THIS AVALANCHE ADVISORY EXPIRED ON January 16, 2019 @ 6:11 am
Avalanche Advisory published on January 15, 2019 @ 6:11 am
Issued by Jeff Thompson - Idaho Panhandle Avalanche Center

Selkirks/Cabinets

bottom line

A couple days of sunshine and warm temperatures, have helped settle and consolidate the snowpack. A rain crust on the surface doesn't provide the best traveling surface, but there's something to be said for good stability and visibility! Be especially heads after the next significant snow storm. Even though the sun is helping heal the pack right now, it will leave a firm slide surface in it's wake.

Persistent slabs are still the big problem. I don't completely trust this snowpack because of it. Yesterday we found a buried surface hoar layer midpack that is there but still lying dormant. One of the ways a Persistent weak layer can come alive is during a rapid warm up, so keep that in the back of your brain. It's worth looking at that layer before exposing yourself to avalanche prone slopes.  Watch out on south slopes baking in the sun all day and areas of thin snowpack (near rocks, cliffs, convexities)

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.
