The general avalanche hazard is Moderate above 9,000 feet and low below that elevation. At the higher elevations, a remote chance continues to trigger deep hard slabs in isolated steep avalanche paths. Avalanches below 9,000 are not expected today.
Weak snow persists near the base of the snowpack. In isolated areas, dangerous hard slabs with depths to 40 inches could be human triggered on this layer. This basal weakness is limited in distribution and is most likely to be found in the higher elevations along the east slope of the Wyoming Range.
( Discussion is generated from the previous day's afternoon forecast. )Periods of rain and snow are possible overnight with additional accumulations of another inch or two likely at the higher elevations. Skies on Monday are expected to be partly to mostly cloudy with lingering chances of light snowfall in the mountains during the morning hours. The freezing level is forecast to descend to the valley level overnight and rise to around 7,500 feet during the day. Winds are forecast to increase to around 25 miles per hour with higher gusts and veer to the west-northwest.In the Togwotee Pass and Greys River forecast zones isolated areas of deep instability may persist in some upper elevation avalanche paths. Although the snowpack is mostly stable the general avalanche hazard is expected to be MODERATE, above an elevation of 9,000 feet, in those forecast zones due to those isolated instabilities.In the Teton area increasing winds will begin to form small pockets of wind slab 4 to 8 inches deep in steep upper elevation avalanche starting zones. These small slabs and loose snow sluffs could tip a person over and carry them, long distances in extreme terrain. It is anticipated that the general avalanche hazard will be LOW. Greater than forecast snowfall amounts would increase the hazard at the upper elevations.
