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.
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.
Two avalanches were triggered by the sun today.

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.

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.
Spring sun is gaining in intensity. Expect solar aspects to shed snow during the heat of the day, especially when the skies are clear.
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.
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.
Expect slabs in wind prone areas like below lee ridges at treeline and cross-loaded gulley features in the alpine.
Intermittent breaks in the cloudy weather is consistently producing loose dry sloughing to size 2 as the sun hits recent storm snow.
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.

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.
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 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.
Low elevation areas may see avalanche activity with the day-time warming, especially if the sun pops out.
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. 
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.
This layer was seen to wake up and produce large avalanche under the influence of strong solar radiation. Convective weather patterns can produce short lived cloud clearances allowing intense solar exposure. Cornice failures can trigger this layer.
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.
If the sun comes out or if there is a rapid un-forecast rise in temperature watch out for loose wet avalanches.
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.
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
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.
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.
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.
With cooling temperatures this condition will stabilize. Rain and solar exposure will increase the danger. Weather conditions will be variable across the region. Snowballing and pin wheels should be regarded as signs of deteriorating conditions.
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.
Be cautious of lower elevation areas that have no crust formation from overnight. Loose avalanches are possible there.
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.
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.
If the sun comes out for prolonged periods today, we will likely see a rapid deterioration of the surface crusts. Start early if you are exposed to solar aspects, especially at lower elevations.
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.
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 cloudy skies overnight prevented a decent crust development. Expect lower elevation snow surfaces to be soft, with temp's getting close to isothermal, creating an unstable snowpack.
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.
Warm temperatures and solar inputs will deteriorate snow stability today as avalanche hazard rises in the afternoon.  Watch for terrain above you getting headed through out the day and use safe travel techniques to manage your group.
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.
A melt freeze crust is present with wet to moist snow beneath. The crust will deteriorate by mid afternoon and and avalanches are likely after this time. Steep solar aspects have the greatest likelihood.
Intense solar inputs will weaken last nights refreeze quickly and a loose wet cycle will likely start in the early afternoon.
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.
Later in the afternoon, loose moist/wet avalanches may start to come down if the sun is out and there is no cloud cover.
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.
On Tuesday expect this problem only on lower elevation, sun exposed places. Watch out in steep cliffy areas or steep forest in the afternoon.
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.
Low elevation areas are relying on a good overnight freeze to keep the snowpack together. There was not a strong freeze last night, so expect the surface crust to break down with light rain and the occasional glimpse of strong April sunshine.
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;
Although the forecast is calling for cooler, cloudier conditions, if the sun comes out, it will be strong and can destabilize the snow quickly. Also, be careful at lower elevations if it is raining.
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.
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">

Mild temperatures and westerly flow will cause wind slabs to develop in exposed areas at tree line and above. Watch for pockets of hard slab near ridge tops and on cross loaded features.
Thin windslabs can now be found at treeline. This slabs are thin and very localized and are easy to stumble into as they appear mid slope in front of you. With the warmer temps expected these slabs may become more sensitive before they improve.
These slabs taper radically with elevation and are sitting on a thick crust. Large slides resulted from failures in the recent storm snow over the crust that extends to around 2300m. These slabs may become easier to trigger with the expected heating.
At high elevations cooler temps have only allowed thin crusts to form above the weak November Facets which may remain a possibility for triggering for some time. Use caution TL and above especially in thin or variable areas.

70cm of storm snow since the New Year with continued snowfall today. The surface snow is likely to sluff rapidly in steeper terrain and effect anything down slope of your location ie other skiers and riders.
70cm of storm snow since the New Year, moderate south winds and warming temperatures all translates into a settling surface slab. This will be most likely in highly wind exposed areas such as ridgelines and crossloaded features.
The December 17th surface hoar layer is still a real concern in the snowpack.  The significant storm snow load should be increasing the probability of triggering this deeper weak layer.  This layer is most prevalent at treeline elevations.
Total of 30 cm of snow since Jan 2 is mostly unconsolidated, but expect slab formation at higher elevations. Shears in this storm snow were occurring within the upper 25 cm. Any wind or warming will increase this problem dramatically.

A touchy storm slab exists, with 30-50cm over a crust. On lee and cross-loaded features it's up to 1m deep. Yesterday skiers easily to triggered several size 2's and one size 3. They occurred in predictable places; steep slopes with a convexity.
A series of crusts on solar aspects, buried up to 1.2 m deep, remain a concern. Tests generally take a hard force but continue to produce sudden planar results. This suggests that smaller avalanches, or cornice failures, may trigger large avalanches.
There has not been an overnight freeze below tree-line for several days. Expect avalanches to be easy to trigger on steep slopes where moist snow overlies a crust. While unlikely to be large, avalanches will gain mass in gulleys and terrain traps.
This problem has been most active in the Whistler/Portal Creek area but is widespread through the forecast region. When triggered, it will be big with serious consequences. Warm and sunny conditions will increase this danger.
This problem is subject to intense periods of solar radiation. In shallow snowpack spots and sunny conditions, the danger rating will rapidly increase.
Deep facet layers remain very weak, especially in thin or rocky areas. Avoid large open slopes, steep slopes (&gt;30 degrees) and be wary that you can trigger this problem from a long distance away - the slab is stiff and it propagates far.
This problem should only exist in the afternoon near the valley bottom elevations (below 1500m), and will start once the day has warmed up and the snow at low elevations turns to slush. Ice climbers should avoid low elevation gullies.

At ridgecrests and on lee features, pockets of windslab are hidden by 10-20cm of powder. These wind slabs may be triggered by skiers and snowboarders.
A crust buried up to 1m deep may become increasingly reactive over the weekend and be hard to predict. Test results show variability: in some areas it is unreactive and in others it may be triggered by light loads (you!) and produce large avalanches.
The concern is mainly for steep, shallow terrain where faceting is likely above the crust.&nbsp;
Forecast snow and wind might make a crust buried up to 1m deep more reactive and unpredictable. Test results show variability: in some areas it is unreactive and in others it may be triggered by light loads (you!) and produce large avalanches.

Pockets of windslab at ridgecrests and on lee features are buried under low density snow and may be hard to identify.
Open lee features have new and possibly very reactive windslabs. Avoid traveling through these features.
Moderate winds and significant snowfall should be creating sensitive storm slabs in the alpine and open areas at treeline.
20cm of storm snow so far with another 10cm expected by Sunday. This is in addition to the 20cm of soft snow on the old snow surface. Loose snow avalanches can be expected in steeper terrain.
Storm snow loading on top of the persistent slab/Nov crust could make this deep slab more reactive. Field tests so far show variability with areas that are unreactive and others where light loads may trigger slides on this layer.
Open lee slopes featuring new and possibly very reactive wind-slabs. Best to avoid traveling through these features.
Fresh windslab has formed with reports of cracking, whumphing and remote triggering possible in surface layers at and above treeline. Human triggering is occurring. Loose dry sluffing will also be an issue to contend with.
Newly formed storm slabs should be treated as susceptible to human triggering. Once triggered it may overload the Nov 13 crust layer resulting in large avalanches.
Upwards of 60cm of loose dry snow has fallen. Sluff management will be essential for safe travel. Watch for others above and below you. Sluffs may overload storm and windslabs given the right location.

This problem is unlikely to disappear. It can be triggered by large loads like cornice fall or windslab failure. Human triggering is most likely from shallow spots or on steep unsupported slopes.
The snowpack throughout the region has a weak base and remains suspect. Approach all avalanche terrain with suspicion and exercise conservative route choices. This problem will persist for the foreseeable future.
The snowpack is stabilizing after the last avalanche cycle, and now we are left with a low probability, high consequence problem. Natural avalanches have mostly ceased, but triggering is still possible - especially from large loads like cornices.
SW winds continue to redistribute snow onto alpine lee slopes forming soft slab. Look for soft slab in the immediate lee of ridges and crossloaded features. Light surface wind effect is widespread above treeline.
This problem is unlikely to disappear. It can be triggered by large loads like cornice fall or wind-slab avalanche. Human triggering is most likely from shallow spots or on steep unsupported slopes.
Expect fresh slab development with snow and wind forecast for Friday.
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.
Wet snow flows like water in gullies during warm spring days, and the next few days we expect wet snow avalanches to be common in gully areas at and below treeline. Ice climbers - avoid steep low elevation gullies.
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.
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.

Soft slabs overlie a series of strong crusts in most areas. As freezing levels rise this slab is expected to be increasingly reactive. These slabs will be deepest in areas that have been wind-loaded.
At treeline and below, rain is saturating the snow that overlies a series of crusts. This wet snow will be easily triggered, is expected to run far on the crust and even if small, wet avalanches are powerful.
Friday will be warm and 7-10mm of rain below 2200m. This has potential to initiate the loose wet avalanche problem especially around steep and rocky areas. Caution is warranted for ice climbers in gully terrain.

20cm of moist snow overlies a crust everywhere other than high elevation N'ly aspects. Winds have been shifting directions and will have formed deeper pockets on lee slopes. Rising freezing levels and continued loading will make them more reactive.
Cornices dropping and smaller avalanches have recently triggered deep, persistent weak layers. The resulting avalanches have been observed to run well into the valley bottoms. With continued loading during the storm likelihood will increase.
At treeline and below, rain has saturated the snow that overlies a series of crusts. Warm overnight temps are keeping the snow weak. This wet snow will be easily triggered and will run far on the crust. Even if small, wet avalanches are powerful.

Recent storm snow and potential for solar radiation tomorrow may induce loose wet avalanches on SE through W aspects tomorrow at treeline and below.
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.
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.
Another 5-10cm of snow is forecast for Tuesday so we expect to see sluffing out of steep alpine and tree line terrain as this new snow arrives. We may also see a few small wind slabs near ridge crests so enter lee loaded terrain with caution.
The snowpack is slowly gaining strength however the basal facets remain a concern in thin snowpack areas and large triggers could create big avalanches on these facets.  Use caution in steep terrain and avoid thin snowpack areas when possible. 
Another 10-15cm of snow is forecast on Tuesday. If this arrives we expect to see sluffing steep alpine and tree line terrain, and possibly some isolated wind slabs in immediate lee areas of the alpine. Use caution if entering lee loaded areas.

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.

Fresh wind slab development will continue through the night and day on Thursday in lee and cross-loaded terrain. Be wary of these slabs immediately below ridge-crests and on exposed terrain between pitches of ice climbs.
The winds started to kick in this afternoon. Slabs will build quickly with the amount of available snow. Expect them to reach further down from ridge crests than we have been used to.
There has been heavy wind loading in most alpine areas. Expect dense windslabs in any area that has managed to hold snow. These are easy to trigger and will run far. Treeline has a similar issue, but the slabs will be less dense.
Wind slabs are found on lee and cross-loaded features. Further slab development will occur through the night due to an intense storm that is moving through.
Wind slabs are found on lee and cross-loaded features. Further slab development will occur through the night due to an intense storm that is moving through.
Intense transport has continued to build the wind slabs. These slabs are reactive on the Oct 31 crust as well as older snow interfaces. Re-loading should be a concern. Expect to come upon these slabs suddenly as you approach upper treeline.
Recent windslabs are now beginning to fail down 30-50cm on the Halloween crust.  in some areas they are stepping down to the october 17th crust.
Loose wet slides will likely occur with the rain forecast over the next 24hrs. On Wednesday we saw a few loose wet slides triggerring slabs on underying slopes in alpine areas.

We know there's a crust buried approx. 40cm below the surface, but don't know much about how likely avalanches are on it. Once there's a new thick crust on the surface, this lower layer may become less of a problem. Until then, assume it's a player.
Recent rain and warm temperatures may lead to ongoing loose wet avalanches, particularly if the snow surface has not hardened into a crust.
Rain has soaked the snowpack to ground at treeline and below treeline elevations. It may be possible to trigger point releases in steep or unsupported features.
New snow has fallen with moderate to strong winds. Wind slabs are expected in lee terrain features.
Rain and snow have loaded the snowpack. A person or machine could trigger an avalanche in areas where a weak layer remains intact, particularly where the snowpack is thin.
Recent rain at most elevations combined with overnight cooling Thursday night will reduce the likelihood of triggering this layer. Areas in which the snowpack above this layer remained dry should be treated with increased caution.
Touchy new storm slabs have been forming on the surface as rain transitioned to snow over the course of the storm. The most recent and most rapid loading has occurred in the south of the region.
Continued potential for loose wet avalanches exists where the surface has been saturated with rain and at lower elevations where new snow is moist.
Rain has saturated the upper snowpack and potential for loose wet avalanching exists on steep, unsupported terrain features. Even a small loose wet avalanche can become a big problem if it gathers enough mass or exposes you to a terrain trap.

Recent stormy weather has been building touchy storm slabs. The problem is widespread but you can expect slabs to be especially reactive in wind affected areas with more variable snow distribution
A crust that formed in October exists near the base of the snowpack and a layer of weak, sugary snow has developed above it. This layer may react to a heavy trigger such as a storm slab release. This would produce a very large, destructive avalanche.
