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

As new snow accumulates throughout the day the likelihood of triggering an avalanche will increase. Continually assess the changing conditions throughout the day.

Moderate

Avalanche Summary

No notable recent avalanches have been reported.

Please continue to post your observations and photos to the Mountain Information Network.

Snowpack Summary

New snow is burying a highly saturated snowpack from recent rain events. At higher elevations, the new snow overlies a melt-freeze crust. Treeline snow depths range from 100 to 150 cm.

Weather Summary

Thursday night

Cloudy and snow, 10 to 20 cm. Light southeast winds. 0 C at treeline. Freezing levels 1000 m.

Friday

Cloudy and heavy snow, 30 to 50 cm. Moderate south winds. 0 C at treeline. Freezing levels 1200 m.

Saturday

Cloudy and snow, 5 to 10 cm. Light southerly winds, with strong gusts. 0 C at treeline. Freezing levels 1000 m.

Sunday

Mostly cloudy, with no precipitation. Light south winds. -5 C at treeline. Freezing levels 700 m.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Watch for signs of slab formation throughout the day.

Avalanche Problems

Storm Slabs

Storm slabs will build with the forecasted heavy snow. New snow may take some time to bond to the underlying crusts.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely - Very Likely

Expected Size: 1 - 2.5

Loose Wet

The snowpack at lower elevations remains slurry and saturated. As the snowpack approaches its melting point it will result in a loss of cohesion.

Aspects: All aspects.

Elevations: Below Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
