Avalanche Forecast
Sea To Sky
Successive moderate storms will keep danger elevated, particularly in steep, wind-affected terrain. If the 24 hour snow amounts exceed 25 cm, bump avalanche danger up by one rating.

Travel and Terrain Advice
- Avoid steep lee and cross-loaded features
- Use ridges or ribs to avoid pockets of wind loaded snow.
Avalanche Summary
Ski cutting produced soft slab avalanches up to size 1.5 in recent storm snow at treeline and alpine elevations on Tuesday. Similar results would be expected for Thursday.
Snowpack Summary
Approximately 30-40 cm new snow now sits on top of a rain crust (or multiple crusts) that formed during the recent wet weather. Strong winds have blown snow around in exposed areas creating drifts and scoured areas. Snowpack depths are typically around 140 cm in sheltered treeline locations, although deeper (and shallower) spots certainly exist on account of the strong winds.
Weather Forecast
Thursday: 10-15 cm new snow expected with freezing levels around 1000 m. Strong southwesterly winds.
Friday: 10-15 cm new snow expected with freezing levels around 1000 m. Moderate southwesterly winds.
Saturday: 5 cm new snow expected with freezing levels around 900 m. Moderate southwesterly winds.
