In sintesi

Sunlight and warm temperatures will weaken the surface of the snowpack today and increase the possibility of triggering existing surface slabs and the potential for wet slides to occur in steep terrain that experiences intense warming. The hazard is anticipated to quickly rise from LOW in the early morning hours to MODERATE once snow surfaces soften. Areas that experienced glide cracks and glide avalanches earlier in the season could become active today and should be avoided. The warm temperatures could activate deeper weak layers in extreme terrain, especially for larger triggers such as snow machines. Caution is advised.

    At the higher elevations pockets of surface slab up to 18 inches in depth lie upon a persistent weak layer of surface hoar and light density snow. In some steep, wind loaded avalanche starting zones these slab are poorly bonded to hard old snow surfaces formed during an extended dry period in February and could be triggered by skiers and riders. Warming temperatures will increase the sensitivity of these slabs to human triggers.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )A few clouds may pass overhead during the evening hours. On Sunday skies will be clear. Temperatures will be similar to today with overnight lows near 20 and daytime highs rising into the 30s and 40s. Winds will be light from the west.Although the snowpack is mostly stable some hazards persist in very steep terrain at the upper elevations and at other elevations on very steep slopes where warm temperatures and sunshine cause significant softening of the snowpack. At the upper elevations pockets of surface slab with depths to 18 inches could be human triggered in steep, wind loaded avalanche starting zones. In the Togwotee Pass area there remains a chance for deep hard slab avalanches to be triggered in isolated areas at the higher elevations. The potential for humans to interact with these hazards will significantly increase as the day warms. At all elevations wet slides are possible on very steep slopes and cliff areas that experience intense warming. The hazard is expected be MODERATE at the upper elevations of the Continental Divide and to rise from LOW to MODERATE in the Teton and Greys River/Southwest Trails areas after snow surfaces soften.
