Look for signs of instability and be prepared to step back.
There is some uncertainty in how the snowpack will react to above freezing temperatures in the alpine.
Summary
Confidence
Avalanche Summary
No new avalanches have been reported in the past few days.
Snowpack Summary
Previous southwesterly winds have redistributed recent new snow into wind slabs. The snow surface may become moist on steep south facing slopes in the afternoon.
A layer of surface hoar may be found down 10 to 30 cm in sheltered terrain.
A thick melt-freeze crust is found down 50 to 100 cm. this layer is not currently a concern but may be after being impacted by warm temperatures for a prolonged period.
Weather Summary
Tuesday Night

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
- Be alert to conditions that change with elevation and sun exposure.
- Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
Problems
Wind Slabs
Southwest winds have formed reactive wind slabs in lee terrain. These slabs could remain reactive to riders where they overlie facets or surface hoar.
Aspects: North, North East, East, North West.
Elevations: Alpine, Treeline.

Loose Wet
Solar input and an above freezing layer could result in wet loose avalanches in the alpine.
Aspects: South East, South, South West.
