THIS AVALANCHE ADVISORY EXPIRED ON April 6, 2017 @ 8:20 am
Avalanche Advisory published on April 5, 2017 @ 8:20 am
Issued by Jeff Thompson - Idaho Panhandle Avalanche Center

Selkirks/Cabinets
St. Regis Basin/Silver Valley

bottom line

I was sure nice to see the sunshine yesterday! I dug a snowpit yesterday north of Schweitzer mountain in the Selkirks (6200ft). There is 30-40cm crust near the surface that is very supportive. I don't see the avalanche danger increasing until that thick crust gets broken down. Rain and warm temperatures might try to break down the crust layer but my feeling is that overnight temperatures will be cold enough to keep it intact for the extent of this forecast.

How to read the advisory


  • Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

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.
