Tetons

At mid and high elevations a chance continues for people to trigger hard slab avalanches to four foot depths in very steep avalanche starting zones that were loaded during the mid January storm. The triggering of these slabs may require large loads such as groups of skiers or snowmobiles. New snow has fallen with very light wind creating the possibility for people to trigger sloughs or very soft slabs to eight inches in depth on steep, high elevation terrain. Avalanches at low elevations are unlikely today

The northern, weaker stream of a split flow pattern will bring light snow to the mountains of Western Wyoming overnight into Monday. Accumulations of three to five inches are possible by Monday night. Temperatures will fall to the lower teens overnight then warm to the upper 20s. Ridge top winds will be northwesterly at 10 miles per hour overnight then westerly at 10 during the day.New snow soft slabs or sloughs to a foot in depth will be easily triggered by people, or periods of sunshine, on steep slopes above 9,000 feet in the Tetons and Wyoming/Greys river ranges. Deeper slab concerns continue as noted above. Larger triggers such as groups or snow machines are more likely to initiate slides. In the Togwotee Pass area slabs of two to four feet in depth could be triggered by snow machines on steep slopes, particularly under cliff areas or just below ridge tops. The general avalanche hazard in all these areas is expected to be MODERATE.
