Watch for conditions changing throughout the day. Storm slabs will become more reactive to human-triggering as snow accumulates.

Avalanche Summary
No recent avalanches have been reported in the region.
If you do head into the backcountry please consider submitting observations and/or photos on the Mountain Information Network.
Snowpack Summary
+15 cm of wind affected storm snow covers a thick melt-freeze crust at all elevations. The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.
Overall, the snow depth remains relatively shallow, creating challenging travel conditions and numerous hazards at or just below the snow surface across all elevations.
Weather Summary

Terrain and Travel Advice
- Storm slab size and sensitivity to triggering will likely increase through the day.
- Closely monitor how the new snow is bonding to the crust.
- 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
Use caution in windloaded terrain where pockets of storm snow are deeper, cohesive and may be reactive to human-triggering.
