Persistent slabs to three feet in depth rest on weak, faceted snow and hard snow surfaces at the mid and upper elevations and around a foot deep at the lower elevations. These dangerous slabs could be triggered by people in steep, avalanche terrain. Some steep areas may be crossed multiple times before a weak spot is encountered causing failure of the slope. Periods of extended sunshine will make slides easier to trigger.
