Our uncertainty revolves around whether the snowpack will get a chance to re-freeze in the morning before the sun starts to heat the snowpack.

On Thursday, several natural storm slab avalanches up to size 2.5 were observed. Several natural cornice releases triggered slabs up to size 3, many of which released on the late-March crust down 40-80 cm. A skier also triggered a 30 cm thick storm slab which stepped down and released a size 2.5 persistent slab which failed on the late-March crust down 80-100 cm. </span></p><p class="p_CC664AAA"><span class="s_AA239A9B">On Sunday, the recent storm snow is expected to remain reactive to human triggering, especially in wind loaded terrain.

Saturday's fatal avalanche accident on Mt. Harvey, although not in the Sea To Sky region, does highlight several of the risks posed by cornices: multi-ton snow boulders serve as large triggers potentially releasing large avalanches on the slopes below, they can break well back making for tricky travel along ridge crests. It's all the more tricky when visibility is obscured in fog or heavy snow, if the easiest pathway (flat, hard snow, open straight line) is within the danger zone, or when they're so big that you need to be 10 or 15 or more metres back from the edge to remain safe.</span></p>

On Saturday there was an accidentally triggered size 2 wind slab reported in the Valhallas. I think this kind of shallow wind slab in alpine terrain is representative of a lingering wind slab concern: localized pockets, lee and cross-loaded features, around 20 to 30 cm thick. Although not in this region, Saturday's fatal avalanche accident on Mt. Harvey (South Coast Mountains) highlights several of the risks posed by cornices: multi-ton snow boulders serve as large triggers potentially releasing big avalanches on the slopes below, and they can break well back making for tricky travel along ridge crests.</span></p>

Control work produced numerous other storm slabs to size 2 on northwest, north, northeast, southeast, south and southwest aspects.

These avalanches occurred in response to new snow and wind. </span></p><p class="p_CC664AAA"><span class="s_3FE45715">No persistent avalanches were observed over the weekend. That isn't to say that weaknesses don't exist in the snowpack and that large avalanches aren't possible. It was only a few days ago when explosives control produced a size 2.5 and a size 3 slab avalanche that stepped down to the mid-December layer on north to northwest aspects above 2000 m. Over time, we'll likely transition to a low-probability/ high consequence avalanche pattern with these buried persistent weak layers. This makes terrain selection harder as some slopes may not react to the weight of a rider, while other slopes may be waiting to surprise with nasty consequences.</span></p>

A size 3.0 naturally triggered slab avalanche occurred in the past 24 hours on a steep north aspect in the Alpine.

More notable are the numerous explosive triggered, very large avalanches up to size 3.5 that where reported near Whistler on Thursday. These avalanches started in the storm snow and then stepped down to the early January and even the mid-December crusts which resulted in very large avalanches running full path. They occurred on northwesterly aspects below rocky ridgetops at around 1950 m. Although these layers are over 200 cm beneath the snow surface, a large trigger such as a falling cornice or a smaller human triggered avalanche could very likely &quot;step-down&quot; to these layers resulting in large and destructive avalanches.</span></p>

Slopes of all aspects and elevations ran full path and reached valley floor. In some cases, mature timber was smashed.

Avalanches are most likely to be triggered with a large load (like a snowmobile landing a jump, a cornice fall, or a solar-triggered avalanche stepping down), or from a thin-spot trigger point, like around trees or rocks. You might be surprised by how large an avalanche can be triggered and how far it could run.</span></p>
