South Coast

Snowpack depths at treeline range from 130-170 cm in the South of the region, and from 80- 130 cm in the North of the region. Light amounts of new snow overlie a variety of old surfaces which may include surface hoar in sheltered terrain, wind-pressed snow in exposed areas, or a melt-freeze crust on previously sun-exposed slopes.In the north of the region, recent storm snow is sitting on a weak layer of buried surface hoar which formed in early December. Facets from December's cold snap also seem fairly widespread in this part of the region. In some areas, these facets may co-exist with a crust in the mid pack. In shallow snowpack areas, the facets may exist at ground level. These persistent weaknesses may likely wake-up with new snow forecast for the rest of the week.

Fair - Timing, track, or intensity of incoming weather system is uncertain

2 size 2 slab avalanches (human triggered and natural) were observed in Marriott Basin in the Duffey Lake area over the last few days. No injuries were reported. The avalanches occurred around 2100m on south-facing terrain. Both were thought to have ran on a crust/facet interface. Check out our Incident Report Database for more details. No other recent avalanches have been reported.
