Regions

South Coast, Powell River, North Shore, Tetrahedron.

Fresh snow may not bond well to the crust below. And also just barely cover lower elevation hazards.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported.

If you head into the backcountry by any method of travel, please consider submitting observations and/or photos on the Mountain Information Network.

Snowpack Summary

30-50 cm of fresh snow accumulated by Saturday morning. Remote telemetry stations recorded over 100mm/60cm in 24 hours!

Recent snow covers a crust and well-settled snowpack in the alpine and upper treeline. Strong SW wind may have redistributed loose snow to lee features. This recent storm has brought winter to the North Shore Mountains, however, lower-elevation areas may remain below the threshold for avalanches.

Weather Summary

Saturday Night

Partly cloudy with no precipitation. Northwest ridgetop wind to 20 km/h. Treeline low around -8 °C.

Sunday

Mostly sunny with no precipitation. Northwest ridgetop 5-15 km/h. Treeline low around -6 °C.

Monday

A mix of sun and clouds. No precipitation. Increasing southwest ridgetop wind. Treeline low around -5 °C.

Tuesday

Snowing, 30-70 cm starting late Monday. Strong southwest ridgetop wind. Treeline low around -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be especially cautious as you transition into wind affected terrain.
  • Closely monitor how the new snow is bonding to the crust.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

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.
