Points saillants

Low doesn't mean no avalanches. Watch for isolated wind slabs in the high alpine and thin to thick snowpack areas where triggering the deep persistent slab is more likely.

    This is combination of our midseason persistent weak layers and the weak facets & depth hoar that live at the bottom of the snowpack. The likelihood of triggering this layer has been decreasing but if triggered, would likely result in a large destructive avalanche.
