We haven't received any reports of avalanches from the region, but expect some natural activity to have occurred.

Wind slabs and storm slabs continue to build above a weak facet layer which formed during the brutal cold of mid-January and was buried around January 20th. Avalanches have begun to release on this layer in the Coastal regions, and it's probably just a matter of time before a critical load builds up above it in further inland. Tests on this layer in the Seaton Basin have produced moderate, sudden planar ("pops") shears, indicating that an avalanche releasing on this layer could propagate widely. In the Howsons, the facet layer was buried with very little wind effect in the alpine, at the same time that the northeast outflow winds were howling in Terrace. Rising temperatures and snowfall during the weekend will increase the likelihood of storm slab avalanches, which could be very large. In shallow snowpack areas, a weak, "rotten" snowpack has been observed.
