Southwest to west-northwest winds have formed new soft surface slabs up to two feet in depth on leeward aspects. These soft slabs are likely to be easily triggered by humans. Instabilities persist associated with deeply buried layers of faceted snow and November rain crusts. The potential remains for humans to trigger dangerous hard slabs up to six feet in depth. These deep hard slabs exist on a variety of aspects. Conservative decisions regarding terrain selection are warranted.

Another quick hitting storm system will bring 4 to 7 inches of accumulation to the mountains overnight then just light snow during the day Monday. Winds will be westerly at 20 to 25 miles per hour and temperatures at 9,500 feet will drop to the low teens Monday morning then rise to the low twenties during the day.The General Avalanche Hazard will be CONSIDERABLE Monday. Available and forecasted light density snow will be drifted into easily triggered soft slabs to two feet in depth on lee slopes. Deep slab instabilities lurk in the depths of the snowpack but are likely to require larger triggers like multiple riders on a slope. In the Continental Divide/Togwotee Pass area weak, faceted snow at the base of the snowpack has been the cause of several dangerous, hard slab avalanches on Angle Mountain that have been triggered remotely by skiers and snowboarders. Other steep areas in that region have similar conditions and the new snow will make triggering deep slides by riders likely.
