</style><p class="p_CC664AAA"><span class="s_AA239A9B">On Tuesday, a natural cornice release triggered a size 1.5 storm slab on a northwest aspect at 2050 m elevation. Skiers triggered a size 1 wind slab on a west aspect at 2100 m and a size 1 storm slab at 2000 m. These were 20-25 cm thick. On Monday, a natural cornice release triggered a size 3.5 deep persistent slab on a north aspect at 2500 m released on glacier ice and ran to valley bottom. Several other large natural cornice releases and storm slabs avalanches were reported, with a few stepping down to deeper layers. </span><span class="s_3FE45715">Over the weekend, a widespread avalanche cycle occurred with avalanches up to size 4.5. This included very large cornice releases, avalanches releasing on layers near the base of the snowpack, propagations over 1 km wide, and mature timber being broken. </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 avalanches.</span></a><span class="s_AA239A9B" /></p><p class="p_CC664AAA"><span class="s_3FE45715">On Thursday, sun is expected to drive the hazard. If there is are long periods of strong sun, expect sluffing from steep sun exposed slopes, cornices will become weak, and persistent slab avalanches could fail naturally. With the recent avalanche activity and several weak layers within snowpack waking up, it is a time to be very conservative with terrain selection.</span></p>
