Regions

South Coast, North Shore, Sasquatch, Sky Pilot.

Assess for drifts and stiff wind slabs in exposed terrain. Cohesive slabs formed on the surface likely sit on a weak layer of feathery surface hoar crystals over a crust.

Confidence

Avalanche Summary

No new avalanches have been reported in the past few days.

If you head out into the mountains, please share your photos or observations on the Mountain Information Network. Your information helps us understand local conditions!

Snowpack Summary

Up to 30 cm of snow since Sunday has buried a weak layer of surface hoar crystals, sitting over a widespread melt-freeze crust. Despite generally light winds, the new snow is cold, light, and ideal for being redistributed by winds.

Below the surface, the snowpack generally consists of layers of well-bonded snow with various melt-freeze crusts. No significant avalanche concerns at the moment.

At treeline the snowpack depth generally is 100 to 150 cm.

Weather Summary

Monday night

Cloudy with up to 5 cm of snow by the morning. Light to moderate Southwest winds and temperatures around -15 C in the alpine.

Tuesday

Cloudy with snow throughout the day. Amounts generally range from 5 to 15 cm. Light to moderate Southwest winds, transitioning to the Northwest by days end, and temperatures around -10 to -20 C in the alpine.

Wednesday

Sunny, with no precipitation. Temperatures -15 to -25 C and Moderate to strong Northeasterly winds in the alpine.

Thursday

Sunny with periods of cloud. No Precipitation. Temperatures -15 to -25 C and moderate Northeasterly winds in the alpine.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

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.
