Avalanche Summary

A few loose wet avalanches were reported over the weekend during warm sunny periods. With forecast cooler and cloudier weather, loose wet avalanches will be unlikely.

Whumpfing (a collapse of the buried weak layer), was reported by our field team at the Seaton area last Friday, indicating that persistent weak layers still exist in isolated areas.

Snowpack Summary

Areas near Kitimat and the coast may see 5 to 10 cm of new snow accumulations by the end of Wednesday. Elsewhere, a thick melt-freeze crust sits on the surface in most areas, except for high north-facing alpine slopes where some soft dry snow may still exist.

At lower elevations, the surface crust may soften with warming during the day, or the snowpack may be isothermal.

A weak layer of surface hoar is developing on the surface in shady areas at treeline and above.

A layer of weak, faceted crystals overlying a crust, remains a lingering concern for human triggering at upper elevations. In the east of the region, it is buried 30 to 60 cm, and in the west 50 to 100 cm.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
