The best areas for riding may overlap with where the wind has deposited loose snow. Check for reactive pockets around ridgelines and lee features.
Summary
Confidence
Moderate
Avalanche Summary
No new avalanches have been reported.
Cornices are big, give them space both above and below, and expect large cornices to be fragile, especially with loading or daytime warming.
Snowpack Summary
Strong south winds quickly impacted fresh snow. Expect to find wind-pressed surfaces, deeper and more reactive pockets around ridgelines, and a widespread crust in wind-scoured areas and lower elevations. Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth.
In some areas, particularly in the Haines Summit, a weak layer of facets or surface hoar is buried 50-80 cm. This layer is unlikely to trigger from the weight of a rider, but concern exists with very large loads like cornice falls.
Weather Summary
Sunday Night
Mostly cloudy with isolated flurries, trace accumulation. Southwest ridgetop wind 30 to 60 km/h. Treeline temperature low -9 °C. Freezing level valley bottom.
Monday
Cloudy with flurries, up to 5 cm. South-southwest ridgetop wind decreasing to 20 to 40 km/h. Treeline temperature -5 °C. Freezing level valley bottom.
Tuesday
Partly cloudy and clearing, isolated overnight flurries. West ridgetop wind 10 to 30 km/h. Treeline temperature -4 °C. Freezing level valley bottom.
Wednesday
Mix of sun and cloud. Light and variable ridgetop wind. Treeline temperature -4 °C. Freezing level valley bottom.

Terrain and Travel Advice
- Closely monitor how the new snow is bonding to the crust.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Problems
Wind Slabs
Strong wind has quickly impacted any loose snow. Watch for deeper and more reactive deposits around ridges and lee features.
