Tetons

The wind is redistributing new snow that has fallen in the last few days. Isolated wind loaded pockets 8-10” deep may pose a hazard on very steep, high elevation terrain. Loose dry avalanches may be found on sustained slopes over forty degrees. Both of these hazards are expected to be small and isolated. Only expose one person at a time to hazards and evaluate your routes and safe zones carefully.

Cloud cover will increase overnight with light snow showers developing by morning. Snowfall will continue during the day with accumulations around 1-2” in the mountains. Temperatures between 8,000-9,000 feet will dip into the low twenties tonight before climbing back into the upper twenties during the day tomorrow. Ridgetop winds will be in the 20-25 mph range overnight out of the west. Wind speeds will diminish slightly tomorrow with average speeds of 15-20 mph.The avalanche danger will remain Low tomorrow. The exception to this will be in steep upper elevation terrain where it will be possible to find isolated pockets of shallow wind slab. With new snow in the forecast, it will be important to remember what the current snow surfaces are. The 2-4” of new snow from this past week fell on slick sun crusts, wind pressed snow, sastrugi as well as facets and surface hoar. Strong winds today helped to create more variability of snow surfaces. Keep this in mind as slabs begin to slowly build tomorrow and into Monday and Tuesday.
