Avalanche Summary
On Sunday, there were several small avalanches reported, generally thin storm slabs or loose wet avalanches, as well as natural avalanches triggered by sun.
On Saturday, there were several small and large (size 2) skier accidental storm slab avalanches reported. Mostly in steep terrain on east to north aspects in the alpine.
North of Revelstoke there was also one large (size 3) persistent slab avalanche triggered by a helicopter landing at 2300 m on a northeast aspect.
Snowpack Summary
Freezing levels are staying very elevated, but it's clouding over. Expect the surface to remain moist until the freezing level really drops on Wednesday.
20 to 40 cm of recent snow snow sits on surface hoar crystals that overly soft or wind affected snow on northerly alpine terrain or a hard melt-freeze crust elsewhere.
Weak faceted grains above a hard crust that formed in early February are buried around 100 to 150 cm deep. The layer is strengthening and is currently dormant.
The remainder of the snowpack is settled.
Weather Summary
Monday Night
Mostly clear. No new snow expected. Light to moderate southwest ridgetop wind. Treeline low around 2 °C.
Tuesday
Partly cloudy. No new snow expected. Light to moderate southwest ridgetop wind. Treeline high around 6 °C. Freezing level between 2500 and 3000 m.
Wednesday
Mostly cloudy. Light rainfall turning to snow as the freezing level drops. 5-10 cm possible at high elevations in some areas. Strong southwest ridgetop wind overnight, easing to light through the day. Treeline temperature around -5 °C.
Thursday
Mostly cloudy. 0-3 cm of snow expected above 1000 m. Light northeast ridgetop wind. Treeline temperature around -4 °C.

Terrain and Travel Advice
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Approach lee and cross-loaded slopes with caution.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Problems
Wind Slabs
Moderate west and northwest winds have likely formed deeper, more reactive pockets of snow in lee terrain features near ridgetop. These slabs could rest on weak layers on northerly aspects and a hard crust elsewhere.
Aspects: North East, East, South East, South, South West.
Elevations: Alpine, Treeline.
