Regions: Brandywine, Garibaldi, Homathko, Sea To Sky, Sky Pilot, Spearhead, Tantalus.

While avalanche hazard is improving with cooling temperatures, human-triggered persistent slab avalanches remain a concern in areas not capped by a thick surface crust.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported in the region.

If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. We read every report!

Snowpack Summary

A dusting of snow overlies a crust capping a moist upper snowpack on all but north-facing terrain above 2000 m.

A significant crust/facet layer is buried 100 to 250 cm deep. This layer was the culprit in many very large avalanches through the extended warm period. Uncertainty remains around how long this layer will remain triggerable as temperatures cool.

Below the crust, the snowpack is well settled.

Weather Summary

Sunday night

Increasing cloud. 10 to 20 km/h variable ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Monday

Cloudy with up to 5 cm of snow. 10 to 20 km/h variable ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Tuesday

Cloudy with 5 to 10 cm of snow. 10 to 20 km/h variable ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Wednesday

Cloudy with 10 to 15 cm of snow. 40 to 70 km/h southeast ridgetop wind. Treeline temperature -1 °C. Freezing level 1400 m.

Terrain and Travel Advice

  • Conditions may have improved, but be mindful that deep instabilities are still present.
  • Use caution on large alpine slopes, especially around thin areas that may propagate to deeper instabilities.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Avalanche Problems

Persistent Slabs

This weak layer has slowly been gaining strength however concern remains for human-triggering the layer on sheltered north aspects above 2000 m. If triggered avalanches will be large and destructive.

Aspects: North, North East, North West.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3.5
