Tetons

The general avalanche hazard is Considerable at the upper elevations, Moderate at the mid elevations, and Low and the lower elevations. Above 7,500 feet, twelve to eighteen inches on new snow in the last 48 hours has been distributed by southerly winds creating new soft slabs up to two feet deep. These slabs, along with loose snow sluffs, lie upon slick sliding surfaces and could be easily triggered by backcountry travelers in steep, wind loaded avalanche terrain. Any extended periods of sunshine will quickly increase the likelihood of these slides on sunlit aspects. With the exception of shallow wet loose sluffs, avalanches are unlikely below 7,500 feet.

The Pacific low pressure system is expected to shift east bringing six to ten inches of new snow to the Teton and Togwotee Pass areas and up to twelve to the Greys River area through Thursday. Overnight lows in the mountains will be in the mid to low 20s as the valleys dip to near 30, before rising to near freezing up high and into the low 40s down low. Ridgetop winds will back to the northeast at 10 to 20 miles per hour.If forecasted snowfall arrives, the general avalanche hazard above 9,000 feet is expected to be Considerable in the Teton and Greys River areas and Moderate in the Togwotee Pass area; if not, the general avalanche hazard is expected to be Moderate. Backcountry travelers could trigger soft slabs and loose snow sluffs, one to two feet in depth in very steep, wind loaded avalanche terrain. Any extended periods of sunshine will make these slides more susceptible to failure.
