Weather Forecast
A ridge of high pressure will keep the region dry and sunny for Wednesday, Thursday and Friday. Winds will be light and variable throughout. Freezing levels will likely hover between 500 and 1000 m, although there is a possibility for an above freezing level layer to encroach on this region for Thursday and Friday.
Avalanche Summary
No avalanches have been reported recently from this region.
Snowpack Summary
The upper snowpack comprises a series of storm snow layers, which have generally bonded well to each other and are now gaining strength. Rain fell recently to approximately 1800 m, and has left behind a crust, now buried by a skiff of snow. In the alpine, above the elevation where rain fell, fresh new wind slabs have developed in response to strong southwesterly winds. These were initially from the southwest, but winds have now switched round to the northwest, so expect some reverse loading near ridge crests. Concern for lower snowpack layers remains only in low snowpack areas, such as the east side of the Duffy or in the Chilcotins. Surface hoar and/or facets associated with a crust from mid-December and/or sugary facets at the base of the snowpack could be a concern in sheltered treeline areas that are unusually shallow or on slopes where you can see rocks poking up out of the snow.
