Salt River and Wyoming Ranges

The general avalanche hazard is CONSIDERABLE today. Heavy, dense new snow and strong winds have created easily triggered or naturally releasing slabs to 18 inches in depth that lie upon hard snow surfaces. Warm temperatures will further weaken the snowpack. Avoid steepening slopes below ridge crests and ravines. Continued warm temperatures have resulted in naturally occurring wet slides in the Snake River canyon. Similar events should be expected or could be triggered in very steep areas today at low elevations like road cuts or ravines.

( Discussion is generated from the previous day's afternoon forecast. )Sunday night into Monday moderate to heavy snowfall is expected with six to nine inches of accumulation in the Tetons and Greys River areas and five to seven inches in the Togwotee Pass area. Winds will be westerly at 30 miles per hour. Temperatures will remain in the upper 20s overnight into Monday. The thin, easily triggered, dense slabs experienced Sunday will grow in depth with the new snow and wind. In the Tetons and Greys River areas backcountry travelers could trigger slabs 12 to 24 inches in depth in steep, lee areas at upper and mid elevations where the avalanche danger is expected to remain Considerable. Naturally releasing slides may be possible.In the Togwotee Pass area there will be an increased chance for users to trigger soft slabs to 14 inches in depth in steep areas of bowls and gullies at upper elevations where the avalanche danger will be Moderate. At Low elevations across the region the chance of human triggered or naturally releasing wet-loose slides is increasing due to warm temperatures and rain in steep areas like road cuts and ravines. The avalanche danger there will be Moderate.
