Tetons

At the high elevations, the chance for skiers or riders to trigger pockets of wind slab continues in very steep terrain. If predicted snowfall and strong northwest winds occur, these slabs could increase in size and very shallow surface slabs could develop and be sensitive in areas where they form upon hard crusts. At the mid and lower elevations, avalanche activity is not expected other than in isolated pockets between an elevation of eight and nine thousand feet.

Dryer air and cooler air will move in from the northwest along with some lingering snow showers. On Thursday skies will be partly cloudy. Temperatures will drop into the single digits overnight and rise into the upper teens and 20s during the day. Winds will be from the north at 15 to 25 with gusts to 40 miles per hour.The general avalanche hazard will continue to be moderate at the upper elevations of the Teton area and at the mid and upper elevations of the Greys River and Togwotee Pass areas. It will be low at the mid and lower elevations of the Teton area and at the lower elevations of the Greys River and Togwotee Pass areas. Persistent slabs 3 to 6 feet deep are still a concern in the Greys River and Togwotee Pass areas. These dangerous hard slab avalanches could be triggered by snowmachines on very steep avalanche prone slopes. At the higher elevations wind slabs 1 to 2 feet in depth could be triggered by the weight of a single person.
