Regions

Sea To Sky, South Coast, Brandywine, Garibaldi, Homathko, Powell River, Spearhead, Tantalus, North Shore, Sasquatch, Sky Pilot, Tetrahedron.

Natural avalanches are likely.

Avoid exposure to avalanche terrain during periods of high hazard.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.
  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

Cornices continued to be controlled this week, with size 1 to 1.5 results. A few wet loose avalanches were reported in the last few days.

We expect avalanche activity to increase with the forecasted weather.

Snowpack Summary

30 to 45 cm of new snow is expected by the end of the forecast period on Tuesday. This new snow overlies a melt-freeze crust, moist snow, or isothermal conditions, depending on aspect and elevation.

The snowpack has undergone multiple warming and cooling cycles, forming a series of crusts with dense, rounded grains in between.

Weather Summary

Monday Night

Cloudy. 3 to 10 mm of precipitation as snow or rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Tuesday

Cloudy. 30 to 35 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1100 m.

Wednesday

Mix of sun and clouds. 10 to 15 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -5 °C.

Thursday

Mostly sunny. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Don't let storm day fever lure you into consequential 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.
