Over the weekend, alpine and treeline features were observed running naturally to size 3.5 in the mountains northwest of Terrace. A few of these avalanches were thought to have failed on buried surface hoar. Several avalanches involving the full depth of snowpack to size 3.5 were also reported in the Ningunsaw and Bell 2 areas. One was reported being remotely triggered by a skier from a distance of 150m away. Moving forward, natural avalanche activity is expected to taper-off with forecast benign weather; however, large human-triggered persistent and deep persistent avalanches remain a concern.

Last weekend, between 60-110 cm of new snow fell with the greatest amounts accumulating in coastal areas. Strong to extreme southwesterly winds accompanied the storm and much deeper deposits can be found in higher elevation lee terrain. At lower elevations, precipitation fell as rain and a surface (or near-surface) crust may now be found below about 1000m. Below the recent storm snow you'll likely find a couple of buried surface hoar layers from January 18th and January 23rd. These surface hoar layers continue to produce easy to hard sudden planar shears in snowpack tests, and should be approached with caution, especially in sheltered tree line terrain. The snowpack below this is generally strong and well settled. The exceptions are areas around Bear Pass and Ningunsaw where basal facets remain an ongoing concern.
