Watch for wind loaded features as you move through terrain. Rapid wind slab development is expected where loose snow is available for transport as strong to extreme westerly winds continue.
On south facing terrain these wind slabs could sit over a thin sun crust. On other aspects new wind slabs are likely to form on a layer of facets or surface hoar in sheltered terrain. Triggering a wind slab over surface hoar, facets or a crust could result in a larger avalanche.
No new avalanches have been observed in the past few days.
If you are heading into the backcountry please consider filling out a Mountain Information Network report.
Strong westerly winds have redistrubted recent snow into wind slabs at higher elevations. On south facing slopes wind slab could have formed over a sun crust. A layer of surface hoar down around 30cm can be found in sheltered terrain on all aspects up to 2000m, This layer could be a concern where wind slabs form above.
A weak layer consisting of facets and a crust formed in November is now buried around 60cm deep.
In general, the snowpack is quite weak and faceted with average snowpack depths of around 150cm at treeline.
