Salt River and Wyoming Ranges

The General Avalanche Hazard is MODERATE. A shallow snowpack with buried weak layers of faceted snow exists. Backcountry travelers could trigger slabs up to two feet in depth on steep avalanche starting zones. These unstable slabs are most prevalent on upper elevation (above 9,000 feet) northerly and easterly aspects. Avalanches are unlikely below an elevation of 8,000 feet due to shallow snow depths.

( Discussion is generated from the previous day's afternoon forecast. )Tuesday evening into Wednesday a fetch of Pacific moisture will bring 4 to 8 inches of snow to the Tetons and Salt/Greys River areas with deeper accumulations at the higher elevations. Winds will be from the Southwest at 15 to 20 miles per hour and 9500 foot temperatures will rise to the low twenties. The Togwotee Pass/Continental Dive area will receive 3 to 4 inches of snow. The General Avalanche Hazard is expected to be CONDSIDERABLE Wednesday in the Tetons and Greys River areas. Although winds are not forecasted to be strong enough to create a high risk of wind slabs, the continuing build-up of snow will increase the chance of triggering slides in areas that developed weak, faceted surface snow in the clear period last week. These layers are mostly in shaded and easterly aspects around 8000 to 9500 feet. Areas of slabs to two feet in depth could be triggered below the higher ridge crests that experience stronger winds or other areas where deeper snow accumulates such as under cliffs. Deeper hard slabs, which lie upon weak, faceted snow, persist primarily in the Togwotee Pass and Greys River areas, and could still be triggered on easterly and northerly aspects.
