Salt River and Wyoming Ranges

At the higher elevations, the general avalanche hazard is MODERATE this morning and will increase to CONSIDERABLE during the day. Warming temperatures, dense new snow and strong southwesterly to westerly ridgetop winds will continue to build surface slabs which rest on slick sliding surfaces and lighter density snow. In steep, wind loaded terrain, skiers and riders could trigger these slabs up to two feet deep by this evening. Prolonged periods of afternoon rain could also bring about the possibility of wet slides at the lower elevations.

( Discussion is generated from the previous day's afternoon forecast. )Snowfall will become widespread by the morning and continue through the day on Tuesday. Strong westerly to southwesterly ridgetop winds will increase to 30 to 40 miles per hour overnight and continue throughout the day. Overnight lows in the mountains will be in the upper teens rising to near freezing in the afternoon. Valley highs will be in the low 40s with rain or a rain/snow mix likely during the day.At the higher elevations of the Teton and Greys River areas, the general avalanche hazard is expected to be MODERATE Tuesday morning and could rise to CONSIDERABLE in the afternoon with forecasted strong winds and snowfall. There, newly formed pockets of soft slab, which lie upon slick sliding surfaces, will continue to build. Backcountry travelers could trigger these slabs up to 18 inches deep in steep, wind loaded terrain by the afternoon. At the lower elevations, extended periods of rain could result in wet slide activity.In the Togwotee Pass area, the general avalanche hazard is expected to be LOW in the morning and could rise to MODERATE later in the day as pockets of soft slab build up to a foot deep. Skiers and riders could trigger these slabs on steep, wind loaded slopes in exposed terrain.
