Tetons

New snow and strong westerly winds have created easily triggered soft slabs to 18 inches in depth on steep avalanche starting zones at the upper elevations. The new snow rests on slick crusts. Sunshine will rapidly warm the new snow and wet-loose sloughs, human triggered and natural, should be expected on sunlit slopes. At the lower elevations the snowpack is limited to areas of shallow patchy snow.

A few light snow showers are possible over the peaks tonight with little accumulation. Sunday will be dry with morning temperatures in the low 20s warming to the mid 40s. Winds will be southwesterly at 10 to 15 miles per hour. At upper elevations backcountry travelers could find pockets of soft slab to a foot in depth on steep lee slopes. Warming temperatures will make it easy to trigger wet surface sloughs. The hazard at upper elevations will start at LOW and may increase to MODERATE. Sloughs could grow to dangerous size on very steep, open slopes or where debris could concentrate as in ravines or terrain traps. At mid and low elevations the hazard will be LOW where the snowpack has been through numerous melt-freeze cycles and the snowpack is mostly stable.
