Tune in to the changing conditions of elevation, aspect, and time of day.
Be cautious in wind-affected terrain and avoid steep sun-exposed slopes and overhead hazard when air temperature is warm or the sun is strong.

Avalanche Summary
Around Mount Cain on Friday, our field team observed small (size 1.5) dry loose avalanches occurring when new snow was exposed to daytime warming and solar input.
If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.
Snowpack Summary
In terrain above 1600 m, 10-30 cm of preserved dry snow has been affected by recent easterly wind. A crust can be found on the surface below 1600 m.
The mid and lower snowpack are well consolidated and strong.

Terrain and Travel Advice
- Be carefull around freshly wind loaded features.
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
- As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
Problems
Wind Slabs
Easterly winds are expected to have redistributed 10-30 cm of recent storm snow into fresh, reactive wind slabs in exposed areas in the alpine and treeline.
Aspects: North, South East, South, South West, West, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Warm temperatures and strong sun may create wet loose avalanche in steep south-facing terrain.
Keep in mind, that wet loose avalanches may start small but they can grow and push you into dangerous terrain.
Aspects: South East, South, South West, West.
Elevations: All elevations.
