Recent snowfall amounts vary depending on location. Reports from Shangri-La indicate as much as 10cm of new snow.  This new snow  is forming wind slabs that are sitting on the previous widespread hardslab and may be sensitive to light triggers.
The hard windslabs that dominate the alpine snowpack have been unreactive lately. It still may be possible to trigger an avalanche on steep unsupported terrain from thin areas and edges of these slabs.
Solar aspects are going get hit hard by the sun today. Natural avalanches are expected, particularly on steep slopes and around exposed rocks. It will also make skier triggering of the storm slab more likely. They may step down to a crust below.
Steady SW winds continue to transport snow and trigger natural avalanches from steep lee slopes. Isolated pockets of wind slab will have formed immediately below ridgecrests; most likely in serious terrain where a ride would have severe consequences.

Wind and little new snow dominate the alpine landscape. On certain lee features this crust is thick enough to form a wind slab,  and it may be possible to trigger an avalanche on steep unsupported terrain from thin snowpack areas.
The snowpack in the alpine and at tree line consists of multiple wind laminated layers.  How the terrain has influenced the formation and character of these layers on a given slope is the main question to keep in mind while traveling.   
A touchy surface hoar layer is down 25-40cm. There have been human triggered avalanches on this layer daily. Avalanches are increasingly possible with new snow and rising winds today adding load, and mild temperatures making the slab more cohesive.

Recent low density snow has buried surface wind slabs. Although they are hard to trigger at the moment, they are hidden. Keep this in mind when exploring steeper alpine features. Also, ski conditions in the alpine today resembled dust on 'sastrugie'.
New slabs forming in exposed areas with SW winds. These are spotty and small right now but will grow in size and thickness with time. Monitor the texture of the snow as you move into open areas and avoid steep terrain where these slabs are present.
Sluffing occurs easily given terrain over 40 degrees. This will diminish as the storm snow settles and is likely to occur only on  shaded slopes following the solar heating on Feb 18. Manage your sluff and your group carefully.

The forecasted incoming warm snowfall may bond well to the current windslab layers at the snow surface. However, if there is significant snowfall and high winds, yet another slab will develop.
Soft and hard windslabs 10-60 cm thick exist in the lees of features.  Fresh slabs will form with the incoming storm and will likely be touchy.  This may overload existing wind slabs.  A natural avalanche cycle is likely over the next few days.
With additional precipitation, warm temperatures, and moderate to strong SW winds we expect new wind slabs to form and the hazard to rise over the next couple of days.  We may also see increased cornice failures with the warm temperatures.
Rapid loading by snow and wind is overloading the snowpack. Expect widespread natural avalanche activity, with large avalanches running into valley bottoms. Avalanches may step down to deeper persistent weak layers.
The warm, mild conditions with additional precipitation have increased the likelyhood of cornices failures and wind slab avalanches. These should start to stabilize with cooler temperatures on Sunday but should still be treated with caution.
Developing slabs overlie existing hard windslabs.  Visibility is poor, but we expect naturals to be occurring involving these layers.  In thinner snowpack areas, avalanches may scrub to ground, incorporate the weak snow and run further than expected.
  With the added load, cornices may fail and trigger slopes below.  Be mindful of over head corniced features.

More than 80 cm of new snow has fallen in the Icefields area since Wednesday.  This snow is settling to form soft slab conditions on sheltered alpine and treeline slopes.
Last weeks warm and wet storm rapidly deposited 50-60cm of heavy, moist snow at treeline. This was deposited on low density snow sitting on a crust and or surface hoar and is bonding poorly. At lower elevations, rain saturated the upper snow.
It will likely take a large trigger, like a cornice fall or another avalanche to trigger the surface hoar/crust layer from February down 1-1.5m. If triggered, however, the resulting avalanche would be very large and destructive.

Easterly wind (reverse from the usual) and light snow fall amounts will load 'low snow' areas and create a condition for dry loose snow avalanches. This is mostly a concern for riders and climbers in gully/couloir features in the alpine.
40-50cm of storm snow is being transported by variable winds. N'ly winds have reverse loaded solar aspects and may bond poorly where buried sun crusts exist. The wind is also building large, unsupported cornices.
Loose snow sluffs can gain mass in steeper terrain catching a rider off guard today. Be mindful of terrain traps (e.g. gullies, cliffs) where small avalanches can be more serious.
Infrequent large avalanches have occurred on deeper instabilities. Shallow, rocky areas where the snowpack is thin and weak are most likely where they will be triggered.
Windslabs can be found on lee aspects in exposed terrain around ridgecrests. Where these slabs sit on previous crusts, the likelihood of a skier triggered avalanche increases.

The crust and or depth hoar at the base of the snowpack means that any avalanche that begins will likely step down and involve the entire snowpack.
Wind transport has created a mix of hard and soft slabs on all lee and cross loaded slopes . Terrain choices are tricky because the only places that have enough snow are wind loaded. Use shallow slope angles to minimize risk.
Currently there is a variably distributed persistent slab in a generally shallow snowpack. Although stubborn, if this slab is triggered it will result in a full depth avalanche running on weak layers at or near the bottom of the snowpack.

Winds associated with the recent snowfall have been strong enough to create slabs in the alpine and exposed areas at and below tree-line. These slabs are concealed by the incremental snowfall of the last few days.
The presence of a deep surface-hoar weakness remains a concern for backcountry travelers. It will likely take a large load to trigger it, like a cornice or someone who ate too many perogies over Christmas.
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.
Watch for areas of wind loading. If a wind slab is triggered it may step down to deeper layers.
  A shallow spot in the snowpack could trigger a windslab which in turn would step down and release the entire snowpack.
Lee aspects have an upper snowpack consisting of several hard windslabs which could release and affect the layers below it.
Storm slabs will become an issue at the peak of the incoming system. Strong winds and warm temp's accompanying the new snow will develop slabs quickly in exposed lee features at all elevations.
Wind slabs are still reactive to rider triggering in the upper snowpack. Large planar or unsupported slopes should be treated with respect.
A deep persistent weakness lingers, down roughly 120cm. It will take a large trigger to initiate this layer, but if it starts to move, propagation would likely be wide and deep, creating a larger avalanche.
Triggering this layer from a shallow area is possible and would have high consequences in terrain features of any size.
Multiple wind slab layers at the top of the snowpack can be triggered and may step down to the deeper instability at the bottom of the snow pack.
Hard surface slabs are found near ridge crests and in gully features. These are highly variable at the moment with suspect pockets in steep and unsupported terrain.
Weak faceted or sugary snow can be found almost everywhere 30 to 40 cm above the ground. Triggering in thin snowpack areas remains a concern. Some natural avalanche activity should be expected if snowfall amounts are significant Friday.
The incoming snow will cover a variety of firm surfaces including the windslabs described above, wind affected surfaces, and sun crusts on S aspects. West winds and mild temperatures are likely to encourage slab formation in specific areas.
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.
Watch for areas of wind loading or open slopes with wind effect. If a wind slab is triggered it may step down to deeper layers.
Storm slabs have formed at all elevations, likely up to a metre thick in alpine and tree-line lee areas. It will take a bit of time for these to settle into the snowpack.
Older wind slabs buried on various weak layers linger below all the new snow. These slabs have the potential to fail with the new, heavy load.
The heavy trigger may have arrived with this latest dump. Large avalanches are occurring, and may be stepping-down to this deeper layer.
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.
Watch for areas of wind loading or open areas with wind effect. If a wind slab is triggered it may step down to the weak basal layers. The new snow will be hiding these wind slabs in many areas.
The 20-30 cm of new snow can be expected to slough with any wind that occurs over the next 24 hours. Ice climbers should especially watch for sloughing in steep gully features and terrain traps.

Wind slab layers at the top of the snowpack can be triggered and may step down to the deeper instability at the bottom of the snow pack.
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.
New wind slabs are forming with lots of new snow available for transport.  If triggered these have the potential to step down to deeper facet layers and create large avalanches.  Probe for new or old wind slabs and avoid steep lee loaded terrain.

Recent storm snow and strong winds in the alpine are forming new windslabs at upper elevations.
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!
Windslabs have formed over the last 48-hours, and this trend will continue over the next few days as strong north winds are forecast at higher elevations. Small avalanches are likely to step down and release larger avalanches on the deep layers.
Temperatures are warmer up high today due to an inversion. Caution on and under steep solar aspects when the sun is shining on them. Loose avalanches will most likely originate from cliffs.
Wind slabs at ridge crests and in the alpine from the strong winds during the last storm may still catch a rider off guard.
Storm snow instabilities still exist in the recent storm snow. Although it appears to be bonding well, another day or two of settlement and observations is needed before it is no longer considered to be a problem.

Recent winds have created thin windslabs on steep, windloaded terrain features. Approach all windloaded terrain with respect, stop at the top and evaluate before you choose your route through.
Be cautious on the lee of ridge crests or on cross loaded terrain where previous wind slabs may still linger.
Snowpack tests yesterday showed instabilities in the upper 60cm in the moderate range.
Strong West winds made quick work of the 40 cm of snow that fell before the weekend. Thin, spotty wind slabs found behind exposed features well below treeline can be easily triggered by skiers. Expect these slabs to be more significant TL and above.
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.

Snowpack tests continue to show sudden planar results deeper in the snowpack (down 120cm). Caution is still needed when traveling into lee or cross-loaded features.
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.
The upper snowpack is a stratified layer of multiple windslabs. Recent field tests have produced failures with moderate shear strength. Currently this condition is less prevalent at treeline. Forecasted snowfall and wind will increase this concern.
The weak base is the real danger. Moderately angled slopes with thicker snowpack are the best choices for not triggering this layer.

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.
A new storm slab is developing. The new snow is still loose and unconsolidated, but with mild temps and continued loading by new snow it will become more of a concern. Heads up if the snow starts to feel slabby. Watch for sluffing on steep slopes. 
With lots of loose snow available to be transported, and sustained moderate winds above treeline, new windslabs are forming. In addition, cornices are becoming large and may fail triggering the slopes below.
The persistent weak layers are now fairly deep in the snowpack. They will&nbsp; likely need a sizeable trigger, like an avalanche or a large chunk of cornice falling. They may be triggered from thin snowpack areas by a lighter trigger, like you.
New snow will likely overload deep weaknesses in the snowpack causing increased avalanche activity.
Alpine and tree line winds had added a stiff wind slab to the weak snowpack. If this layer triggers it will likely step down to the basal weakness mentioned above.
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.
Wind slabs will build quickly over the weekend. Expect sluffing in steep alpine terrain and avoid steep lee loaded features. Triggering a wind slab may also cause it to step down to the basal facets resulting in a larger than expected avalanche.
60 to 70cm of storm snow has fallen over the past 3 days with strong southerly winds. Heavy density snowfall is rapidly loading a previous layer of low density snow causing storm slab formation.

The November surface hoar layer can still be triggered by large triggers such as avalanches or cornice fall. There have been reports of backcountry operations seeing avalanches failing on this layer in the region.
Open terrain near ridge crests are likely spots to find recent wind slabs. Use your poles and probe to help detect signs of instability.
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.

Unlike the deep persistent slab problem, the storm slabs will eventually start to bond to underlying surfaces over the coming days.
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.
As the warmer temperatures stiffen up the snow surface, even a small avalanche could step down to the basal facet layer resulting in a full depth avalanche.

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.
These old, hard slabs still deserve respect especially in steep or unsupported terrain. Remember that triggering these surface slabs may create enough load to pull out a larger deep persistent slab. Triggering may be easier in warmer periods.
With mild temperatures and strong solar radiation any snow near rocks could easily release. The large load created by a falling cornice could trigger the deep persistent slab.
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.

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.
This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain.
Strong northerly winds have redistributed snow into isolated pockets of wind slab at alpine elevations.
Winds have redistributed some of the new snow creating a soft slab that was seen to react to rider triggering. Watch for this are on steep convex rolls with a buried sun crust. Shooting cracks from your ski tips is an indicator of this instability.

This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain.
Strong northerly winds have redistributed snow into isolated pockets of wind slab at alpine elevations.
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 recent snow has created thin wind slabs in the alpine and at treeline which could be a problem in steep confined terrain such as gullys and couloirs.
Expect to see some wind loading on south and west aspects, not typical of this area. The new snow has not bonded well to the old surfaces and was reactive early this week to rider traffic. People could expect the same but with a stiffer windslab.
This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain or by a large load.
Strong northerly winds from a few days ago redistributed snow into isolated pockets of wind slab at alpine elevations.
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.
Expect to see some thin slabs on S and W aspects in the alpine and exposed tree-line elevations, due to cold Arctic winds blowing from the N and E. These slabs will be stiffer with the cold weather, and have not bonded well to the older surfaces.
This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain or by a large load.
Strong northerly winds from a few days ago redistributed snow into isolated pockets of wind slab at alpine elevations.
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.
Riders are still able to ski-cut thin (5-10cm), hard slabs in lee features. With the reverse loading of N and E winds, slabs can be found on all aspects. While the slabs are likely too thin to bury a person, they could push one over steep terrain.
This layer is bridged by a strong midpack. Keep in mind that shallow locations could produce a failure in this layer which would step down into the facets and slide full depth.
The 40 cm of snow sitting on the ground continues to loose strength. The mid-pack that is holding everything together varies greatly in depth. Use your probe to verify that you are traveling in fat areas and use extra caution if you are not.
Variable wind directions over the last few days have created thin and soft slabs in a wide range of open areas. Surface snow is faceted which is  discouraging slab formation. These slabs sit on weak snow over firms surfaces: keep them in mind.
Thin wind slabs exist in exposed tree-line and alpine lee features on all aspects. It is possible for riders to trigger isolated pockets.
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.
This layer may become reactive if there is a sudden temperature warming through the day.&nbsp;
Thin pockets of wind slab are present on exposed treeline and alpine lee features. North and east winds have created reverse loading conditions.
This layer may become reactive if there is a sudden temperature warming through the day.
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.
Thin pockets of wind slab are present on exposed treeline and alpine lee features.&nbsp; North and east winds have created reverse loading conditions.
This layer may become reactive if there is a sudden temperature warming through the day.&nbsp;
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.
Isolated pockets of windslab to watch out for in exposed areas. Winds were predominantly from the East and the North until yesterday morning, loading south and west slopes near ridge tops.
This layer may increase its reactivity if there is a sudden temperature warming through the day.
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.
Any new snow or wind slabs will be sitting on a mix of facets, surface hoar and sun crust. This has potential to create a good sliding layer. Watch for sluffing in steep terrain starting Tuesday, and deeper storm slabs failures by Wednesday.
As new snow falls and is redistributed by W winds, expect slabs to form quickly or to&nbsp; contribute to soft windslabs that already exist&nbsp; at Treeline and above. In recent days even very soft slabs have failed easily over weak, faceted surface layers.
In terrain over 40 degrees skiers may easily sluff the Surface Snow which will continue to gouge out a trough until it hits lower angled terrain. These events occur naturally in very steep terrain. Expect this to get worse with more snow.
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.
35cm of new snow has fallen onto a surface that will not bond easily. Triggering avalanches will not be difficult due to the nature of the recently buried weak layers.
Winds have picked up with lots of light snow available to be pushed around. Expect wind slabs to continue to form at higher elevations as the day progresses.
This layer may increase its reactivity if there is a sudden temperature warming through the day.
Soft slabs are forming rapidly with the new snow over a very weak and widespread layer. These slabs can be triggered from a distance on steep slopes and require very conservative terrain selection and route finding.
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.
By Wednesday there may be up to 25 cm of new snow being blown into fresh windslabs. Fresh slabs like this are touchy, and in places their depth may exceed 50 cm. Be very careful in all windloaded areas, and looks for clues and cracking under foot.
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.
50-60cm of storm snow overlies an old surface that will not bond well. Temperatures have increased and winds have picked up, creating stiffer slabs that are ripe to fail.
Winds have picked up from the W/SW and there is 50-60cm of new snow available for transport. Expect wind slabs to continue forming in lee areas at all elevations.
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.
15cm of new snow with variable wind directions and speeds have translated to wind loaded pockets of storm slab potentially 45cm thick overlying weak surface facets. More snow Thurs-Fri will add to this condition. Loose avalanches are also possible.
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 10-20 cm of new snow has created touchy windslabs up to 30 cm thick with impressive propagations for their small size.
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 storm slab overlies a weak surface and is not bonding well. Many avalanches have already slid on this interface, but if a slope has not released, it should be considered a ticking time-bomb.
Wind slabs continue to develop in lee features at alpine and tree-line elevations. There is plenty of new snow to feed the wind slab development, so if winds pick up in the area you are skiing, expect the danger level to bump up a notch.
New snow with variable wind directions and speeds have translated to wind loaded pockets of storm slab potentially overlying weak surface facets. Loose avalanches are also possible.
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.
Winds will be forming slabs in the lee of ridge crests and exposed areas. These will be likely lying over facets or hard surfaces.
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.
Wind and warm temperatures have created higher density snow over the weak faceted crystals in almost any open areas. Very easy triggering means that skiers should treat all significant slopes with respect. SE to SW slopes seem extra touchy
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.
The storm slab is just getting thicker and heavier on the underlying weak interface. Any large, open slope that has not slid should be treated with caution, as it awaits just that extra amount of load from a person.
Strong winds in the alpine have redistributed the copious amounts of new snow into very touchy wind slabs. Expect to find extensive cracking and whumphing under your boards where the wind has affected the surface.
Pockets of wind loaded slab overly weak surface facets in sheltered areas at tree line and above.
Winds will continue to build slabs in the lee of ridge crests and exposed areas.  These slabs rest on facets or hard surfaces and have not bonded to these layers yet.
Based on current wind patterns from our remote weather stations, and available new snow for transport, wind-slabs will still be lurking in the alpine, approximately 20-60cm thick.
Some pockets of wind slab exist in sheltered alpine features at ridge line. No natural activity was observed today but with more snow and strong SW winds we expect the hazard to increase through Saturday night and Sunday.
These recently formed slabs have proven to be very easy to trigger failing naturally and with light loads. Limit your exposure to significant slopes. Do not get taken by surprise by the long propagations that are occurring.
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.
A 100 cm storm slab sits on a weak layer.&nbsp; Skiers and riders will likely trigger this layer in avalanche terrain.&nbsp; Remote triggering is a concern, watch out for adjacent slopes.
Exposed terrain will have wind deposited snow forming slabs.&nbsp; Moderate to strong winds this AM are rapidly loading avalanche start zones.
New windslabs are forming and adding to the load on lee aspects, primarily East facing terrain. Small windslabs may trigger deeper persistent slabs and increase the consequence of involvement.
Mod/strong wind today has developed this layer further. Expect it to be most reactive in the alpine on all aspects. In places, these wind slabs could be 60cm thick.
These recently formed slabs have proven to be very easy to trigger failing naturally and with light loads. Limit your exposure to significant slopes. Do not get taken by surprise by the long propagations that are occurring.
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.
20cm of additional load overnight totalling 1.2m over a weak layer which has been very reactive this past week. Riders have reported cracking, whoomphing and avalanches on this layer. This is in addition to any shallower storm snow instabilities.
Winds from the current weather pattern have been steadily in the moderate to strong range. Expect to see more slabby conditions at higher elevations reactive to human triggering.

The interface between rapidly settling storm snow and the previous surface is characterized by crust and facets and new slabs are touchy in specific terrain - particularly steep, lee aspects below ridge crests.
Recent Southwest winds have created new windslabs.  Caution is warranted with crossloaded gully features.
The recent storm snow is settling and bonding to itself. There is still a poor bond at the storm snow interface (facets and surface hoar) down about 30-40 cm.
Continued south west winds have created fresh wind slabs in lee alpine terrain. These wind slabs are reactive to skier triggering.
As the slab over the weak layers down 100-140cm becomes more cohesive, it changes in how it reacts to a riders weight. The highly reactive stage may have passed but it is at a depth where triggering will be less frequent but much more dangerous.
We had strong winds yesterday morning and there's a concern the associated instabilities still exist up high.
The interface between rapidly settling storm snow and the previous surface is characterized by crusts. facets and surface hoar. New slabs are touchy in specific terrain - particularly steep, lee aspects at treeline and sub alpine elevations.
Recent southerly winds have created new windslabs. Caution is warranted with lee and crossloaded features.
The storm snow is starting to settle into a cohesive slab. As the slab stiffens, the weak layer will get harder to trigger, but the consequences will be greater. The nature and distribution of the weak layer means it will be with us for a while.
Recent SW winds are creating touchy windslabs in lee ALP and TL terrain. If triggered, these windslabs will step down to the Feb. 10th layer.
As the slab over the weak layers down 100-140cm becomes more cohesive, it changes in how it reacts to a riders weight. The highly reactive stage may have passed, but it is at a depth where triggering is less frequent but much more dangerous.
Strong winds overnight from the S-SW will have created surface wind slabs in the alpine and tree-line.
The cornices have undergone tremendous growth in the past week with all the new snow and winds. These cornices could be the large load to trigger the thick slabs overlying the Feb 10th interface. Expect large avalanches if caused by cornice-fall!
The persistent slab interface is a combination of crusts, facets, and surface hoar overlying a solid midpack bridging weak basal facets. It will be large if triggered. Caution on steep lee treeline and subalpine aspects with variable snow depths.
Caution on East aspects above treeline especially at ridgecrest transitions. Field patrol in Maligne area triggered size 2 of this nature where wind has firmed the recent storm snow into a windslab overlying previous layer of facets and surface hoar.
The recent storm snow is settling but a poor bond still exists on the storm snow interface. Natural activity has decreased but it is still possible for skiers to trigger this layer.
Recent SW winds have created touchy wind slabs on lee alpine and treeline terrain. These wind slabs are reactive to skier triggering.
The storm slab, which is 100-140cm thick and overlies a weak interface, is becoming more cohesive. However, the bond to the underlying interface is not showing much improvement. Skier triggering of this layer will have high consequence.
Fresh wind slabs from the previous couple days are evident in open alpine and tree-line elevations. Cracking and whumphing indicate that you have found them!
The large cornices adorning ridge-tops are the large, natural trigger that could initiate a very large avalanche. They are obvious overhead hazards to be avoided for the next long while.
This persistent weak layer consists of facets and surface hoar that were covered. It sits on a mixture of crusts and firm supportive snow. This seems to be of most concern at the Treeline and lower alpine elevations between 2000m and 2400m.
Lee aspects of ridgetops and terrain features should be carefully evaluated for windslabs.
A poor bond still exists between the storm snow and the Feb 10 interface. This interface is reactive to skier triggering. (see avalanche details)
Continued SW winds have created fresh wind slabs in the alpine
These recently formed slabs have proven to be very easy to trigger failing naturally and with light loads. Limit your exposure to significant slopes. Do not get taken by surprise by the long propagations or remote triggering that has been seen.
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 to the point of failure.
This problem is becoming increasingly challenging. The clues of instability, like cracking and whumphing are tapering off, but tests and continued avalanches indicate that this thick slab is triggerable and will produce very large avalanches.
Winds during the last week have transported the new snow, loading lee slopes and forming cohesive wind slabs. In areas where the snow is more cohesive, triggering of these slabs is likely. If triggered these slabs will likely step down deeper.
Yesterday, a slab 1-1.5 meters deep was observed that was triggered by cornice failure. Large cornices exist along ridges, and are may fail with fluctuating temperatures and sunny periods. These are big triggers that could initiate BIG avalanches.&nbsp;
This persistent weak layer consists of facets and decomposing surface hoar under 30cm of surface snow. It sits on a mixture of crusts and firm snow. It is of most concern at treeline and subalpine zones between 2000-2400m.
Where ever the wind has buffed the surface into a slab should be carefully evaluated particularly ridgetop transitions. Pockets of slab have also been created by valley bottom winds and have been found in exposed locations at treeline and below.
There is still a poor bond between the storm snow and the Feb.10 layer of facets and surface hoar. This interface is still very susceptible to human triggering.
Wind slabs have been forming at higher elevations from SW winds over the last few days.
A strong slab overlies a very weak layer buried down 1-1.5m. The snowpack now demands your respect, if you trigger this layer a large, high consequence avalanche will result.&nbsp; Use caution in shallow snowpacks, where triggering is more likely.
Use caution as you transition into exposed terrain.&nbsp; Triggerable wind slabs may be present on lee features.&nbsp; If triggered these slabs may step down to trigger deeper instabilities.
Yesterday, a slab 1-1.5 meters deep was observed that was triggered by cornice failure. Large cornices exist along ridges, and may fail with fluctuating temperatures and sunny periods. These are heavy triggers that could initiate BIG avalanches.
The persistent slab overlies 2 main weaknesses that will not go away anytime soon. A decomposing surface hoar-surface facet layer 30cm down and thick layer of basal facets-depth hoar. Its spatial variability makes it difficult to predict.
Carefully evaluate ridgetop transitions where winds have buffed the surface into a slab. It rests on the suspect surface hoar-surface facet layer 30cm down. Valley bottom winds have created slab pockets in exposed locations below treeline.
The storm snow interface down 40-70 cm still producing easy to moderate results. Natural cycle is over but still possible for skiers to trigger this layer.
Recent winds have produced wind slabs in lee alpine terrain. These wind slabs could step down to the storm snow interface resulting in large avalanches.

&nbsp; These slabs have become a little less touchy but are now buried by an additional load (60cm over the past week). Limit your exposure to significant slopes. Do not get taken by surprise. Long propagations are still likely.
&nbsp; 60cm of new snow over the past week with transport tapering off the past 5 days. Loose dry concerns could step down to the weak faceted layer.
The natural cycle is over but the Feb 10th interface down 25-60 cm is still producing easy to moderate results, with lots of whumphing and some recent skier triggered avalanches. Stick to moderate angled, well supported terrain until things improve.
Recent winds have left isolated wind slabs in lee alpine terrain. If triggered these wind slabs could step down to the Feb 10th storm snow interface resulting in large avalanches.

Sunshine and the warmer alpine temperatures may cause them to break. Shaded slopes may have cornices in the sun well above you. This hazard is the type of load that can trigger the buried weak layers.
Snowpack tests on this layer today produced easy results. Despite the easy results no avalanche activity was noted. This is a layer to approach cautiously over the next few days.
This layer is becoming less reactive. However, be observant of lee areas and how the layer may react at a local level.
Evaluate ridge top transitions where winds have buffed the surface into a slab. It rests on this suspect layer 30cm to 45cm down.
The strong mid-pack is bridging the layer well through the forecast area. Its spatial variability over the terrain does make it difficult to predict and snowpack tests show it to be very weak. Be careful in shallow start zones.
The 1-1.5m slab over the weak layers continues to settle and become more cohesive. This problem will take a while to heal and requires good terrain management. Be wary of open, unsupported slopes and convex rolls, particularly at tree-line and below.
The large cornices adorning the ridge-crests will see lots of sunshine and warming today, potentially destabilizing them and causing them to fall. The mass of these &quot;freight-trains&quot; smacking the slope could be the trigger to start a very large slide.
The Feb.10 interface of weaker crystals is slow to gain strength. Slab properties above this layer are becoming stiffer, and human triggering is very possible. These seem to be the most touchy on solar aspects where there is a buried suncrust.
These are becoming less reactive, but look for wind slabs in lees of alpine features and exposed areas.
At higher elevations wind slabs will be more abundant and thicker, similarly in cross winded valleys existing glacial terrain. The Feb 10th weakness has recently been found down 20-70cm between 2,200m-2,400m, but is hard to trigger.
We have seen very few avalanches from this layer in the past 2 weeks. A strong midpack , when present, prevents triggering from all but the largest loads. Where the snowpack is shallow triggering will be considerably easier.
The 1-1.5m slab overlying the Feb 10th weak layer is slowly bonding to this interface, but is still reactive in tests. This problem requires good terrain management, such as avoiding large convexities and sticking to supported features.
Cornices are a definite concern, given their size and mass. If they were to fail, they could be the big trigger to initiate an avalanche in the deeper layers.
Carefully evaluate ridge top transitions and start zones where the winds have pressed the surface into a slab. This slab rests above a persistent facet layer 30cm to 45cm down.
The strong mid-pack is bridging the layer well through the forecast area. Its spatial variability over the terrain does make it difficult to predict and snowpack tests show it to be very weak. Be careful in shallow start zones.
Now 80 to 130 cm thick, these slabs threaten serious consequence. While the potential for triggering has dropped, do not get taken by surprise: long propagations and remote triggering may still be possible. Limit your exposure to significant slopes.
Westerly winds picked up at ridge top on Tuesday building wind slabs in the Alpine. There is a lot of snow that remains available for transport: North and East winds forecast over the next few days may create slabs in unusual locations.
A weak, persistent layer is buried under a thick slab. This layer is becoming more difficult to trigger, but if triggered will propagate widely producing a very large avalanche. Choosing appropriate terrain is key in managing this problem.
Cornices may be destabilized by fluctuating temperatures. If they fail, they could be the big trigger to initiate an avalanche in the deeper layers.
Moderate north winds have begun to load and stiffen up the surface slabs in open areas. This slab rests above a persistent facet layer 30cm to 45cm down.
The strong mid-pack is bridging the layer well through the forecast area. Its spatial variability over the terrain does make it difficult to predict and snowpack tests show it to be very weak. Be careful in shallow start zones.
The Feb 10th layer continues to produce sudden collapse test results in many areas. The cold temperatures will tighten things up a little and begin to weaken the slab over this layer but it is still a concern in many of the areas in the park.
As this weak layer, buried down around 1 m, gains strength human triggered avalanches are still possible. Areas of concern are open, unsupported slopes, convex terrain and thin snowpack areas.
Cornices may destabilize by fluctuating temperatures.  If they fail, they could be the big trigger to initiate an avalanche in the deeper layers.

The Feb. 10th layer is still a prominent feature in the snowpack producing variable results. We are seeing less activity over the past few days, but is still a concern in many regions of the forecast area.
Recent winds combined with cold temperatures have created widespread 10-20cm thick wind slabs up to pencil stiffness. These will be smaller in size and wont be a problem for a long time, but are a concern in steeper unsupported terrain.
As this weak layer, buried down around 1 m, gains strength human triggered avalanches are still possible. Areas of concern are open, unsupported slopes, convex terrain and thin snowpack areas.
Strong winds, including reverse loading from northerly winds have created pockets of wind slab. Feel for these deposits of firm, wind packed snow that will be getting buried by new snow today.
New snow is expected to come in steadily with south winds and may slowly overload this interface. Watch for a reverse loading pattern from the south to north aspects because of the shift in wind direction.
This layer is slowly gaining strength however test results continue to show that wide propagations are possible in some areas which would lead to severe consequences. Sudden collapse results and low scores in propagation saw tests are still common.
Yesterdays North winds created thin windslabs in many locations which are now covered with new snow. The increasing W winds will also build new winds slabs over the next two days. Probe for these with your poles and avoid steep wind loaded slopes.
Soft slabs can be expected at higher elevations which is sitting over a weak layers of sun crust and facets. As winds and snow amounts increase this slab will tighten up and become more reactive.
The sun crust/surface hoar layer down 1-1.5m is still producing hard sudden results in snowpack tests. This indicates that the layer is difficult to trigger but will propagate widely if it does.
These slabs became less sensitive with cold temperatures and increasing depth. Now as conditions change with rapid loading and warming, limit your exposure to significant slopes. Do not get taken by surprise. Long propagations may still be possible.
Variable winds have been actively creating windslabs over the last week. Now with more snow and moderate to strong SW winds in the forecast, expect to encounter slabs as you enter open terrain.
This layer is slowly gaining strength however test results continue to show that wide propagations are possible in some areas which would lead to severe consequences. Sudden collapse results and low scores in propagation saw tests are still common.
The new snow and moderate SW winds are staring to build soft slabs in lee areas above tree line. Probe for these with your poles and avoid steep wind loaded slopes. Sluffing out of steep terrain is also expected as more new snow arrives.
Steady snowfall and light to moderate winds may produce new windslabs in exposed areas.
Soft slabs exist at higher elevations. They sit atop a variety of surfaces (suncrust, facets, wind slab), and have been touchy to human-triggering. As more snow falls and the temp's warm up, expect them to become cohesive and more reactive.
The suncrust/surface hoar layer down 1-1.4m is still producing hard, sudden results in snowpack tests. This indicates it is stubborn to trigger, but if initiated, it will propagate widely, producing large avalanches.
New low density storm snow is shedding from steep terrain in the alpine and may have enough mass to ruin your day.  Expect sluffing on steeper slopes at all elevations.
Although winds are expected to remain relatively light, there have been several wind events in the past 48 hours with shifting gusty winds in the moderate to strong range that may have produced new windslabs at upper elevations.
This layer is gaining strength but tests and whumphing still show there is potential for wide propagation in some areas.&nbsp; Any avalanche on this layer could lead to severe consequences.
Soft to hard windslabs, generally 30 cm thick, can be triggered in lee terrain.&nbsp; In steep terrain, the snow is gaining cohesion to act like a storm slab. The new snow sits on a low density cold layer of snow that will take several days to bond.
Several loose snow avalanches were observed pouring over cliffs today to size 1.5.&nbsp; Winds will continue to be gusty for the next 2 days. Pay attention to terrain over head.
Field teams found touchy soft slabs in open alpine and tree-line lee features yesterday. These slabs appeared to be failing within the new snow, but some were popping very easily off the suncrust on solar aspects.
Lingering deep (1-1.4m) in the snowpack, the surface hoar/facet/crust sandwich continues to produce hard, sudden results in tests. If a large enough trigger gets this layer to fail, avalanches will be very large.
Steep alpine faces are sluffing regularly as new snow accumulates.
This avalanche problem remains a concern and may become more sensitive to triggering as temperatures rise and penetrate into the snowpack.
Lots of fresh snow and moderate southerly winds have created touchy wind slabs 40-60 cm deep in the alpine.
Test results on the Feb 10 layer generally in the moderate range but still show lots of potential for good propagation if triggered. Recent storm snow may be enough to activate this layer (see avalanche details). Lots of uncertainly with this layer
A touchy slab lurks on the slopes, and were easily triggered by field teams and artillery control at all elevations. As it becomes more cohesive from snow-load and warming temp's, we expect this slab to propagate easily.
The facet/crust &quot;sandwich&quot; is buried 120-150cm below the surface now. It is still producing hard, sudden results in tests, indicating that it can will propagate if a large enough trigger hits it. Avalanches digging into this layer will be large!
Little wind has accompanied the new snow of the past two days. Sluffing out of steep terrain may be of concern, particularly for ice climbers.
This problem has yet to materialize in full force, but with rising temperatures and forecast winds we expect this surface condition to become quite touchy over the weekend.&nbsp;
Test results on the Feb10 layer mainly in the moderate range with potential for wide propagations if triggered. The recent snow has been shown to overload this layer in the Kootenay,Sunshine, Yoho areas, and less so in the Louise region and Hwy. 93N.
Lots of recent snow and moderate westerly winds have created touchy wind slabs 40-60cm thick in many wind exposed areas.
Up to 55cm of new snow has arrived over the last week. Warm temperatures are helping it settle but it is siting on a variety of sun crust, old windslab or facets. Warm temps on Sun could provide a trigger for this layer.
Moderate to strong westerly winds have been building windslabs on lee slopes below ridge crests in the alpine and at treeline. These will continue to build over the next few days. Expect to encounter slabs as you enter open terrain.
These slabs became less sensitive with the increasing snowpack depth. As temperatures warm to ridgetop for Sun limit your exposure to significant slopes. Do not get taken by surprise. Long propagations may still be possible.
Warming temps through the storm created a punchy storm slab that is sitting on a variety of weak surfaces. Avalanche control proved that this slab is reactive and produced large avalanches. The slab may be more reactive in wind-exposed terrain. 
This last storm, and the forecast dump of snow this weekend, may wake a weak persistent layer up. This layer, buried ~1.5m deep, is still reactive in snowpack tests and if triggered will produce very large and destructive avalanches.
Sluffing out of steep terrain is a concern, particularly for ice climbers. Loose slides are overloading the snowpack in the alpine and have triggered slabs below.
Open areas at tree line and above are beginning to show signs of wind effect and slab development.

There are thin windslabs from the last storm on lee features that are reactive to explosives (size 1-2). Expect new windslabs to develop with incoming snow and wind over the weekend.
60 to 80 cm of warm/moist snow has formed a rider triggerable slab. Natural avalanches are expected this afternoon with rising temperatures and more snow load. Remote triggering is also a concern, watch out for adjacent slopes.
A deep weak layer buried at the end of January is down around 1.5 m. Although we have not observed any recent skier-triggering of this layer, artillery control triggered this layer on the west side of the park, releasing a size 3.5.
Recent storms with warm temps and West winds have created slabs and built cornices. Wet slabs are failing BTL and solar aspects, cornices and windslabs are failing at TL and above.
The weak February facet layer is now buried up to 170cm deep. Large loads such as cornices have triggered this layer where it is deep and it has failed with sluffing and heating where it is shallow. Long propagations are possible with this layer.
Solar heating will likely result in these events occurring to ridge tops Saturday. Warm temps as well as the rain expected Sunday will cause these events at low elevations. Be aware that these small events may act as the trigger for deeper slabs
Storm snow showing dangerous slab properties, use extra caution when entering steep open areas.
Wind slabs more prevalent in the Ice Fields area where moderate SW winds and mild temps have created touchy slab properties in all open areas.
Dense snow is overloading the Feb.10th interface and will continue through Sunday. 
Strong winds, new snow and warm temperatures are forming wind slabs in lee terrain and are likely to be triggered with light loads such as a skier.
80 to 100 cm of warm/moist snow has formed a rider triggerable slab. We are currently seeing natural avalanches in the storm snow, some running to end of runnouts. Minimize your exposure today by skiing in mature forest.
A deep weak layer buried at the end of January is down 1.8 to 2 m.&nbsp; Smaller avalanches could step down and trigger as large, high consequence avalanche on this layer.
Very little natural activity has been observed in the storm snow in the lower elevation bands. Loose wet slides will become the concern as the storm passes and the sun bakes the solar aspect.
We have had very limited observations in the alpine due to visibility. Be especially cautious as you approach open areas and ridge crests with visible wind effect.&nbsp;
The recent storm snow and wind slabs will slowly begin to bond to the lower layers in the snowpack but this will take some time. Choose conservative terrain with no overhead hazard until this has a chance to bond.
The Feb 10th layer continues to be reactive in many areas especially at tree line. Avoid any steep terrain until this has a chance to bond.
30cm of heavy snow with wind fell yesterday over much cooler and lighter snow. This combination is what caused a large avalanche cycle. Storm snow instabilities will still exist in the upper 1m and will need some time to bond to be trusted.
A sun crust down ~1m is well within the range of human triggering on south and west aspects. The February surface hoar/crust layer down ~1.5-2m which can reawaken with a heavy trigger such as a large cornice release.
There has been several avalanches observed&nbsp; running in the recent storm snow. Avalanche control produced 30 - 70 cm thick slab results on NE aspects.

In thinner snowpack areas, many avalanches are initiating as a storm or persistent slab and are stepping down to this layer.
The storm slab will settle over the next few days, but is currently very touchy. Most avalanches are initiating on this layer and quickly stepping down to the deeper weak layers.
Storm snow instabilities are present from snowpack tests yesterday. There is wind affect above treeline and lingering windslabs may exist in exposed areas.
Cornices have grown from the last storm. Strong solar radiation with warming temperatures will mean an increased hazard of cornice fall for today and tomorrow.
2 buried weak layers have been reactive this week. Down ~1m, is a sun crust on south and west aspects. The other is the other is Feb. surface hoar/crust layer down ~1.5m-2m which still shows wide propagation potential in snowpack tests.
There has been several avalanches observed running in the recent storm snow.
Very warm temperatures and rain to 2300 meters on March 8 and 9 has settled the near surface instabilities with cooler night time temps. Thin wind slabs may be present in some aspects on this layer.
The weak facet layer is now buried by up to 170cm in treeline and alpine areas and below treeline is found down 50cm. Many avalanches fell over the weekend on this layer and it is a concern that may persist for some time. Triggering is possible!

Storm slab is still touchy and has potential to step down to deeper persistent layers.
The recent wind slabs from the latest storm are settling out, but they will be stressed by today's sun and rapid warming. The first couple of hours of intense sun will likely bring activity to this layer.
Cornices will also feel a little heavier today with sun and warming. Give them a wide berth. A party of 4 nearly went tumbling off Castor Peak's west ridge when they triggered a cornice that they were standing on.
There are two layers of concern. The first is a sun crust on S-SW slopes, buried ~1m deep. The second is the Feb 10 surface hoar/facet complex, down 1.5-2m. Both exhibit sudden failures, meaning there is potential for wide propagation.
Recent winds have created a slab condition in the alpine. Cornices are growing and we observed two cornice triggered avalanches today.&nbsp;
Natural activity has slowed down on this layer, but we have seen large avalanches over the past few days with the new storm snow overloading the Feb.10th interface. In some cases we have seen this step down to the basal facets in thin snowpack areas.
Mod to strong Westerly winds will be stiffening the snow surface and transporting snow to lee aspects. These will be sensitive to human triggering for the next few days.
Watch locally for daytime warming in steep, solar features.
The surface slabs are settling out and bonding to the older interface, but if the temperatures rise more than forecasted, expect touchy conditions on south and west aspects.

In thinner snowpack areas, this layer is still touchy as shown by numerous large whumphs and sudden collapse results today. It is especially reactive on solar aspects where there is a buried sun crust and may be less reactive in deeper snowpacks
Recent moderate to strong west winds have stripped fetches and loaded the lees. Lee slopes will be quite touchy and the loading may be enough to trigger natural avalanches

Lots of new snow, with wind, through the weekend will form a new storm slab. This slab will likely be most reactive where it overlies suncrust, but will also bury small surface hoar. If triggered, this slab may also step down deeper.
New snow Fri is starting to build windslabs on lee slopes. The storm snow forecast for Sun/Mon will build these deeper. These will need some time to settle.
The layer down 70-170 cm is still active as demonstrated Thur with avalanche control work up Akamina. Any slope not yet slid should be a concern. Windslabs, cornices, storm slabs or wet loose avalanches could step down and result in large avalanches.
This layer is still touchy in thin snowpack areas (especially where there is a buried sun crust), and large whumps and sudden collapse results have been found. With limited observations this layer now seems less reactive in deeper snowpack areas.
Lee slopes will be loaded from recent strong westerly winds. With more wind and snow in the forecast, these wind slabs will increase in likelihood and size through the weekend.
With the new snow, expect the Feb 10th layer of facets, surface hoar, and some buried sun crust to &quot;wake up&quot;, especially in thin and variable snowpack areas.&nbsp;
We will have wind slab development in any exposed areas with the new snow and forecasted mod-strong west winds.&nbsp; Failure of these may step down to the Feb. 10th interface.
We've had a significant amount of snow overnight. Combined with the mild temperatures, the southerly winds which have started to pick up and the crust which it sits on, the new storm slab will be highly reactive to human triggering.
This sudden heavy snow load is likely to reawaken the deeper persistent weak layers creating very large avalanches. Avoid crossing avalanche paths until the storm ends and temperatures cool down.
As yesterdays avalanche indicates, the basal weaknesses are still susceptible to human triggering. Use caution in steep, shallow areas that have not previously avalanched.
Closely associated to the new storm slabs, wind-slabs will be located at higher elevations in direct lee areas. Because of wind transport the wind slabs will be thicker (up to 40cm) than the storm slabs and potentially more touchy.
The avalanche cycle in the alpine has eased from earlier in the week but we will see it ramp up with more snow on Saturday night. This loading pattern is looking perfect for increasing the size&nbsp; and instability of existing cornices.
The avalanche cycle in the alpine has eased off but we expect this to ramp up with the onset of heavy snow and strong winds on Saturday night.
Where wind slabs overly the February 10th facet layer very touchy conditions exist. This is borne out by numerous incidents of skier accidental and remotely triggered avalanches in the last few days.
The 35cm of snow that fell in the last day has been observed to travel far and fast when it fails. Loose snow slides are likely with any solar affect particularly at lower elevations.</span></p><p class="p_CC664AAA"><span class="s_AA239A9B">
65cm has fallen over the last 4 days with strong winds yesterday. On solar aspects this has buried a thick sun crust. Venturing out into larger terrain is not a good idea at this point as this new load will need some stabilization time.
Down around 1-1.25m is a buried crust from early March. Backcountry users have been reporting whoomphs and remotely triggering this layer prior to this latest storm. Extra caution on steep south and west slopes where the crust was well formed.
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.
Wind slabs can be found on sheltered lee aspects in the alpine and if triggered could step down and release a larger slide.
The 30-40cm of snow from the last few days is sitting on crusts or moist snow that could provide a poor bond. Daytime heating could trigger these instabilities on south facing aspects but they may persist on cooler north aspects for a few days.
Previous windslabs are lurking just under the surface and now there is a lot of snow available for transport to start building new ones.
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.
The Feb 10th layer continues to produce whumphs, natural and remote avalanches and skier triggered avalanches. It is especially sensitive in thinner or cross loaded snowpack areas and places with a buried sun crust.
The recent storm slabs are between 40 and 80cm thick. In general they seem to be bonding well but use caution in steep or wind loaded features.
Lingering storm slabs instabilities may exist from the last storm two days ago and the associated wind. 2 crusts have been recently buried by this. Caution in more exposed areas where the wind had a chance to stiffen the snow.
A weak layer from early March within the range of rider triggering may catch you by surprise. Triggering this layer is more likely on steep south and west aspects where the crust had a chance to fully form.
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.
We are seeing less activity with this problem as the days go by. It is still touchy and what is left is a low likelihood but high consequence situation if it is triggered.
The storms slabs will continue to settle. However, as they settle, they will become more cohesive and the likelihood of triggering will be the same for a few days yet.
The &quot;drought layer&quot; (Feb 10) has been sensitive in the past week, contributing to numerous large avalanches. Pay particular attention to moraines at treeline and crossloaded features in the alpine.
With lots of new snow available for transport, new windslabs will be forming in exposed areas as the winds increase in the next couple of days.
35cm of recent snow is settling rapidly. Although this snow appears to be bonding well, caution is warranted in steep terrain. It is a good idea to test the storm snow interface prior to committing to your line.
The recent storm snow has been redistributed by winds. The resulting soft slabs sit atop various old surfaces, including crusts on solar aspects and small surface hoar on northerly aspects. The slabs will remain reactive for a couple more days.
The early March crusts are buried by over a metre of snow, but are still triggerable by people. They are more likely to fail on steeper S and W aspects.
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 &quot;drought layer&quot; (Feb 10) has been sensitive in the past week, contributing to numerous large avalanches. Pay particular attention to moraines at treeline and crossloaded features in the alpine.
With lots of snow available for transport, we suspect recent windslab formation in the alpine in exposed areas.
35cm of recent snow is settling rapidly. Although this snow appears to be bonding well, caution is warranted in steep terrain. It is a good idea to test the storm snow interface prior to committing to your line.
Activity on the Feb.10th of facets, surface hoar and buried suncrust is starting to taper off, and it is a lowered likelihood with large consequences scenario.  Some slides have been observed to step down to ground in thin snowpack areas.
Storm slabs formed in the last few days will be less sensitive to triggering as time goes on.  Forecast snow may build on these on Thursday.
The recent storm snow is settling into a cohesive slab, particulary in wind affected areas. Various weak layers within, and just below, the slab exist and may be triggered by skiers or snowboarders. It may become more reactive during sunny periods.
This layer is patchy which makes it difficult to predict. It is likely to be most reactive on solar aspects where it is comprised of a sun crust with surface hoar. If triggered it has properties and is deep enough to result in a large 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 &quot;drought layer&quot; (Feb 10) has been sensitive in the past week, contributing to numerous large avalanches. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Windslabs are forming in wind prone areas below lee ridgelines at treeline and above.
Another 15 cm of new snow fell on top of this past weekend's 35cm storm. Although this snow appears to be bonding well, caution is warranted in steep terrain. Test the storm snow interface prior to committing to your line.
Feb 10 shears tightening up in deep snow pack areas west of the divide. In shallower snowpack areas this interface still producing whoomphing and easy to moderate shears.
Recent snow combined with mild temperatures and West winds have created soft slabs. These slabs are sitting on a variety of surfaces including rain crusts, sun crusts, old wind slabs and the interface to the previous storm snow and are 25-40 cm deep
New snow is sluffing off of very steep terrain and moving with skiers on steep slopes. Manage your group carefully and be aware of your sluff. Avoid confined terrain features such as gullies where these small slides could focus and gain more energy.
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.
Snow amounts have slowly been accumulating over the last few days and storm snow instabilities may catch you by surprise. Caution on unsupported slopes or wind affected areas. This new snow is likely to produce some fast sluffing on steep slopes.
This layer is deep enough to cause a large avalanche and shallow enough to be triggered by people, a dangerous combination. It's been most reactive on solar aspects where the crust is thickest and most likely to be triggered from shallow snow 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.
Slowly this layer is becoming less reactive, but it remains a concern. Field tests, particularly on southern aspects, confirms this. It's now down 80-120 cm and more likely triggered from thinner areas or by larger loads.
A 5 cm thick suncrust with facets on top exists on solar aspects with moderate sudden shears and is down approximately 40 cm.. An avalanche triggered on this layer could step down to the Feb 10th layer resulting in a larger avalanche.
Confined to immediate lee of alpine features.
The &quot;drought layer&quot; (Feb 10) has been sensitive in the past week, contributing to numerous large avalanches. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Windslabs are forming in wind prone areas like below lee ridges at treeline and above.
Trickling snow over the last 4 days amounted to 60cm at tree line. Instabilities in the upper snowpack from the recent snow load may exist particularly in exposed areas that saw some wind.
Reports of whoomphing and natural activity observed on this layer yesterday indicate it's volatility. This layer is deep enough to cause a large avalanche and shallow enough to be human triggered, a dangerous combination.
Large triggers have produced big avalanches on this layer, down ~2m. It remains on our watch list and it's another reason to avoid shallow snowpack areas.
We are finding moderate to hard sudden collapse results on the Feb.10 interface. Thin and variable snowpack areas will be the easiest places to trigger this interface.
A 5cm thick suncrust with facets on top exists on solar aspects with moderate, sudden shears down 40-60cm. An avalanche triggered on this layer could step down to the Feb.10 interface causing a larger avalanche.

Windslabs are forming in wind prone areas like below lee ridges at treeline and above and cross-loaded gulley features.
Storm slab instabilities may exist and may pop with human triggering, solar warming and newly formed soft slab in the lee of ridge crests.
The Mar 2nd crust is dwn around 1.25m. The slab overtop the weak layers down 1-1.5m continues to settle and become more cohesive.
The Feb 10 layer may be a concern with very large triggers or thin snowpack areas in rocky terrain.
The &quot;drought layer&quot; (Feb 10) has been sensitive in the past week contributing to numerous large avalanches. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Windslabs continue to form and be covered by intermittent snowfall. Pay attention to wind affected terrain above treeline.
The Feb 10 layer will be touchier in the Eastern portion of the forecast area, less in the West. In addition to Feb 10, the Mar 13 layer, a suncrust on South aspects, can be found down 40-60cm. Snowpack tests on this layer produced moderate results.
Storm slab instabilities newly formed soft slab in the lee of ridge crests may exist and pop with human triggering.
Snowpack tests yesterday show the Mar 2 layer down ~1m to still be reactive with large consequences if triggered. Shallow snowpack areas, like slopes that have lots of rocks poking out, seem to be the most likely areas for this to happen.
Another deep weakness in the snow pack is the February surface hoar/crust layer. Large triggers, such as a cornice fall or a running avalanche, will be needed to step down to this layer.

The Feb 10 layer is touchier in the eastern portion of the forecast area, less in the west. In addition to Feb 10, the Mar 13 layer (suncrust on south aspects) can be found down 30-60cm. Snowpack tests on this layer have produced moderate results
The late March sun is packing a lot of punch. If the sky doesn't cloud over tmrw, we may see some natural activity out of steep rocky solar terrain.
With significant warming Tue and  incoming precipitation for the rest of the week, expect these slabs to become more reactive. Small changes in aspect and elevation seem to change the nature of these slabs so monitor what you are skiing on closely.
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 early March weak layer down ~1m is reactive in snowpack tests with hard sudden results. We still see sporadic large avalanche events that fail on this layer. Choose supported slopes that have uniform snow cover.
Deeper in the snowpack is the February surface hoar crust layer. Large triggers, such as heavy snowfall or cornice fall will be needed to get this layer to fail.
The &quot;drought layer&quot; (Feb 10) has been quietly dormant. Expected snowfall this week could 'wake' this layer up. Pay particular attention to moraines at treeline and cross-loaded features in the alpine.
Ever present in the forecast area, expect slabs in wind prone areas like below lee ridges at treeline and above and cross-loaded gulley features.
The Feb 10 layer is touchier in the eastern portion of the forecast area, less in the west. In addition to Feb 10, the Mar 13 layer (suncrust on south aspects) can be found down 30-60cm. No shears were found on Mt Field today during snowpack tests.
New snow overnight will have formed soft slabs in alpine and tree-line lee features. In wind-sheltered areas, it will likely be good quality skiing.
The early March weak layer is still reactive with hard, sudden planar results in tests. Sporadic large avalanche events are still occurring on this layer, so heads-up with the new loading overnight. Stick to supported features today.
Lingering deep in the snowpack is the Feb 10 surface hoar/facet/crust layer. A large event occurred north of Rogers Pass 2 days ago, reminding us that a large trigger could create a very widely propagating avalanche with devastating results.
Expect to find new slabs in wind prone areas on lee ridges at treeline and above and in cross-loaded gulley features. Loading continues in these open areas and can overload the slope quickly.
Lee features continue to load and the potential exists to trigger these deep instabilities. Carefully evaluate your time spent under overhead hazard before committing to terrain.
There are two layers of concern in the upper meter of the snowpack that continue to produce shears in isolated areas and have a high degree of uncertainty. Be very mindful of this problem in areas that have not previously avalanched.
40 cm of loose snow is available to be blown into soft slabs by the wind. So far this storm has brought light winds, but we expect small windslabs to develop at the highest elevations where there has been some wind.
Loose dry sluffs are running easily and gaining mass as they progress down the slope. Generally only small slides are anticipated, but watch your exposure to cliffs and trees as these can easily knock you off your feet.
Yesterdays new snow bonded poorly to the snow below and became very reactive as the temps warmed up. Loose, moist avalanches were easily triggered by skiers. These avalanches were at the smallest &quot;knee-twisters&quot; but some grew to size 2.5.
Weak layers from early March, now buried a meter deep, are still reactive in tests. They are most likely to be triggered on solar aspects where sun crusts exist. Smaller avalanches may step down to these layers, resulting in a big avalanche.
A persistent weak layer from late Jan/early Feb remains a serious concern as it continues to be responsible for very large avalanches. This layer is variable in its distribution, is now buried up to 2m deep, is hard to trigger, and harder to predict.
Expect slabs in wind prone areas like below lee ridges at treeline and above and cross-loaded gulley features.&nbsp;
he &quot;drought layer&quot; (Feb 10) has been dormant for over a week now. Warming temperatures and continued wind-loading could 'wake' this layer up.
The new snow fails easily on steep slopes: Manage you group carefully and avoid confined features such as gullies.
Up to 25cm&nbsp; of new snow over the March 26 interface will quickly form a slab with mild temps and the forecast winds. On solar slopes these slabs will be found over a crust and may be particularly touchy.
70 to 110cm of snow is now settling above the early March Crusts. Variable shears persist in these slabs and they are well worth bearing in mind particularly as heating becomes more of a factor in the days and weeks to come.
Watch out for sluffs, as several big ones have been noted today and yesterday - particulary on steep, south facing terrain where a firm suncrust underlies this new snow. Check your exposure and make sure you don't get pushed into any obstacles.
In areas of the park with a weaker snowpack we remain concerned about the Feb 10 layer of facets and surface hoar located in the middle of the snowpack. This layer remains, and caution is advised in specific areas such as the burns in Kootenay Park.
20cm of new snow from earlier this week has bonded poorly to the snow below. It is especially reactive on solar aspects, where it is rapidly destabilized by even a little bit of sun. On lee aspects, soft slabs may exist from windloading by SW winds.
Weak layers from early March, now buried a meter deep, are still reactive in tests. They are most likely to be triggered on solar aspects where sun crusts exist. Smaller avalanches may step down to these layers, resulting in a big avalanche.
A persistent weak layer from late Jan/early Feb remains a serious concern as it continues to be responsible for very large avalanches. This layer is variable in its distribution, is now buried up to 2m deep, is hard to trigger, and harder to predict.
Wind slabs in immediate lee areas have the potential to step down and create large full depth avalanches.
This avalanche condition is quite uncertain and large slopes should be treated with caution. Especially those with recent wind loading or those that face the sun.
More sluffs observed today on South and North aspects, up to size 2. Watch your exposure to steep terrain overhead, especially if the wind gusts pick up.

This is not yet a wide spread issue and only a few soft wind slabs to size 2 were observed today in the immediate lees of terrain. Monitor slab development with wind gusts tomorrow as this may develop into more of a problem.
A weak layer down 20-30 cm is still reactive to skier-triggering. Use caution on unsupported features and convex terrain. Watch for changing conditions as temperatures warm up today and surface crusts deteriorate.
Weak layers from early March, now buried a meter deep, are still reactive in tests. They are most likely to be triggered on solar aspects where sun crusts exist. Smaller avalanches may step down to these layers, resulting in a big avalanche.
Expect slabs in wind prone areas like below lee ridges at treeline and above and cross-loaded gulley features.
The &quot;drought layer&quot; (Feb 10) has been dormant for over a week now. Warming temperatures and continued wind-loading could 'wake' this layer up.
In areas with uneven, shallower or weaker snowpacks, we remain concerned with the Feb 10th midpack layer of crust/facets/surface hoar, and the basal layer. Choose conservative, well supported terrain in these areas.
These are mainly confined to the immediate lees of ridges. Monitor slab development with wind gusts tomorrow as this may develop into more of a problem.
The recent storm slabs have been slow to bond and remain in the skier triggerable range. Lee aspects in the alpine and treeline elevations are the more likely areas for a slide to propagate. Low elevations may have possible moist sluffs.
more reactive on solar aspects.
The Mar 2nd crust is down around 1.25m. The slab overtop the weak layers down 1-1.5m continues to settle and become more cohesive. The Feb 10 layer down 2m is a major low probability high consequence concern.
Although this problem still remains, triggering still remains possible. As time goes by it will become less likely that people will be able to trigger this layer.
Some light wind at the ridge tops has produced windslabs. Likelihood of triggering and layer thickness is uncertain.
Expect slabs in wind prone areas like below lee ridges at treeline and cross-loaded gulley features in the alpine.
Although the Feb10 layer (down 60-90cm) has been dormant in the past several days, it remains a concern and has produced several large avalanches this week. Large triggers and shallow areas may still produce avalanches failing at this interface.
We`ve had some incremental loading, 30cm in 3 days. The sun is expected to poke through the clouds today so expect conditions to become more dangerous as the day progresses, specially on the solar aspects if that happens.
Many weak layers are buried within the snowpack in the upper 2m. These are all deep enough to cause large avalanches that will inflict significant damage. Shallow areas and day time warming are most likely to trigger them.
Expect slabs in wind prone areas like lee ridges at treeline and cross-loaded gulley features in the alpine.
Although the Feb10 layer (down 60-90cm) has been dormant in the past several days, it remains a concern and has produced several large avalanches this week. Large triggers and shallow areas may still produce avalanches failing at this interface.
Several avalanches have been observed deep in the snowpack over the past 24-hours. Avoid shallow areas where the snowpack is weakest. These avalanches are very unpredictable, so choose terrain that avoids steep, rocky slopes.
Over 60 cm of snow has fallen over the past week, and that snow has now settled into a cohesive slab. Caution is advised in all avalanche terrain at treeline and above, in particular one should avoid exposure to avalanches during the heat of the day.
Recent warm temps and wind have contributed to the formation of a soft slab that has failed naturally over the last few days. This slab will become more sensitive to triggering with heating and could be triggered in steep or unsupported terrain.
Daily heating and the sun will create moist snow at low elevations and on solar aspects. Intense periods of radiation will trigger avalanches or cause cornice failures that could trigger avalanches as well.
Strong solar radiation is expected today. Think about getting off sun exposed slope when the crusts that formed overnight break down. Watch for loose avalanches below cliffs as an indication that things are becoming dangerous.
The sun will get deep into the snowpack today and could reawaken one of the many buried weak layers. Avoid slopes where rocks are evident on the surface as they are likely to attract more heat to trigger those layers.
Manage your groups exposure to the overhead cornice hazard. Remember that even though you may be on a shaded north aspect, if there's a cornice above you on the ridge it will be baking in the sun.
This problem represents a classic low likelihood high consequence situation. Areas that have not previously avalanched will be more susceptible to triggering.
Storm slabs will continue to settle. These slabs will be touchy on Southern aspects in the afternoon.
Recent storm snow has settled into a slab and is touchy on steep, unsupported terrain.
There is a fair bit of uncertainty associated with weak mid-pack layers.&nbsp; Although isolated, there have been numerous natural avalanches in the past 2 days that have failed in the mid-pack or on the ground.&nbsp;
The April sunshine is strong. If it pokes through the clouds today, expect solar aspects to destabilize quickly, especially at lower elevations.
There are numerous sliding layers buried in the upper 1-1.5m of the snowpack. If we see any strong sunshine today, there could be avalanches stepping down to these layers.
The spring-time cornices are large and looming overhead. They weaken with sunshine and warming temperatures, so plan your day to be away from them as things warm up.
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.
Strong winds in front of Thursday's storm, combined with another 10cm of snow will make for small, but touchy windslab conditions at the higher elevations by mid to late afternoon on Thursday.
The upper 1-1.5m of the snowpack has numerous sun and temperature crusts within it. These may become sliding layers with day-time warming and the possibility of a strong April sun popping onto the slopes.
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. 
With increased winds and some snow in the forecast, watch for wind slab formation in the lees of ridge crests over the next 24 hours.
This layer may be buried up to a meter below the surface in wind loaded areas. In such areas the upper snowpack may be providing bridging strength. Areas of shallow snowpack particularly adjacent to wind loaded slopes are of greatest concern.
Soft slabs were observed in the Alpine by a field team yesterday in the Asulkan drainage, and rising winds this morning will likely create more. Avalanche activity this morning is attributed to this problem.
Be aware that small avalanches have the ability to trigger larger step down avalanches.
Moderate SW winds in the Icefields are creating windslab conditions along alpine ridgelines cross-loaded features.
Results from this layer were seen on March 31st during a earlier warming event after a prolonged cool period.
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.
Wind slabs 15-25 cm thick were found in immediate lee terrain and failed easily in snowpack tests.
20cm of new snow with some added wind created some reactive conditions at the higher elevations these past two days. Watch for cracking and more 'slabby' feeling snow as you venture on the upper mountain specially in the lee of ridge features.
Many crusts on solar aspects are buried within the 1m range. At this depth they can be triggered by humans. Avoid shallow snowpack areas where it is most likely to initiate an avalanche on this layer.
Skiers looking for dry snow on the shaded aspects should frequently test the surface layers. A shear persists down about 30 cm with preserved stellar snow flakes and surface hoar. Caution in steep and unsupported terrain is advised.
Daily heating and the sun will create moist snow at low elevations and on solar aspects. As crusts break down avalanches will result. Cornices will also be affected by this heating and could trigger persistent slabs.
With significant heating in the forecast for Monday and Tuesday deep slabs may become active. Large loads such as falling cornices or smaller avalanches could trigger large avalanches on the March crusts or even the February facets.
Southwest winds are creating windslabs along alpine ridgelines and cross-loaded features. Their thickness and interface is variable depending on aspect, elevation, and localized weather influences.
Weak basal facets and depth hoar remain intact and should be on your radar. This deep weakness is difficult to predict and has severe consequences. The snowpack above appears to be bridging the weakness; however, allot of spatial variability exists. 
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
Isolated wind slabs in the lees of alpine ridge crests will still be susceptible to human triggering in the short term.
The snow load has steadily increased with winds up high. A surface hoar/crust layer is buried 30-40cm depending on aspect. As this snow becomes moist it will become more susceptible to human triggering.
The upper snowpack consists of many buried crusts on solar aspects. Triggering these layers is most likely from slopes where the snowpack is shallow and/or if there is strong solar radiation even if this is for brief moments.
Windslabs have developed along ridgelines and crossloaded features. Their thickness and interface is variable depending on aspect, elevation, and localized weather influences. It may be present on S aspects over slippery sun crust. Evaluate for this.
Weak basal facets should be on your radar. It is difficult to predict and would have severe consequences if triggered. Allot of spatial variability exists. Field team reports large tree shaking whumph Sunday, in the trees, E aspect, at 1800m.&nbsp;
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.
Isolated wind slabs in the lees of alpine ridge crests will still be susceptible to human triggering in the short term.
As freezing levels rise things will become more unstable particularly in steeper terrain and at lower elevations. Snow that is very heavy and creates pin wheels is an indicator that snow stability is decreasing.
We've had enough snow in the past few days to warrant some caution up high. Winds have been steady and combined with rising temperatures things will slab up a some more.
The deeper instabilities that exist in our snowpack can reawaken with the increase in temperatures or added weight of snow/rain. Avoid those shallow snowpack areas where triggering these layers is most likely.
Skiers looking for dry snow on shaded aspects should frequently test the surface layers.&nbsp; A shear persists down about 30 cm&nbsp; with preserved stellar snow flakes and surface hoar. Caution in steep and unsupported terrain is advised.
Daily heating and the sun will create moist snow at low elevations and on solar aspects. Intense periods of radiation will trigger avalanches or cause cornice failures that could trigger avalanches as well.
Although unlikely, a large load such as a cornice failure or another avalanche could trigger all of the snow above these strong crusts. Significant and sustained heating or rain may also allow these slabs to become active such as is forecast Monday.
Windslabs have developed along ridgelines and crossloaded features. Their thickness and interface is variable depending on aspect, elevation, and localized weather influences. Incoming winds and snow Tuesday afternoon will add to this condition.
The deep nature of this weakness is difficult to predict and would have severe consequences if triggered. A lot of spatial variability exists. Field team reports large tree shaking whumph Sunday, E aspect, at 1800m.
">Daily heating and the sun will create moist snow at low elevations and on solar aspects. As crusts break down Loose Moist or even Wet Slab avalanches will result. Cornices will also be affected by this heating and could trigger persistent slabs.

Large loads such as falling cornices or smaller avalanches could trigger large avalanches on the March crusts or even the February facets.
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.
Moist surface sluffing and small wet slabs are likely on all aspects and elevations as freezing levels climb on Tuesday.  Stick to mellow terrain as even a small wet slide can be very powerful.
Several cornice failures have occurred in the region over the last couple days. These can act as large triggers and cause failures on the basal facets. Warm temperatures and strong winds will cause this hazard to increase over the next few days.
With high freezing levels, snow is particularly unstable on steeper terrain and at lower elevations. This heavy snow will pinwheel down the mountain, gathering mass, and is a clear indicator of snow stability decreasing.
The recent storm snow has not fully bonded to the underlying crust and surface hoar layer. Combined with the warm temp's, it has become a touchy surface slab that is reacting in higher elevation lee areas.
We may see the deeper instabilities reawaken with the warm temperatures, and possibly rain, moving into the snowpack. Try to avoid shallow, thin areas where a person could trigger a deeper weakness.
The warmer temperatures have the potential to wake this layer up, as demonstrated today on Cascade Waterfall (size 3).
Low elevation south aspects will be particularly susceptible to loose wet avalanches. This problem will be most active in the warm afternoons.
Cornices are quite large at the moment. Try to minimize your exposure to these features, especially with the warmer temps in the afternoon.
Continued wind loading and warming temperatures have increased the triggering sensitivity of this weakness. Strong SW winds on Tuesday were present across the region but most noticeable in the Columbia Icefields area
Strong SW winds on Tuesday have created slab conditions. SE aspects where buried sun crusts may provide a sliding surface should be approached with caution. Thin slabs will likely step down to the basal weaknesses near ground producing large slides.
High to extreme winds in the last 24 hours have formed wind slabs in exposed Alpine and Treeline areas where the snow was still soft and dry. Pockets of good dry snow may be found in protected North aspect areas above 2400m.
Be aware that step down avalanches are possible if storm slabs or wind slabs are triggered in wind loaded areas.
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.
Several natural cornice failures have been observed in the last two days caused by new snow loading and warm temperatures. Minimize exposure to overhead cornices.
Gusty SW winds have formed new wind slabs in immediate lee areas.&nbsp;
Most avalanches regardless of initial form are stepping down to ground. These are most common from shallow snowpack areas where there is little bridging strength in the midpack and the thermal energy is greatest. Rocky areas are also dicey.
Strong South and Westerly winds are transporting the 10-15cm of new snow from the 8th. Rain fell below 1,800m. Field tests at 2,300m produced an easy shear above an old sun crust on the 9th. At lower elevations the slab is less well developed.
There may be lingering surface slabs at alpine and tree-line elevations, due to the strong winds accompanying the last snowfall.
The large size 3.5 from Moccasin Flats 36 hours ago shows the persistent slabs have not gone away. Larger triggers, like cornices or surface avalanches, may step down to deeper layers.
Most observed avalanches in the past week are stepping down to this layer. Frequently observed between 2200-2400m and triggered by  wind loading, cornice falls of solar exposure. Most common in shallow areas or near rock outcrops.
Strong to extreme southerly winds continue to form slabs dating from early April. Slab activity stepping to ground quickly. Buried sun crust can present a sliding layer as seen at 2300m near Marmot. Sheltered snow can be found at treeline and below.
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.
April is cornice season, and on most days we observe a cornice failure. Expect these on an almost daily basis this time of year, as the mountains shed their snowpack. Try to avoid traveling under cornices, or do it early while it's still cold out.
With poor freezes the last few nights and clear days, solar heating has allowed for widespread activity. Expect this activity to dissipate with cooling and clouds but to resume as the sun returns.
West winds continue to transport snow at treeline and above on shaded aspects. Expect to find slabs to increase in their development as you ascend into the alpine
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.
The 10-15cm of snow from a few days ago was redistributed by strong winds, creating windslabs in exposed alpine and tree-line locations.
Without a good refreeze, there is less structure to the snowpack to prevent it from stepping down into the lower persistent weaknesses. The large size 3.5 from Moccasin Flats 2 days ago illustrates the potential destructive force lingering out there.
Colder weather will add a little more stability to the snowpack. It is still too early to move out onto big alpine lines.
Most observed avalanches in the past week have stepped down to this layer. Triggers include: wind loading, cornice fall and solar exposure. Most commonly triggered from shallow areas or near rock outcrops.
Gusty moderate SW winds continue to form slabs dating from early April. Sheltered snow does exist at treeline and below.
New snow in the past weak is possible to skier-trigger.  Watch for hard, wind-deposited snow on lee features in the alpine.  Storm slabs failing on crusts is possible at lower elevations.
Weak layers buried deeply in the snowpack are still releasing naturally and producing avalanches up to size 3.5.  Warm temperatures and solar inputs elevate this hazard. Large, heavy triggers like cornice falls could trigger a large avalanche.
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.
With tomorrows clear skies and sunshine we will likely see loose wet slides on steep S aspects in the afternoon.  Cornice failures are also possible as things warm up. Plan to finish your trips by early afternoon.
Fat windslabs are present below ridgelines and on cross-loaded features. The bond between these slabs and the snow beneath is uncertain, however, warm temps and solar exposure will weaken them.
Large triggers such as cornice fall or smaller slab/loose wet avalanches may trigger this weakness. Skier could trigger from shallow areas or near rock outcrops.
Slopes that have been baking in the sun can fail as a slab on crusts and on higher alpine elevations on North lee aspects.
The Mar 2nd crust and Feb 10 layer can be triggered by heavy loads such as cornices or loose wet slides, a likely scenario with the forecast strong solar inputs.
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.
Low elevation solar aspects are the main features to be aware of. Of course, if it remains cool little activity should be expected, add heat and south slopes could come alive with avalanche activity.
Windslabs are present below ridgelines and on cross-loaded features.  No avalanche activity has been observed on these slabs but field teams have not tested bonding.
If the sun has been baking slopes, there is the possibility of a slab avalanche failing on buried crusts. In the alpine slab avalanches could be triggered on lee North apects.
The Feb 10 layer is the monster that can be triggered by heavy loads. It is still a 3-5cm thick sandwich complex layer of SH, FC and crusts.
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.
Spring is cornice season and a great time to try and totally avoid exposure to cornices. If you must go under one, move quickly and reduce your risk by reducing your exposure time.
Snow flurries on Tuesday will add to the danger near ridge tops and into the alpine. Good skiing will likely exist in sheltered locations at lower elevations.
Even short bursts of solar heating can rapidly affect the snow this time of the year. With mild temperatures in the forecast, watch for rain to affect the snow at lower elevations.
Isolated and thin windslabs have been built in open features and can be found poorly bonded to crusts. Watch for these to grow or to become hidden with incoming snow.
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.
Thin, variable slab is present in the alpine and tree-line. It appears to be bonding with the underlying interface, but some pockets in lee features may surprise a person.
Deeper persistent layers will require a large trigger to initiate, or a couple of people hitting a thin, weak spot in the snowpack.&nbsp;
This condition is most prevalent in the alpine near ridges and open bowl features. Near treeline the slabs are most threatening when sitting over buried sun crust on southerly facing slopes.
2 weak layers within our snowpack, down ~1m and ~1.2m that are producing tests results to be concerned about. Whoomphing and cracking may not be as prevalent due to the depth of the layer but if triggered the slab is likely to propagate.
Lingering shallower slabs at higher elevations may still be out there.
The primary problem in the snowpack is the interface between the recent storm snow and the November 6th and 24th facet/crust interfaces. This problem is the culprit for the vast majority of the avalanches in the past week. Watch for remote triggers.
The wind affect will be encountered above treeline and above in wind exposed terrain.
Storm snow will continue to be redistributed by predominantly NW winds at ridge tops in the high alpine . Storm slab could become more active if warmer temps and or higher winds develop.
Dry loose snow avalanches are still possible in steep rocky and unsupported terrain.
Persistent weak layers buried down ~1m and ~1.3m are cause for concern. As temperatures rise the likelihood of triggering will increase and they are capable of producing very large avalanches. Be especially cautious on planar open slopes.&nbsp; </span></p><p class="p_CC664AAA"><span class="s_AA239A9B">

A heavy storm slab is building rapidly with moderate precipitation, warm temps and strong winds. It will bond poorly to the snow below and natural avalanches are occurring. Storm slabs may step down deeper resulting in very large avalanches.
Persistent weak layers that were very reactive earlier this season are expected to wake up again with the rapid loading that is occurring. These layers are capable of wide propagations and producing very large and destructive avalanches.
Recent wind loading has produced new touchy wind slabs on lee and cross loaded features in sheltered areas.
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.

Cornices are large and continue to build with warm temps and wind. Incoming rain on Friday may be the trigger that causes cornices to fail. These will have plenty of new snow to entrain and may trigger wind slabs. Be aware of what is above you.
Dry snow persists on north aspects at upper elevations, watch for loose dry avalanches in steep north facing terrain.
Persistent weak layers deep in the snowpack continue to cause uncertainty, despite the surface layers being remarkably strong. Continue to avoid exposure to large slopes. Patience is a virtue as we wait for a melt/freeze cycle to change anything.
April is cornice season, and we are getting regular reports of cornices failing. Mature cornices can propagate much further than you expect, so give them a wide margin when traveling on ridges and get up early and hurry if you must travel below them.
The snowpack is generally unstable, despite the strong feel of the surface layers. This next warm-up will again test the snowpack and we expect increased avalanche activity over the next several days. Patience is a virtue with this kind of problem.

New storm snow needs time to bond to the underlying firm temp crusts. Where winds have redistributed it in lee features, expect the slabs to be reactive to light human loads, especially at ridge-top, over convexities, and large planar alpine slopes.
Large cornices guard the high alpine ridges and are HUGE. If these fail, due to direct sun, human loading, or wind loading, they could dig down into the snowpack and trigger deep persistent slabs. Always keep an eye on the high alpine ridges.
The snowpack is slowly gaining strength, but the weak basal facets continue to produce sudden collapse results and can produce large avalanches with large triggers. Stick to planar, supported slopes with a deeper snowpack if entering steep terrain.

Cornices remain impressively large, and will increase in size and sensitivity with forecast snow, warmth and wind on Thursday.
Moderate gusting to strong winds from the NE this morning and last night are building wind slabs in the alpine and at the upper end of treeline. Winds are forecast to switch today to the SW and stay in the moderate range.
Storm slabs are most volatile where they overlie a crust on solar aspects. 50+cm of new snow accompanied by warm temperatures and wind fell over the last week in the alpine and upper end of tree line.
Cornices are always unpredictable! However we are seen cornices fail in the HWY corridor and in the back country on a semi regular basis. With naturals triggers easing, back country enthusiasts would be the likely trigger.

Winds have switched around to the SW and are building and redistributing surface wind slabs in alpine and tree-line lee features. These slabs may be quite sensitive to trigger if they sit upon a firm sun or temperature crust.
There are multiple crusts in the upper metre of the snowpack, each providing a smooth sliding layer if avalanches dig down and trigger the deeper layers. Solar aspects are the biggest concern with day-time warming and a powerful April sun.
The cornices are as big as they are going to get. Predicting their failure is tricky, but warming, heavy intense loading, or direct sun will weaken them. They have triggered some very large natural avalanches in and near Rogers Pass recently.
15 cm of new snow with moderate SW winds will create reactive alpine windslab on lee slopes.&nbsp; If triggered, these could step down to the deep persistent slab resulting in very large avalanches.

Rapid warming in temperature or intense solar will increase the likelihood of cornice failure.
Storm Slab pockets exist lee to West and SW winds, especially immediately behind ridge crests, outcrops, and islands of trees (&quot;immediate lees&quot;). It is possible a person or solar radiation could trigger these. This problem will lessen over time.
Cornices growth has continued. Periods of intense solar radiation will increase the chance of these failing naturally. Of course, they are most likely to break if walked upon.
Loose Wet avalanches are possible on steep slopes on SUNDAY, as strong April Sun warms recent, soft surface snow. Expect this to be most pronounced were the most new snow lies: Easterly aspects/upper elevations in the Western portions of the park.
