Avalanche Summary
No recent avalanches have been reported in this region, however, this may change if wind speeds increase and create touchy soft slabs.
Snowpack Summary
Much of the region received 10-15 cm of new snow with locally higher amounts (30-40 cm) around Fernie. So far this new snow has fallen with no wind and made for great skiing. If winds increase, expect touchy soft slabs to form in wind affected terrain. This new snow is sitting on top of a mixture of surface hoar and weak surface facets. The mid pack is reported to be well settled. There is sufficient snow on the ground for avalanches at treeline and alpine elevations, and possibly in some below treeline locations. Reports suggest typical treeline snow depths are around 110-150 cm, but a report from the east side of region indicated a much lower snow depth of around 90 cm. Limited reports suggest the crust from the middle of November is down 50-80 cm and the crust from early November is down 80-110 cm.

Fresh soft slabs will be most reactive in wind affected areas.
Use caution as you transition into wind affected terrain.Use small slopes to test the bond of the new snow.Avoid terrain traps where small avalanches may have severe consequences.
