In sintesi

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

    Use caution in wind affected terrain and be aware that any wind slab avalanches could step down to our persistent weak layer

    20-40cms of recent snow is settling over a buried weak layer. This weak layer is consists of surface hoar, facets and suncrust (on south and west facing slopes). It will be most reactive where there is a settled cohesive slab.

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.
