Salt River and Wyoming Ranges

The General Avalanche Hazard is MODERATE. Deep, weak layers of faceted snow persist in steep areas with a shallow snowpack and could fail to the ground under the weight of a skier, snowmachine, or groups of skiers or snowmachines. Yesterday a three foot deep hard slab avlalanche 25 yards wide released behind a snowmobile traversing(not high marking)a northeast facing slope in the Man Bowl area of the Snake River Range. The small bowl had eight old tracks and one new track before it released. The Greys River/Southwest Trails area has a similar snowpack and such events could be triggered today with severe consequences.

( Discussion is generated from the previous day's afternoon forecast. ) A weak ridge of high pressure will keep skies clear through Tuesday night. 10,000 foot high temperatures could reach the freezing point. Ridgetop winds will back from northerly to westerly and increase to 35 mile per hour averages by evening.The General Avalanche Hazard is expected to remain MODERATE in the Tetons where isolated pocets of surface slabs to 12 inches are possible. In the Continental Divide/Togwotee Pass and the Southwest Trails/Greys River areas the Hazard will be MODERATE but the primary concern is for deeper, hard slab avalanches.
