Recent new snow coupled with east and southeast wind, is causing wind slab development in alpine and treeline terrain.

Avalanche Summary
There are no new avalanches to report. Expect to see wind slab activity increase in the coming days as the recent new snow gets redistributed into exposed lee terrain.
Snowpack Summary
10 - 20 cm of new snow has accumulated over a crust at most elevations. Below 1500 m surface snow is likely moist or wet.
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 cooler temperatures have likely helped to strengthen these layers, we will continue to monitor them for signs of reactivity.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Closely monitor how the new snow is bonding to the crust.
Problems
