Tetons

Cycles of warm days and below freezing nights have resulted in a snowpack that is mostly stable this morning. In high elevation terrain, a slight chance exists for humans to trigger small, isolated pockets of soft slab in a few shaded, very steep terrain features. As direct sunlight and rapidly warming temperatures weaken the bonds of the surface crusts, wet slide activity will become possible this afternoon. Above 9000 feet, this activity will only involve the recent snow that fell last week. As elevation lowers, any moving snow could en-train deeper layers of the snowpack. Exit avalanche terrain before the snowpack is to warm for safe travel and follow social distancing protocols in the backcountry, at access points, and while travelling to those areas.

Tonight and Wednesday morning are to be clear and dry before clouds increase and precipitation returns on Wednesday afternoon. Below freezing temperatures are expected at all elevations overnight with highs to be similar to today before the precipitation begins. That means that storm will start as rain potentially as high as 9000 feet before the rain/snow lines drops towards the valley during the evening and Wednesday night. In the morning, the general avalanche hazard will be Low at all elevations and avalanche activity is not expected in the mostly stable snowpack that will be topped with a hard, supportable crust. The danger could increase to Moderate during the afternoon in steep terrain after the snowpack is first weakened by sunlight and warm temperatures and then additionally weakened by potential rain.
