Tightening up with cold. Only very isolated pockets left by now. Hard to trigger.
Hard to trigger in the cold. likely quite isolated. maybe some x-loading with change in flow.
This is sitting on a crust that was buried wet. I think snow on top was only 15cm deep so with the cold weather there may be some facetting happening to this layer in the next few weeks.
Isolated pockets of windslab on southerly aspects from reverse loading and cross loading. Concern on 35+ degree terrain.
Light to Moderate winds from the N, NE, and E producing thin soft slabs on S, SW and W slopes. Slabs formed previously on N, and NW slopes sitting on a crust buried wet remain a question in isolated areas.Continued faceting with cold temps on this interface. May be less sitting on this now with outflow winds.
Reverse loading with Mod-Str NE, E winds continues to strip and load. Isolated HSL and SSL on W, SW, S asps. Cooler temps helping with the bond between windslabs and old sfc  in short term.
Sa 1.5 in Teddy Bear trees (GNP) with whumpfing observed prior
High uncertainty, but probably limited to upper TL or N'ly asp where FC are preserved.
Wind effect well into TL. Question as to the bond between slabs and old snow surface. Temps seem to be staying cool up there.
Sa 1.5 Teddy Bear trees a few days ago. MW Heli talking about HSL if you aren't a little careful with terrain selection.
Pretty locked in. Isolated steep unsupported features.

touchy below 1700 m. running on  5 mm P-K MFcr (091220)
Complex issue, where surface hoar may have been I would be very concerned.
HSL exist further below ridges than expected. More snow for transport. Stipped or HSL at ridge top.
Most reactive to stability tests in sheltered shaded terrain at lower elev.
In the Interior 20cm of snow covers this layer. Near Terrace near 30cm.
Very isolated distribution, widespread whumpfing in Coq Pass area yesterday, reactivity could pick up with Fx loading and warming.
Mostly a concern where a solid crust is just below the  surface
Primarily in Lizard Range. Contd reports from Fernie ski tourers of Sr-Sa 1-1.5 on steep convex rolls @TL, fast moving. Stab results indicate propagation propensity decreasing.
Mostly a concern where a solid crust is just below the  surface. It's rained so long for so hard that it's well perc'd and the precip is being peed out the bottom.
Lizard Range: 1 Vc 2.0, N asp
Elk Valley: CTE4 (SP) down 25cm
As HST accumulates there's more room for rain to disperse. Any pooling crust is now deep. Think HST is percolating.
Down 60-90cm in the Lizard and only down 30-50cm in the Elk Valley/crowsnest.
I think that treeline is still where it is at with this layer. Hard to trigger / size 2.5 consequence.

heavy rain on sunday. FZL dropping to 400m Monday 5cm snow
Widespread condition but variable distribution. Most prominent in sheltered, shaded areas. Seems more of a problem in Selkirks and Monashees, not so bad in Cariboos--yet. I am leaning to high danger for Selkirks/Monashees at the treeline elevation band even though I know that by the letter of the definition it's probably Considerable. More on my reasoning here in the snowpack discussion.
SH reactive. Variable in nature across the terrain. Did not form everywhere. Snow starting to bond to CR on south / southwest.
patchy at TL, primarily a concern inland. FC rounded out in southern Sea-to-Sky
SH is now 8 days old, 40-60cm deep, and reactive to light external loads. We are entering a time period where the SH will be twitchy through this week. Distribution appears to be localized including some south aspects, but most prevalent in sheltered areas.

Primarily in Lizard Range. Sev Sr (30-100) 2.0 on SH 4-8 mm in Tunnel Cr.
SH remaining reactive. SH most reactive on sheltered aspects. Stability tests appear to remain in the moderate range with planar fracture character.
We are still concerned about this layer (GJ / DM). In spite of indications it is settling down a bit and propagation are decreasing, I worry that perhaps we are not getting the full picture: that is, have folks identified problem areas and are now staying away from them and/or is use being concentrated in areas with compaction? Certainly that's what I'd be doing if if were out there.
Reactivity seemed to taper off for Sat then pick up again on Sunday with additional load
Fluctuating FZL during recent storms created various MFcr in HST with poor bonds
Fluctuating FZL during recent storms created various MFcr in HST with poor bonds. Snowline generally above 1600 m with moist up to 1900 m.
Lizard Range: CTN with warm temps strengthening upper snowpack

Upper TL and lower Alp yielding biggest results
091229 persists with moderate to hard SP results in Lizard range and CTE (SC) in Crowsnest Pass.
Most prominent at this elevation band. Reports and similarities with the Cariboo range and further south suggest this. Buried under 40-60cm slab.
I think that treeline is still where it is at with this layer. Hard to trigger / high consequence situation.
Wind slabs building 30 cm thick in next 24 hours below ridge crests and terrain features that funnel or accelerate the wind.
5-15 cm HN + M,S winds. Thin windslabs easily Sc to sz 1
Interior & Northern only. Think warmth in Coastal areas has bonded them.
Easily skier triggered on steep unsupported slopes this weekend. Involved surface snow only. Minimal potential to bury a traveller. Greater potential to get carried through trees/over cliff.
Prev HST must have stabilized by now. Tues precip could have potential to bury a traveller. Greater potential to get carried through trees/over cliff.

Strong SE winds formed dense wind slabs in N-W facing terrain - switching to W/SW but not much loose snow left to move. Wind pressed and dense snow at all elevations
Ski-cuts on small wind slabs produced nothing but cracking, but the potential was certainly there. Generally manageable on short steep slopes, but you wouldn’t want to be taken for a ride on the Backside.
Strong winds digging to TL will build pockets of WS.
Mod to strong NE'ly winds producing new thin wind slabs in exposed lee. Some cracking observed on Sat. Low consequence at the moment, but building through Sunday - not too much loose to move.
Isolated to solar aspects for now until it really warms up on Wednesday.
Not quite as widespread as in the alp, but strong low level winds will produce more slabs than normal.
Not quite as widespread as in the alp, but strong low level winds will produce more slabs than normal. Upside down storm and it's resting on FC, hard CR, etc.

Largely unconsolidated HST so far, but as load increases incrementally Dec 29SH will become more reactive. Buried SH on all asps except steep exposed S facing.
Wet and heavy snow. Winds probably not pushing too much around.
SH has reached critical load. Buried sc on steep solar. warm temps!
SH is now 6 days old, 50-60cm deep, and reactive to light external loads. We are entering a time period where the SH will be twitchy through this week. Distribution appears to be widespread, but most prevalent in sheltered areas.

SH reactive. Snow starting to bond to CR on south / southwest. Fatal avalanche yesterday within the BRC tenure. Private party. Limited details at this time.
Storm pattern just firing up, load will increase. Step down potential to Dec 16.
Slab property is evolving with warming and wind. 15-20mm additional load Jan 8-10. Avalanche sizes seem to be increasing up to 2.5 (Adamants). We think InfoEx is showing bias with lots of terrain avoidance / low confidence.  Widespread layer, Reactivity is patchy.
Storm pattern-load increasing. Step down potential to Dec 16.
SH may be waking up as slab develops with warming temps and winds. Avalanche sizes increasing again indicating increasing propagation.
Getting tougher to trigger but more load and warming coming
SH may be waking up as load increases and slab develops producing Na and skier triggered avalanches.

HST and increasing slab properties on this layer is making this layer one to watch.
Warm temps (and solar today) will likely promote slab development. May be triggerable in all steeper terrain.
Could become very touchy if winds materialize on Sat evening and Sunday.

15-25 deep. Snow moist to around 1700m all aspects. Crust capping the layers.
Reports from Grouse and Seymour giving Xe and Sc results respectively today in the top 10-15cms only; however, they did control work yesterday. No results going down to last weekend's crust as this system came in fairly warm and wet.
Still reactivity on this layer. Reduced probability when it goes the slab has consolidated enough that the sizes will remain large.
Strong winds, copious amounts of snow will build wind slabs.
Over 60cm of new snow is expected today and tonight.

Getting hard to trigger now that it's cold.
Hard slab, starting to become faceted in itsel
Newly formed from mod SW winds on the leading edge of  the storm.  Lee loads on exposed TL.
Fri warm temps building cohesion in sfc layers. In most places should tighten in and settle down with cooler temps. Caution for SH in sheltered glades. Two problems - where there is SH and where there isn't... the latter will disappear.
Wind picked up on Friday and started to transport snow.  Lee loads
Doen't sound like much wind effect at TL, but suspect that some slabs exist.
Slow accumulation in cool temps, no slab yet
Wind blowing Mod SW easing off tomorrow.
Fx S,SW winds but limited snow to transport due to previous reverse loading and solar warming on S asp
Soft slab building with additional load, winds and fx'd winds.
S,S-SW winds, but new snow generally moist, so not much transport.
Consistent loading pattern has let up
Watch for open TL and ridge features
Generally it's either released, bridged, adjusted to load, etc. Landmines exist with nasty potential. Starting to think thin spot triggering type story. NE mentioned moraines and similar terrain features are susceptible to the land mine theory.
Cornices at ridgetops are getting heavy, large and droopy.
No mention of this layer recently. Concern remains in thinner, complex and undisturbed (skied/ridden) areas where it may still be triggerable.
CTM (SP) down 27 on SH 3-4mm in Whistler
Power Cowboy: 2xCTH21 (SP), PST 25/100 down. Concern remains in thinner, complex and undisturbed (skied/ridden) areas where it may still be triggerable.
Wind transport is a factor only on the highest ridgetops of the forecast area (1400 and above). Below this the snow surface was rained on and subsequently froze so there it no snow available for wind transport.
Terrace/Smithers divide: 1 Na 2.5 S steeping down to 80cm, N asp 1800m. CTH (SP) down 60cm
This is likely ridge tops at higher elevations. Concern for failing cornices, but not so much as a trigger for avalanches.

TLH: 1 Sa 2.0 S 75-95cm on 100203 SH/FC 2100m NW asp. Generally CTM-H in tenure area with CTE shears in Taylor drainage.
TLH:  Generally CTM-H in tenure area with CTE shears in Taylor drainage.
TLH: Confidence growing with previous warm/moist snow setting up and bridging PWL's.
Concern for people wandering out on cornices.
Cornices are generally small, but isolated overhanging cornices exist and may crumble under warm temps.
Run far and possibly wider due to PWL grain form below.
LFH Sean F: Early Dec cold snap has left a surface hoar/factet layer now buried down @ 20-30cm. There is not much load or tension on this layer now, but should be a performer down the road.

Not deep enough yet.

SE through SW winds forming up to 15cm pencil hsl on exposed N asp Fri/Sat. Fx S,W winds but limited snow to transport due to previous reverse loading and solar warming on S asp.
Ssl in open areas at TL and above. Fzlvl to 1500m Fx with strong S winds. Step down potential to Dec 29 SH.
I think there's a band somewhere around treeline where there was rain, but not that much; there was a cycle, but not all slopes. Possible that less steep slopes didn't release and are still primed. Primarily an interior & northern problem.

Storm snow amounts should vary: 50-70cm North Shore/Howe Sound, 20-30 Whistler, 15-20 Inland.
Intense solar and warming expected this weekend. Good overnight recovery.
Sun didn't have a huge impact on Sat - NE'ly keeping it cool. Watch steep open slopes in the later afternoon.
Recent storm snow may destabilize under sunny and mild weather. Could see some solar induced slabs... or wet loose.
Cloud cover and cool temps expected to keep activity to a minimum.
Intense solar and warming expected this afternoon, after another 5-10cm new yesterday...
this layer exists but from what i can tell it's really not much of an issue. not much in the way of hard data though, other than from GNP.
Starting to be more difficult to trigger, due to the upper snowpack tightening up. Would be even more difficult to trigger in this elevation band due to the bed surface sticking through and less faceting around it.
likely only enough HST in heavy snowfall areas. Sitting on SH near Terrace
Developing into more of concern with increased stiffness due to warming temps.Really only a Selkirks Monashees issue.
Slow accumulation in cool temps, no slab yet, except where winds affected snow
New snow expected to be warm and upside down
Expect 10-25 cm HST. Covers 100108 SH. Expect cycle of small avalanches. Step down potential? Rain on snow a contributing factor. Upside down storm on a cold snowpack.
Varying temps during recent storms probably created some upside-down slabs and Jan 8th SH seems to be prevalent in Blue River area
I think there's a band somewhere around treeline where there was rain, but not that much; there was a cycle, but not all slopes. Possible that less steep slopes didn't release and are still primed.

Precip amounts have backed off a little for today but should see 30-50mm around Terrace today.
Still cool snow at higher elevations. Possible to trigger slab in isolated areas. Steep convex rolls, unsupported. Fast settling of HST instabilities.
Where a thick sun crust exists below recent storm snow, I have little concern for this layer.
On Mar 7 SH or Crust in some areas (Duffy? S. Chilcotins for sure). Amounts vary from 60-90cm HST. Trending to wet slab as the rain arrives

Continued HST on Wed/ Thurs. Total HST amounts are probably around 40-60cm - rapidly settling (Settlement cracks, 5cm ski pen,...)
Winds will be very strong from the SE initially, shifting to NW in the am. I expect it will be pretty blasted.
Forecast S-E, SW winds with new snow to transport
New snow is coming in warm in most places, so probably not a whole lot of transport at TL

Sure Bear Pass was at record low HS for most of the season. Yes LFH spent lots of time talking about "Cautionthin HS areas". Winter started around March 10. IMHO this won't be a problem until spring onion layers start to peel.
Growing cornices with the storm, greater concern on the weekend when it clears and temps rise.
Sluffing in steep terrain. Maybe more reactive with sun exposure
Uncertain whether a slab will form by tomorrow.... expect warm temps to promote settlement
Staring to slab up at lower elev in Southern part of region
Latest obs from Ninginsaw (where it's only down 23 cm) suggest this layer (SH where observed) has low propagation propensity (possibly because it's still too shallow)
Winds digging at TL will probably redistribute snow into thin Wndslabs.

A mix of rain and snow is forecast to fall Saturday. Wet heavy snow falling on an old crust has the potential to initiate a round of slow moving destructive avalanches.
If the freezing level is even slightly lower than currently forecast, the north shore mountains could receive a significant shot of snow Saturday. If snow begins falling in earnest, it's time to move out of avalanche terrain.
Rain at lower elevations will weaken the snowpack with the potential to create pushy loose wet avalanches in steep terrain. Destructive wet slab avalanches are also possible.

Moist or wet snow may become weak during periods of warm temperatures and/or due to exposure to strong solar radiation. Loose snow may fall out of steep terrain and entrain more snow in its path.
Forecast high freezing levels combined with new snow or rain may result in storm slab avalanches near ridgetops. Rain soaked slopes at lower elevations may have loose wet slides from steep terrain features.
Forecast new snow may not bond well to surface crusts at higher elevations where it has not been warm enough during the day to break these crusts down. Southwest winds may transport some new snow into pockets of wind slab.
Forecast new snow and wind may develop new storm slabs at ridgetop elevations. Rain at lower elevations may result in loose wet slides. Watch the the freezing level for the rain/snow line.

Rain on snow may occur as the freezing levels rise resulting in loose wet snow releasing from steep terrain features at lower elevations.
Snow is expected at the tail end of the storm that could build up in the lee of ridges at high elevation areas. I suspect the likelihood of triggering to remain low unless this area sees a lot more snow than expected.
Small loose dry avalanches could become a problem late in the afternoon if new snow totals exceed 10 cm.
Watch for new wind slab formation in upper elevation terrain. Terrain that has enough coverage to ride may be the only terrain where an avalanche problem exists.

The Dec 13th Crust seems to disappear around 2200m. Watch for windslabs overlying this crust in and around this elevation band
Seems to be more of a problem in treeline areas.
New snow will likely have a poor bond to the melt-freeze crust at all elevations. Sluffing and loose dry avalanches may have enough mass to push you into terrain traps.
The December rain crust is still possible to trigger down 30 to 50cm at 2200m. Recent stability tests indicate failures at this interface in the moderate range.
On Sunday, new snow and wind will create fresh slabs in lee terrain. Backcountry slopes that have accumulated enough wind-blown snow to have good riding, may be the most likely to produce avalanches.
A layer of facets over this crust is continuing to produce results in the easy to moderate range.
Southern areas near Terrace and Kitimat received ~30-45 cm of snow by Sunday afternoon. There is potential for storm slabs to form in sheltered areas, or the new snow might just react at loose dry sluffs in steep terrain.
Snowfall accumulations from Sunday are expected to be rain-soaked by Monday. Expect widespread pushy loose wet avalanches activity in steep terrain.
The lack of a windslab on top of this layer is keeping the avalanche activity limited. Watch for a change in density as you travel. This change may signal a potential windslab.

A layer of facets sits on the Dec 1th crust layer which is reactive in the moderate range down 40 to 50cm at Treeline. With the recent wind and snow load this layer has become more sensitive to triggering.
Buried persistent weakness should remain on your radar as they has the potential to produce large avalanches.&nbsp; Smaller avalanches or cornice falls have the potential to trigger a deeper weakness.
Two persistent weakness remain a concern in the mid-pack. The early-Jan and mid-Dec layers are down around 50cm and 80cm, respectively.&nbsp; Human triggering remains possible or smaller avalanches may step-down to one of these layers.
Periods of heavy snowfall could create fresh touchy storm slabs in sheltered terrain. Warming and rain could trigger wet slabs or loose wet sluffs at lower elevations.
A weak layer buried mid-December is still producing dangerous avalanches over a month after it was first buried. Particularly for slopes around treeline, there is a danger for a small avalanche to step down to this layer increasing the consequences.

Fresh snow may be sensitive to human triggers on smooth open slopes at higher elevations. It will be particularly deep and touchy on the downwind side of ridge crests and in wind-loaded gullies.
Surface hoar is considered a long term problem. Its exact location in the terrain is still a question. Be prepared to look for it as you travel. Using small terrain as &quot;tester&quot; slopes will help indicate the reactivity.
Human triggered avalanches are still possible, especially on North facing terrain at, and just below tree-line due to a layer of buried surface hoar.

Fresh snow will be sensitive to human triggers, especially on smooth open slopes at higher elevations. It will be particularly deep and touchy on the downwind side of ridge crests and in wind-loaded gullies.
A weak layer of surface hoar may be buried in the upper snowpack, although reports indicate it is spotty in its distribution across the region. Where it exists, I suspect that it may be at a critical depth for human triggered avalanches.
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.
The Dec 4th persistent weak layer, buried 50 to 70cm at Treeline, remains a concern in the snowpack, as it continues to give results in snowpack stability tests. Open slopes and convex terrain are areas with potential for human-triggering.
Heavy snowfall over the weekend created slabs 40-70cm thick.  This snow overlies heavily rain soaked snow which is capped with a crust.  Strong SW winds have formed thicker wind slab in leeward features.
The Dec 4 persistent weak layer is buried up to 70cm at Treeline and potential for human-triggering remains. This layer and it's sensitivity to triggering are highly variable. Take the time to explore the snowpack as you travel through the terrain.
Pockets of unstable storm snow may still exist on steep slopes. The most likely places are immediately behind steep ridgelines on north-facing slopes where the wind has deposited snow in wind slabs.
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.
Some pockets of wind slab may continue to be triggered by light additional loads. Thin new windslabs may develop overnight with forecast new snow and wind.
Human triggered avalanches on a layer of buried surface hoar have become unlikely. However, avalanches at this interface could be destructive in nature. Dig down and test for this weakness before committing to any steep, exposed lines at treeline.
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.
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.
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.
New storm slabs are expected to develop with forecast new snow and wind. Winds may transport snow into deep pockets on lee aspects.

We're looking down the barrel of another significant shot of new snow and wind Saturday night and Sunday which is expected to form fresh sensitive storm slabs at all elevations.  Reign the terrain choices back on Sunday.
A few buried surface hoar layers exist in the top 100cm of the snowpack. I would keep these on my radar on steep unsupported slopes, especially at treeline and below.
35cm of recent snow is likely settling into a soft storm slab at all elevations.  You may find a slightly stiffer wind slab near ridge crest. Both storm and wind slabs are expected to remain sensitive to human triggering Monday.
Weak layers within the recent storm snow may continue to produce soft slab avalanches in the top 30-40 cm. Storm slabs may become more stubborn to trigger. Deep pockets of wind transported snow may result in larger avalanches.
Recent storm snow may continue to be triggered by human activities. Cold temperatures may have slowed the settling and bonding process. Watch for forecast solar radiation to settle the storm snow into a cohesive slab over the next few days.
Cold temperatures may have slowed the settling/bonding process allowing recently formed wind slabs and ageing storm slabs to remain sensitive to human triggering.
Several weak layers of surface hoar may be buried in the top 100 cm of the snowpack. Forecast warming of the storm slab above these weak layers is a concern for increased sensitivity to triggering and the possibility of longer fracture propagations.
Pockets of wind slab may not be well bonded to the old surface. Forecast warming may increase the sensitivity of wind slabs to triggering.
This is the piece of the puzzle that won't let me drop the danger rating to LOW. The consequence of triggering a buried surface hoar weakness is high, although the likelihood of triggering seems to be getting lower.

I'm still concerned about the layer of surface hoar buried back in January.&nbsp; Could the forecast storm be the straw that breaks the camels back? I'm not sure! Given this uncertainty I would avoid open features around treeline tomorrow.
Moist or wet snow may continue to release naturally or with light additional loads until the freezing levels drop.
Watch for wet cohesionless snow in steep gullies and cliffy slopes.
Snow should accumulate throughout the day on Saturday. Fresh pockets of wind slab could form in steep open terrain if we see more than 15-20 cm with strong enough wind to move the snow around.

A concerning layer of surface hoar is buried 60-120 cm below the surface and remains to be reactive to human triggers on certain slopes. The challenge is determining which slopes, meaning steep open slopes at lower elevations should be approached with great caution.
A surface hoar layer that formed in December is now buried anywhere from 30-100 cm below the surface. Open slopes around treeline elevations are the most suspect terrain for triggering this layer.
A weak layer of surface hoar is buried 80-120 cm deep and has produced numerous human triggered avalanches over the past week. Steep open slopes at and below treeline should be approached cautiously.

A surface hoar/crust layer, down 35-80 cm has become reactive with the loading of new storm snow. This layer is most likely found in sheltered openings around treeline and below.
Above freezing temperatures and possible light rain at lower elevations may produce wet loose activity in the surface snow. These point releases are expected to be small but could have greater consequences in areas where terrain traps exist.
Buried surface hoar layers could produce persistent slab avalanches on convex rolls around treeline elevations.

Above freezing temperatures may trigger loose wet avalanches. Pinwheeling and rollerballs are good indicators of this type of instability. Avoid steep slopes with saturated snow, as wet loose avalanches can be surprisingly destructive due to their higher density.
reezing levels are expected to rise to 2500 m by the afternoon. If the warm temperatures break down the crust expect loose wet avalanches to occur, especially from steeper terrain features.
Reports suggest some slopes at treeline have a weak layer of surface hoar 30-50 cm below the surface. An avalanche cycle cleaned out this layer in many areas, but in places where avalanches have not yet run, it remains a concern. Use caution around convexities in open trees.

A weak surface hoar layer is now down ~85cm. This layer has been triggered by humans; remotely from 40m away, and capable of wide propagations up to 150m. Rapid loading or other avalanches may trigger this layer and produce very large avalanches.
Loose wet avalanches or moist storm slabs in steep terrain are likely over the next 36hours.  Until things cool down travel in avalanche terrain is not recommended.  Things should improve quickly with the cool temperatures forecast for Sunday.
A weak surface hoar layer is now down ~1m. This layer has been triggered by humans; remotely from 40m away, with propagations up to 150m wide. Rapid loading and other avalanches triggered this layer yesterday producing very large avalanches.
A weak surface hoar layer is now down ~1m. This layer has caused widespread avalanches: natural's up to size 4, and size 2.5 human triggered avalanches. In areas where it hasn't already avalanched it is very reactive, and has been remotely triggered.
A weak surface hoar layer is now down ~1m. This layer has caused widespread avalanches: natural's up to size 4, and size 2.5 human triggered avalanches. In areas where it has not already avalanched it remains touchy, and has been remotely triggered.
The Feb 12 PWL continues to be a concern. During the last storm cycle several avalanches &quot;stepped&quot; down to this layer.  It will remain a problem for some time.
The Feb 12 PWL continues to be a concern. During the last storm cycle several avalanches &quot;stepped&quot; down to this layer. It will remain a problem for some time.
Solar radiation and daytime warming will start to melt the new snow. This will create moist or wet point release avalanches on steep solar aspects at lower elevation to treeline.
Clear skies, calm winds, and a stronger, March sun will likely create unstable conditions on steep, southern aspects. This will be more of a problem at lower elevations.
Solar radiation and warm daytime temperatures will start to melt the new snow and penetrate the snowpack. This will create moist or wet point release avalanches on steep solar aspects at lower elevation to treeline.
It will likely take a large trigger, like a cornice or another avalanche to trigger the surface hoar/crust layer from February 12, now down 1-1.5m. The resulting avalanche would be very large and destructive if triggered.
It will likely take a large trigger, like a cornice or another avalanche to trigger the  Feb 12 and March 11 PWL's, now down 1-1.5m. The resulting avalanche would be very large and destructive if triggered.
With the clear skies forecast on Sunday expect activity on solar aspects as things heat up. Most of this will likely be black body starts or minor surface sluffing but if the moisture penetrates to the well developed crusts this could produce more.
Two weak layers are buried down 1-1.5m.  Though unlikely, a large trigger like a cornice or another avalanche may cause these weak layers to fail.

New snow (15cm) rests on a buried smooth temperature crust particularly on South aspects. The surface snow can quickly become wet and active with heat from the sun.
10-15 mm of rain on Wednesday will destabilize the melt freeze crust currently covering the isothermal snow below.&nbsp; Expect loose wet slides on steeper slopes and in gulley features.
Glide cracks, gaping cracks in the snowpack, exist on many slopes and have been failing with warm temps. They can fail unpredictably and release the entire snowpack to the ground.  The  overnight storm snow may provide a trigger for deep releases
Very cold temperatures from the past few days have made the upper snowpack unconsolidated and riders should expect fast sluffing on steep slopes in areas that were not wind affected.
Associated with mid pack crusts we see a layer of sugary crystals underlying stiffer upper layers. Use more caution in thin areas as triggering&nbsp; may be more likely.
The crusts near the bottom of the snowpack have been weakening, especially on cooler North aspects.
Weak snow associated with crusts formed in Mid and early November can be found down about 70cm. This seems to be less significant on Southerly aspects. Triggering planar slopes from thin areas remains a possibility to consider.
This is mainly a problem at treeline and below, West of the divide where 40-70cm of snow has fallen over the last six days. There has been less wind in these areas, and high humidity has promoted slab development over the facets.
This is mainly a problem in the main ranges where the 40-50 cm of storm snow is not yet bonded to the old snow. Shooting cracks and whumphing was observed at treeline west of the Divide as skiers attempted to access more open terrain.
There is lots of new snow plastered to steep rock and ice terrain. With the expected warming trend (and solar effect) over the next week, expect this terrain to shed this snow.

More likely areas where the slab could be triggered are in&nbsp; steep unsupported terrain.
More likely areas where the storm slab could be triggered are in steep unsupported terrain.
Large sluffs can be expected in steep terrain. They are likely to gain mass and move quickly. Take extra care above and below terrain traps.
The new snow now has enough cohesion in some locations to act as a soft slab on steeper features not affected by the wind.
The low density fluff that sits in protected tree-line and below tree-line elevations is sluffing fast in steep terrain. Expect it to gain mass and accelerate as it moves downhill. Take care above and around terrain traps.
Touchy slabs are building and stiffening over a combination of facets, surface hoar, and sun crust on solar aspects. As the stiffness of the slabs increases, so too will the distance they propagate.
Sluffing from steep terrain will gain mass and speed. Given the new amounts of snow, sluffing is a certainty, so use caution above terrain traps. Stop periodically and move to the side, allowing that freight-train of pow to pass you by.
Touchy slabs continue to build and stiffen over a combination of facets, surface hoar, and sun crust on solar aspects. Large propagations (upto 300 m) and several skier remote triggered avalanches to size 2&nbsp; were observed today in KNP.
This layer is still touchy. Avalanche control was producing results on this layer today on the Sunshine Road and 93S.
Recent slab formation overlies a persistent weak layer of surface hoar, facets and crusts found predominantly at treeline and below. This layer is going to become more reactive with the next pulse of snow which begins on Saturday night.
Touchy slabs have been found primarily on East facing terrain below ridge crests between 2000 and 2400m.  These slabs are sitting on a persistent weak layer of crust and facets and are stiffening up, increasing the likelihood of wide propagations.
This layer is still touchy. Expect it to be most reactive on south aspects near tree-line. Typically, it will be about 40cm thick.
Expect fast sluffing in steep terrain today capable of gaining mass. Exercise good group management such that people aren't riding below or above one another
The low density snow from the past 2 days will sluff fast and gain mass in steep terrain. Practice good group management and avoid knocking your buddies, or yourself, over by your sluffs.
Fast-moving sluffs triggered by riders continue to be reported. These sluffs have been gaining mass in steep terrain, and could easily bowl you or your buddies over.
Plenty of new, loose snow is available for sluffing in steep terrain. Practice good terrain and group management, and avoid getting pile-driven into terrain traps by the snow you just skied.
We have seen the basal facets wake up at lower elevations in the Kootenay area. This may not be widespread, but will cause large avalanches if initiated.
With the cooling temperatures this will become less reactive to skier traffic. Large triggers such as cornice drops or large slab releases could still cause failures on the basal facets.
The recent storm snow, redistributed by wind is now over loading the snowpack. Several skier remote avalanches were observed today.
The recent storm snow, redistributed by wind is now over loading the snowpack. A field team in the Icefields area yesterday remotely triggered several slab avalanches and experienced extensive whumphing at tree line elevations.
With freezing levels climbing during the daytime, precipitation at lower elevations will be wet snow or rain. Loose wet avalanches will be likely depending on the amount of snow and if rainfull is heavy wet slab avalanche will also be a concern.
Although the new storm slabs are unlikely to produce very large avalanches they are still quite touchy.
A field team in the Icefields area on Wednesday remotely triggered several slab avalanches and experienced extensive whumphing at tree line elevations. Care is needed as you navigate slopes in this elevation band.
Where slab overlies the February 10th facet layer very touchy conditions exist. We have found this to be most prevalent at tree line elevations where remote and skier triggered avalanches have been occurring in the last few days.
Where wind slabs overly the February 10th facet layer very touchy conditions exist at tree-line and is borne out by numerous avalanche incidents in the last few days. The frequency of slabs stepping down to a deeper layer has increased dramatically.
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.
Heating on Tuesday will effect steep solar slopes and features such as cornices or snow near black bodies such as trees or rocks. Similarly,&nbsp; with some potential for rain at low elevations Wednesday, be cautious with the slab over the buried crust.
Two avalanches were triggered by the sun today.
Spring sun is gaining in intensity. Expect solar aspects to shed snow during the heat of the day, especially when the skies are clear.
Intermittent breaks in the cloudy weather is consistently producing loose dry sloughing to size 2 as the sun hits recent storm snow.
Intermittent breaks in the cloudy weather is consistently producing loose slides to size 2 as the sun hits recent storm snow.
Low elevation areas may see avalanche activity with the day-time warming, especially if the sun pops out.
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.
If the sun comes out or if there is a rapid un-forecast rise in temperature watch out for loose wet avalanches.
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.
Be cautious of lower elevation areas that have no crust formation from overnight. Loose avalanches are possible there.
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 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.
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.
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.
Later in the afternoon, loose moist/wet avalanches may start to come down if the sun is out and there is no cloud cover.
On Tuesday expect this problem only on lower elevation, sun exposed places. Watch out in steep cliffy areas or steep forest in the afternoon.
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.
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.
Dry loose snow avalanches are still possible in steep rocky and unsupported terrain.&nbsp; Solar triggering is likely with forecasted sunny skies.
Caution in steeper and rocky terrain especially on ice climbing terrain.
These slabs taper radically with elevation. Large slides resulted from failures in the recent storm snow over the crust that extends into the alpine.
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.
Rain to at least 1900m is saturating and weakening the snow. Below 1600m the wet surface snow will slide easily on buried crusts.
Persistent slab mainly around treeline is showing some signs of consolidation with less extensive whumphing observed on yesterdays field trip.
Rain to at least 1900m has weakened the snow. Below 1600m the wet surface snow will slide easily on buried crusts. Small sluffs may pick up snow, gaining mass. Be cautious in confined terrain features, such as gullies.
Test the shear found on the weak snow above the crust frequently. Although clean shears found on the facets alone are serious, the isolated areas that hold surface hoar should be treated with even more respect. More snow may make this more touchy.
50 cm of storm snow is likely to move fast in sufficiently steep terrain. Be aware of your sluff as it could pick up mass and turn into an avalanche.
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.
Sluffing in steep terrain should still be considered in your route planning as you travel today. Avoid exposure to groups above you in steeper confined terrain below treeline.
Some small pockets of surface hoar may still be present at and below treeline.
Some small pockets of surface hoar may still be present at and below treeline. Warm temperatures could be the trigger for avalanches to occur in these areas.
The weak layer of surface hoar and facets from December can still be found but are showing signs of settling out.
The weak layer of surface hoar and facets from December can still be found and may become susceptible to triggering with more snow loading.
Steep and shallow areas below TL will likely get saturated and lose support underfoot. Avoid consequential areas where heavy wet slides may push you over or into terrain traps. Low elevation ice climbs will be prone to wet sluffs and wet climbing.
The weak layer of surface hoar and facets from December can still be found and may become susceptible to triggering with new snow load.
The weak layer of surface hoar and facets from December can still be found and may become susceptible to triggering with new snow load. A skier accidental size 2.5 occurred starting from low angle terrain (27 degrees) on a NE aspect at treeline.
Up to 11mm of rain so far and currently 0 degrees at 2000m. Loose avalanches may also trigger slabs on deeper instabilities.
Small solar sluffs&nbsp; triggered the persistent slabs plus deep slabs failing on facets at the base of the snowpack Saturday. The snowpack has been weakened by heating and this is most pronounced at lower elevations, on solar slopes, and in thin areas.
Steep and shallow areas below TL are saturated and have lost much of their support underfoot. Avoid consequential areas where heavy wet slides may push you over or into terrain traps. Low elevation ice climbs will be prone to wet sluffs.
The weak layer of surface hoar and facets from December can still be found and may become susceptible to triggering with new snow load. A skier accidental size 2.5 occurred Saturday from low angle terrain (27 degrees) on a NE aspect at treeline.
The snow below treeline is saturated from the rain and if it slides, it will go to ground. Avoid consequential areas where heavy wet slides may push you over or into terrain traps. Low elevation ice climbs will be prone to wet sloughs.
Cooling temperature will help to stabilize the moist snow which will occur most rapidly near treeline as the freezing level falls over the next 24 hours. Until this happens the snowpack at lower elevations will remain unstable and avalanche prone.
Recent intense precipitation has fallen as rain at lower elevations. With higher freezing levels, expect that the surface snow will be saturated making loose wet avalanches likely.
Isothermal conditions exist at treeline and below. Many loose wet avalanches that have gouged down to ground have been observed below 1800 metres.
The snowpack is very weak at treeline and below elevations due to warm temperatures and isothermal snow conditions.
Below 2000m the snowpack has been hit mainly by rain. Surface crusts are just beginning to form and are all that there is to hold the lid on what remains of the soaked snowpack.
A weak temperature crust overlies isothermal conditions at treeline and below elevations. Many loose wet avalanches that have gouged down to ground have been observed in past 48 hours.
Avalanches are easily triggered below 1800m where wet snow runs on a crust. The forecast is for clouds, but should the sun emerge expect natural avalanches from steep solar aspects.&nbsp; Loose avalanches can gain mass and momentum quickly.
Below 2000m surface crusts are all that there is to hold the lid on a wet snowpack. Without a solid freeze these crusts remain weak and will break down quickly with further heating. Loose wet activity may also trigger wet slabs in isolated locations.
The moisture in the upper snowpack at lower elevations will be a concern to riders until lower level temperatures will remain consistently below freezing to form a solid crust.
Isothermal snow exists below 2000m. It will not take much solar input to break down a freeze, especially in steep gully terrain.
Ice climbers should be aware of loose wet avalanches out of steep terrain on solar aspects. The snowpack is saturated below 2000m currently and wont take much sun to break down any overnight freeze.
Watch for the sun to rapidly warm the surface snow and cornices, raising the hazard Tuesday morning with lingering warm air at upper elevations and a weak freeze expected. This activity will become unlikely beyond Tuesday afternoon with cooling.
The warm temperatures will create wet sluffs and rockfall on south facing slopes and gullies at and below treeline. Ice climbers should avoid this terrain, and instead search for north facing climbs where the cold temperatures will keep things solid.
The warm temperatures will create wet sluffs  on south facing slopes and gullies at and below treeline. Isothermal conditions may develop at below treeline elevations.
Warm temps and strong sun yesterday weakened the surface snow. Temps stayed above 0 to at least treeline and it is now raining lightly. The weak, moist surface snow may be easily triggered on steep slopes, gaining mass and traveling long distances.
The warm temperatures will create wet sluffs on south facing slopes and gullies at and below treeline. Isothermal conditions may develop at below treeline elevations.
At treeline and below warm temps and rain is further weakening the snowpack. The weak, moist surface snow may be easily triggered on steep slopes, gaining mass and traveling long distances.
Watch for early morning rain and isothermal conditions on low elevation ice climbs.
As temperatures increase this week watch for moist snow to develop at lower elevations where most of the snowpack has yet to refreeze. If the sun comes out this will happen quickly on solar slopes.
Warm overnight temperatures and ongoing rain continues to weaken the snowpack at lower elevations. Loose wet avalanches are easily triggered by skiers. These avalanches have the potential to run far and fast, especially where buried crusts exist.
Rain below 2000m Saturday means the snowpack will likely be isothermal below treeline and some treeline areas.
Watch locally for sun affect as lower elevation slopes may be isothermal Sunday.
Recent rain has helped produce isothermal conditions below treeline, especially in the afternoon as a result of daytime warming.
Watch locally for sun affect as lower elevation slopes may be isothermal Monday.
Heating on Thursday will likely provide quite a jolt to accumulating new now. Expect moist activity in the surface snow.
Watch locally for sun affect as lower elevation slopes may be isothermal Tuesday.
The sun is packing a punch these days. Watch out for loose wet sluffs in steep solar terrain if the sun is out.
Expect the sun to have a lot of power when it makes an appearance. Rising freezing levels make a solar trigger much more likely.
Warm temperatures prevented a re-freeze of surface snow. 10mm of rain fell this morning, further destabilizing the upper snowpack. Freezing levels at 2000m and sunshine will increase hazard on solar slopes. These avalanches can run far and fast.
Avalanche activity will depend upon overnight freeze and solar input Sunday. There is a lot of heat and moisture in the lower elevation snowpack.
The amount of overnight freeze and solar input will dictate the amount of avalanche activity Sunday.  There is currently a lot of heat and moisture held in the snowpack. 
More light rain is expected throughout today as freezing levels rise to near 2400m.
As heating breaks down thin surface crusts the entire moist snowpack below can become available to failure especially at lower elevations or on solar slopes. Watch overnight freezing levels closely and monitor the effects of the sun on the snow.
Avalanche activity will depend upon overnight freeze and solar input. There is a lot of heat and moisture in the lower elevation snowpack.
The amount of overnight freeze and solar input will dictate how big of a concern this problem is on Tuesday. Pay attention to how quickly the day is warming up.
Widespread loose wet avalanches have been occurring in the highway corridor and should be expected in the back country at and below treeline.
As the sun comes out on Thursday, expect the new snow to fail easily over the crusts.
30 - 50 cm's of new snow is slowly settling into a cohesive slab. This slab will be most reactive below 2000m where it overlies the Dec. 3rd surface hoar or facets, especially on Northerly aspects or on steeper sheltered glades.
20- 50 cm's of new snow is slowly settling into a cohesive slab. It will be most reactive in deeper snowpack areas where there is more than 30 cm's of new snow and below 2000m where it overlies the Dec. 3rd surface hoar or facets.
The storm snow has reached critical threshold (~30cm) on top of the Dec 3 surface. The trick is, it is located in sporadic locations across the forecast region. Be increasingly suspicious of steep open glades on shaded aspects at treeline and below.
30- 70 cm's of new snow is settling into a cohesive slab. It will be most reactive where there is more than 30 cm of new snow and below 2000m where it overlies the Dec. 3rd surface hoar or facets, found in sheltered terrain or northerly aspects,.
A 30-45cm slab is forming over a dangerous layer of surface hoar below 1900m. Treat all steep open slopes below treeline with suspicion until you can rule out this weak layer.

A weak layer that was buried in early January seems to be gaining strength, but this strength is being put to the test by wind loading, new snow and near-zero temperatures.
With forecasted weather, natural loose snow avalanches may subside, but expect it still to be a problem in steep terrain for skiers/climbers. Touchy cornices developed through the storm are new trigger to consider when assessing overhead terrain.
This problem exists in deeper snowpack areas - such as Kootenay Park where slabs have been formed by settled snow overlying the Jan 6 surface hoar layer. Watch out - these are touchy and propagate easily.
The January 4th interface is getting deep enough in the snowpack to be less reactive to skier loads. Triggered wind slabs, or larger loads like a group of skiers, may be sufficient to wake the Jan 4th up.
The January 4th interface is buried 50-80cm deep; still within range of being triggered by a person. The incremental loading of smaller storms onto this interface makes it a tricky one to predict when/if it will fail.
Incremental loading by a series of storms is making a weak layer down 50-80cm an increasing concern. This layer lingers in many areas and is sporadically reactive, making it tricky to assess. When it fails, however, large avalanches are the result.
A surface hoar layer now down 60-100cm is likely to be touchy after being overloaded by the storm. This layer lingers in many areas and is sporadically reactive, making it tricky to assess. When it fails, however, large avalanches are the result.
The January 4th interface was recently rapidly overloaded.  This layer is tricky to assess as it is not evenly distributed on the landscape.  It is also only sporadically reactive.  It can be found in many locations 60-100cm down in the snowpack.
30 cm of storm snow from Thursday continues to build into a slab overlying a weak facetted snowpack or decomposed surface hoar layer.

Expect any wet slide will have the potential to trigger preserved persistent slabs below. These slabs may take the season snowpack with it and will be notably destructive. South facing ice features could become very dangerous to an unaware climber
Persistent weak layer now buried around 100cm is still failing suddenly in snowpack stability tests a may potentially result in a large avalanche if triggered
Facets sit atop at crust buried up to a meter deep. This layer generally requires large triggers, but may increase in sensitivity during periods of warm temperatures.
This problem has not presented itself yet, but may if temperatures remain above freezing overnight.
With freezing levels rising to 1900m tomorrow the possibility of loose wet avalanches still exists. These could potentially occur on steep south facing rocky terrain.
Loose wet activity will be less active than on Tuesday, but with freezing levels still forecast to rise to ~2000m it is still a good idea to stay out of steep south facing terrain and rock gullies with overhead exposure.
The Jan 4 persistent weak layer now buried around 100cm dn is still sporadically failing in snowpack stability tests. If this layer awakens the result would be large and destructive.

40cm of storm snow sits on a strong crust and surface hoar which is poorly bonded in some locations. Field teams experienced whumphing on this layer yesterday. This low density slab has potential to gain alot of mass with a crust as the bed surface
Loose wet avalanches can be anticipated on solar aspects in the afternoon.
Daytime heating may cause loose wet avalanches at lower elevations. This activity will increase when the sun comes out during the next few days. Minimize your exposure to steep solar aspects when things heat up.
Expect the new snow to become less stable on solar aspects with daytime heating.
Freezing level expected to remain at treeline throughout the next 48 hours, even overnight. Expect sluffing and loose wet activity during the heat of the day, particularly on solar aspects.
Freezing level expected to remain at treeline for Monday evening. If this is the case, the snowpack will be further weakened and hazard will continue to increase if daytime temperatures get above 0 degrees or with a strong solar input.
Subject to intense periods of solar radiation. The overall snowpack is shallow and it does not take long for the Sun to make a significant impact to the hazard rating.
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 is subject to intense periods of solar radiation. In shallow snowpack spots and sunny conditions, the danger rating will rapidly increase.
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.
This problem is intended specifically for the Field ice climbs on Mts. Dennis and Stephen. We were there on Thursday, and the snowpack is slush. Hard to notice this if you just walk in the track, but be out of these gullies by noon at the latest.
This problem is intended specifically for the Field ice climbs on Mts. Dennis and Stephen, and Mt. Field, where steep gully routes will stat to see isothermal now conditions Sunday afternoon.&nbsp;
This problem is unlikely on Monday but will become significant later in the week with forecasted warm temps and intense solar radiation.  The danger rating will rapidly increase on thin solar slopes
This problem will increase with forecasted warm temps and intense solar radiation. The danger rating will rapidly increase particularly on thin snowpack zones and sun facing slopes.
As the new snow from Sunday is heated it will fail easily over the recently buried crust. As freezing levels rise through the week this problem should progress to affect more and more terrain.
Natural Loose Dry avalanches are likely in steep terrain on Tuesday, while human triggered sluffing in more sheltered terrain will remain likely throughout the forecast period.
The overnight crust will break down rapidly while the strong sunshine beats upon it. Be aware of the sun's effect on the slopes that you are traveling across, especially by late morning and into the afternoon.
As the snowpack warms and weakens during the day wet slab avalanche are more likely. Large and destructive wet slab avalanches have been observed recently.
As the snowpack warms and weakens during the day wet slab avalanche are more likely. Large and destructive wet slab avalanches have been observed recently. As freezing levels rise over the weekend more avalanche activity is expected.
This problem has been unreactive now for 5 days, and we are unsure if it even exists in alpine areas in Little Yoho, although it has been detected up to treeline on Mt. Field.
Up to 30cm of snow fell in the last 24hrs at treeline with another 15-25 expected today &amp; tonight. This new slab has buried a spotty surface hoar layer, that could be lurking. Expect this new load to take some time to stabilize.
Loose dry avalanches observed out of steep solar aspects at lower elevations, this loose snow has the potential to entrain the very faceted snowpack and gain mass quickly. Main terrain concern is when traveling in gully features while ice climbing.
Weak surface snow found at sheltered locations at lower elevations can fail easily in steep terrain. This loose snow has the potential to entrain more faceted snow and gain mass quickly particularly in confined terrain features like ice climbs
Storm slabs may be present especially at tree-line. If triggered, it is likely it will initiate the rest of the weak faceted snowpack.
Watch for solar inputs today on southerly aspects, most likely present on steep rocky unsupported terrain.
40cm of new snow has settled into slabs with the warm and humid weather. These continue to be reactive to tests around treeline where isolated SH has been found.
While this layer still exists in the alpine and should be considered in shallow areas it is mainly TL and below where this sugary snow in the lower snowpack continues to produce moderate shears. Take extra care BTL where this layer is shallow
This layer is mainly a concern below treeline where the facetted snow in the lower snowpack continues to produce moderate shears.
Loose Dry avalanches will fail naturally in steep sheltered area. These will grow in size by Monday. Avoid extended time in features like gullies Below Treeline, where you will be exposed to overhead hazard, and avoid skiing above your partner.
With temperatures climbing, all it will take is a brief period of clear skies and calm winds to have a major impact on steep slopes. Small solar or temperature triggered events are likely as the snow becomes moist.
Rain and warm temperatures expected in valley bottoms.
With up to 50cm of moist snow on the surface, loose wet avalanches are expected today and may be triggered by light loads such as skiers and even tree bombs. Although likely to be small, wet avalanches are powerful and can occur even on small slopes
Loose wet avalanches were observed on Thursday below 1900m. Despite cooler temperatures forecast for Friday this still may be a problem at lower elevations. Pay attention to day-time temperatures.
At low elevations the new snow is adding to loose, facetted snow sitting on a crust. Yesterday, fast sluffing while skiing steep pitches was reported. With the additional new snow these loose avalanches may gain enough mass to push you around.
These will be a problem in areas sheltered from the wind, especially in confined features like gullys. The problem will grow in proportion to new snow amounts.
Several buried weak layers in the middle of the snowpack are gaining strength over time as they become bridged, especially in the deeper areas closer to the Wapta. Dig down to see if they are present on your line, and how they are reacting.
These will be a problem in areas sheltered from the wind, especially in confined features, like gullys.
Several buried weak layers in the middle of the snowpack are gaining strength over time as they become bridged, but they may be waking back up during this avalanche cycle. Avoid avalanche terrain now.
With cooling temperatures the activity from this layer will decrease at treeline as the day progresses.
Rain to Treeline on Saturday will destabilize the snowpack. If the snow feels wet and punchy, avoid steep slopes. Isolated Wet Slab avalanches are also expected through the weekend. These are harder to predict.
Rain to treeline and warm temperatures will produce numerous avalanches of this type. Some of these will step down to ground producing full path releases.
With freezing levels in excess of 2200m Saturday, the surface snow at lower elevations has been failing naturally. Deeper avalanches could be triggered by these events as the entire snowpack has lost strength and will take some time to refreeze.
With freezing levels in excess of 2200m Saturday, the surface snow at lower elevations has been failing naturally. The entire snowpack has lost strength and will take some time to refreeze. Climbers: these events are very likely in gullies and cliffs
The snowpack is waterlogged Below Treeline. Wet slabs remain a possibility for Sunday: water in the snowpack has pooled above several midpack crusts.  These may act as failure plane.  Dig to look for the ingredients: wet layers below a drier slab.
Spring is here! With daytime or solar warming the upper snowpack is becoming moist in the afternoon.  This moist slab is touchy below 1900m where a crust down 30 is providing a good bed surface for wet avalanches.
Warming temperatures can cause new snow over crusts to quickly become touchy and slide easily as loose wet or moist slab avalanches.
No crust recovery overnight and new snow will insulate the upper snowpack at lower elevations. If the sun comes out today, this problem will reach high into tree line and could trigger wet slabs or glide avalanches.
No expectations for activity first thing in the morning but, as the day progresses expect to see snowballing, and loose slides on solar aspects at TL and below.
Pay attention to day time warming. Sunny skies and warm temperatures are increasing the avalanche hazard on sun exposed slopes in the afternoon.
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.
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.
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.
This problem will be reduced next few days as temperatures get cooler ; however, light rain may continue on Saturday. Keep this on your radar. Caution is warranted for ice climbers in gullies.
Wet snow flows like water in gullies during warm days, this problem becomes more predominant with daytime warming and rain. Steep gully features and thin rocky areas are the spots to avoid when this problems reactivity increases through the day.
At treeline and below, rain has saturated the snow that overlies a series of crusts. Warm temps are keeping the snow weak. Today's solar input will increase this hazard. This wet snow will be easily triggered and will run far on the crust.
At treeline and below, rain has saturated the snow that overlies a series of crusts. The refreeze overnight will break down with day-time warming, and solar input will rapidly weaken the crust during sunny periods.
New snow over old crusty surfaces may produce small natural avalanches with daytime warming.
Sunny skies tomorrow may induce a solar cycle on South-East through West aspects at treeline and below.
Isothermal conditions possible as melt freeze breaks down by late morning.
Recent storm snow and potential for solar radiation tomorrow may induce loose wet avalanches on SE through W aspects tomorrow at treeline and below.
Isothermal conditions are possible as crusts break down by late morning. Gauge the extent of the overnight freeze relative to how quick it will move into being reactive.

Late afternoon problem in steep, solar rocky terrain. Found to be entraining the surrounding, facetted snowpack and will build up volume quickly.
solar aspects and elevations below the freezing level
Cloud cover today should reduce the chance of loose wet slides on solar aspects. However if the sun does come out expect the recent 5-10 cm of snow to become reactive around rocks and trees on steep solar terrain.
Cloud cover today should reduce the chance of loose wet slides on solar aspects. However if the sun does come out expect the recent 5-10 cm of new snow to become reactive around rocks and trees on steep solar terrain.
Today's high freezing level of 2000m and the possibility of rain at lower elevations will weaken the snowpack and increase the possibility of loose wet avalanches.

There is potential for loose wet avalanches in the afternoon when the day heats up.
The sun is expected to make an appearance today which will heat up solar aspects quickly and weaken the surface snow, resulting in potential avalanches.
Rising FL and rain could destabilize surface layers resulting in loose moist avalanches. A Moderate re-freeze overnight should have formed a crust well into treeline on all aspects and into the Alpine on Solar aspects after yesterday's warm up.

Wind loading and cornice development could trigger large avalanches
Wind loading and cornice development could trigger large avalanches running far and fast.
In Sheltered areas, loose snow avalanches will have the potential to run far and fast on the crust in steep terrain.
Shallow snowpack zones and/or large triggers such as cornice failures  could trigger this deep layer. The consequences would be severe!

Depending on incoming snow amounts, loose snow avalanches will have the potential to run far and fast on the crust in steep terrain. If the sun comes out, these will be easier to trigger on solar aspects and will likely occur naturally.
Shallow snowpack areas and/or large triggers such as cornice failures could trigger this deep layer. The consequences would be severe!
This problem is more prevalent in shallow snowpack areas. Use caution moving from thick to thin spots as our area has an incredibly variable snowpack depth.
Warming temperatures on Friday and Saturday may make it possible to trigger weakness near the base of the snowpack in shallow areas.
Up to 35cm has fallen in this last storm. It appears to be bonding well.
This problem exists with day time warming and especially on solar aspects.
This problem will increase with day time warming and solar input, Travel early when the snowpack is frozen on solar aspects, and avoid during the heat of the day.
Strong possiblity of rain overnight and into the morning at lower elevation areas below 2000m
Facetted surface snow will slide easily on the newly formed December 9 crust, especially on sheltered steep smooth slopes. This will become less of a problem by tuesday as winds increase.
Numerous dry loose avalanches up to size 2 out of steep alpine terrain noted today on Mt.Wilson, Heads up climbers, There is a lot of overhead above you at the moment.
There are a variety of weaker layers down ~50-80cm depending on the area. These are the Dec 7 and 13th layers of facets, suncrust, and isolated surface hoar. Their reactivity is a bit sporadic but treeline seems to be the biggest culprit.

Dec. Surface hoar to 6mm can be found in sheltered locations up to 2000m and is reactive to skier traffic.
This problem is confusing. It appears to be stabilizing according to all reports but the layers remain visible in snow profiles, thus continue to deserve respect. Overall the problem is unreactive but our confidence is low, improving by the day.
Skier triggered avalanches sizes 1-2 on a layer of stellars at the storm snow interface in the Sunshine &amp; Little Yoho areas. Both were in steep features or on convex rolls.  The snow above is now cohesive enough that we are seeing slab propagation.

This layer is capped by a thin crust in many locations making it stubborn to initiate, however it has proven that it can still be triggered in sheltered locations. Avalanches caused by this layer may fracture above you!
Several persistent weak layers are present in the top meter of the snowpack. These are generally not reactive to skier traffic but we still get occasional reports of avalanches on one of the layers, usually on steep convex rolls or in thin areas.

Tuesdays storm is forecasted to arrive with high freezing levels.&nbsp; Rain at lower elevations will saturate snowpack making wet loose avalanches a concern especially in gully features where terrain traps may increase consequence.
Tuesdays storm is forecasted to arrive with high freezing levels. Wet loose avalanches will not be a concern once the temperature begins to drop on Wednesday.
Soft slabs will continue to develop as the new load settles. The potential exists for avalanches to step down to deeper layers.
The January 24th layer which is made up of Surface Hoar, Facets and Crusts (depending on elevation and aspect), is buried 60-80cm below the surface. 3 skier accidentals occurred yesterday on this layer; 2 at Rogers Pass and 1 outside of RMR.
The Jan 26th layer down 60-80cm is consist of decomposing surface hoar in sheltered areas and a crust on solar aspects. Activity appears to be slowing down on this layer, though it remains reactive to human triggers in isolated areas at Treeline.

The past week of cold temperatures has weakened the surface snow to where it sluffs easily in steep (40 degree) terrain. This is mostly a problem in narrow confined terrain like gullies or couloirs with a continuous steep incline.
Expect to find reactive storm slabs in sheltered areas. These could be especially touchy in lower elevation areas where they are sitting on facets above a melt freeze crust.
A bonus 25-30cm of cooler snow fell last night. This will readily sluff in steep terrain and could be a real hazard if it pushes you into a terrain trap, resulting in a deep burial.
The tail-end of the previous storm finished with 25-30cm of cooler, low density snow. This could power-sluff in steep terrain, and it would be a real hazard if it pushes you into a terrain trap, resulting in a deep burial.
Up to 70 cm of new snow this week may be more prone to slab formation with warming temperatures today.&nbsp;
Afternoon sun is packing a punch on lower elevation, SW through W slopes. Ice climbers: be extremely cautious. Overhead hazards can catch sun early.
Clear skies and warm temperatures are forecasted over the next few days. The March sun is strong, and will pack a punch on solar aspects, weakening the upper snowpack. Steep, rocky terrain with thin snowpacks will be the most susceptible.

Clear skies and warm temperatures are forecast for Friday. The March sun is strong and will pack a punch on solar aspects. Steep, rocky terrain will be the most susceptible.
The sun is packing a strong punch on south through west aspects when it comes out.
The new snow is likely to sluff in steep solar terrain anytime the sun comes out and rapid heating occurs. This can be amplified in thin rocky areas. Watch for this in gullies or couloirs that have a solar aspect above them.
As the sun comes out in the afternoon with the forecast light winds, expect a significant solar punch to moisten recent surface snow. This snow is already sitting on previous crusts and though small, these avalanches may run fast at far.
As the mercury slowly rises above 0 and the sun comes out, solar slopes will start to loose strength. Caution with your timing when traveling on/under these features.

An overnight freezing level of 1800m and forecasted rain at lower elevations does not bode well for the snowpack at tree line and below. There will be minimal crust recovery overnight and the snowpack will loose strength quickly.
Poor crust recovery Thursday night combined with rain below 1500m has weakened the snowpack at valley bottom levels. At higher elevations new snow over crusts will become moist quickly with solar inputs.
This problem is specific to Sunday when the temperatures rise dramatically. Be mindful of your overhead hazard and avoid sun affected slopes.
Rain and warm temperature will break down the snowpack at lower elevations and increase the likelihood for loose wet avalanche activity. This problem could release to ground causing small but destructive avalanches.
Sun and warm temperatures will cause the recent snow to slide. The warming will be most significant in low elevation steep, rocky, solar terrain in the front ranges east of the divide. Alpine winds will help to cool temperatures
Expect loose wet avalanches, especially in the heat of the day. Solar aspects TL and below are suspect.
Several wet loose avalanches were observed Monday afternoon on solar aspects Tree line and below. Keep this in mind when planning your travel times in these locations.
Freezing levels are expected at about 1700 meters. Places like Parkers ridge will most likely see dry snow. Further down the highway by Weeping wall could see a mix of snow and rain.

Solar input on Friday could create loose wet avalanche out of steep solar terrain at treeline and below.
Keep an eye out for rising temperatures and solar radiation
Strong solar radiation is forecast for today. Extra caution is required on steep slopes and thin snowpack areas where the sun will have the most affect.
Inverted temperatures and strong solar radiation today will likely initiate a wet loose cycle in steep, rocky, south facing terrain. Starting and finishing your day early will set you up for success, evading the most hazardous part of the day.
Solar radiation will be less intense on Friday due to cloud cover but if the sun does poke through, it will become wet quickly.  Also pay attention to the quality of the freeze overnight...
As all the new snow settles it may become more reactive as it becomes more of a slab.
Watch for storm slabs in open areas at treeline and below.
Warm temperatures, rainfalls, and the absence of overnight freeze will destabilize the upper portion of the snowpack. It will be very likely for skiers to trigger small loose-wet avalanches on steep slopes in areas where the snow has accumulated over the last few days.
The powder snow will gradually warm up during the day with the forecasted warm temperature (+ 7C in the valley) and southerly winds. It will be possible for skiers to trigger small loose-wet avalanches on steep slopes in areas where the snow has accumulated over the last few days.
