The deep mid-November crust appears to be waking up and several avalanches have recently released down 200 cm in the snowpack.  Conservative terrain selection is critical while the alpine snowpack is warmed for the first time this winter.
We had one report of a deep persistent slab avalanche size 3.5 at Mt Harmer that released during the storm. Terrain with similar exposure to the wind and a shallow weak snowpack may behave in the same manner.
There have been two natural deep persistent slab releases in the past two days in the Lizard range. Both of these avalanches were on northeast aspects in the alpine, and released to size 3.0 or larger.

The lack of an overnight refreeze will make the impact of Saturday's 2200m freezing levels even stronger. Warming aside, new snow, wind, and rain are set to provide ample natural triggers for deep persistent slabs.
Be careful not to overestimate the stabilizing effect of cooling temperatures on Sunday. Rain has saturated the snowpack with warmth and deep persistent slabs still have the potential to release naturally or with a sufficient trigger on Sunday.

The cold has started to break down the midpack at all elevations which helps limit the size of avalanches. However, significant avalanches are still a possibility due to the entire snowpack being involved. Treat large terrain features with respect.
Stiff windslabs are the main concern at this time.&nbsp; These slabs may be triggerred from a thin snowpack area so pay attention to snow distribution as you travel.
Stiff wind slabs still exist throughout the forecast area and these sit on the weak basal facets. Though difficult to trigger, this weakness could produce large avalanches. Thin snowpack areas are a potential trigger point.
The basal weakness remains, and incoming snow and wind may lead to a re-awakening of this problem. Large terrain features should be avoided.
Its unlikely that this new snow will re-awaken the basal weak layers but keep it in your mind that it will be tougher for you to see the thin weak areas where it may be triggerred by you!
The new load is a concern with this layer. Forecasters are unsure of how the basal layers will handle the rapid load. LOTS of whumphing and cracking on those lower layers today. Assess snowpack depth by probing to get a feel for what's beneath you.
We havent seen any action on the Basal facets in sometime now but remember that this weakness persists down low in the snowpack.
Forecasters are waiting to see if this layer wakes up with the new load. So far there has been no activity on it, but if that changes look out. Large avalanches are possible with this layer.
Thin rocky areas are still the likely trigger point. There has been no activity seen on this layer, but the potential is still there. Stepping down may become a concern as the wind slab avalanches grow in size.
"> Likely trigger points are thin areas where it is more difficult to recognize the hazard due to the presence of new snow. While we are seeing little action involving this weakness it remains a concern due .

Avalanches releasing on the deeply buried weak layer from early February are still a concern. Strong solar radiation, cornice falls, new loading, or storm slab avalanches in motion are all possible triggers.
Highly destructive avalanches are expected to continue on this weak layer. The variable nature of the problem makes it difficult to predict when and where avalanches are going to occur. Sun and warm temperatures may 'wake-up' this layer.

An avalanche that is initiated in the upper snowpack could step down to the basal weak layers.
Slab failures are sometimes stepping down to the November rain crust.
Facets overlying the Nov 6th crust are still producing whumpfs and settlements indicating that this layer is still possible for skiers to trigger.
The Nov crust is beginning to facet out in some areas but still use caution and evaluate this deep weakness.
Thin spots, heavily wind loaded features and steep rocky terrain are areas where the Nov6th will be a bigger problem. Dig down to assess the crust and its reactivity if in question.
This layer has been the main sliding layer over the past week.&nbsp; Expect any new slides to step down to this layer.
A layer of facets overlying the 1106CR has been responsible for many avalanche over the past week.&nbsp; Did down and evalulate this interface as you travel.
Recent warming has created a more cohesive slab over the November rain crust. Stability tests today indicate that human-triggering is likely.
Slabs are sitting on a weak basal combination of facets overtop of the November rain crust. Wide propagations and more sensitive triggering are now possible due to the recent increase in slab density.
Rain and warm temps have the potential to wake up this basal layer.
At higher elevations, there's still a significant amount of snow resting on this layer waiting for a trigger. Avoid avalanche terrain until the weather cools and stabilizes the snowpack.
A layer of facets over this weakness will be most easily triggerred from a thinner snowpack area.
The basal weakness will plague the snowpack for some time. This problem is likely more triggerable in the Alpine at the moment, due to recent re-freezing of a rain-soaked snowpack at lower elevations.
Be cautions around thin snow pack areas
The weak basal layers are the principal concern in the snowpack. Dense slabs now overlie these basal layers. While these dense slabs provide some bridging strength, if a slab is triggered the consequences could be significant.
We are relying on the dense midpack to shield us from a failure of the Nov 6th. In shallow areas, the likelihood of triggering the deep layer rises dramatically. Probe to confirm snow depths as you approach bigger terrain.
The likelihood of triggering a deep persistent slab has decreased but the consequences remain very high. Be wary of any slopes that did not release during the storms. Heavy triggers such cornice falls may be able to trigger a deep weak layer.

Although unlikely, these highly destructive avalanches remain possible with heavy impacts (e.g. cornice falls and surface avalanche stepping down) in the right spot (e.g. thin rocky areas). Daytime warming will also increase sensitivity.
This problem commands a lot of respect. Avalanches stepping down can entrain large amounts of snow right now making for large destructive avalanches. Large triggers should be a concern right now.
As the upper layers gain strength through the cooling process, we can expect this layer to settle down and become less active. Having said that, remember that thin spots can be problematic. Large triggers are still a concern.

Thin areas, and paths that have not avalanched during the cycle are more likely to have this problem.
The natural cycle a few days ago seems to have cleaned out many start zones. Thin and/or variable start zones with no previous activity are worth some thought and consideration.
The widespread cycle last week has eliminated this problem from many areas. Alpine slopes that haven't avalanched yet will still have the potential for these avalanches. Use this to help choose terrain
Weak basal layers are prominent throughout the forecast area. While the probability of triggering the basal layers is less likely, the consequences are large.
Keep an eye out for cornices as possible large triggers, especially when the sun comes out and the temps begin to rise.&nbsp; This basal weakness is still on our radar.
As our snowpack slowly grows it becomes easy to forget about the bottom layers. Remember that the bottom is still weak in many places and requires a deep snowpack to safely bridge the bottom layers.
Large triggers have recently impacted this layer in variable depth terrain. Watch for a weak snowpack in alpine areas and anticipate where the thin areas might be. Probing is a valuable tool to figure out snow depth trends.
The ground cover and elevation seem to be a factor here. This layer is much more prominent in high rocky terrain, where the depth hoar is more persistent and slow to change. Assess these transitional zones and watch for trends as you travel.
This is a very low probability problem with large consequences. A weak basal layer resulted in several full depth avalanches during the last sunny period which could be repeated this weekend. Avoid steep sun exposed slopes during the afternoon.

Some recent cornice triggered avalanches show us that big triggers can easily hit the deeper layers and cause a slide. Be to sure to assess overhead terrain from a potential triggering perspective
This problem presents as a layer of depth hoar at the base of the snowpack. To get this going we need either a large trigger or to hit the shallow &quot;sweet spot&quot; while skiing. Steep, shallow areas with a hard slab on top should be treated with caution.

The weak basal layers are still prominent in the forecast area. The probability of triggering this deep weakness is low, but the resulting avalanches could be very large. Large triggers such as cornices could trigger this weakness.
The probability of triggering this basal weakness is low, but if the trigger is large enough such as a cornice, the resulting avalanche will be quite large.
This layer still lingers in shallow areas. As the midpack facets more and more, it will lose its bridging properties making it easier to trigger the deeper layers. Watch for this situation in thin snowpack areas especially.
This may be more of a concern at treeline where windslabs have become softer due to facetting.
It will take a significant trigger, or a shallow spot to initiate the deeper layers right now. Watch snow depths as you travel and stick to the deeper areas. Especially as you enter your line.
In most places the bottom of the snowpack is depth hoar. Thin areas around alpine features should still be treated with caution. Be sure to enter your line in supported terrain with a thick snowpack.
We've officially hit the low probability, high consequence stage with this layer. Steep terrain with exposed rocks and a shallow snow pack are a considered a trouble area. Treat these areas with caution.
With the forecasted mild temps in the alpine, be aware of the strong effect of the sun this time of year should it appear. Large triggers such as cornices will weaken and could trigger this basal weakness.
Steep and shallow snowpack terrain should still be considered suspect. A skier triggered avalanche occurred yesterday on a steep solar aspect in the alpine.
Deeper weaknesses still exist and remain a concern in shallow rocky areas or anywhere the thick near-surface crust is weakening or non-existent, specially north aspects above 2200m.
Shallow snowpack areas that are steep should be treated with respect. These features are the most likely to steep down to basal weak layers and produce a full-depth avalanche. Large triggers such a s cornices are also a concern.

The basal weak layers ares still a concern in steep alpine terrain, especially in shallow snowpack areas. Large triggers, such as cornices, may also be enough to wake up this deep persistent weak layer.
As the snowpack warms up, remember that this layer will be easier to trigger. Cornices, loose wet, wet slabs are all potential triggers at this point.
We have concerns about this problem &quot;waking up&quot; with warm temperatures. A crust that previously isolated deep weaknesses has broken down with warming. Recent whumpfing indicates unstable snow.
It is unlikely to trigger this layer, but in steep convex terrain there is enough potential to keep it on the list. Large triggers are also something to think about. Cornices may be likely trigger.

Weak layers at the base of the snowpack may still be triggerred from variable or thin snowpack areas.
Several days of warming followed by rain up to alpine elevations may result in avalanches releasing down to persistent weak layers. Avalanches releasing or stepping down to deeply buried weak layers may result in large destructive avalanches.
The basal weak layers remain a concern and could &quot;wake up&quot; with the new load of snow forecast for Sunday night. Shallow snowpack areas are particularly concerning in this respect.
Recent very warm temperatures followed by heavy rain, and then the forecast snow and wind, may be too much change for the snowpack to manage. Avalanches releasing on the deeply buried weak layers are expected to be large and destructive.
Recent loading may make the basal weaknesses more sensitive, especially in shallow snowpack features.
The recent new load of snow could be enough to awaken the basal weak layers, particularly in shallow snowpack areas.

Unlikely to trigger, but large triggers such as cornices may wake it up.&nbsp; Other things such as rain may also wake up this basal weakness.
There is a chance this deep layer could wake up with the very rapid loading pattern expected tomorrow.
No activity on this layer in some time, but its still in forecasters minds.
The basal weak layers have been dormant for some time, but the potential remains for a low probability, high consequence event due to the structure of the snowpack. Be mindful of this issue in shallow snowpack regions and when the snowpack warms up.
This layer is becoming increasingly hard to trigger. In steep terrain, a hidden thin/weak spot could potentially trigger a large avalanche.
The basal weak layers have been dormant for some time, but with the snowpack warming up each day thin snowpack areas in steep terrain are still a concern for triggering.

Full depth, human triggered avalanches are likely in specific features. This basal crust/depth hoar problem will last for a while to come.
At this time all steep slopes have the potential to step down to the basal facets and result in large avalanches. The snow depth is quite variable across the forecast region, and triggering is most likely in shallow areas. Avoid starting zones.
This problem is classic. Hard to trigger, but when you hit the sweet spot (which you cannot see), full depth avalanches are likely. Don't ski aggressive terrain, the consequences are high so mange your exposure to starting zones very carefully.
Local avalanche forecasters are concerned about this problem, and are calling it a &quot;lurking beast&quot;. Deep slabs that are hard to trigger, but the consequences getting caught are dire. Manage your risk by minimizing exposure to avalanche start zones.
The midpack and basal pack is mostly weak facets and depth hoar. The potential for a full depth avalanche continues to exist if the sweet spot is triggered.

This is the main layer of concern. Full depth avalanches on the basal depth hoar and crust have been occurring every day in the last week. The new snow has added stress to this layer, and will be easiest to trigger this layer in thin snowpack areas.
The mid pack is strengthening in thicker snow pack areas but this means the potential for larger propagations on the weak basal layers is a real concern.  Stick to moderate angled well supported slopes and minimize exposure to large avalanche paths.
Large, deep slabs are occurring naturally and from human triggers. The recent snow has tipped the scale and all avalanche terrain should is suspect. Numerous avalanches have been triggered from long distances away. Avoid avalanche terrain!
The weak snowpack continues to dominate the entire region, and avalanches can be easily triggered in shallow areas at treeline and above. Keep your distance from avalanche starting zones, and work the terrain very carefully to manage your exposure.
&nbsp; A generally weak and faceted snowpack dominates the forecast area. The potential for full depth avalanches exist.
The weak base is the real danger. Moderately angled slopes with thicker snowpack are the best choices for not triggering this layer.
The weak base is the major problem layer in the snowpack. Avalanches will almost certainly involve the entire snowpack.
The forecast snow this weekend may be enough to overload the basal facets in many areas with potential for large slab avalanches. Stick to well supported, planar terrain below 30 degrees and minimize exposure to start zones.
The storm has overloaded the weak and facetted snowpack, and large natural avalanches are being observed. Active deep persistent slab conditions like this are dangerous; avoid avalanche terrain for the next few days - time for good snow in the trees.
The current avalanche cycle is overloading the entire snowpack and many deep avalanches have been observed sliding on the ground. Fracture lines in some areas greater than 150cm deep. The situation is very touchy; avoid all avalanche terrain.
The possibility of natural and skier triggered avalanches remains high. Stay out of avalanche terrain until things settle down. Look for protected skiing in the trees on moderate angled slopes with no exposure to alpine and tree line start zones.
Expect to see less natural activity concerning this layer, however, it is still ripe for human triggering. If triggered, expect large and destructive avalanches with fracture lines up to 200cm deep.
Full depth avalanches have been seen daily on this layer. We expect another natural avalanche cycle on this layer on sunny aspects with the forecasted warm temperatures and sun.
Full depth avalanches continue to be seen daily on this layer. We expect another natural avalanche cycle on this layer on sunny aspects with the forecasted temperatures and sun. Even a cornice release in the heat could trigger a large avalanche.
Watch for daytime warming and areas receiving large amounts of sun. avalanches may run full path and affect valley bottoms and trails crossing avalanche runouts.
Frequency of full depth avalanches on the basal depth hoar/crust is starting to slow down.  Any slope that hasn't avalanched should be treated with caution, as it will be very high consequence if you trigger this layer.
The frequency of full depth avalanches on the basal depth hoar/crust is slowing down, but any slope that has not avalanched should be treated with caution. It will be very high consequence if you trigger this layer.
The weak and unpredictable snowpack persists in the Lake Louise area and eastern side of the forecast region, where all steep terrain remains suspect. This problem is much less prominent west of the Divide, where the snowpack is deeper and stronger.
Thin areas and steep terrain that has not  yet avalanched should be avoided. Thicker moderate angled terrain  with low consequences would be a good choice.
Low likelihood, high consequence. This means the chance of triggering is decreasing, however, if you do, it will be a big slide.
Thin areas will have the biggest potential for triggering the basal depth hoar/crust layer. Caution is advised in steep, planar features. Avalanches will be full depth with large consequences.
Triggering of the basal depth hoar/crust will be most likely from thin snowpack areas. These are harder to trigger now, but if you hit the &quot;sweet spot&quot;, the avalanche will be full depth and large consequence.
In thin snow areas the basal facets are still very weak and producing sudden collapse results in snowpack tests with the potential for large avalanches. Probe often for this weakness near the ground and stick to planar well supported ski slopes.
The weak facets at the base of the snowpack have not gone anywhere. But, time and settlement seem to have brought the snowpack into balance. Isolated, large avalanches may still occur, particularly in areas that have not avalanched previously.
The basal facets are lying dormant for now. However, the possibility of triggering from a weak spot (thin, shallow, rocky area) remains real.
It is a classic Rockies problem of low likelihood, high consequence when dealing with the basal depth hoar/crust. No activity has been seen on this layer in a week, but where the snowpack is thin, your likelihood of triggering a slide will increase.
Although this layer has not been reactive in the last week, the potential to trigger a deep slab from a thin spot remains.
Watch for thin snowpack areas in steeper terrain where triggering the basal depth hoar/crust is possible.
Thin snowpack areas in steep, alpine terrain will be the place to trigger the basal depth hoar/crust.&nbsp;
This problem continues to exist at the base of the snowpack, but triggering is unlikely due to a combination of time, settlement and the bitter cold - all of which have combined to lock up the snowpack. It will reawaken once the weather changes.
A lack of avalanche activity and hard test results show that triggering the weakness at the base of the snowpack is unlikely, however the variability in snowpack depth means it is worth watching for thin areas where triggering may still be possible.&nbsp;
The snowpack has gained some strength and now combined with the cold temperatures it will be hard to trigger an avalanche on the weak layers near the base. This situation will persist until the weather pattern changes.

There has been no avalanches on this layer for two weeks.&nbsp; It is very unlikely this layer will be triggered while we remain in the Arctic high weather system.&nbsp; This layer will wake up again with more snow and wind loading.
The basal layer of depth hoar lies dormant for now, but is a prominent feature of the snowpack. Currently, it will only be possible to trigger from extreme terrain in thin snowpack areas until the weather changes.
The basal depth hoar, crust layer is dormant for now.&nbsp; Currently it is only possible to trigger this layer from extreme terrain in thin snowpack areas.
The basal depth hoar, crust layer is dormant for now. Currently it is only possible to trigger this layer from extreme terrain in thin snowpack areas. This layer will likely become more reactive as we get some new snow loading it.
The deep persistent weakness has been dormant for several weeks. With warming temperatures and increasing snow load may we may begin seeing some avalanches on this layer by Wednesday.
This problem exists in the eastern side of the forecast region (Lake Louise area), and will remain dormant on Wednesday. More snow is needed to re-awaken these facets. Forecasters will be monitoring this problem closely as this week's storm develops.
This dormant layer may start to wake up over the next few days with continued snow and wind loading, we are monitoring it closely. It is a weak basal facet layer that is a problem on the East side of the Divide (Lake Louise area).
The basal depth hoar has been gaining strength and is lying dormant. We are waiting to see if this layer ``wakes up`` in thin snowpack areas this weekend with the new snow load.
In thinner snowpack areas, many avalanches are initiating as a storm or persistent slab and are stepping down to this layer.
The ground level weakness of facets and depth hoar appears to have woken up, and the main avalanche problem right now is occasional large avalanches failing on the ground. Avoid, or carefully select any large steep slopes at treeline or above.
We have seen isolated activity on depth hoar and facets located near the base of the snowpack in thin areas mainly E of the divide. The main problem right now is triggering the occasional large avalanche that fails on the ground. 
Very low confidence in this basal layer of depth hoar as daily avalanches size 2-3 and large whumphs continue to be reported. Mainly a problem on the East side of the Continental Divide or in shallower snowpacks in Kootenay Park.
Thin areas mainly E of the divide are still susceptible to triggering basal layers causing larger avalanches. Big triggers such as cornice failures could be enough load to trigger an avalanche on the ground level
Thin areas mainly E of the divide are still susceptible to triggering basal layers causing larger avalanches. Big triggers such as cornice failures could be enough load to trigger an avalanche on the ground level.
With warming temperatures we expect to see an increase in avalanche activity on our deep facet layers especially in thinner snowpack areas or in places where a cornice fall could act as a large trigger. Minimize exposure to large slopes.
The warmer temperatures have the potential to wake this layer up, as demonstrated today on Cascade Waterfall (size 3).
Daytime warming in thinner snowpack areas or larger triggers such as cornices may trigger this weakness. Thin rocky snowpack areas may also be susceptible to skier triggering.
Although conditions are improving, it is still a good idea to avoid large, steep (&gt;35 degree) slopes in areas where the total snowpack depth is &lt;200cm. Use your probe and to check for snowpack depth and strength.
Colder weather will add a little more stability to the snowpack. It is still too early to move out onto big alpine lines.
Triggering this layer is most likely during warm periods and from thin rocky locations. Large triggers such as cornices may also trigger this deep weakness. This hazard will gradually increase as temperatures warm up over the next few days.
The big question for this avalanche problem is heat. Under current cool conditions it is nearly dormant. However, when we receive the first real blast of heat...pay attention.
This problem seems to have calmed down in the last week, but we remained concerned and expect&nbsp; to see more of these avalanches when the temperatures warm up again.
The primary problem in the snowpack is the interface between the recent storm snow and the November 6th and 24th facet/crust interfaces. This is the problem responsible for the majority of the avalanches in the past week. Watch for remote triggers.

The primary problems in the snowpack are the Nov. 6th and 24th facet/crust interfaces. These layers are most reactive in alpine/ treeline areas where the wind has slabbed up the surface snow.
Snowpack tests continue to show collapse at several levels of weak facets near the base of the snowpack.  Avoid large slopes during this warm spell; wait for future cooling when the snowpack will stabilize and conditions will improve.

While the cold temperatures have stabilized the snowpack temporarily, it's overall structure remains weak. Travel under and beside avalanche paths is reasonable, but continue to avoid or be very careful when touching any avalanche start zones.

Many avalanche paths have already slid in the 2,400 m - 2,800 m range. Slopes that have not failed are expected to fail with the increased snow loading and winds this weekend.
New snow will likely overload deep weaknesses in the snowpack causing increased avalanche activity.
In many areas, the basal facet weakness has been avalanched away, where this has not happened, there is a lot of snow sitting on top of this unstable weakness.
Triggering any of the above problems have potential to initiate this layer and create large full path avalanches.
This layer is proving very susceptible to human triggering as evidenced by the two remotely triggered slides today. Extensive whumphing and cracking experienced particularly at treeline elevations.
Warmer temperatures will contribute to overloading the weak basal facets leading to full depth avalanches in the valley bottoms. Be cautious of steep slopes along terrain traps such as creeks.
Depending on elevation, this layer is either bridged by a hard mid-pack at higher elevations and likely to be triggered from a shallow area. At the lower elevations there is minimal support in the snowpack and is easier to trigger.
Basal weakness means that the potential for full depth avalanches still exists.&nbsp; Smaller avalanches have the potential to trigger deeper instabilities.
The basal facet layer is of great concern as it is&nbsp; the most significant weakness in this year's snowpack.  Use extra caution in areas that have not previously avalanched, especially on open treeline slopes.
The basal facets are weaker below tree line as many whumphs noted. Where the snow is deeper at higher elevations, the mid-pack is bridging the weak basal facets; however, snowpack depth varies so much that its hard to inspire confidence in stability.

Snowpack depth is highly variable. It might be hard to spot the shallow areas where triggering this deeply buried weak snow is more likely. Large loads such as falling cornices or surface avalanches also have the potential to wake up these slabs
Be conservative with your terrain selection and consider steep or unsupported planar slopes carefully. Assess the snowpack often: the variable nature of the snowpack makes it hard to avoid shallow areas where triggering may be more likely.

Be conservative with your terrain selection and assess steep or unsupported planer slopes carefully where the snowpack may be thin. In these areas it may be possible to trigger the weak faceted area created early in the winter.
30 cm above the ground, this weak snow is a serious concern. Travelers should carefully consider snowpack depth, terrain shape, and slope angle. Use your probe to confirm depths when you are uncertain.

However, large and destructive avalanches may be possible with a heavy load in steep, thin start zones.</span><span class="s_AA239
This weak snow under the entire snowpack remains a concern especially in thin areas. As warming and loading occurs, avalanches described in the problems above could provide a large load triggering larger events on this layer.
With widespread avalanches occurring the potential for the weak snow at the bottom of the snowpack to be triggered as a large avalanche is elevated. Give big terrain a wide berth until things have a chance to settle.
The slab of well settled snow that protects the weak snow at the base of snowpack is not very thick in many areas. As the storms continue to place stress on the snowpack, and with significant surface avalanches expected, larger events could occur.
Do not forget that there is weak snow under the entire snowpack. In shallow areas this faceted snow has continued to weaken and the slab above it that is holding the snowpack together has become stressed by recent loading.

The chance of triggering the deep weak layers from early February are diminishing but these layers have not completely disappeared. Any slope that have not slid should be suspect for possible large destructive avalanches.
As the snowpack cools this week it is gaining strength. The weak layer from early Feb may still be an issue but this is likely limited to thin areas at higher elevations under current conditions.
This weak faceted layer from early Feb may still be an issue in isolated thin and high elevation locations. With the changing weather in the next few days, snow is likely to be moving: a falling cornice or small avalanche could trigger this layer.
The lower layers of the snowpack remain weak in many areas but are most likely to be triggered by a large load such as a cornice or smaller avalanche in thin areas at high elevations.
Weak snow deep in the snowpack should be kept on the radar for those traveling to more exposed places. A large load such as a cornice fall or significant and sustained heating may wake this problem up in many locations in the near future.
At high elevations cooler temps will have only allowed thin crusts to form above the weak November Facets which may remain a possibility for triggering for some time. Use caution until more is know about alpine areas.

These layers from early season are still a concern on N aspects in the alpine, especially in shallow snowpack areas. Warm temperatures and rain penetrating the snowpack could wake up these deep instabilities.

Facets atop a deeply buried crust produced large avalanches in neighboring areas lately, and are giving Sudden results in tests. The strength of this layer is highly variable across terrain, so a conservative approach to wide-open terrain is crucial.
Facets atop a deeply buried crust produced large avalanches in recent weeks, and are giving Sudden results in tests. The strength of this layer is highly variable across terrain, so a conservative approach to big terrain is crucial.
Facets sit atop at crust buried around a meter deep. This layer generally requires large triggers, but will increase in sensitivity during periods of warm temperatures. Another persistent weak layer still exists about 50cm deep in isolated areas
Weak faceted layers from previous cold temps in the mid and lower snowpack remain a concern, particularly in shallow snowpack areas where facetting is more pronounced and triggering is more likely.
Due to the depth of the weak layers, trigger points are isolated but the consequence would be high. Shallow areas, rocky areas, and areas with Variable snowpack depth should be avoided. This problem may also exist Below Treeline in the Front Ranges.

Although it has been several weeks since natural activity was last seen on the deeply buried December Facets / November Crust, the consequences of triggering a large avalanche from just the wrong shallow, faceted spot, could be dire.
Deeply buried Persistent weak layers from a cold winter have produced few results in recent testing, but are now being heavily loaded. In sheltered/windward terrain, this is the first large load on these layers. Avoid previously shallow areas.

Several large avalanches have been observed from previously shallow terrain, where storm snow fell on large facets.  Observations have been limited; it is possible that Persistent slabs may be triggered in deeper areas also.

There is uncertainty about the distribution of this layer, it is suspected to be most reactive at Treeline, on steep S and SW aspects where facets overlie a crust.
Significant snowfall accumulations from the past month are currently stressing the middle and lower snowpack.  Persistent weak layers will be further tested as the temperatures rise in to the middle of the week.
Significant ongoing snowfall accumulations, combined with sustained warm temperatures are currently stressing facets in the lower snowpack, and a crust in the mid snowpack.
Significant ongoing snowfall accumulations, combined with sustained warm temperatures are currently stressing facets in the lower snowpack, and a crust in the mid snowpack.
Recent warm temperatures &amp; heavy snowfall has added stress to facets in the lower snowpack, and a crust in the mid snowpack that may have overlying facets in isolated areas. It will take days for temperatures to cool deep within the snowpack.
A crust down 1m (to Treeline, and higher on solar aspects) and Facets in the bottom 1/3rd of the snowpack, are slowly adjusting to recent heavy loading. Human triggering of large, destructive avalanches remains Possible, in the wrong terrain.
A crust down 1m (up to Treeline, and higher on solar aspects), and Facets in the bottom 1/3rd of the snowpack, are persisting as weak layers to be respected. These could be triggered by cornice falls, or by human triggered in isolated areas.
Facets in the bottom 1/3rd of the snowpack are persisting as a weak layer to be respected. These could easily be triggered by cornice falls, or by the weight of a person in isolated areas.
Cornices are large and continue to build with warm temps and wind. Incoming rain/snow on Friday may be the trigger that causes cornices to fail, which may in turn trigger deep persistent weak layers in large open terrain.
The first sustained warming event of the season will put the deeply buried December Facet layer to the test. The 'where' and 'when' of this problem is difficult to evaluate, but likelihood will rise with the sustained warm temps forecast.
The deep mid-November crust appears to be waking up and several avalanches have recently released down 200 cm in the snowpack.  Conservative terrain selection is critical while the alpine snowpack is warmed for the first time this winter.
We had one report of a deep persistent slab avalanche size 3.5 at Mt Harmer that released during the storm. Terrain with similar exposure to the wind and a shallow weak snowpack may behave in the same manner.

The cold has started to break down the midpack at all elevations which helps limit the size of avalanches. However, significant avalanches are still a possibility due to the entire snowpack being involved. Treat large terrain features with respect.
Stiff windslabs are the main concern at this time.&nbsp; These slabs may be triggerred from a thin snowpack area so pay attention to snow distribution as you travel.
Stiff wind slabs still exist throughout the forecast area and these sit on the weak basal facets. Though difficult to trigger, this weakness could produce large avalanches. Thin snowpack areas are a potential trigger point.
The basal weakness remains, and incoming snow and wind may lead to a re-awakening of this problem. Large terrain features should be avoided.
Its unlikely that this new snow will re-awaken the basal weak layers but keep it in your mind that it will be tougher for you to see the thin weak areas where it may be triggerred by you!
The new load is a concern with this layer. Forecasters are unsure of how the basal layers will handle the rapid load. LOTS of whumphing and cracking on those lower layers today. Assess snowpack depth by probing to get a feel for what's beneath you.
We havent seen any action on the Basal facets in sometime now but remember that this weakness persists down low in the snowpack.

An avalanche that is initiated in the upper snowpack could step down to the basal weak layers.
Slab failures are sometimes stepping down to the November rain crust.
Facets overlying the Nov 6th crust are still producing whumpfs and settlements indicating that this layer is still possible for skiers to trigger.
The Nov crust is beginning to facet out in some areas but still use caution and evaluate this deep weakness.
Thin spots, heavily wind loaded features and steep rocky terrain are areas where the Nov6th will be a bigger problem. Dig down to assess the crust and its reactivity if in question.
This layer has been the main sliding layer over the past week.&nbsp; Expect any new slides to step down to this layer.
A layer of facets overlying the 1106CR has been responsible for many avalanche over the past week.&nbsp; Did down and evalulate this interface as you travel.
Recent warming has created a more cohesive slab over the November rain crust. Stability tests today indicate that human-triggering is likely.
Slabs are sitting on a weak basal combination of facets overtop of the November rain crust. Wide propagations and more sensitive triggering are now possible due to the recent increase in slab density.
Rain and warm temps have the potential to wake up this basal layer.
At higher elevations, there's still a significant amount of snow resting on this layer waiting for a trigger. Avoid avalanche terrain until the weather cools and stabilizes the snowpack.
A layer of facets over this weakness will be most easily triggerred from a thinner snowpack area.
The basal weakness will plague the snowpack for some time. This problem is likely more triggerable in the Alpine at the moment, due to recent re-freezing of a rain-soaked snowpack at lower elevations.
Be cautions around thin snow pack areas
The weak basal layers are the principal concern in the snowpack. Dense slabs now overlie these basal layers. While these dense slabs provide some bridging strength, if a slab is triggered the consequences could be significant.
We are relying on the dense midpack to shield us from a failure of the Nov 6th. In shallow areas, the likelihood of triggering the deep layer rises dramatically. Probe to confirm snow depths as you approach bigger terrain.
="s_3FE45715">The likelihood of triggering a deep persistent slab has decreased but the consequences remain very high. Be wary of any slopes that did not release during the storms. Heavy triggers such cornice falls may be able to trigger a deep weak layer.

The consistently warm temps are preserving the midpack right now. The mid layers are what's keeping the hazard at a moderate level. Before committing to bigger terrain, assess these layers and be sure the strength is there.
Two weak layers remain a concern: an old rain crust near the bottom and a facet layer in the middle of the snowpack. Triggering these layers is unlikely but the consequences remain very high. Be wary of slopes that did not release during the storms.

This is still the main concern right now. Choose terrain that is supported and in a deeper snowpack. We are definitely dealing with a classic Rockies snowpack right now!

In big terrain this is a serious concern. Variable depth snowpacks and terrain with large, potential triggers should be avoided. Avoid exposure to avalanche runout zones.
Deep persistent weaknesses recently woke up with the warm temperatures and should be treated with suspicion until after things freeze up again. Although likely to need a large trigger, the potential consequences are dire.

Avalanches in the upper snowpack will likely step down to a deeper layer such as the Jan 30th or the Nov 6th or the weak basal facets.
The re-freeze has begun, and the likelihood of triggering a deeply buried weak layer should reduce as the freezing continues. Daytime heating, strong solar radiation, or cornice falls could trigger deep weak layers.
The re-freeze has begun, and should reduce the likelihood of triggering deep persistent weak layers. The deeply buried crust may continue to be triggered by large loads like cornice falls.
Although unlikely, these highly destructive avalanches remain possible with heavy impacts (e.g. cornice falls and surface avalanche stepping down) in the right spot (e.g. thin rocky areas). Daytime warming will also increase sensitivity.
This problem commands a lot of respect. Avalanches stepping down can entrain large amounts of snow right now making for large destructive avalanches. Large triggers should be a concern right now.
As the upper layers gain strength through the cooling process, we can expect this layer to settle down and become less active. Having said that, remember that thin spots can be problematic. Large triggers are still a concern.
Although unlikely, these highly destructive avalanches remain possible with heavy impacts (e.g. cornice falls and surface avalanche stepping down) in the right spot (e.g. thin rocky areas). Daytime warming will also increase sensitivity.
Thin areas, and paths that have not avalanched during the cycle are more likely to have this problem.
The natural cycle a few days ago seems to have cleaned out many start zones. Thin and/or variable start zones with no previous activity are worth some thought and consideration.
Weak basal layers are prominent throughout the forecast area. While the probability of triggering the basal layers is less likely, the consequences are large.
Keep an eye out for cornices as possible large triggers, especially when the sun comes out and the temps begin to rise.&nbsp; This basal weakness is still on our radar.
As our snowpack slowly grows it becomes easy to forget about the bottom layers. Remember that the bottom is still weak in many places and requires a deep snowpack to safely bridge the bottom layers.
Large triggers have recently impacted this layer in variable depth terrain. Watch for a weak snowpack in alpine areas and anticipate where the thin areas might be. Probing is a valuable tool to figure out snow depth trends.
The ground cover and elevation seem to be a factor here. This layer is much more prominent in high rocky terrain, where the depth hoar is more persistent and slow to change. Assess these transitional zones and watch for trends as you travel.
This is a very low probability problem with large consequences. A weak basal layer resulted in several full depth avalanches during the last sunny period which could be repeated this weekend. Avoid steep sun exposed slopes during the afternoon.

Some recent cornice triggered avalanches show us that big triggers can easily hit the deeper layers and cause a slide. Be to sure to assess overhead terrain from a potential triggering perspective
This problem presents as a layer of depth hoar at the base of the snowpack. To get this going we need either a large trigger or to hit the shallow &quot;sweet spot&quot; while skiing. Steep, shallow areas with a hard slab on top should be treated with caution.

The weak basal layers are still prominent in the forecast area. The probability of triggering this deep weakness is low, but the resulting avalanches could be very large. Large triggers such as cornices could trigger this weakness.
The probability of triggering this basal weakness is low, but if the trigger is large enough such as a cornice, the resulting avalanche will be quite large.
This layer still lingers in shallow areas. As the midpack facets more and more, it will lose its bridging properties making it easier to trigger the deeper layers. Watch for this situation in thin snowpack areas especially.
This may be more of a concern at treeline where windslabs have become softer due to facetting.
It will take a significant trigger, or a shallow spot to initiate the deeper layers right now. Watch snow depths as you travel and stick to the deeper areas. Especially as you enter your line.
We've officially hit the low probability, high consequence stage with this layer. Steep terrain with exposed rocks and a shallow snow pack are a considered a trouble area. Treat these areas with caution.
With the forecasted mild temps in the alpine, be aware of the strong effect of the sun this time of year should it appear. Large triggers such as cornices will weaken and could trigger this basal weakness.
Steep and shallow snowpack terrain should still be considered suspect. A skier triggered avalanche occurred yesterday on a steep solar aspect in the alpine.
Shallow snowpack areas that are steep should be treated with respect. These features are the most likely to steep down to basal weak layers and produce a full-depth avalanche. Large triggers such a s cornices are also a concern.
The basal weak layers ares still a concern in steep alpine terrain, especially in shallow snowpack areas. Large triggers, such as cornices, may also be enough to wake up this deep persistent weak layer.
As the snowpack warms up, remember that this layer will be easier to trigger. Cornices, loose wet, wet slabs are all potential triggers at this point.
We have concerns about this problem &quot;waking up&quot; with warm temperatures. A crust that previously isolated deep weaknesses has broken down with warming. Recent whumpfing indicates unstable snow.
It is unlikely to trigger this layer, but in steep convex terrain there is enough potential to keep it on the list. Large triggers are also something to think about. Cornices may be likely trigger.
We have concerns about this problem &quot;waking up&quot; with warm temperatures. A crust that previously isolated deep weaknesses has broken down with warming. Recent whumpfing indicates unstable snow.
New snow and/or rain load may be enough to wake this layer up again. Avoid any exposure to large overhead terrain if the forecast holds true. New, weak cornices are something to think about as a potential trigger.

Weak layers at the base of the snowpack may still be triggerred from variable or thin snowpack areas.
Several days of warming followed by rain up to alpine elevations may result in avalanches releasing down to persistent weak layers. Avalanches releasing or stepping down to deeply buried weak layers may result in large destructive avalanches.
The basal weak layers remain a concern and could &quot;wake up&quot; with the new load of snow forecast for Sunday night. Shallow snowpack areas are particularly concerning in this respect.
Recent very warm temperatures followed by heavy rain, and then the forecast snow and wind, may be too much change for the snowpack to manage. Avalanches releasing on the deeply buried weak layers are expected to be large and destructive.
Recent loading may make the basal weaknesses more sensitive, especially in shallow snowpack features.
The recent new load of snow could be enough to awaken the basal weak layers, particularly in shallow snowpack areas.

No activity on this layer in some time, but its still in forecasters minds.
The basal weak layers have been dormant for some time, but the potential remains for a low probability, high consequence event due to the structure of the snowpack. Be mindful of this issue in shallow snowpack regions and when the snowpack warms up.

Basal facets and the Jan 6th FC interface are likely to be triggerred from thinner snowpack areas.
We may sound like a broken record but its critical you probe with your pole in the alpine making sure you can discern shallow and rocky snowpack areas where triggering the facets from January in a big alpine terrain feature is still very possible.
This layer is starting to get our attention again. As the new treeline snow settles, the burial depth is staying relatively constant at 1m. Keep an eye on where thin spots may be present and avoid shallow areas at all elevations.

The base of the snowpack is still quite weak with the Oct melt freeze crust and basal facets still providing good sliding layers under the right conditions. Probe often for basal weaknesses and use caution in steeper terrain.
20-25cm of storm snow combined with mild temperatures and wind may start causing failures in the deeper basal facets or on the Oct melt freeze crust. Use caution in steep terrain.

At this time all steep slopes have the potential to step down to the basal facets and result in large avalanches. The snow depth is quite variable across the forecast region, and triggering is most likely in shallow areas. Avoid starting zones.
This problem is classic. Hard to trigger, but when you hit the sweet spot (which you cannot see), full depth avalanches are likely. Don't ski aggressive terrain, the consequences are high so mange your exposure to starting zones very carefully.
Local avalanche forecasters are concerned about this problem, and are calling it a &quot;lurking beast&quot;. Deep slabs that are hard to trigger, but the consequences getting caught are dire. Manage your risk by minimizing exposure to avalanche start zones.
The midpack and basal pack is mostly weak facets and depth hoar. The potential for a full depth avalanche continues to exist if the sweet spot is triggered.
Recent snow &amp; wind loading has resulted in a few slides size 2-3 failing to ground. Avalanche professionals in the Louise area went for a ride today after placing 7 explosives in a feature then ski cutting it &amp; hitting the hidden mine to trigger it.
This is the predominant layer in the snowpack, and full depth avalanches to ground have been observed daily over the past week. This will increase in frequency with the new snow.
This is the main layer of concern. Full depth avalanches to ground have occurred daily over the past week. This layer will be stressed further by tonight's storm increasing it's sensitivity to natural and human triggering.
This is the main layer of concern. Full depth avalanches on the basal depth hoar and crust have been occurring every day in the last week. The new snow has added stress to this layer, and will be easiest to trigger this layer in thin snowpack areas.
The mid pack is strengthening in thicker snow pack areas but this means the potential for larger propagations on the weak basal layers is a real concern.  Stick to moderate angled well supported slopes and minimize exposure to large avalanche paths.
Large, deep slabs are occurring naturally and from human triggers. The recent snow has tipped the scale and all avalanche terrain should is suspect. Numerous avalanches have been triggered from long distances away. Avoid avalanche terrain!
The weak snowpack continues to dominate the entire region, and avalanches can be easily triggered in shallow areas at treeline and above. Keep your distance from avalanche starting zones, and work the terrain very carefully to manage your exposure.
&nbsp; A generally weak and faceted snowpack dominates the forecast area. The potential for full depth avalanches exist.
The weak base is the real danger. Moderately angled slopes with thicker snowpack are the best choices for not triggering this layer.
The weak base is the major problem layer in the snowpack. Avalanches will almost certainly involve the entire snowpack.
The forecast snow this weekend may be enough to overload the basal facets in many areas with potential for large slab avalanches. Stick to well supported, planar terrain below 30 degrees and minimize exposure to start zones.
The storm has overloaded the weak and facetted snowpack, and large natural avalanches are being observed. Active deep persistent slab conditions like this are dangerous; avoid avalanche terrain for the next few days - time for good snow in the trees.
The current avalanche cycle is overloading the entire snowpack and many deep avalanches have been observed sliding on the ground. Fracture lines in some areas greater than 150cm deep. The situation is very touchy; avoid all avalanche terrain.
The possibility of natural and skier triggered avalanches remains high. Stay out of avalanche terrain until things settle down. Look for protected skiing in the trees on moderate angled slopes with no exposure to alpine and tree line start zones.
Expect to see less natural activity concerning this layer, however, it is still ripe for human triggering. If triggered, expect large and destructive avalanches with fracture lines up to 200cm deep.
Full depth avalanches have been seen daily on this layer. We expect another natural avalanche cycle on this layer on sunny aspects with the forecasted warm temperatures and sun.
Full depth avalanches continue to be seen daily on this layer. We expect another natural avalanche cycle on this layer on sunny aspects with the forecasted temperatures and sun. Even a cornice release in the heat could trigger a large avalanche.
Watch for daytime warming and areas receiving large amounts of sun. avalanches may run full path and affect valley bottoms and trails crossing avalanche runouts.
Frequency of full depth avalanches on the basal depth hoar/crust is starting to slow down.  Any slope that hasn't avalanched should be treated with caution, as it will be very high consequence if you trigger this layer.
The frequency of full depth avalanches on the basal depth hoar/crust is slowing down, but any slope that has not avalanched should be treated with caution. It will be very high consequence if you trigger this layer.
The weak and unpredictable snowpack persists in the Lake Louise area and eastern side of the forecast region, where all steep terrain remains suspect. This problem is much less prominent west of the Divide, where the snowpack is deeper and stronger.
Thin areas and steep terrain that has not  yet avalanched should be avoided. Thicker moderate angled terrain  with low consequences would be a good choice.
Low likelihood, high consequence. This means the chance of triggering is decreasing, however, if you do, it will be a big slide.
Thin areas will have the biggest potential for triggering the basal depth hoar/crust layer. Caution is advised in steep, planar features. Avalanches will be full depth with large consequences.
Triggering of the basal depth hoar/crust will be most likely from thin snowpack areas. These are harder to trigger now, but if you hit the &quot;sweet spot&quot;, the avalanche will be full depth and large consequence.
In thin snow areas the basal facets are still very weak and producing sudden collapse results in snowpack tests with the potential for large avalanches. Probe often for this weakness near the ground and stick to planar well supported ski slopes.
The weak facets at the base of the snowpack have not gone anywhere. But, time and settlement seem to have brought the snowpack into balance. Isolated, large avalanches may still occur, particularly in areas that have not avalanched previously.
The basal facets are lying dormant for now. However, the possibility of triggering from a weak spot (thin, shallow, rocky area) remains real.
It is a classic Rockies problem of low likelihood, high consequence when dealing with the basal depth hoar/crust. No activity has been seen on this layer in a week, but where the snowpack is thin, your likelihood of triggering a slide will increase.
Although this layer has not been reactive in the last week, the potential to trigger a deep slab from a thin spot remains.
This problem continues to exist at the base of the snowpack, but triggering is unlikely due to a combination of time, settlement and the bitter cold - all of which have combined to lock up the snowpack. It will reawaken once the weather changes.
A lack of avalanche activity and hard test results show that triggering the weakness at the base of the snowpack is unlikely, however the variability in snowpack depth means it is worth watching for thin areas where triggering may still be possible.&nbsp;
The snowpack has gained some strength and now combined with the cold temperatures it will be hard to trigger an avalanche on the weak layers near the base. This situation will persist until the weather pattern changes.
The snowpack has gained some strength and now combined with the cold temperatures it will be hard to trigger an avalanche on the weak layers near the base. This situation will persist until the weather pattern changes.
There has been no avalanches on this layer for two weeks.&nbsp; It is very unlikely this layer will be triggered while we remain in the Arctic high weather system.&nbsp; This layer will wake up again with more snow and wind loading.
We have seen the basal facets wake up at lower elevations in the Kootenay area. This may not be widespread, but will cause large avalanches if initiated.
With the cooling temperatures this will become less reactive to skier traffic. Large triggers such as cornice drops or large slab releases could still cause failures on the basal facets.
In thinner snowpack areas, many avalanches are initiating as a storm or persistent slab and are stepping down to this layer.
The ground level weakness of facets and depth hoar appears to have woken up, and the main avalanche problem right now is occasional large avalanches failing on the ground. Avoid, or carefully select any large steep slopes at treeline or above.
We have seen isolated activity on depth hoar and facets located near the base of the snowpack in thin areas mainly E of the divide. The main problem right now is triggering the occasional large avalanche that fails on the ground. 
Very low confidence in this basal layer of depth hoar as daily avalanches size 2-3 and large whumphs continue to be reported. Mainly a problem on the East side of the Continental Divide or in shallower snowpacks in Kootenay Park.
Thin areas mainly E of the divide are still susceptible to triggering basal layers causing larger avalanches. Big triggers such as cornice failures could be enough load to trigger an avalanche on the ground level
Thin areas mainly E of the divide are still susceptible to triggering basal layers causing larger avalanches. Big triggers such as cornice failures could be enough load to trigger an avalanche on the ground level.
With warming temperatures we expect to see an increase in avalanche activity on our deep facet layers especially in thinner snowpack areas or in places where a cornice fall could act as a large trigger. Minimize exposure to large slopes.
The warmer temperatures have the potential to wake this layer up, as demonstrated today on Cascade Waterfall (size 3).
Daytime warming in thinner snowpack areas or larger triggers such as cornices may trigger this weakness. Thin rocky snowpack areas may also be susceptible to skier triggering.
Although conditions are improving, it is still a good idea to avoid large, steep (&gt;35 degree) slopes in areas where the total snowpack depth is &lt;200cm. Use your probe and to check for snowpack depth and strength.
Colder weather will add a little more stability to the snowpack. It is still too early to move out onto big alpine lines.
Triggering this layer is most likely during warm periods and from thin rocky locations. Large triggers such as cornices may also trigger this deep weakness. This hazard will gradually increase as temperatures warm up over the next few days.
The big question for this avalanche problem is heat. Under current cool conditions it is nearly dormant. However, when we receive the first real blast of heat...pay attention.
This problem seems to have calmed down in the last week, but we remained concerned and expect&nbsp; to see more of these avalanches when the temperatures warm up again.
The primary problem in the snowpack is the interface between the recent storm snow and the November 6th and 24th facet/crust interfaces. This is the problem responsible for the majority of the avalanches in the past week. Watch for remote triggers.

The primary problems in the snowpack are the Nov. 6th and 24th facet/crust interfaces. These layers are most reactive in alpine/ treeline areas where the wind has slabbed up the surface snow.
Snowpack tests continue to show collapse at several levels of weak facets near the base of the snowpack.  Avoid large slopes during this warm spell; wait for future cooling when the snowpack will stabilize and conditions will improve.

While the cold temperatures have stabilized the snowpack temporarily, it's overall structure remains weak. Travel under and beside avalanche paths is reasonable, but continue to avoid or be very careful when touching any avalanche start zones.

Many avalanche paths have already slid in the 2,400 m - 2,800 m range. Slopes that have not failed are expected to fail with the increased snow loading and winds this weekend.
New snow will likely overload deep weaknesses in the snowpack causing increased avalanche activity.
In many areas, the basal facet weakness has been avalanched away, where this has not happened, there is a lot of snow sitting on top of this unstable weakness.
Triggering any of the above problems have potential to initiate this layer and create large full path avalanches.
This layer is proving very susceptible to human triggering as evidenced by the two remotely triggered slides today. Extensive whumphing and cracking experienced particularly at treeline elevations.
Warmer temperatures will contribute to overloading the weak basal facets leading to full depth avalanches in the valley bottoms. Be cautious of steep slopes along terrain traps such as creeks.
Depending on elevation, this layer is either bridged by a hard mid-pack at higher elevations and likely to be triggered from a shallow area. At the lower elevations there is minimal support in the snowpack and is easier to trigger.
Basal weakness means that the potential for full depth avalanches still exists.&nbsp; Smaller avalanches have the potential to trigger deeper instabilities.
The basal facet layer is of great concern as it is&nbsp; the most significant weakness in this year's snowpack.  Use extra caution in areas that have not previously avalanched, especially on open treeline slopes.
The basal facets are weaker below tree line as many whumphs noted. Where the snow is deeper at higher elevations, the mid-pack is bridging the weak basal facets; however, snowpack depth varies so much that its hard to inspire confidence in stability.

The February deep instability, down1.5m-2m will need a large trigger to be initiated. Although the sudden snow loading has ended, it may get triggered by a large cornice for or from a shallower avalanche.
The deep instability from mid February , down around 2m will need a large trigger to be initiated like a cornice fall or shallower avalanche. It should not be overlooked by backcountry users due to the  large consequences should it be triggered.
In Rogers Pass, the Feb 10 surface hoar/crust sandwich is buried over 2m deep. We are still seeing hard, sudden test results on this layer. If a very large trigger smacks the slope, there is the potential for a huge avalanche.
The late Jan/early Feb persistent weak layer is still active. Very large and impressive avalanches have been triggered by rapid loading during storms, avalanche control, and skiers remotely triggering (fortunately in a safe spot) from shallow areas.
The deepest instability within our snowpack is down around 2m. Large triggers have produced very big avalanches on this layer into last week. It remains on our watch list, and it's another reason to avoid shallow snowpack areas.

Buried crust layers exist at all elevations. At 2000m these are limited to basal layers which are starting to show signs of growing weak crystals. Thin areas will be of concern where cool temperatures can penetrate and triggering is more likely.
This weak layer of snow persists 30 to 40 cm above the ground. Triggering a wind slab could produce the large load necessary to wake this layer up. Use caution in thin areas particularly with steep, planar, or unsupported slopes.

In shallow snowpack areas there is a possibility that the deeper instabilities could be triggered. Our growing snowpack and milder temperatures are helping to reduce the chance that this layer could be triggered in most areas.

Snowpack depth is highly variable. It might be hard to spot the shallow areas where triggering this deeply buried weak snow is more likely. Large loads such as falling cornices or surface avalanches also have the potential to wake up these slabs
Be conservative with your terrain selection and consider steep or unsupported planar slopes carefully. Assess the snowpack often: the variable nature of the snowpack makes it hard to avoid shallow areas where triggering may be more likely.
Be conservative with your terrain selection and assess steep or unsupported planar slopes carefully. The new snow may be hiding shallow areas where triggering may be more likely and with the variability in snowpack there are many thin areas.
Be conservative with your terrain selection and assess steep or unsupported planer slopes carefully where the snowpack may be thin. In these areas it may be possible to trigger the weak faceted area created early in the winter.
30 cm above the ground, this weak snow is a serious concern. Travelers should carefully consider snowpack depth, terrain shape, and slope angle. Use your probe to confirm depths when you are uncertain.

This weak snow under the entire snowpack remains a concern especially in thin areas. As warming and loading occurs, avalanches described in the problems above could provide a large load triggering larger events on this layer.
With widespread avalanches occurring the potential for the weak snow at the bottom of the snowpack to be triggered as a large avalanche is elevated. Give big terrain a wide berth until things have a chance to settle.
The slab of well settled snow that protects the weak snow at the base of snowpack is not very thick in many areas. As the storms continue to place stress on the snowpack, and with significant surface avalanches expected, larger events could occur.
Do not forget that there is weak snow under the entire snowpack. In shallow areas this faceted snow has continued to weaken and the slab above it that is holding the snowpack together has become stressed by recent loading.

The chance of triggering the deep weak layers from early February are diminishing but these layers have not completely disappeared. Any slope that have not slid should be suspect for possible large destructive avalanches.
At high elevations cooler temps have only allowed thin crusts to form above the weak November Facets which may remain a possibility for triggering for some time. Use caution TL and above especially in thin or variable areas.

Facets atop a deeply buried crust produced large avalanches in neighboring areas lately, and are giving Sudden results in tests. The strength of this layer is highly variable across terrain, so a conservative approach to wide-open terrain is crucial.

Facets sit atop at crust buried around a meter deep. This layer generally requires large triggers, but will increase in sensitivity during periods of warm temperatures. Another persistent weak layer still exists about 50cm deep in isolated areas
Facets sit atop at crust buried up to a meter deep. This layer generally requires large triggers, but may increase in sensitivity during periods of warm temperatures.
Weak faceted layers from previous cold temps in the mid and lower snowpack remain a concern, particularly in shallow snowpack areas where facetting is more pronounced and triggering is more likely.
Due to the depth of the weak layers, trigger points are isolated but the consequence would be high. Shallow areas, rocky areas, and areas with Variable snowpack depth should be avoided. This problem may also exist Below Treeline in the Front Ranges.

Although it has been several weeks since natural activity was last seen on the deeply buried December Facets / November Crust, the consequences of triggering a large avalanche from just the wrong shallow, faceted spot, could be dire.
Deeply buried Persistent weak layers from a cold winter have produced few results in recent testing, but are now being heavily loaded. In sheltered/windward terrain, this is the first large load on these layers. Avoid previously shallow areas.

Several large avalanches have been observed from previously shallow terrain, where storm snow fell on large facets.  Observations have been limited; it is possible that Persistent slabs may be triggered in deeper areas also.

There is uncertainty about the distribution of this layer, it is suspected to be most reactive at Treeline, on steep S and SW aspects where facets overlie a crust.
Significant snowfall accumulations from the past month are currently stressing the middle and lower snowpack.  Persistent weak layers will be further tested as the temperatures rise in to the middle of the week.
Significant ongoing snowfall accumulations, combined with sustained warm temperatures are currently stressing facets in the lower snowpack, and a crust in the mid snowpack.

Recent warm temperatures &amp; heavy snowfall has added stress to facets in the lower snowpack, and a crust in the mid snowpack that may have overlying facets in isolated areas. It will take days for temperatures to cool deep within the snowpack.
A crust down 1m (to Treeline, and higher on solar aspects) and Facets in the bottom 1/3rd of the snowpack, are slowly adjusting to recent heavy loading. Human triggering of large, destructive avalanches remains Possible, in the wrong terrain.
A crust down 1m (up to Treeline, and higher on solar aspects), and Facets in the bottom 1/3rd of the snowpack, are persisting as weak layers to be respected. These could be triggered by cornice falls, or by human triggered in isolated areas.
Facets in the bottom 1/3rd of the snowpack are persisting as a weak layer to be respected. These could easily be triggered by cornice falls, or by the weight of a person in isolated areas.
Cornices are large and continue to build with warm temps and wind. Incoming rain/snow on Friday may be the trigger that causes cornices to fail, which may in turn trigger deep persistent weak layers in large open terrain.
The first sustained warming event of the season will put the deeply buried December Facet layer to the test. The 'where' and 'when' of this problem is difficult to evaluate, but likelihood will rise with the sustained warm temps forecast.
The deep mid-November crust appears to be waking up and several avalanches have recently released down 200 cm in the snowpack.  Conservative terrain selection is critical while the alpine snowpack is warmed for the first time this winter.
The lack of an overnight refreeze will make the impact of Saturday's 2200m freezing levels even stronger. Warming aside, new snow, wind, and rain are set to provide ample natural triggers for deep persistent slabs.
Be careful not to overestimate the stabilizing effect of cooling temperatures on Sunday. Rain has saturated the snowpack with warmth and deep persistent slabs still have the potential to release naturally or with a sufficient trigger on Sunday.

Facets overlying the Nov 6th crust are still producing whumpfs and settlements indicating that this layer is still possible for skiers to trigger.
The Nov crust is beginning to facet out in some areas but still use caution and evaluate this deep weakness.
Thin spots, heavily wind loaded features and steep rocky terrain are areas where the Nov6th will be a bigger problem. Dig down to assess the crust and its reactivity if in question.
This layer has been the main sliding layer over the past week.&nbsp; Expect any new slides to step down to this layer.
Storm slab avalanches may step down and trigger larger avalanches on weak layers deep in the snowpack.
Persistent slabs are most likely to be triggered from shallow snowpack areas, or with a very heavy load.

The Nov 6th crust should still be in the back of your mind. Recent avalanches on this layer combined with uncertain means of triggering make venturing out onto big open slopes a committing choice.
Large, deep slabs are occurring naturally and from human triggers. The recent snow has tipped the scale and all avalanche terrain should is suspect. Numerous avalanches have been triggered from long distances away. Avoid avalanche terrain!
The weak snowpack continues to dominate the entire region, and avalanches can be easily triggered in shallow areas at treeline and above. Keep your distance from avalanche starting zones, and work the terrain very carefully to manage your exposure.
The current avalanche cycle is overloading the entire snowpack and many deep avalanches have been observed sliding on the ground. Fracture lines in some areas greater than 150cm deep. The situation is very touchy; avoid all avalanche terrain.
The possibility of natural and skier triggered avalanches remains high. Stay out of avalanche terrain until things settle down. Look for protected skiing in the trees on moderate angled slopes with no exposure to alpine and tree line start zones.
Expect to see less natural activity concerning this layer, however, it is still ripe for human triggering. If triggered, expect large and destructive avalanches with fracture lines up to 200cm deep.
Full depth avalanches have been seen daily on this layer. We expect another natural avalanche cycle on this layer on sunny aspects with the forecasted warm temperatures and sun.
Full depth avalanches continue to be seen daily on this layer. We expect another natural avalanche cycle on this layer on sunny aspects with the forecasted temperatures and sun. Even a cornice release in the heat could trigger a large avalanche.
Watch for daytime warming and areas receiving large amounts of sun. avalanches may run full path and affect valley bottoms and trails crossing avalanche runouts.
Frequency of full depth avalanches on the basal depth hoar/crust is starting to slow down.  Any slope that hasn't avalanched should be treated with caution, as it will be very high consequence if you trigger this layer.

The weak and unpredictable snowpack persists in the Lake Louise area and eastern side of the forecast region, where all steep terrain remains suspect. This problem is much less prominent west of the Divide, where the snowpack is deeper and stronger.
Thin areas and steep terrain that has not  yet avalanched should be avoided. Thicker moderate angled terrain  with low consequences would be a good choice.
Low likelihood, high consequence. This means the chance of triggering is decreasing, however, if you do, it will be a big slide.
Thin areas will have the biggest potential for triggering the basal depth hoar/crust layer. Caution is advised in steep, planar features. Avalanches will be full depth with large consequences.
Triggering of the basal depth hoar/crust will be most likely from thin snowpack areas. These are harder to trigger now, but if you hit the &quot;sweet spot&quot;, the avalanche will be full depth and large consequence.
We have seen the basal facets wake up at lower elevations in the Kootenay area. This may not be widespread, but will cause large avalanches if initiated.
With the cooling temperatures this will become less reactive to skier traffic. Large triggers such as cornice drops or large slab releases could still cause failures on the basal facets.
In thinner snowpack areas, many avalanches are initiating as a storm or persistent slab and are stepping down to this layer.
The primary problem in the snowpack is the interface between the recent storm snow and the November 6th and 24th facet/crust interfaces. This is the problem responsible for the majority of the avalanches in the past week. Watch for remote triggers.

The March 13 90cm of snow has melded with the snowpack making for a deep persistent slab. North and South winds make it present on a variety of aspects overlying weak basal facets. Cornice failures can trigger this in a big way.

Triggering any of the above problems have potential to initiate this layer and create large full path avalanches.
This layer is proving very susceptible to human triggering as evidenced by the two remotely triggered slides today. Extensive whumphing and cracking experienced particularly at treeline elevations.
Warmer temperatures will contribute to overloading the weak basal facets leading to full depth avalanches in the valley bottoms. Be cautious of steep slopes along terrain traps such as creeks.
Depending on elevation, this layer is either bridged by a hard mid-pack at higher elevations and likely to be triggered from a shallow area. At the lower elevations there is minimal support in the snowpack and is easier to trigger.
Basal weakness means that the potential for full depth avalanches still exists.&nbsp; Smaller avalanches have the potential to trigger deeper instabilities.
The basal facet layer is of great concern as it is&nbsp; the most significant weakness in this year's snowpack.  Use extra caution in areas that have not previously avalanched, especially on open treeline slopes.
The basal facets are weaker below tree line as many whumphs noted. Where the snow is deeper at higher elevations, the mid-pack is bridging the weak basal facets; however, snowpack depth varies so much that its hard to inspire confidence in stability.

Odds are you will not be able to trigger this layer from fat areas in the snowpack. It exists at all elevations and aspects and the variability in the snow pack is so widespread it does not inspire confidence anywhere in the terrain.
Bridging above this layer makes it stubborn to initiate; however, it will be big when it goes. A sudden warming, large additional snowload, large triggers, or surface avalanches may tip the scale. Be aware of thin locations as likely trigger spots.

Under the additional load of ongoing snow large avalanches are expected from this layer.
Increased loading above this layer from the recent storm snow has produced number releases up to size 3. These are mostly from the alpine and treeline elevations and are running down to the valley bottoms.

March 3rd 45cm of new snow load produced size 3's. This activity has subsided. They were from the alpine and treeline elevations running to valley bottoms. One should consider it a concern if the persistent slab above is initiated and steps down.

Natural activity has subsided but don't let your guard down. It remains a major concern with a extremely weak base of depth hoar. Trigger spots would be shallow zones or a step down effect if upper layers are initiated.

With additional snow loading, rain  and warm temperatures this problem has become reactive producing full path releases 
Additional loading on a weak base is producing large natural avalanches.
The widespread observations of large and deep avalanches indicates strongly that many of these events are from this instability. Increased loading and warm temperatures will keep this layer active.

The lower snowpack is riddled with weaknesses particularly where the&nbsp; snow&nbsp; is shallow over rocky terrain.&nbsp; Today a&nbsp; large cornice failure triggered a size 3 slab on a NE treeline feature. Debris is running far into the valley bottom.
The lower snowpack is weak with a crust from November surrounded by loose facets and depth hoar. This weakness is most developed in shallow snow with rocky terrain. A cornice failure triggered a size 3 on a NE treeline feature near Parkers ridge.
Although this deeply buried crust, on which this weakness beds, is widespread we think that it will be at its most reactive on solar facing slopes. Thursdays weather is abnormally warm and its effect on the snowpack will be to destabilize it.
Solar triggering is possible on steep south facing slopes creating large full path avalanches.

Persistent slabs remain a problem. Areas exposed to large triggers such as cornices or smaller avalanches / sloughing from above are most likely to trigger this midpack weakness.

This weak layer of snow persists 30 to 40 cm above the ground. Triggering a wind slab could produce the large load necessary to wake this layer up. Use caution in thin areas particularly with steep, planar, or unsupported slopes.

In shallow snowpack areas there is a possibility that the deeper instabilities could be triggered. Our growing snowpack and milder temperatures are helping to reduce the chance that this layer could be triggered in most areas.

Snowpack depth is highly variable. It might be hard to spot the shallow areas where triggering this deeply buried weak snow is more likely. Large loads such as falling cornices or surface avalanches also have the potential to wake up these slabs
Be conservative with your terrain selection and consider steep or unsupported planar slopes carefully. Assess the snowpack often: the variable nature of the snowpack makes it hard to avoid shallow areas where triggering may be more likely.
Be conservative with your terrain selection and assess steep or unsupported planar slopes carefully. The new snow may be hiding shallow areas where triggering may be more likely and with the variability in snowpack there are many thin areas.
Be conservative with your terrain selection and assess steep or unsupported planer slopes carefully where the snowpack may be thin. In these areas it may be possible to trigger the weak faceted area created early in the winter.
30 cm above the ground, this weak snow is a serious concern. Travelers should carefully consider snowpack depth, terrain shape, and slope angle. Use your probe to confirm depths when you are uncertain.

This weak snow under the entire snowpack remains a concern especially in thin areas. As warming and loading occurs, avalanches described in the problems above could provide a large load triggering larger events on this layer.
With widespread avalanches occurring the potential for the weak snow at the bottom of the snowpack to be triggered as a large avalanche is elevated. Give big terrain a wide berth until things have a chance to settle.
The slab of well settled snow that protects the weak snow at the base of snowpack is not very thick in many areas. As the storms continue to place stress on the snowpack, and with significant surface avalanches expected, larger events could occur.
Do not forget that there is weak snow under the entire snowpack. In shallow areas this faceted snow has continued to weaken and the slab above it that is holding the snowpack together has become stressed by recent loading.

The chance of triggering the deep weak layers from early February are diminishing but these layers have not completely disappeared. Any slope that have not slid should be suspect for possible large destructive avalanches.
Weak faceted layers from previous cold temps in the mid and lower snowpack remain a concern, particularly in shallow snowpack areas where facetting is more pronounced and triggering is more likely.
Deeply buried Persistent weak layers from a cold winter have produced few results in recent testing, but are now being heavily loaded. In sheltered/windward terrain, this is the first large load on these layers. Avoid previously shallow areas.

Several large avalanches have been observed from previously shallow terrain, where storm snow fell on large facets.  Observations have been limited; it is possible that Persistent slabs may be triggered in deeper areas also.

Several large avalanches have been observed in the front ranges and/or windward terrain, where storm snow fell on shallow facets over ground. Rain on Thursday triggered an avalanche on the basal facets, in a shallow snowpack area Below Treeline.

The first sustained warming event of the season will put the deeply buried December Facet layer to the test. The 'where' and 'when' of this problem is difficult to evaluate, but likelihood will rise with the sustained warm temps forecast.
