Tetons

The General Avalanche Hazard is CONSIDERABLE at Upper elevations where five inches of new snow containing .5 inches of moisture has been blown into easily triggered foot deep soft slabs on steep, lee slopes near ridgecrests. The potential remains for slides to step down to deeper, weak layers that could result in dangerous, larger slides. The Hazard is MODERATE at Mid elevations and LOW at Lower elevations. Below 7,500 feet a shallow, early season snowpack exists and avalanches are unlikely but continuous warm temperatures could cause harmful wet sloughs in steep areas like road cuts.

As the current system passes through, cold air is expected to enter the area from the North, resulting in continued snowfall through Thursday afternoon, adding an additional 4-6" to the mountains. Light winds are expected to veer to the North Thursday, while the cold airmass should keep temperatures in the teens.The General Avalanche Hazard is expected to be MODERATE Thursday. Additional light snow, and light winds will increase the surface slab depths to over a foot. Pockets of these surface slabs could be human triggered in steep terrain and carry enough volume to sweep a skier or rider over a cliff edge or burry him in a terrain trap. Large slabs could also be triggered on an old persistent weak layer, particularly in the Togwotee and Greys River areas. These dangerous large slides are less likely to trigger and very hard to predict as they could be released after a slope has been ridden many times.
