Watch for conditions changing throughout the day. Ssmall rider triggerable wind slabs may form as a result of new snow and wind.

Avalanche Summary
No recent avalanches have been reported in the region, however there are currently very few field observations.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
New snow with southerly winds will likely form wind slab on lee features at upper elevations. A crust exists on or near the surface on all aspects treeline and below and on steep south aspects in the alpine. The upper snowpack is generally well settled with no current layers of concern.
The mid-pack generally contains two separate layers of surface hoar. At lower elevations, a melt-freeze crust may exist between the two surface hoar layers.
The current snowpack has considerable variation in structure and depths across the region.

Terrain and Travel Advice
- Surface hoar distribution is highly variable. Avoid generalizing your observations.
- Start with conservative lines and watch for clues of instability.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Problems
Persistent Slabs
Surface hoar layers in the mid pack are still a concern where a significant crust isn't found near the surface.
