Togwotee Pass

The General Avalanche Hazard is CONSIDERABLE. 8 inches of new snow resting on weak, light density snow has created the possibility of triggering soft slabs to two feet in depth on steep slopes. More snow and wind through the day will increase the size and sensitivity of new slides. Surface slides and/or backcountry travelers could trigger full depth hard slabs on steep, wind-loaded avalanche prone slopes.

( Discussion is generated from the previous day's afternoon forecast. )A strong pulse of moisture from the southwest will move over the area Sunday night bringing strong winds and up to 14 inches of snow to the Teton and Togwotee Pass areas and up to 18 inches to the Greys River area by late Monday. 10,000 foot southwest winds are forecasted to average in the 50 m.p.h. range with gusts in the 70s. A cold upper trough will pass over the region by noon Monday tapering off snowfall rates but lighter snow and strong winds will continue.Very strong winds and rapid snowfall rates will build easily triggered slabs on lee slopes Sunday night through Monday up to three feet in depth. The possibility of triggering deeper slabs that rest on weak, faceted layers will increase in the Greys and Togwotee areas with the new snowfall. The avalanche danger is expected to rise to Considerable or higher in the Teton and Togwotee Pass areas. In the GreysRiver/Southwest Trails area the danger is expected to be High.
