Snowpack Summary
5-10 cm of snow may accumulate through the day Monday at upper elevations. Expect southwest winds to redistribute this into alpine and treeline lee terrain. This may be sitting on a hard crust on all aspects to at least 1600 m. Below, the snowpack is generally settled and well bonded.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Wind slabs may be poorly bonded to the underlying crust.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
