Salt River and Wyoming Ranges

The General Avalanche Hazard is LOW this morning and will rise to MODERATE by mid day. Low temperatures have helped cool the snowpack but new snow to 4 inches will prevent the development of stabilizing crusts. Any sun breaks or rising rain levels will cause sloughs of the new snow and begin warming the old. Sloughs or riders could cause dangerous, deeper snow to slide. Stay out of ravines and road cuts at lower elevations and avoid run-out zones of higher slide paths.

( Discussion is generated from the previous day's afternoon forecast. )A cold front will move into the region by Tuesday evening bringing cooler temperatures and snow to the mountains. Snow will spread to the valley floor overnight. 2 to 4 inches of accumulation is expected in the Tetons by Wednesday morning. Heavier snowfall with 3 to 6 inches is expected in the Greys River Range and 1 to 3 inches in the Togwotee Pass areas. Winds will become strong with frontal passage overnight with ridge top winds from the Southwest at 30 miles per hour. Snowfall will become light and scattered during the day Wednesday with mountain temperatures reaching 30 degrees. Rain on the valley floors in the evening will turn to snow overnight with a trace to 1 inch of accumulation.With the coldest forecasted temperatures in over two weeks the snowpack will cool with strong surface crusts dropping the Avalanche Hazard to LOW Wednesday. The new snow, however, will hold heat in the older snow and any sun breaks will cause sloughing of the new snow and possibly entrain older snow increasing the Avalanche Hazard. Local areas with warmer temperatures could also see an increase in the chance of larger slides.
