Tetons

At the mid and upper elevations, four to six inches of new snow driven by westerly and southwesterly winds have formed six to twelve inch new soft slabs. These slabs, which lie upon a mostly stable snowpack, could be triggered by backcountry travelers venturing into steep, wind-loaded starting zones. At the lower elevations, mostly stable snow exists and avalanches are unlikely.

Southwesterly ridgetop winds at 20 to 35 miles per hour will continue through Saturday night, and then increase during the day on Sunday as snow showers start to develop. Three to five inches of new snow could be seen by Sunday evening. Overnight lows in the mountains will be in the low teens before rising into the low 20s on Sunday.The general avalanche hazard is expected to remain MODERATE in the Teton area where 6 to 18 inch soft slabs could be triggered by backcountry travelers in steep, wind-loaded terrain.The general avalanche hazard in the Togwotee Pass/Continental Divide Trails Area is also expected to remain MODERATE. Backcountry travelers could trigger slab avalanches on steep slopes that are underlain by weak, faceted snow. These avalanches have potential to step down to the ground.The general avalanche hazard in the Greys River/Southwest Trails Area is expected to remain CONSIDERABLE. In steep terrain, backcountry travelers could trigger dangerous slabs lying upon a base of weak, faceted snow.In all areas, the general avalanche hazard will increase during the day on Sunday as new snow and strong winds combine to create new surface slabs and add weight to existing weak layers.
