Avalanche Summary
There were a few skier triggered size 1 wind slab and dry loose avalanches reported from steep terrain on Monday.
Snowpack Summary
Roughly 20 cm of new snow, with some local hot spots closer to 30 cm has been incrementally building over a crust at most elevations. Lower elevation surface snow is likely moist or wet depending on recent freezing levels.
A layer of facets (and small surface hoar in some areas) is buried 30-60 cm deep and a layer of facets sitting on a crust is buried 80-100 cm deep. While previous warming and subsequent cooling have likely helped to strengthen these layers, we will continue to monitor them for signs of reactivity.

Terrain and Travel Advice
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Problems
Wind Slabs
New snow is being redistributed by south winds and may create fresh wind slabs in exposed lee terrain. Wind slabs from easterly winds may still be reactive.
