Selkirks/Cabinets

bottom line

Strong north winds are going to dominate the weather pattern, for the next couple of days. We'll continue to see cold temperatures and small amounts of snow over the next 48 hours. The snowpack is pretty strong and supportable in most places. The cold temps have kept the surface snow loose and light providing good sliding conditions in protected or sheltered places.

Be ready to see reverse loading in many areas. The north winds have transported a lot of snow into starting zones that don't normally have this much loading. Be especially mindful when traveling on ridges and near areas of wind effect.

Usually a buried persistent layer comes to life when big change happens quickly in the snowpack. Recently the snowpack has been experiencing cold temperatures. When those cold temps make their way into the snowpack, it can make persistent layers more reactive. Keep an eye out for signs of deep instability.  Please report obs. to IPAC

Disclaimer

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.  For a recorded version of the Avalanche Advisory call (208)765-7323.
