Regions

Glacier.

Evaluate snow and terrain carefully before committing to your line. Human triggered avalanches are still possible.

Confidence

Moderate

Avalanche Summary

Natural avalanche activity has eased.

Neighboring operations are reporting rider & remote triggered avalanches on the Jan 30th layer.

A sz 2 wind slab was triggered by a skier part way down Forever Young, resulting in injuries.

A sz 1.5 wind slab on the Ravens was observed while flying to the above accident.

Snowpack Summary

Variable winds had caused widespread wind effect, which is starting to facet out in places however, can still be found in specific terrain features in the alpine & tree-line elevations.

Last week, 40cm of storm snow buried a weak layer of surface hoar, facets and/or suncrust (Jan 30th layer).

The Jan 7th layer is down 50-80cm, comprised of surface hoar and/or a thin crust on steep S aspects.

The basal snowpack is dense and strong.

Weather Summary

An area of upper level instability will begin to track down the province bringing scattered flurries to the BC interior.

Tonight Clear with cloudy periods. Alpine low -16°C. Ridge wind SW 25km/hr.

Sat Cloudy with flurries. Alp high -15°C. Ridge wind: W 10-20-35km/hr.

Sun Cloud & sun with isolated flurries. Alp high -18°C. NW wind 20-30km/hr.

Mon Sunny. Alpine high -18°C. Light NW winds.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.

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.
