Regions

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

New snow and wind loading have formed reactive storm slabs, especially on north through east-facing slopes.

It's a good day to stick to conservative terrain sheltered from the wind.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.
  • We are uncertain due to the timing of the incoming weather system.

Avalanche Summary

On Monday, the region saw a widespread natural avalanche cycle up to size 3, which likely occurred during the storm.

Avalanche danger may spike on Wednesday afternoon with new snow and strong winds.

Snowpack Summary

Up to 60 cm of new storm snow has blanketed the region. This sits on a variety of surfaces, including old wind slab on all aspects, facets, and exposed crust. Expect the potential for a poor bond at the storm snow interface.

The early February crust/facet layer is down approximately 100 cm.

Another widespread crust and facet layer from late January is buried 120 to 160 cm deep.

The mid and lower snowpack is well settled and strong.

Weather Summary

Tuesday Night
Mostly cloudy. 1 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Wednesday
Cloudy. 10 to 20 cm of snow. 50 gusting to 80 km/h west ridgetop wind. Treeline temperature -5 °C.

Thursday
Cloudy. 10 to 25 cm of snow. 60 gusting to 100 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Friday
Mostly cloudy. 5 to 10 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Strong wind is building wind slabs farther downslope than usual.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Start with conservative terrain and watch for signs of instability.

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.
