Salt River and Wyoming Ranges

The general avalanche hazard is LOW this morning and could rise to MODERATE in the afternoon. Backcountry travelers might be able to trigger isolated pockets of slab up to two feet in depth on very steep, northerly slopes. Once again, the hazard will be dependent on the amount of sun impacting the snowpack. If skies clear early in the day, the hazard will increase on sunlit aspects in the afternoon. Once crusts break down, backcountry travelers could trigger slabs up to 3 feet deep on steep, avalanche prone slopes.

( Discussion is generated from the previous day's afternoon forecast. )A weak weather system could bring a few inches of new snow to the mountains overnight before a transitory ridge of high pressure builds during the day on Monday. Overnight lows in the mountains will be in the upper teens before rising to near 30 during the day. Southwesterly to westerly ridgetop winds will range from 20 to 30 miles per hour.In the Teton and Greys River areas, the general avalanche hazard is expected to be LOW Monday morning. Strong winds and a few inches of new snow could build isolated pockets of very shallow wind slab in exposed terrain near upper elevation ridgelines. Once again, the hazard will be dependent on the amount of sun impacting the snowpack. If skies clear early in the day, the hazard will increase to MODERATE on sunlit aspects in the afternoon. There, loose sluffing of the new snow will precede the weakening of older snow. If crusts break down, backcountry travelers could trigger slabs up to 3 feet deep on steep, avalanche prone slopes. While similar to the other areas, the Togwotee Pass region has a shallower and weaker snowpack, and the general avalanche hazard is expected to be MODERATE. Backcountry travelers could trigger isolated areas of slab up to three feet deep in steep, avalanche terrain. Any extended periods of sunshine will make these slabs more easily triggered on sunlit slopes.Take note of the sun's effect on snow surfaces, and move to shaded terrain before the upper portion of the snowpack becomes wet.
