Tetons

The hazard at all elevations will increase as the day warms. Wet loose and wet slab avalanches up to two feet in depth could occur on steep slopes. These events could be human triggered or release naturally and are most likely to occur on very steep slopes with a shallow snowpack that is underlain by faceted snow. At the upper elevations humans could also trigger isolated pockets of wind slab up to a foot deep in steep avalanche starting zones, couloirs and cliff areas.

Cloud cover is expected to increase during the day on Sunday as a Pacific low pressure system tracks to the south of the region. Overnight lows in the mountains will be near 20 before rising into the mid 30s during the day. Ridgetop winds will be out of the southeast at 10 to 20 miles per hour.The general avalanche hazard is expected to be: LOW during the morning in the Teton area where backcountry users have the potential to trigger isolated pockets of surface slabs to twelve inch depths in steep, shaded terrain. MODERATE in the Togwotee Pass area where the possibility persists for skiers and riders to trigger full depth hard slabs in very steep terrain. Larger triggers, such as snowmachines, may be necessary to initiate such an event. MODERATE in the Southwest Trails/Greys River area where backcountry travelers have the potential to trigger full depth hard slabs in steep terrain as well as surface slabs to twelve inches in depth on very steep shaded slopes. Any extended periods of sunshine will weaken the snowpack and wet slides could become possible on sunlit aspects in all three areas.
