Most observers reported very widespread activity with numerous slab avalanches up to size 3 from all aspects and at all elevations. The common theme was that many slides showed very wide propagation, and quite a few released on surprisingly low angle slopes (25-35 degrees). More recently, a skier triggered size 2 persistent slab avalanche was observed in the north of the region around Birkenhead Lake.

</style><p class="p_CC664AAA"><span class="s_3FE45715">There were no new reports of avalanches on Friday; however, there is more evidence of a fairly widespread natural cycle earlier in the week. Many observers reported slabs up to size 3, mainly from steep open features at and below treeline. Observations are generally limited in the alpine but a couple observers noted a surprising lack of slab activity at higher elevations. Cooler and drier conditions should help stabilize the snowpack and reduce the likelihood of triggering. That being said, there is still potential for triggering lingering persistent weaknesses and producing very large and destructive avalanches. </span></p>

These avalanches likely occurred on Tuesday or Wednesday and failed in response to rain and warming below treeline. With forecast cooling, this type of activity should taper-off. Expect recently formed wind slabs to be sensitive to human triggering at higher elevations.</span></p>

Three skier triggered avalanches were also reported. One was remotely triggered from 10m away on an east aspect at 2000m. This released down 70cm suggesting it failed on the early January surface hoar layer. A size 1.5 was reported on a west aspect at 1900m failing down 100cm on the early January layer. The third was a size 1.5 on a northeast aspect at 1800m failing down 40cm also on the early January layer.

Reports from Monday include more evidence of natural avalanche activity that occurred during or post storm late last week with observations of recent widespread persistent slab avalanches up to Size 3.5. On Saturday, there was a report of a remotely-triggered size 2.5 avalanche that likely failed on the January 9th surface hoar. This slide occurred on South aspect at around 1200 m. Explosives control work in Ningunsaw Pass also produced numerous slab avalanches to size 3. Most of these slides were from N-E aspects in the alpine and at treeline. Many initiated on the mid-January surface hoar but then stepped down to deeper persistent weaknesses. This type of avalanche activity highlights the current challenge of dealing with buried persistent weak layers that are becoming harder to trigger, but if triggered they will produce very large and potentially deadly avalanches.</span></p>

On Saturday, there was one report of an intentionally skier triggered size 2 slab avalanche in the Ashman area. This slide may have released on the buried mid-Jan surface hoar layer, down around 50 cm in this area. There was also a report of a size 2.5 slab that was remotely triggered from the far SW corner of the region on Sunday.

The avalanches occurred in response to new snow and wind on Friday. Last week, a skier remotely triggered a size 3.0 slab avalanche from 20 metres away that released on the early January surface hoar. This avalanche happened at 2300 metres on a south-southeast aspect in the Duffey Lake area. The fracture propagated 350 metres and ran 750 metres to the valley bottom. This speaks to the ongoing touchy persistent slab problem in the north of the region. Looking ahead, forecast rising freezing levels and solar radiation should spark a round of loose wet avalanche activity on sun-exposed slopes.

The aspect and elevation are unknown; however, the mid-January surface hoar was the likely culprit. This speaks to the ongoing touchy persistent slab problem in the north of the region. On the same day, 2 people were partially buried and 1 person was fully buried in a size 2.5 slab avalanche on a south-facing alpine feature in Marriott Basin. The exact failure plane of the slide was unknown, but warming was thought to have played a major role in initiating the human triggered avalanche. Hats off to everybody who pulled-off a successful rescue. Check out the great Mountain Information post for more details. On Monday, widespread loose wet avalanche activity to size 3 was observed in steep, sun-exposed terrain. The gradual cooling trend will make heat-induced surface avalanches less likely; however, very large persistent slab avalanches are still possible in the north of the region.</span></p>

Natural avalanche activity up to size 3.0 (average size 2.0 to 2.5) occurred today in specific Alpine terrain. Most slab avalanches occurred immediately below ridge crests under cornice features, or were triggered by loose dry avalanches from very steep alpine terrain. Fracture lines ranged from 50 to 100cm deep. The activity occurred on NE, E, S and SE aspects at elevations of 2400m and above. In addition, solar triggered slides up to size 1.5 occurred in the afternoon on steep S, SW and W aspects.</span></p>

This includes soft storm slabs up to 30cm thick, wind slabs in lee and cross loaded features, and loose wet avalanches at lower elevations. Explosives also released a couple size 2 cornices which triggered soft slab avalanches on the slopes below. On Saturday, ski cutting produced size 1-1.5 soft slab avalanches up to 30cm thick in lee and cross loaded features in the alpine and at treeline. Explosives released cornices size 1-2 in the alpine. Rain-soaked lower elevations are unlikely to see much in the way of avalanche activity on Tuesday, but storm slab avalanches are expected to be reactive to human-triggering at higher elevations with ongoing snowfall and wind continuing overnight Monday. Wind loaded features should be the biggest concern but a more widespread storm slab avalanche problem may develop in the deepest snowfall areas.

Crown lines varied from 20-40cm with widespread propagation noted in some locations. The storm snow became more reactive through the morning as it became more wind affected by the Southerly winds with a few skier accidental's to size 1.5 observed in the Flute region. Size 1.0 loose solar induced surface instabilities were evident by 10am. Cornices have continued to grow throughout the past week with large cleaves opening behind some of them. The older buried layers of surface hoar and crusts are now generally well bridged over but step down fractures may still be possible with large loads such as a cornice fall.</span></p>

These slabs were typically 20-40cm thick and were failing within the recent storm snow. However, a couple storm slabs were also reported at 1600m and were failing on a rain crust. One wind slab was remotely triggered from 10m away on a bench feature. One natural size 2 storm slab was reported from an east aspect at 1900m and had a slab thickness of 20cm. Explosive use on Tuesday also produced several size 2 storm slabs and several size 2 cornice releases. Lots of avalanches were also reported through social media and there are some very impressive photos floating around due to the clear weather. Storm slab avalanches are expected to be remain very reactive to human-triggering at higher elevations with ongoing snowfall and wind continuing Thursday.

On Thursday, a natural size 3.5 persistent slab avalanche was reported in Bear Pass. The occurred on a northwest aspect at 1350m elevation and released on the late-February surface hoar layer. A natural size 2.5 storm slab was reported from the same area and appears to be on a northern aspect. A skier triggered a size 2 cornice in the same area which did not trigger a slab on the slope below. In the south, a natural cornice release triggered a size 2 persistent slab on a north aspect at 1700m which released down 80cm on a layer of surface hoar. Lingering wind slabs may still be reactive to human triggering on Sunday. There is extra concern for the deep surface hoar layer that seems to be most reactive north of Stewart but may also exist in the south.

This avalanche occurred on a northwest aspect at 1350m elevation and released on the late-February surface hoar layer.</span><span class="s_9387EF2" /></p>

In the northern part of the region there were some reports of solar induced slabs to size 3 on south aspects, and natural cornice falls. One cornice fall triggered a size 4 avalanche that released on the ground and cleaned out an entire bowl. It was 1km wide and ran 1.5km.</span></p>

They formed in response to new snow and wind and were mostly triggered on north to northeast facing terrain at treeline and in the alpine. No new persistent slab avalanches were observed in the South Columbia region on Saturday; however, a few were noted in the size 2-3 range in the neighboring North Columbia and Kootenay Boundary regions sliding on the late February layer. They failed either naturally or under light loads on various aspects at treeline and in the alpine. This intermittent pattern is spooky, and sporadic persistent slab avalanches can be expected in the South Columbia region as well. With more snow and wind on the way, watch for new wind slab activity throughout the region on Monday.</span></p>

On Friday a size 2 slab avalanche was remotely triggered by a snowmobile from a distance of 3 metres on Frisby Ridge near Revelstoke. The avalanche was about 90cm deep and occurred on a northeast facing convex roll at about 1950m. On the east side of the Selkirks, a size 3 natural slab avalanche was also observed failing on the same layer. It occurred on a west aspect at 2300m. The slab was 70cm deep, 350m wide and 1000m long. Most notably, a sledder was killed on Sunday in a size 2 slab avalanche in the Monashees just north of Shuswap Lake. The avalanche, which likely also failed on the late February layer, occurred on a west facing convex roll at 1830m. The slab was 40-80cm deep, 60m wide and 65m long. The subject was found after more than an hour of probing as rescuers were not able to obtain a transceiver signal. Transceivers are essential equipment; if the subject was wearing a functioning transceiver, it may have made difference.</span></p>

On Friday a few different very large avalanches (to size 3.5) were observed that failed naturally on southerly facing alpine features. These avalanches were likely triggered by falling chunks of cornice impacting thin snowpack areas in the far north of the region. Debris ran down the track well into the below treeline vegetation band.</span></p>

The avalanches formed in response to new snow and wind on Sunday night. Explosives control also triggered older storm slabs including a size 3 avalanche on a southeast facing alpine slope. Persistent slab avalanches continue to fail on the late February weak layer. A sledder was killed on Sunday in a size 2 slab avalanche in the Monashees just north of Shuswap Lake. The avalanche occurred on a west facing convex roll at 1830m. The slab was 40-80cm deep, 60m wide and 65m long. The subject was found after more than an hour of probing as rescuers were not able to obtain a transceiver signal. Although this avalanche occurred only a few kilometers north of the regional boundary in the North Columbia region, similar conditions exist in the South Columbias. This was indicated by another avalanche in the southeast corner of the region (see the Mountain Information Network post near Kokanee Glacier). The avalanche, which resulted in a partial burial, was remotely triggered and was in the size 2 range.</span></p>

Solar radiation and increasing freezing levels will become the driver for natural avalanche activity in the coming days.</span></p>

In the Lindeman Lake area over the weekend, loose wet avalanches were reported releasing from solar aspects on low elevation slopes. The forecast stormy weather over the next few days is a perfect recipe for building new cornices and wind slabs at higher elevations. The rapid warming trend after the storm is very likely to trigger any weakness in the snowpack; expect storm snow to release as loose wet avalanches on solar aspects, new wind slabs to be easy to trigger where they are sitting on old hard surfaces, and cornices failing naturally. In shallow weak areas like the Powder Valley and The Wheaton, expect facetted snow to become very weak and possibly become isothermic (the whole snowpack approaching zero degrees &quot;like a slurpy&quot;) and release down to the ground.</span></p>

At the time of publishing no other avalanches were reported, although this may reflect a lack of observations rather than actual conditions. The sun has become the main driver for avalanche activity. Although warming has promoted settlement and strengthening within storm snow from last weekend, loose wet avalanches and cornice falls have become the most common avalanche type. A major concern, however, remains isolated yet destructive releases on deeper weak layers which formed earlier in the season (see snowpack description). Avalanches on these layers could run surprisingly long distances, and may be triggered by a cornice fall, a surface avalanche in motion or extended periods of warming.</span></p>

Some of these releases were over 2m deep releasing on old weak layers. In the south, a natural icefall triggered a size 2.5 slab avalanche. Several loose wet avalanches were also reported. Conditions are expected to improve quickly when the temperatures drop on Saturday but there has been so much heat added to the snowpack over the last few days that some of the deep persistent weak layers may remain reactive for a few days. Once the snow surface develops a widespread supportive crust layer, it will become unlikely to trigger any deep weaknesses. Lingering cornices may remain reactive to human-triggering until there has been substantial cooling.</span></p>

These slabs were on high elevation north-facing terrain and were likely failing on an old layer of surface hoar which was buried at the end of January or weak facets near the bottom of the snowpack. There have been no new reports of avalanches over the weekend which is likely due to the region entering a melt-freeze cycle with colder overnight temperatures. For Tuesday, new snow with strong southerly winds is expected to quickly form new wind slabs in leeward features. This new snow will sit on top of a strong melt-freeze crust which may increase the reactivity of newly formed wind slabs. On Wednesday, loose wet avalanches are expected to be a concern when the sun hits the new storm snow and wind slabs will remain reactive to human-triggering. On Thursday, if enough snow accumulates, a storm slab problem may develop. Widespread problems can be expected once around 25cm of new snow accumulates over the melt-freeze crust in wind-sheltered areas. The biggest hazard on Thursday will be in wind-loaded leeward features.</span></p>

The slabs were 40-50cm thick and were suspected to have failed on a crust from the end of February. Explosives also triggered two size 2.5 wet slab avalanches. Loose wet sluffing up to size 2.5 was also reported.  On Wednesday, natural loose wet avalanches up to size 1.5 were reported. Skiers and explosives were triggering wind slabs up to size 1.5 in leeward features and on steep rolls. A couple point releases triggered slabs up to size 2.5. With warm and sunny conditions continuing, spring avalanche problems are expected to be the primary concerns. Loose wet avalanches and large cornice falls are expected throughout the forecast period. Wet slabs and deeper persistent slab avalanches may be possible while the temperatures remain high and overnight recovery is poor. Lingering wind slabs may also still be a problem on high elevation north aspects.</span></p>

Over the weekend, loose wet sluffing is expected on steep sun exposed slopes and cornices will become weak with daytime warming and sun exposure. Lingering wind slabs may still be reactive in exposed high elevation terrain.</span></p>

By the end of the storm, enough snow has accumulated in the south of the region for the formation of storm slabs. In many areas, the new snow is expected to be poorly bonding to the old interface. However, limited reports over the weekend suggest that the new snow is low density and no wind transport has been observed. With the current uncertainty about the new snow, it is best to watch for signs that the new snow is settling into a slab and look for areas where the new snow may be stiffer due to wind loading. Caution is needed throughout the region in wind loaded areas where the old wind slabs from the end of last week may still be lingering.</span></p>

Storm slab avalanches have the potential to step down to this layer which would increase the size and destructive potential of resulting avalanches.

This is expected to continue during the storm. The new snow sits over a highly variable and weak interface which should increase the reactivity of the new storm slabs. The surface hoar layer from mid-November may still be reactive in isolated areas. As new load accumulates over the weekend, this layer is expected to increase in reactivity where is still exists. Storm slab avalanches have the potential to step down to this layer which would increase the size and destructive potential of resulting avalanches. Old rain crusts from November which have recently become faceted as well as basal faceting in shallow snowpack areas will also get tested during the storm with the rapid loading of the snowpack. Until more information is available, it is best to assume deep release avalanches are possible. </span></p>

There is a bit of uncertainty regarding how last week's snow will bond to old surfaces that formed during the cold snap. Given this, there is still potential for skier and rider triggering in sheltered areas where buried surface hoar may exist, or in wind exposed terrain where wind slabs maybe sitting on facets.</span></p>

</style><p class="p_CC664AAA"><span class="s_3FE45715">On Thursday, two size 2 persistent slab avalanches were triggered with explosives in the southeast part of the region. The avalanches ran on weak faceted (sugary) grains between 50-100 cm deep. Earlier in the week, wind slabs were reactive to both explosive and human triggers (mostly size 2), while some stepped down produce larger persistent slab avalanches in the size 2.5-3 range. On Saturday, wind slabs are expected to be the primary concern resulting from new snow and strong to extreme southwest winds from earlier this week. There is a bit of uncertainty regarding how last week's snow will bond to old surfaces that formed during the cold snap. Due to these potentially persistent weak layers, wind slabs may remain sensitive to human triggering for some time. In the southeast corner of the region, there are concerns about a deep persistent problem. A weakness at the bottom of the snowpack has produced some large avalanches recently. Human triggering may be possible in thin areas or smaller avalanches have the potential to step down to this layer resulting in full depth avalanches.</span></p>

West of Terrace there was evidence of avalanches running in the storm snow up to size 3 on both north and south facing slopes. Explosive control on Friday produced several size 1.5-2 avalanches on northeast aspects at treeline. Wind slabs will remain touchy for a few more days as moderate winds continue to transport loose snow.</span></p>
