Regions

Vancouver Island, East Island, North Island, South Island, West Island.

Storm slabs are expected to be most reactive in wind affected terrain at upper elevations.

Use small, low consequence slopes to test the bond of the new snow.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported on Saturday.

NOTE: Observations are currently very limited in this region.

Snowpack Summary

Forecast snow and southerly wind may form fresh storm slabs above 1000 m, rain below. Below the new snow is a thick crust at upper elevations and a rain soaked snowpack at lower elevations.

The snowpack is strong and well-bonded, but melting quickly at lower elevations.

Weather Summary

Sunday Night

Snow, 10 to 20 cm above 1000 m, rain below. 20 to 30 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1300 m.

Monday

Snow, 15 to 30 cm above 1000 m. 20 to 30 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1100 m.

Tuesday

Cloudy with flurries, 5 to 10 cm snow. 10 to 20 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 1400 m.

Wednesday

Mostly cloudy with isolated flurries, 0 to 5 cm snow. 10 to 20 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1300 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Use small, low consequence slopes to test the bond of the new snow.

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.
