THIS AVALANCHE ADVISORY EXPIRED ON April 8, 2017 @ 7:34 am
Avalanche Advisory published on April 7, 2017 @ 7:34 am
Issued by Jeff Thompson - Idaho Panhandle Avalanche Center

St. Regis Basin/Silver Valley

bottom line

The supportive crust near the surface of the snowpack is breaking down quickly with the warm temperatures and rain. The rain percolating through the snowpack will break down some of the strength. Expect to see unsupportable snow in the backcountry. Human triggered avalanches are still unlikely but possible. Natural avalanches are a possibility especially on steep slopes with a smooth bed surface. Safe travels!

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.
