Backcountry riders and skiers have the potential to trigger recently formed shallow surface slabs or sluffs as well as persistent slabs that lie upon weak faceted snow at the base of the snowpack. Greatest areas for concern for these larger events are steep avalanche starting zones and terrain in and around cliffs. Avalanches below 7500 feet are unlikely.
On some steep slopes slabs up to three feet deep lie upon weak snow near the base of the snowpack. These slabs could be triggered by a rider or skier even after a slope has been tracked.
( Discussion is generated from the previous day's afternoon forecast. )A Pacific low pressure system passing to the south of the region will provide limited moisture to the area starting after midnight and continuing through Friday. In the mountains accumulations could reach as much as seven inches in some areas with lower elevations receiving lesser amounts or possibly a mix of rain and snow. Winds are to be light with this system and mountain temperatures are to reach the upper twenties during the afternoon. The general avalanche hazard is expected to be Moderate. Surface slabs to two feet could be triggered in steep terrain in the Tetons. In the Southwest Trails/Greys River and the Togwotee Pass areas harder slabs to three foot depths could be triggered where they are underlain by weak faceted snow.
