Regions

Sea To Sky, Brandywine, Garibaldi, Homathko, Spearhead.

Be sure that recent snowfall amounts in your location haven't exceeded the expected amounts before venturing into larger terrain.

New snow may sit atop weak surface hoar crystals in areas.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported in this region.

If you do go into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Roughly 20 to 30 cm of recent snow has been redistributed by strong southerly winds in the alpine. At treeline and above in wind-sheltered terrain, the new snow sits atop variable old surfaces, including large surface hoar crystals. In wind-exposed terrain and areas below treeline the new snow sits atop a widespread, thick crust.

The mid and lower snowpack remains well-bonded with no layers of concern.

Weather Summary

Sunday Night

Cloudy with 5 to 15 cm of snow. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Monday

Sunny. 10 to 30 km/h northeast ridgetop wind. Treeline temperature -4 °C.

Tuesday

Sunny. 10 to 20 km/h northeast ridgetop wind. Treeline temperature -7 °C.

Wednesday

Sunny. 30 to 50 km/h northeast ridgetop wind. Treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Be aware of the potential for larger than expected storm slabs due to the presence of buried surface hoar.
  • The new snow may require another day to settle and stabilize.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
