Last advisory of the year!! Current snowpack conditions are looking stable overall. With some light snow accumulations this past week, and strong southwest winds yesterday, it will be possible to trigger pockets of windslab at upper elevations. Use caution in steep terrain on north and easterly aspects, steep rolls and chutes. These will be the spots to be wary of this weekend

As the temperatures heats up during the sunny days, expect the avalanche danger to rise. Wet, loose slide potential is a danger that is easy to mitigate: when you start seeing rollerballs or sinking in slushy snow, it's time to head out of avalanche terrain.  And give those cornices a wide berth, they start failing as the temperatures heat up.

New snow from last weekends storm will be your main concern right now. In very steep terrain (over 35°) it will be possible to trigger avalanches in the upper 6-10" of the snowpack. On due north aspects these slides will come in the form of loose-dry slough or thin soft slabs. On solar aspects expect to trigger wet slides in steep terrain as the afternoon sun warms the surface.

I'm sorry we had to close up shop early this year but spring is tomorrow and I'll leave you with some Spring Touring Tips that everyone can use.  I'll also update you on our snowpack conditions.  Even though we had a short winter, by my standards, things are looking pretty good in the high country so there is plenty of snow to continue riding and sliding.  Melissa and Ben will submit advisories through March.

Kootenai avalanche advisories will be posted on Friday mornings for the rest of March. With the closing of Montana schools I will be unable to venture into the mountains on Mondays. I will however provide the best intel I can regarding snow conditions without a hazard rating attached. This info will be based on weather and my tracking of the winters' snowpack. My apologies for the interuption in the Tuesday morning advisories!

Big change is coming on Friday. A strong cold front will bring an additional foot of snow and strong northeasterly winds to the mountains area wide. Anticipate the buildup of wind slabs and drifts at all elevations this weekend. Use caution in all steep and open terrain that has been exposed to the wind. Shooting cracks, drifting snow and increases in the surface density will be your obvious clues to pay attention to this weekend.

Yesterday in the Cabinets I found good sliding conditions but a little crusty on the southerly slopes.  Not much stability concerns on these slopes due to multiple crusts in the upper pack.  However, on Lunch Peak I found two very distinct layers of buried surface hoar on a north aspect.  Be careful on steep, convex terrain on NE - N - NW aspects.  The wind has cranked up too so watch for windslabs on these aspects too.

A strong winter storm is producing heavy snow and wind across the forecast area. 2 ft of snow is already on the ground (above 4500').  The rain/snow line is currently hovering around 3800-4000'. Dangerous avalanche conditions exist in the backcountry. Strong SW winds combined with new snow will create an unstable snowpack on all aspects above treeline. Travel in the backcountry is not recommended

Snowpack conditions are becoming highly variable with regard to aspect and elevation. Your biggest concern is colder snow on north aspects that hold a weak layer below the current surface crust. Use caution on steep, complex terrain on northerly aspects

Complicated weather makes for complicated snowpack layers. Simplified, there are lots of windslabs and crossloading out there, with more forming over the weekend.  We have a multitude of buried persistent weak layers, the most reactive being a buried surface hoar layer from earlier this week. Avoid both these problems by riding conservative terrain.

There is a alot of variance in the snowpack and some tricky weak layers across the area right now. Storm slabs resting on buried surface hoar will be the primary concern and may become more sensitve on Friday if the temperatures rise at mid-elevations. Stick to lower angle terrain and take the time to assess the snowpack before committing to steep slopes.

Happy New Year! 2020 is going to be welcomed by a strong winter storm! A strong winter storm showed up in the panhandle last night. This storm looks like it will linger around until the weekend. Expect to see 30'' of snow above 5000' by the weekend. Even though the avalanche danger is pretty tame right now, I expect it will increase with the new snow.

Out with the old and in with the new...doesn’t exactly translate to snowpack and avalanche risk. Still of concern are our persistent weak layers. They are getting more stable, but could be woken up again with new loading. Wednesday will bring us some different problems to consider for the first day of 2020; storm slabs and windslabs. Expect the avalanche danger to rise as the next storm cycle hits.

Our current snowpack conditions are very stable but that will begin to change by Tuesday night. A winter storm will bring 1-2 feet of fresh snow and strong winds out of the southwest which will cause avalanche hazards to rise by Wednesday. Be on the watch for fresh storm slabs and wind slabs at tree-line and above throughout the week!

Our main concern is still buried persistent weak layers that have the potential to slide to ground.  Areas where the ground surface is smooth, such as beargrass slopes, have a higher probablity of sliding if an avalanche is triggered. We expect to continue to see reactive persistent weak layers for a while with the weather pattern that we are experiencing. Bottom line is we have a thin and weak snowpack.

The snowpack is still recovering from 8'' of water in a 48 hour period last weekend. The large amount of water increased the avalanche danger significantly but since then we're trending towards a more stable snowpack. Look for cooling temperatures heading into the weekend.

The snowpack has bonded well after last weeks storm. The biggest threat right now will be small windslabs in steep terrain at elevations above 6,500' on northeasterly terrain near ridgelines. Continue to use caution in high terrain where the snowpack appears to be thin and rocky as these may be locations where deeper weak layers may be senstitive to human triggers.

The storm system that rolled through over the weekend wasn't exactly what we were hoping to get for Christmas. Above 6000' we are still seeing reactive basal facets.  Below 6000', the snow pack is still stabilizing after recieving so much moisture.  Temperatures are starting to be more winterlike again, so that should help lock up the lower elevation snowpack.

Put away the rain gear.  The temperatures have dropped, winds are calm, and the snowpack has settled.  A new rain crust has formed near the surface and about 6 inches of new snow sits on top of that with a decent bond to the crust.  Use caution in steeper terrain at elevations above 6,000 feet.

Avoid steep terrain above 6,000' on north and east aspects. It will still be possible to trigger the recent storm snow in these locations and triggering small windslabs will be likely on high, steep terrain. These winds slabs and storm slabs will decrease in sensitivity during the week as temperatures return to seasonal normals and the winds subside.

Heavy, dense snow as well as some rain hit the region last night on top of the lighter snow we recieved yesterday. This creates an upside down pack that will take time to stabilize, especially in shallower areas where there are buried persistent weak layers.  The winds have been steady so expect to find windloading as well.

Winter just got kicked into full gear! A strong winter storm arrived yesterday and continues to drop a big snow and rain on the Selkirk and Cabinet mountains. A large heavy snowload will put stress on the underlying weak layers in the snowpack. The snow/rain line looks to be at 4500'

Heavy and dense snowfall is stacking up on a slick and reactive snow surface. Expect avalanche danger to remain HIGH throughout the weeked as more snow and strong southerly winds pound the Kootenai region. Avoid riding on or below steep terrain above 5,000' this weekend

Continue to be wary of steep and open terrain at upper elevations, it is possible to trigger a slide in the upper 12" of the snowpack in areas affected by the wind. The deeper weak layers will be very resistant to triggers but they are still there and will result in a destructive slide if you find that weak spot. Moving into the weekend expect the avalanche danger to rise as another storm brings heavy snow to the area.

Shallow snowpack with hollow facets close to the ground and a few surface hoar layers in the upper half of the pack.  Upper elevations with steep and open terrain is where one has the greatest chance to trigger an avalanche currently.  However be aware of how the storms stack up later in the week and what the upper pack becomes ontop of existing persistent weak layers.

New precipitation from the weekend has settled, but don't become complacent out there. Most locations have depth hoar as well as a buried surface hoar layer that are still being reactive.  If you feel the snow settling or collapsing as you travel, that's a red flag to stick to the terrain under 30 degrees. We don't have much snow on top of these layers right now, but as the week brings more snow expect the danger to rise.

A strong winter storm has been blanketing the forecast area with new snow and wind over the past 2 days. The snowpack is quickly becoming more complex and the avalanche danged is increasing at upper elevations. The new snow buried a surface hoar layer, which will increase the likelihood of avalanches in the backcountry.

New snow and winds overnight fell onto a shallow snowpack that hasn't had time to adjust.  Hiding just underneath this new snow is a buried surface hoar layer that was proving to be reactive yesterday, especially in windblown areas.  As we don't have enough snow to ski and ride yet in the lower elevations, today's forecast is for only above treeline.
