Salt River and Wyoming Ranges

Up to a foot of new snow accompanied with strong southwest winds helped to build fresh slabs in the upper elevations overnight. 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. )Snow showers will continue overnight. Forecasted amounts by 6 am tomorrow are 4-6” in the Tetons, 1-3” on the Continental Divide/Togowtee Pass and 4-6” in the Southwest Trails/Grey’s River area. Lingering showers will add another trace to an inch of additional snow during the day. Ridgetop winds will shift from southwest to west and be in the 15-25mph range. Temperatures will be in the teens at 8,000’ and single digits at 10,000’. While additional snowfall will add some stress to the snowpack, the winds will help to amplify that loading and stress in specific terrain features. Steep high elevation wind loaded slopes will remain the most likely places to trigger avalanches tomorrow. Avalanche activity will remain Low at low elevations, Low to Moderate at mid elevations and Moderate in the upper elevations.
