Humans could trigger large slab avalanches in areas where dense surface slabs lie upon a base of weak faceted snow. These dangerous slabs are more likely to be triggered by a snowmachine but may also be able to be triggered by the weight of a single person on skis or a snowboard.
Dense slab avalanches two to four feet in depth could be human triggered on some slopes at the mid and upper elevations. At the lower elevations pockets of dense surface slab up to 18 inches in depth remain a potential threat in isolated areas.
Overnight, some upper dynamics associated with this front could bring some light snowfall with several inches of accumulation to areas along and east of the Continental Divide while areas west of the divide receive a trace to an inch of new snow. Temperatures will fall into the single digits above zero, west of the divide and below zero east of the divide. On Monday skies will slowly clear, temperatures will rise into the teens and winds will be northwesterly at 10 to 20 miles per hour.Large slab avalanches two to four feet in depth could be human triggered on steep, wind loaded slopes in areas with poor snow pack structure. These events are more likely to occur in the Togwotee Pass and the Greys River areas and less likely in the Teton area. The consequences of being caught and buried by one of these slides could be fatal. The general avalanche hazard is expected to be MODERATE at the mid and upper elevations and be LOW below an elevation of 7,500 feet.
