Tetons

In the last 24 hours 8 to 10 inches of new snow fell at the mid and upper elevations. Storm totals for the past 48 hours have reached two feet. Soft slabs and sloughs to three feet in depth will be easily triggered or run naturally at Mid and Upper elevations on most aspects. Smooth crusts will enable slides to move quickly and entrain large amounts of snow. Sunshine will further destabilize the snowpack making natural activity more likely at all elevations.

Tuesday night will be dry then clouds will increase Wednesday bringing a chance of isolated snow showers to the Tetons while other areas will be dry. Wednesday morning temperatures will be in the teens then warm to the upper twenties by afternoon. Winds will be westerly on the ridge tops at twenty m.p.h.Sun crusts and cool temperatures will help stabilize the new snow. Sloughs could be triggered by skiers on steep, shaded slopes at the upper elevations. Any period of extended sunshine will increase the chance for loose sloughs on sunlit slopes. The avalanche hazard is expected to be Moderate Wednesday in the Tetons and Greys River areas and Low in the Togwotee Pass area. Both the Greys River and Togwotee Pass areas have received less snow through the recent storm cycle but there remains a chance of triggering deeper, hard slabs in very steep terrain at higher elevations in those regions.
