Very dangerous avalanche conditions exists and an avalanche warning remains in effect. Over two feet of new snow with about 2.5 inches of moisture has fallen since Thursday. Winds gusted to 66 miles per hour overnight. The Wyoming Department of Transportation used a GazEx unit to trigger a very large slab avalanche in Glory Bowl that ran across the highway. Todays avalanches are expected to be significantly larger and run farther then those that occurred during the previous two days. With continued snowfall and strong winds in the forecast travel in avalanche terrain is not recommended.
Winds slabs two to four feet in depth are likely to release naturally and are very likely to be human triggered on a variety of aspects. These slides could run long distances.
Dangerous persistent slabs lie upon faceted snow and are likely to release naturally today. These very large slabs could have depths of three to six feet and are likely to be triggered by humans or from the release of an overlying wind slab.
Snowfall is expected to continue overnight and into the day with additional accumulations of five to ten inches. Temperatures on Monday will rise into the 20s in the mountains. Winds will be westerly at 20 to 30 miles per hour with gusts to near 50 miles per hour. An avalanche warning remains in effect. Strong west winds and new snow will continue to load avalanche starting zones and cause natural avalanche activity. Natural and human triggered slab avalanches up to four feet in depth are likely and could step down to depths of six feet. The general avalanche hazard is expected to be HIGH in the Greys River/Southwest Trails areas and the higher elevations of the Teton and Continental Divide/Togwotee Pass areas. A CONSIDERABLE hazard is possible at the lower elevations of the Teton and Continental Divide/Togwotee Pass areas. Travel in avalanche terrain is not recommended in areas with high hazard.
