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

Avoid avalanche terrain. New snow and wind will likely result in a natural avalanche cycle.

Confidence

High

Avalanche Summary

We suspect that a natural avalanche cycle will take place on Sunday.

Snowpack Summary

Another  significant storm will further saturate the snowpack at lower elevations. At higher elevations new snow accompanied by southerly winds will form storm and wind slabs.

A thick crust exists below recent storm snow at higher elevations, below this the remainder of the snowpack is well settled.

Weather Summary

Saturday Night

Stormy with up to 35 cm of new snow expected at higher elevations. Strong southerly winds and freezing levels falling to 1400 m.

Sunday

Stormy with up to 70 cm of new snow expected at higher elevations. Strong southerly winds and freezing levels rising to 1700 m with the snowline around 1000 m.

Monday

Mostly cloudy with flurries bringing up to 5 cm of new snow at higher elevations. Light to moderate southerly winds and freezing levels rising to 1000 m.

Tuesday

Mostly cloudy with up to 20 cm of new snow possible at higher elevations. Moderate southwest winds and freezing levels rising to 1000 m.

Terrain and Travel Advice

  • Avoid all avalanche terrain during periods of heavy snowfall.
  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.

Avalanche Problems

Storm Slabs

New snow and wind will form reactive storm slabs with the largest being found on west through east aspects due to strong to extreme southerly winds. Strong winds mean that slabs may be found further down slope than expected.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Certain

Expected Size: 1.5 - 3

Loose Wet

At lower elevations, where precipitation is more likely to fall as rain, wet loose avalanches are likely. Avoid steep terrain where even small avalanches can have serious consequences.

Aspects: All aspects.

Elevations: Below Treeline.

Likelihood: Likely

Expected Size: 1 - 1.5
