Avalanche Summary
No new avalanches have been reported, but observations have been very limited in this region.
We expect that large, natural, and human-triggered avalanches will remain triggerable.
If you go into the backcountry, please consider submitting a Mountain Information Network (MIN) post.
Snowpack Summary
Between 50 and 90 mm has fallen as snow in high elevation areas, or as rain below treeline, in the past 24 hours.
At upper elevations, strong to extreme winds have formed deeper storm slabs on northeast through northwest-facing slopes.
Expect a rain-saturated snowpack or lack of snow at lower elevations.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
Problems
Wind Slabs
Reactive wind slabs are expected to exist at all elevations where the storm delivered snow. Watch for lee slopes.
Older, deeper, storm slabs formed earlier in the week may still exist, meaning large avalanches could be triggered.
Aspects: North, North East, East, South East, West, North West.
Elevations: All elevations.
