Our neighbours to the North (BNP) are seeing increased natural and skier accidental activity up to size 3. Although they have more snow in there region we are all dealing with very similar snowpack structure. Be cautious out there!

Snowpack Summary
Treeline and alpine windslabs continue to be the main avalanche concern in terms of "triggerability". They are improving with the the relatively warm temperatures, but still expect to find reactive pockets in steep and/or convex terrain. In terms of consequence, the dreaded Nov 5 facets still have a firm grip on the low probability/high consequence title. Some of our neighbours to the west have seen failures on this layer, which suggest loading is a critical factor in when this layer will fail.
Weather Summary
Trace amounts of snow tonight and tomorrow. Winds will finally let up a bit and be Northwest 15km/h. The sky's will remain cloudy with partial sunny periods. Day time highs will be slightly cooler with -13

Terrain and Travel Advice
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Be aware of the potential for surprisingly large avalanches due to deeply buried weak layers.
Problems
Wind Slabs
Open slopes at treeline and alpine areas look plump and ready for a trigger. Low angle terrain is still key.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Deep Persistent Slabs
Thin areas are where this layer will be easiest to trigger. Be thinking about wide propagations as the snowpack above is more cohesive than before.
Aspects: All aspects.
Elevations: Alpine, Treeline.
