The avalanche problem should be easy to manage right now, just avoid wind exposed terrain where wind slabs are actively forming. Bonus, by seeking out wind sheltered terrain you will also find the best riding conditions.
Summary

SATURDAY: Broken cloud cover, freezing level at valley bottom, light to moderate south wind, 1 to 5 cm of snow possible.
Avalanche Summary
There has been almost no recent reported avalanche activity aside from the formation of small wind slabs immediately lee of ridge crest.
Snowpack Summary
Continued southwest wind has resulted in the formation of fresh wind slabs in exposed terrain at higher elevations. Terrain features immediately lee of ridgecrest should be especially suspect.
A subtle and aspect-dependant new layer of surface was reported on the surface in the White Pass area on Sunday. This will be something to track as forecast flurries bury it this week.
A buried crust formed in early December can be found 60-100 cm below the surface, but most reports suggest the snow is quite well-bonded to this crust. There was one observation last week where facets were found above the crust, but that appears to be an anomaly rather than the norm.
The lower snowpack is strong around White Pass, but there is potential for a generally thinner and weaker snowpack structure to exist in inland areas such as the Wheaton Valley.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Be aware of highly variable recent wind loading patterns.
- Sheltered slopes at lower elevations will offer the best riding.
Problems
Wind Slabs
Watch for new wind slabs in wind-exposed terrain. Forecast light flurries and elevated winds are likely to from fresh slabs on a continuous basis for the next few days.
