The Selkirks and Cabinet mountains continue to be in an active weather pattern. Another period of unsettled weather will begin today and carry through the weekend. The avalanche danger will increase as the new snow arrives. Always assume the new snow will increase the avalanche danger. New snow usually takes a couple days after a big snow, to adjust to the old snow . I'd expect the avalanche danger to trend up over the next 48 hours.

Expect to trigger windslabs on steep and open terrain on all aspects. Wind slabs will be most dangerous in cross-loaded gullies, chutes and leeward terrain below ridgelines where the surface snow has been deposited into a deep and cohesive slab. This problem can be avoided by staying in the sheltered timber locations and avoiding the steep and open areas through the week. This will also give the new storm snow time to settle out and bond with the existing snowpack.

Warm temperatures and moisture will continue to add snow to the mountains above 5,000' and rain below. Expect to see small "loose-wet" slides at lower elevations. At upper elevation dense storm slab avalanches are possible in open and steep terrain (over 35°). Primary areas of concern are southerly exposures in the Cabinet Wilderness where the new snow is falling on a sun-crust layer that developed last weekend.

Another winter storm is on the door steps! Strong winds and snow will start today around 10 AM. This winter storm could produce 35'' of snow by the weekend. The snow from the last 7 days has settled down a bit and seems to be increasing strength. I expect all of the new snow, in the coming days, to ruin the snowpacks healing trend.  Expect to see the avalanche danger start to rise with the arrival of this storm.

Be on the lookout for the potential to trigger wind slabs in steep terrain below ridgelines and cornices. There is extensive evidence of wind loading in the mountains and these wind slabs are becoming less reactive with time. Recent Storm snow is quickly settling and gaining strength but still has potential to fail at upper elevations.

The snowpack is currently recovering from the recent storms. The Cabinet and Selkirk mountains received well over 3' of snow, which added a huge load and increased the avalanche danger. Currently we're seeing the snowpack heal and gain strength back from the big weight added last week. Even though the snowpack is healing, there are still plenty of instabilities to be aware of. Cold temperatures and small snow storms will dominate the weather pattern for the rest of the week.

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.

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.

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.

Thirteen inches of new storm snow in the Cabinets and a deep weak layer in the middle of the snowpack. Avoiding steep slopes (over 30°) through the weekend will be your best bet to avoid triggering an avalanche. Above 5,000' is where you will find avalanche concerns. Sticking to lower angled terrain and ridgelines is where you will find the safest riding.

The daytime temperatures have been above freezing for a week or so, which creates melting and ultimately a more avalanche prone snowpack. Fortunately, the cooler nights have been refreezing the surface of the snowpack which has been saving us. The best plan now is to get out early when the surface is still firm and frozen. Stay away from sun soked slopes with signs of melting.

Be especially aware of slopes that have long exposere to the sun.  Practice safe travel techniques, stay away from terrain traps and look for signs of a weakening snow.

You will see small avalanches in steep terrain that is being cooked in the sun on Friday. By the weekend incoming weather will provide cloud cover and reduce the danger of loose wet slides in steep and solar affected slopes. Stay safe by moving to lower angle terrain  or shaded aspects when the sun comes out.

The mountain weather forecast is dipping barely below freezing at nights above 5000' for the next couple of days. Day time temperatures are predicted to be downright blazing, which will cause rapid change on the snowpack.  Expect the wet slide potential to increase as the day warms up.  If you are seeing natural pinwheels and rollerballs, head to the cooler side. If there isn't a cooler side, head to mellower slopes.

Spring conditions are here in full force! We've had many reports of wet avalanche activity across the region.  Expect to see the avalanche danger increase throughout the day. As air temperatures rise so does the avalanche danger. Be particularly careful on solar aspects (E-S-W). I anticipate seeing a increase in avalanche activity over the the next 48-72 hours.  Enjoy the sun but keep it safe!

The avalanche danger will fluctuate from LOW in the mornings to CONSIDERABLE in the afternoon as the sun warms the slopes and reduces the strength of the snowpack. You will see small avalanches in steep terrain that is being cooked in the sun. Stay safe by moving to lower angle terrain when the sun comes out.

With cool nights and daytime temps hovering at the freezing level and sunny days, solar aspects will be most affected towards the middle of the day warming the upper snowpack especially on steeper slopes where the sun angle is the greatest.

The weather looks like we've solidly hit spring weather for the extended forecast!  The sun beating down on the snow will make the instability increase  through the daytime due to the potential for wet avalanches.  Beat this by playing the game of aspects.  Hit your SE-S-W aspects in the morning before they heat up and head to the North as the day progresses.  And don't forget your sunscreen!

The primary weakness right now is 11" below the surface. It will likely cause problems in isolated locations or on slopes that are exposed to the heat of the sun. Asses the stability and consequence of steep slopes individually before diving in headfirst. Now that is is March pay attention to the effects of the sun and move off of steep slopes that are exposed to the sun as the days heat up!

A winter storm will deliver up to 14" of heavy snow by Wednesday morning.  Expect the avalanche danger to increase as the storm accumulates, hitting CONSIDERABLE by tomorrow. The main concern will be wind slabs on the N - E aspects.  Watch for storm slabs as well; this snow will be falling on crust on the W - E aspects from all the sun we recieved over the weekend and patches of surface hoar in sheltered areas on the N.

People get ready, there's a change a comin.  Warmer temperatures, wind, and new snow will fall on a firm snow surface on many aspects and also a patchy layer of surface hoar.  The storm just began about 4AM so conditions have not reached a problem level yet, but expect the hazard to rise to Considerable or High by later today and last into tomorrow.

Tuesday will bring more snow and southwest winds. Expect windslabs to continue being the main concern on North and East aspects in steep alpine terrain. The new snow may form thin storm slabs as well that will take a couple of days to bond. Use caution in steep terrain and loading zones where even small slabs may take you for a ride.

The Wednesday/Thursday storm came in warm and cooled down, bonding well to the old snow and leaving us with a new, clean, fluffy riding and sliding surface.  Winds are back to our prevailing direction, so heads up for wind slabs in the NW-E aspects.

The recent cold temperatures have kept the snowpack from showing any signs of spring. Don't worry...it's coming! As the sun gets higher in the sky and air temperatures start to rise, be ready for a rapid warm up and melt. For now...enjoy the good sliding surface and keep an eye out for wind slabs.

With a modest dose of fresh snow and strong south west winds we will continue to list WINDSLAB as the main concern. Expect to find dense slabs of snow near ridgelines and steep rolls. Watch for shooting cracks in the surface of the snowpack and be very wary of steep, unsupported terrain on north and easterly aspects when dropping off of ridglelines this weekend.

The current challenge is to find good snow that hasn't been hammered by the winds over the last week.  To avoid the wind slab problem on our SW - N aspects, search out cold powder that is lingering in the timbered areas that have been protected from the winds.

We are currently enjoying good general snowpack stability with windslab problems on specific terrain features. Strong east winds have loaded west aspects just below ridgelines and cross-loaded chutes on north and south aspects. For the best and safest riding conditions look for soft snow in timbered areas where the surface snow hasn't been hammered by the wind!

Continuing cool weather and no recent snowfall has helped maintain and stabilize the snowpack.  The snowpack has settled and consolidated losing over a foot of overall snowdepth creating more stable snowpack.  Cool air temperatures have been sucking the moisture out of the upper pack and breaking down some of the weaker windslabs creating recycled powder.

Your biggest concern today and this weekend will be windslabs that may be touchy in steeper terrain.  They exist on all aspects and many are very firm and solid.  Be wary of breakable windslabs on steep, convex terrain.  The great sliding conditions continue with cold temperatures and light additions of new snow.  Overall, the upper pack (3-4 feet) is gaining density with depth and is structurally solid.  Get out before the next deep freeze arrives.

The old proverb of "In like a lion" seems to be holding true for us.  The cold weather is still sticking around, which means lots of light, fluffy snow avaliable for wind transport. Wind slab growth will continue through the weekend with cold, windy weather.  Stick around until the end of March and we'll see then if the rest of the proverb holds true as well.

General snowpack stability is improving area wide on the Kootenai and the primary avalanche concern will continue to be windslabs this weekend. With southwest flow today followed by another incoming cold front expect to find new wind slabs developing on any aspect at upper elevations. The likely trigger spots will be below ridgelines, steep and cross-loaded chutes or steep convex rolls.

This cold weather keeps lingering around, as do the winds from directions that aren't our prevailing direction.  Over the past day we've seen winds from the E-SE and N, and they are supposed to be from the E - NE today and tomorrow. Heads up for wind slabs in the steep terrain below ridges, convex rollovers, and crossloading.  Avoid these areas by entering the slopes low in the sheltered timber.

Strong north winds are going to dominate the weather pattern, for the next couple of days. We'll continue to see cold temperatures and small amounts of snow over the next 48 hours. The snowpack is pretty strong and supportable in most places. The cold temps have kept the surface snow loose and light providing good sliding conditions in protected or sheltered places.

Strong northeasterly winds have created windslabs in atypical locations and they will continue to build through the day Tuesday. Use caution in steep terrain below ridgelines, steep and convex rolls and cross-loaded chutes. Better snow, less wind and safer conditions can be found in the sheltered protection of the timber right now.

The snow from last week has continued to strengthen over the past several days without any new loading on top of it.  We still have reactive wind slabs on multiple aspects as we've had varied wind directions this week.   And our buried persistent weak layers are still down there lurking in the pack.  Assess your riding area before committing to steep, complicated terrain.

Generally stable snowpack conditions exist right now but there are hazards at isolated locations in steep terrain at treeline and above. Take the time to assess each slope individually before committing to any steep chute or exposed ribs where a small pocket of slab may wreck your day.

New snow has had time to bond with minimal new snow this week.  Light accumulations expected the next few days.  Watch for wind loading on Saturday.  Variability is key to remember as persistent slabs still exist in pockets with high consequence.

Cold temperatures have stiffen and settled the snow near the surface. Most areas I traveled to yesterday. had very supportable snow with 3-5'' of light snow blowing around on the surface.  I observed a lot of erratic wind loading from many different directions so becareful around terrain your familiar with...it may have taken on a different character over the past week or so

The snow from last week has continued to strengthen as it settles but with moderate winds from multiple directions over the weekend, expect to find wind slabs on all aspects below the ridgelines. Also look for cross loading on steep, open terrain that has been exposed to the winds.
