</style><p class="p_CC664AAA"><span class="s_3FE45715">On Saturday, a group of snowmobilers triggered a fatal deep persistent slab avalanche near Invermere. The avalanche was triggered on the layer of weak faceted grains near the base of the snowpack described in the Snowpack Summary. The avalanche was 200 to 400 m wide and ran approximately 900 to 1100 m. Two snowmobilers were caught. </span><a href="https://www.avalanche.ca/map?panel=fatal-accidents/fatality-mtbrewer-2019-01-12" target="_blank"><span class="s_B5813F7D">See here for more information.</span></a><span class="s_AA239A9B"> Within another group, a snowmobiler remotely triggered a size 2 avalanche from 40 metres away. </span><a href="https://www.mountainconditions.com/reports/deep-instabilities-waking" target="_blank"><span class="s_9255B882">Check it out here.</span></a><span class="s_AA239A9B" /></p><p class="p_CC664AAA"><span class="s_3FE45715">On Friday, five large to very large (size 2 to 3.5) deep persistent slab avalanches were observed. They were triggered naturally, by skiers, and by explosives in alpine terrain. Otherwise, numerous wind and storm slab avalanches also released small to large avalanches (size 1 to 3), on all aspects and generally in alpine terrain.</span></p><p class="p_CC664AAA"><span class="s_3FE45715">The likelihood of triggering avalanches is likely increasing due to the substantial amount of warming expected around upper below treeline, treeline, and alpine elevations. Watch out in thin snowpack areas, where the likelihood of triggering deeper layers is the highest.
