Tetons

Temperatures are 5 to 10 degrees warmer than yesterday morning, and the valley remained above freezing through the night. At the lower elevations, shallow wet loose sluffs will remain possible in areas that did not freeze overnight. In terrain that did freeze overnight, the chance of triggering these small wet slides will develop if surface crusts break down. Isolated pockets of very shallow soft slab could build on leeward slopes near upper elevation ridgelines. Seek colder terrain if crusts start out unsupportable or when they begin to break down, and monitor the possibility of new slab development up high.

As a transitory ridge of high pressure moves into the region, flow aloft will veer to the northwest overnight, and skies will continue to clear with partly cloudy to mostly sunny skies present by Sunday morning. Overnight lows in the mountains will be in the teens before rising back into the upper 20s during the day. Valley temperatures will dip into the low 20s before sunrise and then rebound into the mid 40s in the afternoon. Westerly ridgetop winds will range from 10 to 20 miles per hour.The general avalanche hazard is expected to be LOW Sunday morning. With colder temperatures and partially to mostly clear skies overnight, snow surfaces should experience a hard freeze at all elevations, which will result in a mostly stable snowpack starting off on Sunday. As the day progresses, warming temperatures and sunshine will impact the new snow in the mountains, and very shallow wet loosing sluffing will be likely. Softening of frozen crusts will beginning in the valleys before climbing in elevation as the day warms, particularly on sunlit aspects. Seek out colder terrain when supportable crusts begin to break down to avoid wet loose slides involving the older snow.
