Avalanche Summary
Large natural avalanches up to size 3.0 have been reported from the Bear Pass and the coastal mountains near Terrace. There are no reports of human triggered avalanches.
Snowpack Summary
Very strong SW-NW winds may wreak havoc on the snowpack creating scoured areas and soft or hard wind slabs in exposed lee terrain and cross-loaded gullies or terrain features. Coastal areas are reporting a very deep and strong snowpack which is at or near record levels for this time of year. A buried surface hoar layer may be found down 100-150cm near Terrace, but there is no recent information on the presence and sensitivity of this layer.
