With the incoming precipation and warming temperatures, watch for loose wet slides on the existing surface ice crust. The snow just started this morning so watch for how the initial bond is and how heavy the days snow comes in.
Yesterday I travelled into the Purcells area with Ben and Nate off of the Kootenai to monitor the deeper instabilities that the Kootenai have been tracking through the winter. The weak layers deep at the ground are dissipating due to the heavy rains and warm spring temperatures. We observed the remnants of multiple slides that likely released during Saturdays rain event. There was 5" of fresh snow on top of a 4" thick rain crust. Weaknesses within the snowpack are unlikely to be triggered by snowmobilers or skiers. The Selkirks and Cabinets missed out on this snow event with receiving only a dusting that sits on the same raincrust, however this could change with the upcoming weather today where we could see up to 6 inches by tonight. Watch for wet snow and warming temps with the new snow on crust. Expect to see pinwheeling and some loose wet slides with the changes if we get snow with daytime highs in the upper 30's.

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.
