Tetons

Avalanche activity is unlikely today. After several days of warm weather, the snowpack is generally stable and capped with a melt-freeze crust. As new snow falls there could be small sluffs on steep sustained slopes. Today's hazard will be safely moving through the mountains with the challenging snow conditions that currently exist.

The storm system passing over Nevada toward the four corners is expected to mainly affect the southern portion of the forecast area and stay east of the divide. Temperatures will be cooling over the week, and tomorrow will be in the low to mid-teens at 10,000 feet and teens to twenties in the valleys. Light to moderate winds will vary from south to east to north. Accumulation amounts by Sunday evening could be 10 to 12 inches in the Salt and Wyoming Ranges and three to five inches for the Togwotee Pass and Teton forecast areas.The avalanche danger will increase with the new snowfall. In the Tetons and Togwotee Pass forecast areas, limited snowfall will keep the hazard Low, and avalanche activity will remain unlikely. For the Southwest Trails forecast area, periods of moderate to heavy snowfall will increase the potential for small storm and wind slab avalanches, and the hazard may increase to Moderate by the afternoon. Backcountry travelers should monitor the storm as some areas may receive heavier snowfall and stronger winds.
