Tetons

The general avalanche hazard is MODERATE at the upper elevation where pockets of slab to 1 foot in depth could be triggered in wind loaded starting zones. As temperatures increase, along with the possibility of some sunshine, point slides could be seen at the high and mid elevations. At low elevation, freezing overnight temperatures have created a supportable crust that will breakdown with daily warming, allowing wet slide activity, and increasing the hazard to MODERATE.

A flat ridge of high pressure will continue to build in tonight, resulting in mostly clear skies tomorrow. In the mountains, overnight lows should be in the teens before rising into the mid 30s. In the valley, temperatures should dip into the high teens tonight, before rebounding into the high 40s by the afternoon. AVALANCHE HAZARD FORECAST FOR THE TETON, TOGWOTEE PASS, AND SOUTHWEST TRAILS AREAS:The general avalanche hazard tomorrow morning will be LOW before quickly rising through MODERATE to CONSIDERABLE by the afternoon. Cool overnight temperatures will temporarily stabilize the snowpack at all elevations. As temperatures rise, along with sunshine, three concerns will be on the increase. At lower elevations, the possibility of point slides and wet slabs will increase throughout the day. With a gain in elevation, sloughing of new snow on sunlit aspects will be possible that has the potential of entraining dangerous volumes of snow. Finally, pockets of slab could be triggered on shaded aspects in wind loaded starting zones. Cornice drops could also act as a trigger for each avalanche scenario.
