Avalanche Summary
No new avalanches have been reported since the rain event earlier this week.
If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network.
Snowpack Summary
Approximately 30 cm of recent snow now blankets a melt-freeze crust. Pockets of deeper wind-deposited snow can be found at treeline and above. In wind-sheltered terrain, a layer of surface hoar may be buried by Saturday's snowfall.
Overall, the snow depth remains relatively shallow, with numerous hazards present at or just below the snow surface across all elevations.

Terrain and Travel Advice
- Avoid areas where the snow feels stiff and/or slabby.
- Keep in mind the crust offers an excellent bed surface for avalanches.
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
