Tetons

The upper elevations received up to five inches of dense new snow during the past 30 hours. This new snow was accompanied by strong winds. The freezing level has ranged from 8,000 to 9,500 feet with scattered rain showers below these elevations. Mountain temperatures dropped into the mid to low 30s overnight. Areas of rain soaked snow exist. At the upper elevations areas of wet snow exist immediately beneath the new snow. Isolated pockets of new wind slab up to ten inches deep exist in the highest avalanche starting zones and pose a threat to skiers, riders and climbers who venture into steep couloirs and cliff areas. Wet loose slides involving the new snow are likely on very steep slopes and in cliff areas. These point slides could be human triggered or release spontaneously. Large dangerous wet slides continue to be a threat and could be triggered by a cornice failure, a small wet loose slide or release spontaneously. Wet slides could entrain large volumes of snow and become destructive. The potential for these slides to run long distances poses a threat to humans who travel and camp in the snow covered cirques, canyons and basins of the Teton Range. This advisory does not extend above an elevation of 10,500 feet. Very little snow exist below an elevation of 7,500 feet.
