Tetons

Temperatures have increased about 12 degrees over the past 24 hours. Pockets of new soft slab 12 to 18 inches deep, formed by west-northwest winds, lie upon surface hoar, light density snow and crusts. Yesterday skiers triggered these slabs in the Chicken Scratch Couloir on Mt. Glory, in Spacewalk Couloir south of the boundary of the Jackson Hole Mountain Resort and near the base of 25 Short in Grand Teton National Park. Similar events could be human triggered today on steep avalanche prone slopes. Careful assessment of terrain and the snowpack is essential.

Mostly cloudy skies with limited moisture will continue to stream over a ridge to our west and into our area. Periods of light snowfall or flurries with little accumulations are possible overnight and during the day on Friday. Temperatures will drop into the teens at elevation and into the single digits above zero in the valleys overnight. Daytime highs will rise into the 20s on Friday. Winds will be west to northwest at 5 to 10 miles per hour.The general avalanche hazard is expected to be MODERATE. Surface slabs up to 18 inches in depth exist and could be triggered by the weight of a single person. Caution is advised on steep slopes.
