</style><p class="p_CC664AAA"><span class="s_3FE45715">On Friday, natural storm slab avalanches up to size 3 were reported. Skiers and explosives also triggered numerous avalanches. Most of this activity had slab thickness of 20-50 cm but some of the slabs were up to 1 m thick. In the mountains west of Invermere, explosives triggered four persistent and deep persistent slab avalanches on Friday. This activity was on east and southeast aspects and released 1.5-2.5 m deep. On Thursday, a remotely triggered avalanche in the Dogtooth Range broke a few younger trees in the runout.

A lingering weak layer below the recent storm snow may increase the size and propagation potential of avalanches. Extra caution is recommended during the heat of the afternoon, especially on sun exposed slopes. This will become increasingly important on Monday and Tuesday as freezing levels climb. We are entering the first period of substantial warming following months of sustained cold conditions. Any weaknesses lingering in the snowpack will be tested in the coming days.</span></p>
