
Aspects: All aspects.
