Stay vigilant of changing conditions, especially when the March sun comes out.

Carefully manage your exposure to overhead hazards during periods of sun.

Avalanche Summary

Evidence of natural and human-triggered avalanches (wind and storm slabs) from this stormy weekend is still being reported in the Sky Pilot area.

Small sluffs were easily triggered by skiers on steep northerly slopes while unstable wet snow was observed on southerly slopes due to solar radiation throughout the region.

Thanks for sharing your observations via the MIN if you are going out into the backcountry.

Snowpack Summary

The region received 20 to 25 cm of recent snow this past weekend, totaling 120 cm of recent storm snow, which is settling out rapidly. Unsettled conditions have brought up to 35 cm of new snow in localized areas.

At upper elevations, strong winds have formed deeper deposits of wind-transported snow. At treeline and below, the new snow sits above a crust. The snow reportedly has a good bond to the underlying crust. Southerly slopes were affected by the sun, resulting in heavy wet snow, especially at lower elevations.

Below this, the snowpack is well-settled and strong.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Be careful as you transition into wind-affected terrain.
  • Wind slabs are isolated, but may remain reactive.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

Avalanche Problems

Loose Wet

Small wet loose avalanches will be likely on steep sun-exposed slopes. Avoid overhead hazard from steep sunny faces during the warmest parts of the day.

Aspects: South East, South, South West, West.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5

Wind Slabs

Recent snow and wind have created fresh wind slabs. Use caution as you transfer into wind-affected terrain, as these slabs can still be triggered by riders.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
