GENERAL AVALANCHE ADVISORY

Warm temperatures and abundant sunshine will cause the hazard to increase throughout the day. Slab avalanches lie upon persistent weak layers and will become increasingly sensitive to human triggers as the day progresses. Yesterday, a skier in Grand Teton National Park triggered a slab avalanche on a lower angle slope. Similar events are possible today, especially after snow surfaces soften.
