Regions: Garibaldi, North Shore, Powell River, Sasquatch, Sky Pilot, South Coast, Stave, Tetrahedron.

Continually assess new snow amounts throughout the day. If more than 20 cm of new snow is observed expect reactive storm slabs.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in this region over the past few days.

We expect rider triggerable storm slabs will form throughout the day on Saturday.

Snowpack Summary

Up to 25 cm of new storm snow is expected with southeast winds. This new snow will fall over a crust on solar aspects and at lower elevations, it may not bond well.

In general the mid and lower snowpack is well settled and bonded.

Weather Summary

Friday Night

Cloudy with up to 10 cm of new snow expected. Light southerly winds and a low of -5°C at 1500 m.

Saturday

Cloudy with flurries bringing up to 15 cm of new snow. Moderate southeast winds and a high of -3°C at 1500 m, freezing level rising to 1100 m.

Sunday

Mostly cloudy with light flurries bringing around 5 cm of new snow. Moderate southeast winds and freezing levels rising to 1200 m.

Monday

Stormy with up to 80 mm of precipitation falling as snow at treeline and above. Strong southerly winds and freezing level rising to 1700 m.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
  • Closely monitor how the new snow is bonding to the crust.

Avalanche Problems

Storm Slabs

Reactive storm slabs could form throughout the day. The largest and most reactive slabs will likely be found on northerly aspects. Larger than expected storm slabs are possible on southerly slopes and at lower elevations due to the underlying crust.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely - Very Likely

Expected Size: 1 - 2
