Regions: Brandywine, Garibaldi, Harrison-Fraser, Homathko, Powell River, Sasquatch, Sea To Sky, Sky Pilot, Spearhead, Stave, Tantalus.

Isolated features at higher elevations may hold enough snow to be above threshold for avalanches but early season hazards are more concerning.

Confidence

Moderate

Avalanche Summary

No avalanches have been reported in the past few days. Please consider filling out a MIN report if you are out in the backcountry.

Snowpack Summary

Surface conditions are highly variable. During the day the snow surface will likely become moist at treeline and below. Above the freezing level a layer of surface hoar exists on sheltered features, . Exposed terrain is generally wind effected.

A crust buried on November 22 is down 10 to 30 cm.

Above about 1600 m, snowpack height ranges from 50-100 cm, increasing with elevation and deepest on the west side of Hwy 99. The base of the snowpack is well consolidated and bonded to the ground and glacial ice.

Weather Summary

Sunday Night

Mostly clear skies with no new snow expected, 10 to 20 km/h southwest alpine wind with the potential for outflow wind at lower elevations, freezing level around 1000 m.

Monday

Mostly clear skies with no new snow expected, 5 to 20 km/h southwest alpine wind, freezing level around 2100 m.

Tuesday

Mostly clear skies with no new snow expected, 5 to 20 km/h southwest alpine wind, freezing level around 2300 m.

Wednesday

Mostly clear skies with no new snow expected, 5 to 10 km/h ridgetop wind, treeline temperature -6°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Avalanche Problems

Wind Slabs

Small wind slabs may be found in the alpine. These slabs are likely only triggereble where they overlie facets.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1 - 1.5
