Regions

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

New snow and strong wind will build touchy storm slabs.

Make conservative choices and be very wary of exposure to overhead hazard.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.
  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are confident a natural avalanche cycle will begin shortly after the arrival of the incoming weather.

Avalanche Summary

On Thursday and Friday, several skier triggered, remote triggered, and natural size 1 to 1.5 wind slab avalanches were reported in the region. These all occured in alpine terrain.

On Tuesday, several size 1 to 1.5 wind slab avalanches were reported in the region. These avalanches were triggered naturally, by explosives, and by skiers.

Snowpack Summary

New snow falls on a variety of surfaces, including old wind slab on all aspects, facets, and exposed crust.

The early February crust/facet layer is down 30 to 75 cm.

Another widespread crust and facet layer from late January is buried 40 to 100 cm deep.

The mid and lower snowpack is well settled and strong.

Weather Summary

Saturday Night
Cloudy. 10 cm of snow. 40 km/h southeast ridgetop wind. Treeline temperature -4 °C.

Sunday
Cloudy. 15 to 20 cm of snow. 60 km/h south ridgetop wind. Treeline temperature -3 °C.

Monday
Mostly cloudy. 25 to 35 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -4 °C.

Tuesday
Mostly sunny. 1 cm of snow. 10 km/h west ridgetop wind. Treeline temperature -6 °C.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.

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.
