Regions

South Coast, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron, Coquihalla, Harrison-Fraser, Manning, Skagit.

While lower elevations remain mostly bare, accumulating snow in the alpine may be creating deeper pockets that could produce early-season avalanches.

Confidence

Low

Avalanche Summary

No avalanches have been reported. However, field observations are extremely limited in the early season.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

At upper elevations, 5 to 15 cm of recent snow is being redistributed by light to moderate easterly winds.

We suspect there is up to 80 cm of snow in some alpine terrain.

At higher elevations, a thick crust likely exists just beneath the new snow or at the surface in areas that received less recent snow.

Snow depth tapers rapidly with elevation.

Weather Summary

Thursday Night

Mostly cloudy. 1 to 3 cm of snow at treeline. 30 km/h northeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1500 m.

Friday

Sunny. 20 km/h northeast ridgetop wind. Treeline temperature 0 °C. Freezing level 1600 m.

Saturday

Partly cloudy. 0 to 2 cm of snow at treeline. 10 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Sunday

Mix of sun and cloud. 10 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • If it's deep enough to ride, it's deep enough to slide (avalanche).
  • Avoid areas where the snow feels stiff and/or slabby.
  • Be cautious of buried obstacles, especially below treeline.

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.
