Togwotee Pass

The General Avalanche Hazard is CONSIDERABLE. New snowfall and strong Westerly winds at 25 to 35 mph, with gusts near 60, have added weight to existing slabs, which lie atop suncrusts and well developed surface hoar. In addition to the possibility of natural avalanche activity, backcountry travelers could trigger surface slabs up to 2 feet in depth in wind loaded starting zones. This new load has also increased the potential for releasing full depth avalanches on a weak, persistent layer of faceted snow at the base of the snow pack. Avalanche knowledge, excellent route finding skills, and the ability to resist peer pressure are all essential for safe travel in avalanche terrain today.

( Discussion is generated from the previous day's afternoon forecast. )A strong Pacific system is forecasted to impact the region starting Thursday night and continuing into Friday. This storm system could bring three to six inches of new snowfall with accompany strong Westerly winds at 30 to 45 mph. Overnight lows in the mountains should drop to near 10 degrees Fahrenheit.The General Avalanche Hazard is expected to rise to CONSIDERABLE in the TETON, TOGWOTEE PASS/CONTINENTAL DIVIDE, and GREYS RIVER/SOUTHWEST TRAILS areas. In addition to creating whiteout conditions, strong winds and new snow will continue to build upon existing slabs, increasing both their likelihood of failure and the consequences of getting caught. This additional load will also increase the possibility of triggering climax avalanches in the shallow, faceted snowpacks existing in the Togwotee Pass and Greys River areas.
