Storm snow may take time to bond with the rain crust or surface hoar below.
Be cautious on steep slopes -fresh wind slabs may form at higher elevations

Avalanche Summary
Natural avalanche activity was observed throughout the storm to size 2. Explosive control on Sunday also produced size 2 avalanches.
MIN users noted cracking in the storm snow on Sunday, indicating reactivity still remains.
Snowpack Summary
Around 30 cm of wind affected storm snow sits over a mix of crusts, surface hoar in wind-sheltered terrain, and hard wind-affected surfaces. Low elevations received mostly rain while higher elevations received wet snow or mixed precipitation.
Check out this MIN report for a great overview of conditions in Orca Bowl, and this MIN report covers conditions in the Tunnel Mountain area.
The middle of the snowpack is generally expected to be well-settled and stable. Total snow depths vary from 100 to 150 cm at treeline.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Closely monitor how the new snow is bonding to the old surface.
Problems
Wind Slabs
Wind slabs likely remain reactive to human triggers. In sheltered areas, where rain did not affect the snowpack preserved surface hoar may be present, increasing reactivity.
