Tetons

New snow expected today is to fall on a mostly stable snowpack. Above 9000 feet, the chance continues for skiers and riders to trigger isolated pockets of shallow slab. This lingering hazard is most likely to be found in steep couloirs and cliff areas where even small slides can have sudden and severe consequences. Avalanches are not expected at the mid and low elevations today.

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.
