Persistent slabs rest on weak, faceted snow and hard snow surfaces. Dangerous slab avalanches to three feet in depth could be triggered by riders and skiers in steep, avalanche terrain. Some steep slopes may be crossed multiple times before a weak spot is encountered causing failure of the slope. Expected warming temperatures will make triggering slides more likely.
