A widespread surface crust makes for generally safe conditions. Scale back your terrain choice as the surface snow deteriorates and weakens with daytime warming and sunny conditions.
Summary
Confidence
High
Avalanche Summary
Natural wet loose avalanche activity continues to be reported, primarily below treeline and on steep south-facing terrain.
The widespread, natural avalanche cycle reported over the weekend appears to have ended.
Snowpack Summary
A widespread melt-freeze crust exists on the surface. Expect the crust to deteriorate, and weaken at lower elevations and on south-facing slopes throughout the day.
Various weak layers, including crusts, facets, and/or surface hoar exist approximately 90 and 180 cm below the surface.
Weather Summary
Tuesday Night
Partly cloudy with 0 to 2 cm of snow. 10 to 30 km/h east ridgetop winds. Treeline temperature -1 °C. Freezing level 1400 m.
Wednesday
Mostly sunny. 10 to 30 km/h east ridgetop wind. Treeline temperature -3 °C. Freezing level 1200 m.
Thursday
Mostly sunny. 0 to 20 km/h east ridegtop wind. Treeline temperature -3 °C. Freezing level 1100 m.
Friday
Mostly sunny. 20 to 40 km/h northeast ridgetop wind. Treeline temperature -9 °C. Freezing level 500 m.

Terrain and Travel Advice
- Keep in mind that human triggering potential persists as natural avalanching tapers off.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
Problems
Loose Wet
Wet loose avalanche likelihood will increase throughout the day with daytime warming and sunny conditions, particularly on steep south-facing terrain.
Aspects: South East, South, South West, West.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
Persistent slab avalanches remain possible, especially later in the day as the surface snow deteriorates, and weakens from daytime warming and solar effect.
Aspects: All aspects.
Elevations: All elevations.
