</style><p class="p_CC664AAA"><span class="s_AA239A9B">On Thursday, a natural cornice release occurred on a north aspect at 2100 m. A few natural wind slabs were reported as well as a few solar triggered loose avalanches. Skiers were triggering wind slabs and storm slabs up to size 1.5, mainly on northwest through east aspects in the alpine. Most of these slabs were 10-30 cm thick but one was 50-60 cm thick and release on the mid-March crust. Explosives triggered a few cornices and slabs 25-50 cm thick. One of the cornices triggered a deep slab which slid on the November crust. On Wednesday, a natural size 2 slab was observed on a south aspect at 1800 m which was 100 cm thick. Natural sluffing up to size 2 was reported as well as two cornice failures. One of these triggered a size 3 slab which released down 200 cm. </span></p><p class="p_CC664AAA"><span class="s_3FE45715">On Saturday, storm slabs are expected to be reactive at higher elevations, especially in wind loaded terrain and on steep convexities. Cornices are large and may become weak with daytime warming or during stormy periods. We are in a low probability, high consequence scenario for persistent slab avalanches failing on buried weak layers. </span><a id='GoToAdded' href="http://www.avalanche.ca/blogs/novemberfacetsmarchlphccycle" target="_blank"><span class="s_B5813F7D">Click here for more details.</span></a><span class="s_3FE45715"> </span><a id='GoToAdded' href="http://www.avalanche.ca/blogs/lp-hc-2017march" target="_blank"><span class="s_B5813F7D">Click here for photos of the recent large avalanche cycle.</span></a><span class="s_AA239A9B" /></p>
