Northwest Coastal.
Continue to assess the wind slab hazard before committing to steep features. Wind slabs are becoming less reactive but they are still possible, especially near ridge crests.
Sunday night: moderate to strong outflow winds will continue at all elevations with a low of -25 at 900m. No new snow is expected.
Monday: up to 10cm is expected in the morning with light t west winds at treeline. A high of -17 at 900m.
Tuesday: Sunny with a high of -14 at 900m. winds will be light from the north at treeline.
Wednesday: light snow throughout the day with moderate southwest winds at treeline. High of -14 at 900m.
Loose dry avalanches up to size 2 in steep terrain continue to be reported in the region. Two wind slabs up to size 2 were observed at 1200m on southwest aspects on Saturday.
Moderate to strong outflow winds at all elevations have scoured east aspects and formed wind slab on west aspects.
Another surface hoar layer was buried recently , it is not a problem yet.
The December 18th surface hoar/facet layer is down 30cm, the surface hoar was observed up to 12mm in both the treeline and below . It is likely only a problem in isolated locations in the treeline where wind slab has formed above it.
The December 7 persistent weak layer is now typically down 100cm and has not produced avalanches in over a week.
Snowpack depths vary greatly across the region, expect to find anywhere from 100-300 cm of snow around treeline.
