Give the wind slab problem some more time to settle out before committing to larger features. Cold/dry conditions will slowly break down wind slab.
Wind slab can be found on all aspects. Most west facing terrain is scoured but wind slab could still be found on cross loaded features.
Wednesday night: Light to moderate North winds with a Low of -22 at 1600m. No new snow is expected.
Thursday: No new snow expected. Moderate North wind in the morning becoming light North in the afternoon. High of -18 at 1600m.
Friday: light to moderate Northeast winds with no new snow expected. High of -21 at 1600m.
Saturday: moderate winds from the Northeast with no new snow expected. High of -23 at 1600m.
We suspect some natural wind slab avalanches would have taken place on Tuesday.
a few size 2 natural wind slabs were observed in the alpine in the South part of the forecast region on Monday.
Observations are limited. If you are out in the backcountry please consider filling out a Mountain Information Network report.
Westerly aspects are generally scoured but wind slab could exist on some cross loaded features. New wind slab has likely formed on North and East aspects.
The December 15 surface hoar layer is 10 to 20cm below the surface in sheltered treeline and below treeline features. It is likely not a problem yet.
.
Snowpack depth at treeline typically ranges from 100-200 cm, with higher values in the western part of the region and tapering to the east. In the far southwest of the region, the height of snow is closer to 300 cm.
