Recent storm slabs likely remain triggerable by riders on Tuesday. Tune into any signs of instability like cracking, whumphing or recent avalanches as indicators to back off into lower angle or less wind-loaded terrain.

Avalanche Summary
Over the weekend, explosives and ski cuts produced loose dry and soft slab avalanches up to size 1. On Saturday a few small to medium sized storm slabs were triggered by skiers, as reported in this MIN from Sky Pilot.
Snowpack Summary
50-80 cm of heavy, moist snow appears to be bonding well to a hard melt-freeze crust that exists on all aspects up to 1500 m and to the mountain tops on sun-exposed slopes.
A few other melt-freeze crusts are found in the top 100 cm of the snowpack but appear to be progressively bonding.
The remainder of the snowpack is well-bonded.
Terrain and Travel
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
- Avoid freshly wind loaded terrain features.
- Avoid steep, unsupported slopes.
