With freezing levels gradually decreasing natural avalanche activity will likely also decrease. Human-triggered avalanches remain possible.
Summary
Confidence
Avalanche Summary
Observations over the weekend were limited, however, we suspect recent widespread wet loose and wet slab avalanche activity.
Snowpack Summary
As sunny days and high freezing levels continue, more of the upper snowpack will get moist or wet. The snowpack remains generally unstable.
80 to 120 cm below the snow surface, a weak layer of faceted snow may exist sitting atop a crust on all but high north aspects.
The mid and lower snowpack is generally settled and strong.
Weather Summary
Monday Night
Sunny. 0 to 20 km/h southwest ridgetop wind. Treeline temperature 8 °C. Freezing level 3000 m.
Tuesday
Cloud building throughout the day. 10 to 30 km/h southwest ridgetop wind. Treeline temperature 6 °C. Freezing level 2500 m.
Wednesday
Mostly cloudy. 20 to 40 km/h south ridgetop wind. Treeline temperature 2 °C. Freezing level drops to 1300 m by the end of the day.
Thursday
Cloudy with 0 to 5 cm of snow at higher elevations. Freezing level 1500 m. 0 to 20 km/h south ridgetop wind. Treeline temperature 0 °C.

Terrain and Travel Advice
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- Avoid sun exposed slopes, especially if snow surface is moist or wet.
- Avoid exposure to overhead avalanche terrain, avalanches may run surprisingly far.
- Good day to make conservative terrain choices.
Problems
Loose Wet
Expect wet loose avalanche activity to persist, especially late in the day due to warming temperatures and solar effect.
These may step down to deeper layers resulting in larger-than-expected avalanches.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
Down roughly 80-150 cm from the surface a weak layer of faceted snow and spotty surface hoar may persist atop a firm crust.
Aspects: All aspects.
Elevations: Alpine, Treeline.
