Pockets of wind slab formed by southwest winds could be human triggered today and have depths to 2 feet.
New snow and wind will continue to build slabs that will become more sensitive to triggers as the day goes on. Above 8,500' avalanches will become more likely to trigger in steep wind loaded starting zones. Avalanches involving the new snow have the potential to step down to more deeply buried weak layers in the snowpack. Involvement in avalanches could carry significant consequences due to thin snow cover in many areas and may result in traumatic injury. Avalanches are unlikely in the low elevations.

( Discussion is generated from the previous day's afternoon forecast. )Expect isolated light snow showers overnight. Snowfall will increase in intensity in the early morning hours. Snow will continue through the day and into the evening hours, with forecasted totals by Friday morning in the 8-10” range in the Tetons, 4-6” in the Southwest Trails/Greys River, and 2-4” in the Continental Divide/Togwotee Pass zone. Ridgetop winds will be out of the southwest at 15-20 mph. Temperatures will rise into the mid teens before dipping back into the single digits by nighttime.With loading in the form of snow and wind, expect avalanches to become easier to trigger, especially later in the day. Wind loaded upper elevation slopes will be the most likely areas to find slabs sensitive to human triggers. Avalanches involving the new snow have the potential to step down to deeper layers within the snowpack. While this is on the low end of the likelihood scale, given the variability of the snowpack structure throughout all three forecast areas it should not be ruled out. Consequences of being involved in an avalanche are greater due to thin coverage and could result in traumatic injury. The danger will likely be Moderate at the upper elevations and potentially higher if snowfall amounts exceed tonight’s forecast. The danger will start out Low at the mid elevations and rise to Moderate in the afternoon. The danger at low elevations will remain Low.
