Regions

South Coast Inland, Coquihalla, Harrison-Fraser, Manning, Stein.

Stick to more sheltered areas to find the best snow and avoid wind-loaded slopes.

Early season hazards continue to pose a threat and are lurking just below the surface.

Avalanche Summary

No new natural avalanches have been reported. There is a potential for rider-triggered avalanches. If you head out into the backcountry and please consider submitting a MIN report if you observe any avalanche activity and support your

Snowpack Summary

At around 1750 m the snowpack sits at 110 to 165 cm. The top layer of light snow ranges between 20 to 75 cm with greater amounts towards the west. This new snow continues to settle and is sitting on a melt-freeze crust. At the moment this layer is not producing avalanches. Down 80 to 90 cm there is a series of crust layers. The bond between these layers and the snow beneath them has been weak to moderate in strength. Near the ground, the snow is not bonding well due to early-season cold temperatures and shallow snow.

Early season hazards such as rocks and stumps still lurk below the surface. Below treeline and even into treeline elevations are still below the threshold for avalanches.

Weather Summary

Friday Night

Mostly cloudy, trace accumulation, winds southeast 20 km/h, temperatures -10 C at 1500 m.

Saturday

Mainly sunny, no accumulation, winds east 20 km/h, temperatures -5 to -10 C at 1500 m.

Sunday

Sunny with cloudy periods, no accumulation, winds northeast 20 km/h, temperatures -10 C at 1300 m with 0 to -5 C in the alpine due to a temperature inversion.

Monday

A mix of sun and cloud, no accumulation, winds northeast 15 to 20 km/h, temperatures -5 at 1500 m.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
