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

New snow and wind are forming fresh, reactive slabs.

Stick to lower-angled conservative terrain and be mindful of overhead hazard.

Confidence

High

Avalanche Summary

No new avalanches have been observed in the past few days. Conditions will change on Friday as new snow and wind form fresh, reactive slabs.

Snowpack Summary

Up to 30 cm of new snow overlies a thin crust at treeline and below and into the alpine on sunny slopes. Surface hoar may be preserved in sheltered areas. At lower elevations, a moist snow surface can be expected where precipitation falls as rain.

The mid and lower snowpack is well consolidated, with several well-bonded crusts scattered throughout.

Snow depth has been reported as 330 cm at 1700 m, tapering quickly at lower elevations below treeline.

Weather Summary

Thursday Night

Cloudy with 10 to 20 cm of new snow. 30 to 70 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level drops to 1000 m.

Friday

Cloudy with up to 10 cm of new snow. 30 to 70 km/h northwest ridgetop wind. Treeline temperature -4 °C.

Saturday

A mix of sun and cloud with isolated flurries. 15 to 40 km/h northwest ridgetop wind. Treeline temperature -4 °C.

Sunday

Mostly sunny with valley cloud. 15 to 40 km/h north ridgetop wind. Treeline temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • It's a good day to make conservative terrain choices.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.

Avalanche Problems

Storm Slabs

New snow and wind will form fresh slabs that are expected to be deepest and most reactive in wind-loaded terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2

Loose Wet

Wet loose avalanches may occur on steep slopes where rain has weakened the upper snowpack.

Aspects: All aspects.

Elevations: Below Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2
