I have a hunch that all the precip will fall as rain, right to mountain top. Watch for the odd loose wet avalanche as the rain and warm temps break down the crust.
If precipitation falls as snow at upper elevations, a touchy, albeit thin, storm slab will likely begin to develop on top of the melt freeze crust. Avoid terrain traps and be sure to regroup in safe spots.

New snow and warm temperatures are currently 'testing' buried persistent weak layers. This layer ranges from 40-80cm in depth and is highly variable in reactivity across the forecast region with hot spots including the southern end of White Pass.
Strong southwest winds over the past week have created deep wind slabs in lee terrain features. Where these deep slabs overlie buried persistent weak layers, there is a chance for large, destructive avalanches.
Snowpack is settling and strengthening and the 0211 layer is slowly gaining strength.  At treeline this layer is down 70-100cm while in the alpine its down anywhere from 40cm to 150cm.  Sudden planar sheers are still being observed.
Wind slabs are widespread on lee aspects in alpine areas and isolated areas at treeline.&nbsp; These problems may step down to the 0211 layer so use caution.
Dynamic conditions are changing with elevation and throughout the day, due to&nbsp; warming, sun-exposure, snow flurries, and wind. Old storm (persistent) slabs lurk on sheltered low-elevation slopes, while fresh slabs may form on exposed lee slopes.

This layer is very unpredictable and still producing large, destructive avalanches. Avoid making assumptions about this layer based on the presence of aggressive sled and ski tracks on adjacent slopes.
These slabs are very soft at the moment, but that will change with the expected wind overnight. Immediate lee areas are concerning at the moment, but as the winds increase these slabs may also develop well below ridge lines.
We have seen enough activity on this layer recently to keep it as a major concern in bigger terrain. Thin coverage areas are a likely trigger point, as are large triggers (ie cornice).
This layer is sandwiched between the new storm slabs and the Feb 10th. Not a lot of action with these windslabs lately, but the potential is still there. Steep rolls at treeline are a likely area to find them.
Forecast new snow and wind should start to develop a new storm slab during the day. The added load of new snow may result in avalanches releasing below the 15-20 cm of recent snow, or below the old storm slab.
The recent snow has added a new load above the deeply buried weak layers. Cornice falls or storm slab avalanches in motion may trigger the persistent weak layers resulting in very large avalanches.

Recent warming has created a more cohesive slab over the November rain crust. Stability tests today indicate that human-triggering is likely.
Wind slabs are prominent in the Alpine and open areas at Treeline. These slabs could step down to the deep persistent slab causing a large avalanche.
Forecast wind combined with new snow or rain may result in a touchy storm slab. Watch for conditions changing with elevation.
Warming combined with increased loading from new snow or rain may increase the deeply buried slabs sensitivity to human triggers. Watch for thin spots around boulders or small trees that may be easy to trigger and then propagate to deeper areas.
Slabs are sitting on a weak basal combination of facets overtop of the November rain crust. Wide propagations and more sensitive triggering are now possible due to the recent increase in slab density.

Avalanche activity has already begun in some parts of the region as storm snow builds up over a touchy weak layer. Winds are likely to concentrate slabs on lee slopes in wind-exposed areas.
The new storm slab continues to develop. Snowfalls have been lower than forecast resulting in less avalanche activity than expected. Strong winds have transported snow into windslabs at higher elevations.
Snow and wind on Saturday night will add to the destructive potential of a touchy storm slab. Pay close attention to how much snow fell in your area, and avoid steep, wind-exposed terrain.
The new storm slab is expected to continue to develop at higher elevations where precipitation continues to fall as snow.
Rain on snow may occur as the freezing levels rise resulting in loose wet snow releasing from steep terrain features at lower elevations.
Steady snowfall, wind and rising temperatures are expected to create a punchy storm slab which overlies recently buried weak layers. Pay close attention to how much recent snowfall has accumulated in your area, and stick to conservative terrain.
Storm slabs are expected to continue to develop with forecast wind and new snow. Wind transported snow may be deep and not bonding well to the old surface.
Storm slabs continue to develop with new snow and strong winds developing pockets of deep snow on lee terrain features.

Expect wet avalanche activity in all steep terrain below treeline. Beware of gaping glide cracks.
Weaknesses could exist within or under the new storm snow. Expect deep and dense wind slabs to form in exposed NW-NE facing terrain.
It will probably be pretty wet at lower elevations (below ~ 1500m). Steer clear of slopes with open glide cracks and terrain traps.

New snow, strong winds, and rising freezing levels will form widespread new storm instabilities at all elevations.&nbsp; This problem is coupled with the preserved surface hoar layer down 20-30cm which is expected to become overloaded by this storm.
Touchy surface hoar down 20-30cm is well preserved throughout the region and has likely not seen critical loading in most areas.&nbsp; This storm is expected to produce widespread activity on this layer.
The mid-Dec weak layer is still producing large avalanches. With the extra storm loading, natural avalanches are expected to step down to this layer resulting in very large avalanches.
New snow or rain with high winds and warm temperatures will release avalanches from sufficiently steep terrain in a number of places.
A weak layer comprising of feathery surface hoar crystals and on south aspects a crust is buried between 40 and 60 cm below the surface. This layer was active during the last storm cycle and is likely to respond again to additional loading.

This layer is proving to be spotty. Parties have reported large settlements in some areas, but nothing in others. Be diligent in looking for it as it may be a significant concern.
There is ongoing faceting above and below this crust. This makes for a touchy and somewhat unpredictable avalanche problem.
We have a series of windslabs that are generally well bonded to each other, but they are sitting on the Jan 16th surface hoar. To keep it tricky, the surface hoar layer appears to be spotty and hard to find. Assume it is there and dig to find/assess.
Upper treeline is where this is more of a concern. Steep, unsupported terrain is suspicious at the moment.
This is still on our radar. Especially with today's avalanche observation. Probing will give a good indication of this layer's location and quality.
Sun and warming may increase the chances of triggering this beast, with high consequences. Sporadic deep releases over the last week are evidence that this problem is lingering.
Continue to give wind-loaded slopes a wide berth. These may look fat, smooth or bulbous, or be overhung with cornices. A wind slab or cornice fall could trigger a deeper weak layer.
Steep sunny slopes may burst into life on Sunday with a round of natural loose wet activity. A loose snow avalanche may trigger a deeper weak layer.
Warming temperatures can increase the reactivity of persistent slabs and storm slabs, which overlie a touchy weak layer of buried surface hoar.

This problem can be divided into two categories. The first will be new windslabs, and the second will be the buried windslabs that compose the upper third of the snowpack. The new windslabs will be more concerning as the hardslab interface is poor.
Upper treeline is the likely place to find this problem. Very steep (40 degree+) terrain with variable coverage should be treated with caution.
The basal layers are still considered a weak link in the snowpack. It is becoming less of a problem as the slabs above it tighten up, but in the right terrain it is still possible to trigger it. Potential large triggers should also be assessed.

Significant snowfall and extreme winds are expected to drive a large natural avalanche cycle that will likely last through Saturday. Probably best to stay out of avalanche terrain while the storm is raging.
This storm system should be a good test for the more deeply buried weak layers. With up to a meter of new snow expected in the alpine by Saturday afternoon, I wouldn't be surprised to see storm slabs step down to one of the persistent weaknesses.
New snow will add to the existing 20-30 cm of recent storm snow which is likely settling into a slab.&nbsp; Strong to extreme SW winds should form large wind slabs in everything but the most sheltered terrain.

Snowfall should taper before dawn Saturday morning, but suspect there is still potential for natural avalanche activity Saturday as the snowpack adjusts to the around a meter of storm snow.  Choose well supported mellow terrain.
There's a lot of uncertainty surrounding the deeply buried weak layers in the snowpack.  This weekend I would make decisions based on the assumption that every slope above treeline has the potential to produce a very large and destructive avalanche.

Cracking and whumpfing was being observed on Saturday in open wind affected areas.&nbsp;
New windslabs are building in Alpine terrain and open areas at treeline.
A few avalanches recently stepped down to this interface (the November rain crust) causing larger avalanches.
Heavy rain and forecast warm temperatures will promote ongoing loose wet avalanche activity. Loose wet avalanches can be pushy and entrain mass quickly. Use extra caution in steep gullies.
The snowpack is rain-soaked and weak. This increases the likelihood of avalanches failing on deeply buried persistent weak crystals which formed in December. Although less likely, avalanches at this interface would be destructive in nature.

Typically storm slabs bond fairly quick. These slabs are expected to take a bit more time due to the heavy nature of the new snow and the underlying surfaces. Below treeline, these slabs are more of a settlement slab concern instead of windslab.
The older slabs are still there and suspect. Again, the poor bond to the Jan 31st crust/surface hoar is to blame. Steep areas are concerning right now.
More of a concern with large triggers. Avalanches, cornices, rockfall are all potential triggers. Avoid exposure to&nbsp; big terrain until this layer adjusts to the new load.

While warm temperatures should help the snowpack to settle and stabilize this week it's important to remain sceptical of alpine stability.&nbsp; Upper elevations saw strong SW winds and as much as a meter of new snow which likely created very large slabs.
It doesn't look like there will be an overnight refreeze below 1500m for the foreseeable future.&nbsp; While it's probably mostly slop below treeline, remain cautious of terrain traps where loose snow avalanches could be a concern.

Recent storm snow up to 60cm deep is not bonding well at the Jan 31st interface at Treeline and above. This interface is highly variable across the forecast region. Whumpfing is common indicating that remote triggering is possible.
Recently developed wind slabs in open areas at Treeline and in the Alpine are sensitive to triggering as indicated by ski cutting results today. These wind slabs could initiate a larger avalanche by steeping down to more deeply buried weaknesses.
Large loads, such as cornices, could trigger full depth avalanches. Several very large avalanches have occurred in recent days that involved the entire winter's snowpack.

In the Alpine and open areas at Treeline there is still a wind slab of concern with the failure plane down 60 to 90cm. Watch for this problem in steeper terrain at higher elevations.
Recent snow and winds, including some &quot;reverse wind loading&quot; from Northerly winds, have created storm slabs 20 to 30cm thick. These slabs are sensitive to human triggering and some natural activity up to size 2.0 occurred on steep SW aspects today.
Weak basal layers are prominent throughout the forecast area. While the probability of triggering the basal layers is less likely, the consequences are large.
Gusty northwest winds are expected to redistribute recent accumulations into fresh wind slabs in higher elevation terrain. Due to the anomalous wind pattern, wind slabs may be found in unsuspecting locations.

Warming temperatures Monday afternoon may increase the likelihood of triggering thin soft wind slabs that likely formed on south aspects over the last few days.
Thin fresh wind slabs may be found in unusual locations.  Potentially warm alpine temperatures Monday afternoon may increase the likelihood of human triggering.
The post Jan 31st slabs have been reclassified as a persistent problem. Steep areas below ridge crests are a likely place to encounter this issue. The slabs are generally thick, and hard. Its unlikely to hit one, but it will be big if it happens.
These slabs area relatively easy to spot and predict. Open slopes at treeline is where these slabs start to appear.
As our snowpack slowly grows it becomes easy to forget about the bottom layers. Remember that the bottom is still weak in many places and requires a deep snowpack to safely bridge the bottom layers.
Wind slabs may be lurking on lee and cross-loaded terrain at and above treeline, and in glacial drainages from downslope winds.

While not particularly volatile at this time, hard slabs demand respect, especially when they rest on a crust.&nbsp; Follow the continental travel mantra of using well supported ridges and rib features as you move in the mountains this week.
Steep, convex terrain near ridge crests still pose a concern. Investigate bigger terrain carefully before committing.
Large triggers have recently impacted this layer in variable depth terrain. Watch for a weak snowpack in alpine areas and anticipate where the thin areas might be. Probing is a valuable tool to figure out snow depth trends.
Thin, old, hard wind slabs may be lurking on lee and cross-loaded terrain at and above treeline, and fresher ones in glacial drainages from recent downslope winds. Cornices are also large, undermined, and weak, and could be strained by rapid cooling.

0 to 15cm of snow is expected Tuesday night.  Any snow that falls will likely be formed into thin sensitive wind slabs by strong NW winds.
The cooler temps are helping to lock these slabs in place. We are becoming more comfortable with them, but still think there is a chance of setting them off in steep(40 degree +), crossloaded terrain.
The ground cover and elevation seem to be a factor here. This layer is much more prominent in high rocky terrain, where the depth hoar is more persistent and slow to change. Assess these transitional zones and watch for trends as you travel.

The cold has really helped this layer lock in place. It is still worth some thought as to what the consequences of your given terrain may be if it were to avalanche. Steep, unsupported terrain demands some respect still.
Some recent cornice triggered avalanches show us that big triggers can easily hit the deeper layers and cause a slide. Be to sure to assess overhead terrain from a potential triggering perspective
This problem presents as a layer of depth hoar at the base of the snowpack. To get this going we need either a large trigger or to hit the shallow &quot;sweet spot&quot; while skiing. Steep, shallow areas with a hard slab on top should be treated with caution.
Recent northerly winds may have created fresh wind slabs in south facing terrain, while older and harder wind slabs likely still exist on North and East facing slopes.&nbsp;

The weak basal layers are still prominent in the forecast area. The probability of triggering this deep weakness is low, but the resulting avalanches could be very large. Large triggers such as cornices could trigger this weakness.
An isolated and relatively small problem, but watch for pockets of fresh wind slabs in exposed lee terrain and cross-loaded gullies.&nbsp;
The probability of triggering this basal weakness is low, but if the trigger is large enough such as a cornice, the resulting avalanche will be quite large.
Keep and eye out for these as you approach open areas at treeline and above. These are not widespread but constant vigilance should be used, particularly in steeper terrain.
Forecast new snow and moderate northerly winds could combine to create fresh wind slabs in exposed lee terrain. The new snow could also sluff off as loose dry avalanches in steep sheltered terrain.

There's still uncertainty regarding how much snow we could see on Monday. I'm hedging my bets on light snow and moderate northerly winds, which could combine to produce fresh wind slabs in exposed lee terrain.
The storm slabs are currently 10cm thick at upper treeline and alpine. If the snow continues, or the wind picks up these will grow and become something to watch for. They are limited to immediate lees at the moment.
This layer still lingers in shallow areas. As the midpack facets more and more, it will lose its bridging properties making it easier to trigger the deeper layers. Watch for this situation in thin snowpack areas especially.

Light new snow combined with moderate (variable) winds have created pockets of thin wind slab in the immediate lee of ridge crests and terrain features.
Windslabs exist on lee features in the alpine. The distribution of these windslabs at treeline varies so approach open features at this elevation with caution
This may be more of a concern at treeline where windslabs have become softer due to facetting.
It will take a significant trigger, or a shallow spot to initiate the deeper layers right now. Watch snow depths as you travel and stick to the deeper areas. Especially as you enter your line.
Incoming snow and wind are likely to build slabs which could be triggered naturally, or by the weight of a person. These may include stiff wind slabs lee to the SW, and storm slabs on other aspects.

Not much change for the time being, be on the lookout for thin windslabs
There was one new report of a size one skier-triggered wind slab on a steep convex roll on Wednesday. Neighbouring regions also experienced widespread dry loose sluffing in steep terrain, and isolated small wind slab activity in exposed areas.
Light to moderate snow accumulations and strong southwest winds have built reactive new wind slabs in lee terrain. Watch for triggering in the lee of ridges and terrain breaks.
Recent snowfall and strong southwest winds have built reactive new storm slabs. The new snow, which is likely to be most reactive in wind-exposed terrain, may remain touchy for some time due to underlying weak layers.
New snowfall and ongoing strong winds have created thin wind slabs in leeward terrain features.
A weak crust/facet layer may exist down 40-60cm and should remain on your radar. A small avalanche in motion or a cornice failure may initiate an avalanche on this layer.
With the forecasted mild temps in the alpine, be aware of the strong effect of the sun this time of year should it appear. Large triggers such as cornices will weaken and could trigger this basal weakness.

New snow and wind on Monday night will create new storm slabs, but it will also add stress to a potentially touchy surface hoar layer buried up to 60cm below the surface. Large avalanches may remain a concern for days after the storm has ended.
Up to 10cm of new snow and strong to extreme southwest winds should form reactive new wind slabs on a variety of lee and cross-loaded slopes in exposed areas.
As the snowpack is subjected to ongoing significant warmth, the bond that loose snow, fresh wind slabs and small storm slabs have with the underlying crust could continue to decay. Potentially large wet avalanches remain possible Tuesday.

Looks like one more day of very warm temps. Watch for small loose wet avalanches and be aware that the large visor like cornices that overhang many ridge-tops are currently prone to failure.
As the snowpack is subjected to yet another day of significant warmth, the bond that fresh wind/storm slabs have with the underlying saturated snow and deeper crust could rapidly decay. Potentially large wet slabs may still be possible Tuesday.
Small loose wet avalanches may start to run as the freezing level rises to 1200m Wednesday.
Cooler temps and cloudy skies on Wednesday should lead to a dramatic reduction in loose wet avalanches when compared to recent days. However, when the sun shines it is intense, so be aware of rapid changes especially on solar aspects.
Triggering of the weak basal layers is still a possibility, especially in steep and shallow snowpack features.
Recent snowfall with strong winds has formed touchy storm slabs at higher elevations, especially in wind loaded areas. These slabs may overlie a weak crust layer.

Redistribution of storm snow has turned storm slabs into wind slabs in lee terrain on all aspects at treeline and above
Recent snow profile data shows numerous crusts and faceted crust layers buried in the top 50cm of the snowpack. The last few storm cycles have added light wind slabs to the scenario. Watch for wind loading on north, northeast and northwest slopes.
A facet-crust combination from early March is now buried between 50 to 100 cm down. This persistent weak layer is the prime concern right now.&nbsp; Recent storm snow has been redistributed onto lee slopes and may present a hazard as wind slabs.
This storm slab should be bonding well with moderate temperatures and may not present a problem much longer.
With recent storm loading, the March 25th surface hoar/facets combo is now buried 50 to 70 cm from the surface and requires careful consideration.
Recent storms have left us with soft storm slabs,  great skiing in some places, potentially dangerous in others.  Take the time to examine the possible consequences to your choice of riding terrain.

Runouts  are ugly. Even small avalanches can push you into and off terrain hazards.
Dense wind slabs are common in Alpine terrain and open areas at Treeline, especially in lee and cross-loaded features. Steep terrain with shallow snowpack characteristics are potential trigger points.
Storm slabs are developing with each pulse of wind and snow that moves across the region. Areas with enough snow to ride, may be the most likely place for developing storm slabs.
Heavy precipitation and strong winds are forecast to continue to develop storm slabs on all aspects. Storm slabs may not bond well to old surfaces, and may be triggered naturally or by light additional loads.
New storm slabs continue to develop as each pulse of moisture and wind moves across the region from the southwest.

Human triggered avalanches on a layer of buried surface hoar have become less likely. However, avalanches at this interface could be destructive in nature. Dig down and test for this weakness before committing to any steep lines.
New snow and wind forecast for Monday night will form new wind slabs in the alpine and at treeline. Watch for conditions that change with elevation, and use increased caution in gullies and around ridgecrests.
At the moment, a lack of a windslab is limiting any avalanche problem below treeline. When the surface condition changes, expect the surface hoar to wake up. Be sure to re-assess as you approach treeline. Watch for stiffer slabs as you travel.
Pockets of wind slab may be found on several aspects in the alpine and at treeline due to changing wind directions and loose snow available for transport.
A weakness buried early-Dec and a rain crust from mid-Nov in the mid-pack are becoming difficult to trigger but are still a concern in isolated areas.&nbsp; Heavy triggers like cornices or avalanches stepping down could result in very large avalanches.
Some pockets of wind slab may continue to be triggered by light additional loads in the alpine and at treeline.

The storm slab problem should be settling out quickly, but I would still be wary of steep unsupported features, slopes immediately lee of ridge crest and convexities.
On Tuesday we received reports of winds redistributing loose surface snow and forming new wind slabs in lee terrain at treeline and in the alpine. Watch for triggering in the lee of ridge crests and in gullies.
New storm slabs are expected to develop overnight. Storm slabs may be sitting on a weak layer of surface. Pockets of old wind slab may continue to linger at higher elevations.
The likelihood of triggering the early December surface hoar has been decreasing due to the variable distribution of this layer. However the consequences of triggering remain high.
Some pockets of windslab may continue to be found at higher elevations where winds have transported available snow.
Some pockets of windslab may continue to be triggered by light additional loads in the alpine and at treeline.
Thin wind slabs are expected to develop in response to forecast new snow and winds. These will be mostly likely found on the lee (downwind) side of steep ridge lines and summits.
Wind slabs exist in exposed lee (downwind) terrain. They may be especially unstable if they lie above the slippery rain crust that formed during the rain event that occurred at the end of last week.
Wind slabs exist in exposed lee (downwind) terrain. They may be especially unstable if they lie above the slippery rain crust that formed during the rain event that occurred at the end of last week.
Watch for soft storm snow slabs in cross loaded and lee loaded areas.
This problem is in wind prone areas below treeline and the upper reaches of treeline that are exposed to stronger, alpine winds. The slab density above the Dec4th layer will be a factor for avalanche potential. Stiffer slabs are more of a problem.
Incremental loading of a few cm per day with strong winds is expected to develop new wind slabs in the alpine and at treeline.
New storm slabs are expected to develop with forecast new snow and wind. Winds may transport snow into deep pockets on lee aspects.
New storm slabs are expected to develop with forecast new snow and wind. Watch for reverse loading as the wind direction changes back to the south.
New storm slabs are expected to develop with forecast new snow and wind.
New storm slabs were delayed as the storm did not push inland as fast as forecast. Strong winds and new snow should develop storm slabs overnight.
Loading from wind and new snow continues above the early December surface hoar. This layers distribution varies across the region.&nbsp;
Watch for the development of soft slabs especially in lee features. The new snow may be falling on a layer of surface hoar in sheltered areas bellow tree-line resulting in surprisingly touchy conditions.
1681A555">Wind slabs are expected to develop at tree-line and in the alpine as the wind picks up through the day.
Storm snow is likely to slide readily on steep terrain, initially in relatively small avalanches. The expected size of avalanche will increase in areas where significant wind drifting occurs.
As snow accumulates during the storm, steep terrain will become susceptible to avalanche activity, especially where the wind has drifted snow into dense pillows.

We have multiple layers of windslabs in the alpine and upper treeline. Below large alpine cliffs is a small, but reactive slab forming from spindrift. The older windslabs are still present on N-SE aspects.
New storm slabs have developed in the alpine and at treeline. Pockets of wind transported snow may be deep due to strong winds during the storm.
Areas with buried surface hoar down around 100 cm may continue to be triggered by light loads in weak spots around exposed rocks or trees. This layer of buried surface hoar is variable across the region.
Wind direction is variable across the region. Mostly southwest in the south of the region under the influence of Pacific storms, and northeast in the north where the arctic ridge is holding strong and keeping temperatures low.
New soft slabs may be easy to trigger or release naturally. Storm slabs may increase in size as the slab consolidates and may be sitting on a sliding layer of buried surface hoar.
New storm slabs may not bond well to the old surface of cold loose snow, wind crusts, and/or buried surface hoar.
Loose snow may slide easily on buried wind crust and or surface hoar.
="s_3FE45715">The combination of heavy snowfall and strong SW is expected to result in widespread storm slab development. The slabs will likely be human trigger-able Saturday afternoon. Stiffening wind slabs are expected in wind exposed terrain features too.
New snow and wind on Friday likely developed soft storm slabs, especially in lee features. The new snow may have fallen on a layer of surface hoar in sheltered areas bellow tree-line resulting in surprisingly touchy conditions.
Friday's storm was still generating locally heavy snowfall and moderate to strong SW winds late Friday evening. Fresh wind slabs will likely be sensitive to rider triggering in wind exposed areas through the weekend.

Fresh windslabs are building in immediate lees along ridgelines and in crossloaded features in Alpine terrain.  These slabs are more isolated in treeline features.
New snow will add to the existing storm slabs. Strong winds at higher elevations are expected to create deep pockets of wind transported snow. Cold temperatures may limit slab development.
New cornice growth may be weak and fall off naturally or be triggered by continued loading from new snow and wind.
Strong SW wind and up to 55cm of new snow are expected Saturday night. This combination is expected to produce storm slabs that will likely remain sensitive to human triggering all day Sunday.
Forecast new snow and wind will add to the existing storm slabs. Deep pockets of wind transported snow are expected in the alpine.
New cornice growth may be extensive and not well bonded to existing cornices. Stay well back from corniced ridges.
Thin new windslabs may continue to develop with each snow and wind event. Watch for old buried windslabs that may now be exposed to new winds or reverse loading.
Wind affected slabs are likely near ridge lines and features. Soft slabs are possible from sheltered start zones.
Storm slabs continue to develop with each pulse of new snow and wind. Cool temperatures may be limiting slab development.
No new reports of avalanches on this weak layer. Watch for continued loading above this weak layer at and near treeline. Low likelihood, but high consequence if you trigger this buried surface hoar.
Even if new snow amounts are modest in your riding area, there's plenty of loose snow on the ground for redistribution by forecast strong winds on Sunday. Watch for new wind slab development at treeline and in the alpine.

We're in for a strong dose of SW wind Sunday and there's plenty of snow available to form fresh wind slabs. Wind sheltered terrain at and below treeline may harbour a storm slab up to 30cm in depth that rests on potentially touchy surface hoar.
Fresh wind slabs are building in immediate lees along ridge-lines and in cross-loaded features in Alpine terrain and just into Treeline. These slabs are sensitive to human triggering in steeper terrain and in convex and unsupported features.
Storm slabs may be deep at higher elevations where they have been transported by the wind into deep pockets. Watch for slabs developing at all elevations if the storm snow settles and becomes more cohesive.
New cornice growth may be weak and fall off naturally or be triggered by continued loading from new snow and wind.
New storm slabs continue to develop with each new load of snow and wind transported snow.

Low-density powder may be hiding wind slabs which formed during stormy weather on the weekend. They may have gained considerable strength, but I'd remain cautious on high-elevation lee slopes. Loose dry avalanches are also possible in steep terrain.
Gaining strength in the alpine but previously soft unconsolidated layers at tree line elevation have since formed a soft slab over an underlying layer of surface hoar.

Rising freezing levels in the next 2 days may make this problem worse.

Wind slabs are still lurking on lee slopes at treeline and above.&nbsp; A wind slab might provide enough force to trigger weak layers buried deeper in the snowpack
Recent cornice failures have triggered this storm slab, a loose wet or dry avalanche might provide enough force to trigger this slab.
Cornices are large and fragile, and with the warm temperatures may be easily triggered.
Wind slabs are still lurking at tree line and above.
Cornices are becoming large and fragile with warming temperatures. A cornice failure might trigger deeply burried instabilities and produce a large and destructive avalanche.
Wind slabs exist on many slopes. It may still be possible to trigger these with the weight of a person or snowmobile.
Any slopes receiving direct sun may weaken and start to spill loose wet avalanches.

Incoming snow, wind and rising temperatures may create a new storm slab problem. Recently formed wind slabs are also lurking on many alpine and treeline slopes.
Rising freezing levels may bring rain and lead to loose wet avalanches. These can gather a lot of mass and push you around.
A storm slab or wet avalanche could step down and trigger a deeply buried weak layer, creating a surprisingly large avalanche.
A weak layer of surface hoar and/or a crust down 60-100cm remains susceptible to large triggers such as cornice falls or smaller avalanches stepping down. Wide fracture propagations are likely.
Lingering storm problems remain sensitive to human and solar triggering.  This includes storm slabs over a layer of surface hoar in deep snowfall areas, old wind slabs in the alpine, and sluffing from steep sun exposed slopes during the afternoon.
Large and fragile cornices are will likely continue to fall of ridge crests with sun exposure and temperature fluctuations. Not only are they a hazard in themselves, but also a heavy trigger for slabs on the slope below.
A weak layer of surface hoar and/or crust down 40-70cm is susceptible to large triggers such as cornice falls or smaller avalanches stepping down. Wide fracture propagations are likely.
A weak layer of surface hoar and/or a crust down 70-90cm remains susceptible to large triggers such as cornice falls or smaller avalanches stepping down. Wide fracture propagations are likely.
The expected strong solar input tomorrow may increase the likelihood of triggering. Steep south slopes and overhead slopes, should be treated with caution later in the day.
Recent avalanche activity has tested this layer with encouraging results. Despite that, we must recognize the variable nature of the snowpack and still treat this layer with some concern. Big terrain should be approached with caution.
A weak layer of surface hoar and/or a crust down 50-90cm remains susceptible to large triggers such as cornice falls or smaller avalanches stepping down. It may be still be possible to directly trigger this layer during the heat of the day.

Be alert for lurking wind slabs in lee terrain at treeline and above.
Cornice growth continues.&nbsp; Use caution around, under, and near cornices.

Reactive wind slab slabs may still be found in high, north east facing terrain
The slab overlying the mid-Feb melt freeze crust varies from 40 to 100cm through the region. This is still a layer to keep in mind, as an avalanche on this layer could be large and destructive.
Cornices are large and fragile in the region. Daytime warming with high freezing levels will only make them more prone to collapse.

It's still a good idea to watch out for wind slabs, especially on high north east aspects.&nbsp; Triggering a wind slab might produce enough shock to wake up deeply buried instabilities.
The storm slab seems to be bonding well to the Feb. crust interface in most parts of the region.&nbsp; It may still be reactive on solar aspects during daytime heating, and on high NE aspects where it may have facets associated with it.
Rising freezing levels and strong solar input can make large cornices weak, use great caution in areas that may be affected by potential cornice failure.
Wet surface snow may re reactive on solar aspects in the afternoon with forecast warm temperatures and strong solar radiation.
Wind slabs exist on many slopes. It may still be possible to trigger these with the weight of a person or snowmobile.

Thin new wind slabs may form with moderate SW winds overnight. An underlying sun crust or surface hoar layer may increase the reactivity of these slabs.
The likelihood of triggering the weak crust/surface hoar layer down 50-90cm is decreasing with colder temperatures. In the Monashees, a patchy layer of surface hoar down 30-40cm may still be reactive to skier triggering.
