At the highest elevations isolated pockets of wind slab could be triggered in steep avalanche starting zones. Due to the shallow snow conditions being caught in even a small slab avalanche can have serious consequences. Watch out for areas of unstable snow in isolated terrain features. Snow depths range from 6 to 18 inches at the upper elevations and are generally less than six inches below an elevation of 8,500 feet.
West to southwest winds have formed isolated pockets of dense wind slab up to a foot in depth in very steep northerly facing avalanche starting zones. These pockets have may be human triggered in areas where freshly drifted snow lies upon hard old snow surfaces.
( Discussion is generated from the previous day's afternoon forecast. )Another pulse of moisture is forecast to move across western Wyoming and southeast Idaho overnight and into the morning. This moisture will be accompanied by cooler temperatures and strong southwest to west winds. The freezing level is likely to descend to the valley level by morning. After a bit of a let up in the afternoon, another weaker pulse of moisture will move into the area on Monday evening.The general avalanche hazard is expected to be LOW below an elevation of 9,000 feet and MODERATE at the upper elevations. At the upper elevations pockets new soft slabs six to 18 inches in depth could be human triggered in steep avalanche starting zones.
