Schweitzer ski patrol is encouraging and offering weekly free "Transceiver Sundays" (clock tower at 10:00 a.m.) to all interested public with two permanent practice areas and one more difficult challenge that is on a less regular basis. All they ask is that the public covers up their tracks and if practicing digging techniques, please replace your divot. This is a great way to keep on your A game for those venturing out of bounds.
We are currently recieving lots of rain on snow at the upper elevation. This will cause the snowpack to become heavier and weaker. This scenario will greatly increase the likelihood of wet slab activity as deeply buried weak layers in the snowpack become reactive under these conditions.
Because it is currently pouring rain in the Kootenai Region it is unlikely that many folks are going to be out in the mountains. If you do decide to go out realize that this rapid change in temperatures and additional water weight will create very unstable conditions that may result in large avalanches. Travel in avalanche terrain is not recommended today!
The upper elevations recently had 4-8" of loose snow overlying a firm rain crust. As this loose snow becomes warm and saturated we will begin to see many small wet slides. These slides may also be enough to trigger deeper weaknesses in the snowpack and stepdown creating the wet slab problem mentioned above.
Again, today is one of those days where it is best to avoid avalanche terrain or the mountains altogether.
Big thanks to Marlene Kelsch and Libby Middle High School for hosting last nights "Know Before You Go" avalanche awareness presentation. And another big thanks to those that came out to listen.
Today (Thursday February 16th) I will not be going out due to road conditions. I will be out on Friday and posting my advisory by 8PM February 17th.
