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

Storm slabs are building at treeline and above.

Use conservative terrain selection during periods of rapid loading from new snow or rain.

Confidence

Moderate

Avalanche Summary

Reports have been very limited during the recent stormy period. Several wet loose avalanches were reported across the region over the past few days, generally in the small (size 1-1.5) range.

We expect with further snowfall accumulating overnight and through Saturday that storm slabs will be reactive.

Snowpack Summary

Over 100 mm of precipitation has fallen in parts of the region over the past few days. Freezing levels have fluctuated, with periods of rain reaching mountaintops. Temperatures are expected to drop, and 30 to 50 cm of fresh snow is anticipated above 1000 m overnight and through Saturday. The highest precipitation is forecast for the North Shore. These conditions will create reactive storm slabs at upper elevations, with deeper and more sensitive deposits forming on northerly slopes due to strong southerly winds. At lower elevations, expect a moist or wet snowpack.

Weather Summary

Friday Night

Cloudy, with 15 to 25 cm of snow above 1000 m, potential rain below. Highest amounts for the North Shore. 35 to 45 km/h south ridgetop winds. Treeline temperature -3 °C. Freezing level around 1400 m, dropping to 1000 m.

Saturday

Cloudy with 15 to 25 cm of snow above 1000 m, potential rain below. Highest amounts for the North Shore. 35 km/h south ridgetop winds. Treeline temperature -2 °C. Freezing level rising to 1300 m.

Sunday

Sunny. 25 to 35 km/h southeast ridgetop winds. Treeline temperature +2 °C. Freezing level rising to 1800 m.

Monday

Cloudy with 15 to 30 cm of snow. 30 to 40 km/h variable ridgetop winds. Treeline temperature -3 °C. Freezing level around 1400 m.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Keep in mind that the high density of wet avalanches can make them destructive.
  • Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.

Avalanche Problems

Storm Slabs

30 to 50 cm of new storm snow may accumulate at treeline and above by Saturday afternoon. Expect to find deeper deposits due to wind on northerly slopes.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2.5

Loose Wet

Wet loose avalanches are possible where precipitation falls as rain or the upper snowpack is moist or wet.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Likely

Expected Size: 1 - 2
