Avalanche Summary
Despite the lack of reports, we suspect a natural avalanche cycle to have occurred during the peak of the warming event (Monday night).
If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network
Snowpack Summary
A widespread thick crust continues to form in the aftermath of Monday's warm, wet weather. This crust should provide a bridge over any previous layers of concern deeper in the snowpack.

Terrain and Travel Advice
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Snow is accumulating at higher elevations despite lower elevations being almost snow free
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
Problems
Storm Slabs
Be on the look out for fresh storm and wind slabs anywhere that a thick crust on the surface doesn't exist.
