Persistent weak layers that formed during an extended drought period in November will be stressed by today's added load and may produce dangerous slab avalanches. As the day progresses the likelihood for humans to trigger large slab avalanches will increase. These dangerous avalanches could be up to three feet deep. To avoid avalanche hazard it is important to identify where the old weak snow exists.
