Tetons

Abundant sunshine and warming temperatures will heat up snow surfaces as the day progresses. This warming will first increase the likelihood of triggering recently developed wind slabs up to a foot deep in steep, wind-loaded terrain above 8,500 feet. As the day continues to warm, the chance for wet slides involving the recent snowfall will develop on sunlit aspects. While avalanche activity is likely to initially be small, a significant amount of snow could be entrained by these slides in long, steep chutes and couloirs. The emergence of rollerballs and pinwheels will be good indicators that it is time to seek out cooler terrain. The daily morning avalanche nowcasts will conclude on Sunday for the 2016-2017 winter season.

Clouds will be on the increase after midnight as the first in a series of disturbances will begin to move into the region. On Sunday skies will be overcast. Snow and rain showers are likely by evening. Temperatures will drop into the 20s and low 30s overnight and rise into the 40s and 50s during the day. Winds will be southwest at 15 to 20 miles per hour with higher gusts.At the upper elevations pockets of wind slab up to a foot in depth could be triggered by skiers in steep wind loaded avalanche starting zones. Wet slides involving the recent new snow are also possible on very steep sunlit slopes. The potential for humans to trigger these wind slabs and for shallow wet slides to occur will increase as the day warms. The general avalanche hazard at the upper elevations (9,000 to 10,500 feet) is expected to be low in the morning and increase to moderate as the day warms. Avalanches are unlikely below an elevation of 9,000 feet.
