The avalanche was on a North aspect and the crown depth was 1-2 m deep.  Thursday, a size 2.5 natural slab avalanche occurred near the Coal Creek road. The debris just reached the road, didn't block it but the air blast covered the road with branches. Explosive controlled and skier controlled slab avalanches up to size 2 continue to be reported. Conditions remain ripe for skier and sled triggers, with wide propagations and large avalanches.</span></p><p class="p_3F50020"><span class="s_3FE45715"> </span></p><p class="p_3F50020"><span class="s_3FE45715">Check out the </span><a id='GoToAdded' href="http://blogs.avalanche.ca/category/southrockies/" target="_blank"><span class="s_B5813F7D">South Rockies Blog</span></a><span class="s_3FE45715"> for recent photos and insights of what people are seeing out there.</span></p><p class="p_3F50020"><span class="s_3FE45715"> </span></p>

Forecasters worked their way up a treed ridge and remotely released 2 large avalanches from 30m and 100m away. The specifics are: 2 avalanches, both Sz2, skier remote(30 &amp; 100m), NE-E aspect, 35-45 degrees, the terrain was crossloaded and upper treeline. The furthest avalanche was triggered from the opposite side of the ridge. Both slides ran to mid path.

Most of the storm snow avalanches are size 1.5-2.0, however one was reported to be size 3.0 where the storm slab is now 80 cm thick. Explosives control released some large avalanches down to the early February persistent weak layer. There were also a couple of accidentally triggered storm slab avalanches, one that buried a sledder on a northwest aspect in the alpine. Neighboring forecast regions have reported large avalanches initiating in the new storm snow, then stepping down to deeper layers, some  running full path to the ground.  The South Columbia's reported a size 4.5 on a south aspect than ran more that 1500 vertical metres.</span></p>

Some of these were explosive triggered, but a number of these were naturals. Cornice failures are high on the list of probable triggers, as well as wet avalanches originating in the alpine on south facing steep slopes. Overnight freezing will lower the hazard temporarily, but rising temperatures will bring it back. Lower elevations will continue to see loose wet avalanches that can contain a surprising amount of snow once set in motion. We are not seeing skier or rider triggered avalanches being reported, although we have had reports from back-country users of some very large, ( and mostly wet) natural avalanches. </span><a id='GoToAdded' href="http://blogs.avalanche.ca/category/southrockies/" target="_blank"><span class="s_9255B882">See the most recent South Rockies blog.</span></a><span class="s_AA239A9B" /></p>

Once the snow surface starts to become moist avalanche danger is on the rise. Your best bet is to start and end your hike early to avoid the heat of the day. </span></p><p class="p_33E27566"><span class="s_3324E81"> </span><span class="s_3FE45715">Avoid exposure to steep south facing slopes when the sun is strong.

Loose wet avalanches are occurring at lower elevations where the precipitation is falling as rain. The moist new storm snow appears to be bonding well to the old surface on lower angle slopes and the slab problem does not appear to be widespread. There is still a major concern for the deeply buried weak layers where they still exist and a small avalanche or sluff may have the potential to trigger one of these layers.

At high elevations, wind/storm slabs are expected to be the biggest concern. Reports of natural activity to size 2.5 on Tuesday. Loose wet avalanches are occurring at lower elevations where the precipitation is falling as rain. The moist new storm snow appears to be bonding well to the old surface on lower angle slopes and the slab problem does not appear to be widespread. There is still a major concern for the deeply buried weak layers where they still exist and a small avalanche or sluff may have the potential to trigger one of these layers. A human may be able to trigger these layers from a thin area like a rock outcrop.</span></p>

On Wednesday, one observer from the McMurdo Hut southwest of Golden reported seeing numerous avalanche crown lines and significant debris, particularly from alpine terrain. Natural activity should taper off this weekend but there may be lingering potential for triggering fresh wind or storm slabs higher in the alpine.</span></p>

These avalanches are suspected to have all run on the recent buried rain crust.</span></p>

On Sunday, explosive control produced storm slabs size 1-2. On Saturday, reports of natural storm slab activity up to size 2 at treeline and in the alpine. Ski cutting and explosive control also produced numerous storm slab avalanches, some of which stepped down to an old crust layer in the middle of the snowpack. The deepest slab released was reported to be around 1m thick. I expect with the new storm loading on Tuesday and Wednesday morning that we will see new storm slab activity throughout the region.</span></p>

Best case scenario is that the new storm snow will initiate a widespread natural avalanche cycle, however; if it doesn't reach its tipping point then it will likely be primed for rider triggers.</span></p>

Human-triggered persistent slabs remain the main concern for the foreseeable future.</span></p>

On Monday, isolated natural activity was reported in Rogers Pass. On Sunday, several natural size 3 glide slabs were reported around Nakusp. These released on the ground with average depths of 2.5m. These were east aspect between 1200 and 2000m elevation. Also reported was a size 2 which was remotely triggered by a helicopter from 100m away. This occurred on a west aspect at 2200m and released down 1m on the mid-Dec layer. Finally, a snowcat intentionally started a size 2 avalanche by pushing snow over the edge of a ridge. This also released on the mid-Dec layer down 60-100cm and occurred on a NE aspect at 1900m. Natural avalanche activity is not expected on Thursday.

One was a size 2.5 slab on a NW aspect at 2300m, while the other was a size 3 on an E aspect. The crowns were 120-150 cm deep. On Saturday, skiers triggered numerous persistent slab avalanches to size 2 in the north of the region, in some cases remotely from a distance of 10m. On Sunday, a couple of persistent slab avalanches in the size 2.5 range were triggered between 2100 and 2300m from a distance of up to 100m. Avalanche activity has slowed, but there is still the potential for human-triggering of large avalanches.</span></p>

</style><p class="p_CC664AAA"><span class="s_3FE45715">On Thursday, explosives triggered a size 2 avalanche. No new avalanches reported on Wednesday. Explosive control on Tuesday produced two size 2 slab avalanches in the deeper western part of the region. These avalanches released on the mid-Dec layer down 90-100cm on steep north aspect slopes. Some natural avalanche activity is possible on Saturday in specific areas including fast sluffing from steep terrain and wind slabs in leeward alpine features. Small avalanches have the potential to step down and trigger a persistent slab which would greatly increase the consequences. Skier triggering is likely in wind loaded areas and steep terrain, and remains possible for persistent slabs where the tricky mid-December layer is still intact.</span></p>

There have been some concerning deep releases over the last week. On Monday, skiers triggered a slab on the mid-Dec layer. On Tuesday, skiers triggered a larger avalanche on the mid-Dec layer and snowmobiles purportedly triggered a slab that released near the ground, presumably on the Nov layer. Explosives also triggered a slab that released on the Nov layer near the ground. There are three major concerns for the weekend and into next week: (1) Small, recently formed slab avalanches may have the potential to step-down to a deeper layer. (2) Prolonged warming at higher elevations will potentially make it easier to trigger one of the deep persistent layers. (3) When sun is coupled with the warm air on Sunday, natural avalanches may occur on south-facing slopes and may step down to deeper layers. These problems are probably not enough to drive the danger rating to High but create a high-consequence Considerable problem which may last for several days.</span></p>

There were a few close calls during this cycle. On Sunday in the Hankin area, a skier accidentally triggered a size 2.5 avalanche which resulted in a full burial and minor injuries. The avalanche was reported to have occurred on a wind-loaded, north-facing slope. The avalanche initially failed on the January crust/surface hoar combo, and then stepped-down to the November crust and basal facets. On the same day in the Sinclair area, a snowmobile may have been the trigger for a size 3 avalanche. The avalanche had a crown between 1 and 2 metres, and propagated up to 200 metres wide. It occurred on a wind-loaded, north-facing alpine slope and may have failed on the November crust facet combo. On Tuesday 27th, a couple of small skier-triggered avalanches were reported. One occurred on a steep roll over at lower treeline elevation and ran on the mid-January layer. The other was a small section of wind slab that pulled off a ridge line in wind affected terrain.</span></p>

Many avalanches failed within the recent storm snow, although numerous avalanches also failed on persistent and deep persistent layers. Most of the avalanche activity had subsided by Tuesday 27th, although human triggered avalanches were reported to size 2 and explosive controlled avalanches were reported to size 2.5. With forecast snow and wind, I expect ongoing storm slab activity, and the potential for deep destructive persistent slab avalanches remains.</span></p>

On Monday there were several size 2.0-2.5 loose wet and wet slab avalanches released with explosives at Kootenay Pass, and a size 3.0 natural avalanche in the backcountry near Whitewater ski resort on a Southeast aspect with a very wide propagation that probably released on the mid-January persistent weak layer during a period of strong solar radiation. Moist or wet loose snow avalanches have been reported from several areas up to size 2.0 over the past few days during the warming event. On Saturday a skier triggered a size 2 persistent slab which failed on the mid-December layer. This was a surprising result because it was on a well-supported, concave terrain feature (which had also been heavily skied). </span></p>
